ELV Systems

What are Extra-Low Voltage Systems (ELV)? 

Extra-Low Voltage means the voltage of electricity supply is in a range that is low enough that it does not carry any high risk of any high voltage electrical shock(s).

The range of voltage that can be classified as Extra-Low Voltage is alternating current not exceeding 50 V AC and direct current not exceeding 120 V DC (ripple free). This is based on the standards as per EN 61558 or BS 7671.

The term extra-low voltage ("ELV") means an operating voltage not exceeding 50 Volt alternating current (a.c.) or 120 Volt ripple free direct current (d.c.) as defined in Australian / New Zealand Standard AS/NZS 3000.

Therefore, Extra-Low Voltage Systems are any electrical systems that can operate on a low voltage with the voltage criteria as per above.

Key Characteristics

·        Low Voltage:The most defining feature is their safe, low-voltage operation, which reduces the risk of electric shock. 

·        Non-Core Systems:ELV systems are separate from the building's main, high-voltage electrical power system. 

·        Integrated Technologies:They are the "smart" components of a building, connecting devices and managing data. 

In this article, we are going to share more about different components of ELV systems.

Components of ELV Systems

Video Surveillance System:

Video-surveillance systems, also more commonly known as Closed Circuit Television, in short "CCTV", is made up of a network of cameras and recording systems that are connected to each other. This system would be classified as a ‘closed’ system as the system operates independently, unless it’s part of an ELV integrated system. A CCTV system is an effective way to monitor and secure any sensitive area(s).

Currently, cameras can be connected either wired or wireless to a CCTV system. CCTVs are an effective deterrence to any threats or area(s) that require constant offsite monitoring.

The key points in installing CCTV cameras is the positioning of the camera, to ensure that the camera can monitor the required area in its scope of view as well as the clarity of the video footage to ensure usability of the footage if necessary.

Access Control System – ACS:

Access control systems are a key feature of any security system hub that can secure, monitor and manage the access of staff in any type of building. With this system, staff can either be given access cards or using fingerprints(biometric), they are able to be granted access to various areas of the premises.

Nowadays, these systems ‘speak’ to each other wirelessly and usually connected to the local area network to reduce hard wiring cost and flexibility of the positioning of the system itself. At times, the access control system might be a part of a bigger integrated ELV system which allows central control of multiple different systems.

Public Address Voice Alarm System – PAVA:

A public address system is a system that allows an amplification of your voice through microphones and loudspeakers. Its purpose is to enhance the volume of human voice or any other sound for that matter.

The general alarm system allows remote control of alarms and flashing lights(beacons).

Combined, this system would serve a general use of relaying information or be used in the case of any emergency evacuations.

Fire Detection & Alarm System - FDAS:

Fire Alarm Control Panel is the brain of the system. Receives input from detectors, Manual call points & sends output to sounders/bells.

ELV fire alarm systems can provide early warning of fires in public and state facilities, allowing for prompt evacuation and reducing the risk of injury or death. These systems can also be integrated into building management systems to provide automatic fire suppression, such as sprinklers or fire extinguishers.

LAN and IP-BX System:

LAN stands for local-area network and is basically an interconnected computer network that usually covers a small area. This network of computer/devices can be connected to each other via physical wires called LAN cables or wirelessly (radio waves).

A telephone system is a group of interconnected telephones connected either via telephone lines or via LAN cables which then communicate using ‘Voice over Internet Protocol’ or in short VoIP.

Intrusion Alarm System - IAS

An intrusion alarm system — also known as a burglar alarm system — is an important security measure that can protect your business from unwanted intruders, theft, vandalism, and property damage.

Intrusion alarm systems provide several key benefits for businesses, such as increased safety for building occupants, faster response times to breaches, and lower insurance premiums. By investing in an intrusion alarm system, you are taking a proactive approach toward the safety and security of your property.

Nurse call system - NCS

A nurse call system is a healthcare technology solution in hospitals and nursing homes that allows patients to request assistance from staff by pressing a call button or using a pendant. These systems feature call buttons, receiving units at the nurse's station, and often wireless devices like pagers or watches to notify nurses in real-time. The primary goal is to ensure timely patient care, improve safety by reducing response times, and enhance staff efficiency through features like real-time alerts and reporting.

Trunk Radio System – TRS

A trunk radio system is a system whereby all available radio channels are placed in one single pool. When for example person A requires to transmit, a channel is automatically picked from the pool and used for person A’s transmission. Once the transmission is completed, the channel that person A was using will be placed back into the pool for others to use.

This system is highly beneficial as radio channels are limited by nature as for example, if all radio channels are taken up, we can’t physically or manually ‘create’ new channels. By using a trunk radio system, it’s more efficient in a sense there is a higher chance a user will get access to an available channel when required.

Home Automation System -  HAS:

Home automation is nothing but the mechanical management and administration of intelligent electronic appliances in a house. Sequencing pre-programmed smart devices to meet the unique needs of the residents is what a home automation system does.

In a home automation solution, devices can trigger each other without any human intervention. Furthermore, it allows users to schedule automated processes like switching the lights, controlling the temperature, calibrating the entertainment system, and more. What is home automation? It is an integrated system that makes life more convenient and helps in saving a variety of costs.

Fence Intrusion Detection System – FIDS

A fence intrusion detection system or FIDS for short is a security system whereby the key purpose of this system is to be able to detect any breaches that occur on any perimeter fences.

There are multiple sensors installed on different parts of the fence so whenever an intrusion is detected in a certain fenced area, if there is a CCTV nearby, the security personnel would be able to angle the CCTV to view the intrusion if possible. If necessary, a physical check on the fence is needed as well to ensure the security and integrity of the perimeter.

Building Management System - BMS:

Building Management Systems (BMS) that integrate and control various building functions. There are multiple sensors installed on different parts of the utility system. BMS Engineer control all utility system from single room. Building Management System also known as IBMS and BAS in Americas and the European countries.

IO Points are further categorized into analogue & digital, with suitable field devices. & sophisticated third party devices fixed in a building ranging from grounding an elevator to monitoring the water level of a sump to monitoring & controlling the properties of HVAC (Heating, Ventilation & Air Conditioning) equipment that is the Temperature, RH, Pressure.

Water Leak Detection (WLD) system:

Early Water Detection is essential in a lot of businesses, for example, data centers, industrial sites, offices, hotels, residential buildings, and more. With the right detection of water and early alert, costly water damage can be avoided. HW group offers several products that provide ideal solutions for Water Leak Detection (WLD) that are developed to protect your facility against any water damage that might threaten you.

Water Leak Detection uses a sensing cable that detects water along the entire cable length and a WLD device (WLD2 / NB-WLD / ...) that can communicate an alarm in case of water occurrence (a few drops anywhere on the cable is enough).

Master Clock System – MCS:

A master clock system is an interconnected system of clocks whereby slave clocks would take reference of time from a reference clock, also known as a master clock. These slave clocks would synchronize their time with the master clock. In this way, the time across both the master and slave clocks would be the same.

The use of master clock systems can be used in a variety of industries such as for the IT sector and military or anywhere that requires an extremely high degree of time accuracy.

Rodent Repellent System:

Rodent repellent is a device unit that emits ultrasonic sound waves to create an acoustically hostile environment that repels rodents. This helps to keep your Data Center free form rodents. Frequency of sound will induce rodents to move away from Data Center premises. As per research by University of Nebraska, Rodent Repellent is a proven device. Rodents under test could either leave the buildings or move to alternate non-ultrasonically treated areas.

As Data Center is the important business premises, we need to protect it from many risks.

Exit Stopper Door Alarms:

The highly effective Exit Stopper can serve as an inexpensive security device and help stop theft by alerting you to any unauthorized exits or entries through emergency exit doors. Standalone fire exit stopper alarm with one relay for integration with fire alarm system.

Professional Display & Signage

Professional display screens are high-quality, commercial-grade screens specifically designed for continuous use in business settings. Unlike consumer-grade TVs, they’re engineered to operate reliably for extended hours, often supporting 24/7 use without compromising on display quality or durability. Professional displays come with advanced features like remote content management, high brightness, and enhanced connectivity options, making them ideal for business environments.

ELV digital signage systems can provide real-time information, such as maps, directions, and event schedules, for tourists. This can improve convenience and enhance the overall experience by providing accurate and up-to-date information.

GRMS System:

Operates light management (on, off, or dimmer), automatic curtain openings (including blinds and rolling shutters), HVAC, TVs, and “do not disturb” or “make up room,” alerts based on the presence or absence of the guest in the room.

Mobile Phone and Wireless Distribution: 

Seamless connectivity, accessibility, and communication throughout a building.

Vehicle Tracking System

The GPS based Vehicle Tracking System comprises of an in-vehicle tracking system that consists of a GPS receiver unit, CDMA/GSM Modem, on-device Data Storage unit, other peripherals, and a web-based application. Through this system, the users will have the facility to monitor the movement and gather entire information of any vehicle.

IoT:

The IoT provides the connectivity that enables real-time monitoring and control of building systems, both on-site and remotely. With IoT-enabled BMS, building operators can monitor and control systems from anywhere, anytime, through a single user interface. This allows for greater efficiency, cost savings, and improved building performance.

In smart infrastructure, ELV systems, BMS, and IoT play a similar role in optimizing and monitoring the performance of critical infrastructure systems, such as energy grids, water supply networks, and transportation systems. These systems can be monitored and controlled in real-time to improve efficiency, reduce costs, and ensure reliability.

Role of IOT in improving ELV systems

The Internet of Things (IoT) can significantly improve ELV (Extra-Low Voltage) systems. IoT technology can connect and monitor ELV systems, providing real-time information, control, and automation capabilities.

Here are some ways in which IoT can improve ELV systems:

1.   Monitoring and Control: IoT devices, such as sensors and actuators, can control ELV systems, such as lighting, HVAC, and security systems. This can provide real-time information and allow for remote control of these systems, improving efficiency, comfort, and security.

2.   Predictive Maintenance: IoT technology can collect data from ELV systems and analyze it to predict when maintenance is needed. This can improve system reliability and reduce downtime, increasing efficiency and reducing costs.

3.   Energy Management: IoT technology can monitor and control energy consumption in ELV systems, reducing waste and improving energy efficiency. This can contribute to sustainability and reduce costs.

4.   Integration: IoT technology can integrate ELV systems with other building management systems, such as BMS (Building Management Systems), providing a more comprehensive and integrated solution.

5.   Real-time Analytics: IoT technology can collect and analyze real-time data from ELV systems, providing valuable insights into system performance and usage patterns. This can help to optimize system operation and improve decision-making.

Role of AI in ELV systems

Artificial Intelligence (AI) is playing an increasing role in ELV systems, including lighting control, building automation, audio and video systems, security systems, and more. AI can be used to improve the performance, efficiency, and intelligence of ELV systems in several ways:

1.   Predictive Maintenance: AI can analyze data from ELV systems to predict when maintenance or repairs will be required. This can reduce downtime and improve the overall reliability of the systems.

2.   Energy Efficiency: AI can optimize energy consumption in ELV systems, such as lighting control systems. For example, AI algorithms can analyze occupancy patterns and adjust lighting levels accordingly to reduce energy consumption.

3.   Real-Time Monitoring: AI can monitor ELV systems in real-time, providing early warning of potential issues and allowing for proactive maintenance and repairs.

4.   Automated Decision-Making: AI can automate decision-making processes in ELV systems, such as lighting or HVAC control. For example, AI algorithms can automatically analyze weather data and occupancy patterns to adjust heating and cooling levels.

5.   Improved User Experience: AI can improve the user experience of ELV systems, such as voice-controlled lighting control systems or personalized audio and video systems.

Role of cyber security for ELV systems

Cybersecurity is critical for ELV systems due to the sensitive nature of the systems and the potential consequences of a security breach. ELV systems are integrated into building management systems and often control essential functions, such as lighting, heating, ventilation, air conditioning, and security systems. Therefore, a breach of an ELV system can result in unauthorized access, loss of sensitive information, or disruption of critical building functions.

Here are some ways in which cyber security is essential for ELV systems:

1.   Protecting Sensitive Information: ELV systems often contain sensitive information, such as building plans, access codes, and security camera footage. Cybersecurity measures are necessary to protect this information from unauthorized access or theft.

2.   Preventing Unauthorized Access: ELV systems can be vulnerable to hacking or unauthorized access, allowing attackers to control or disrupt building functions. Cybersecurity measures, such as firewalls, access control systems, and encryption, are necessary to prevent unauthorized access.

3.   Maintaining Building Functionality: A breach of an ELV system can result in the disruption of critical building functions, such as heating, cooling, lighting, and security systems. Cybersecurity measures are necessary to maintain the functionality of these systems and protect against disruptions.

4.   Compliance with Regulations: Many countries have regulations and standards for cybersecurity in buildings, such as the European Union's General Data Protection Regulation (GDPR) and the United States Federal Information Processing Standard (FIPS). ELV systems must comply with these regulations to protect sensitive information and the security of building functions.

System integrator role in SSA Business

System integrator role in SSA Business

Yam, you know SSA is stands for Security Safety Automation (SSA Integrate). A security systems integrator by definition specializes in bringing together subsystems into a whole and ensuring that those subsystems function together. When the goal is physical security, those subsystems might be Video surveillance, Access control, Intrusion, FDA or Emergency notification, BAS, computer networks and more. Some security suppliers have established business simply on the procurement and installation of systems predefined by others. More fully developed are considered ‘design-build’ integrators. However the most capable security integrator is a full service provider capable of supporting your operations in every phase of the security system lifecycle:

1.   Security risk or needs assessments,

2.   System engineering and design for the major technologies,

3.   Broad access to the leading product lines,

4.   Custom engineering when required,

5.   Alternate investment options,

6.   Procurement, staging, installation, commissioning and training,

7.   Full lifecycle service and maintenance,

8.   System functional and technology upgrades.

A client who selects an integrator fully capable in all the above can then take advantage of his unique perspective on what are the key ingredients for successful development of a physical security program that is supportive of a healthy enterprise.

Working with a full service security provider also reinforces quality. Consider why this is so. If, for instance, the integrator offers long term service and maintenance for the system he installs, then both the service provider and the customer are motivated that the design should be solid and the installation of high quality. And if the integrator can offer attractive long term financing, even operational leases, then he again has a further stake in the caliber of the security provided.

System integration is defined in engineering as the process of bringing together the component sub-systems into one system (an aggregation of subsystems cooperating so that the system is able to deliver the overarching functionality) and ensuring that the subsystems function together as a system, and in information technology as the process of linking together different computing systems and software applications physically or functionally, to act as a coordinated whole.

System Integrators in the automation industry typically provide the product and application experience in implementing complex automation solutions. Often, System Integrators are aligned with automation vendors, joining their various System Integrator programs for access to development products, resources and technical support. System integrators are tightly linked to their accounts and often are viewed as the engineering departments for small manufacturers, handling their automation system installation, commissioning and long term maintenance.

Are there tangible ways that we see interoperability trending in the industry?

There is certainly movement toward standard-compliant products but it is slow. I attribute this mainly due to engineers reusing portions of old or outdated specs along with their lack of knowledge of the current product offerings. IP cameras will help move the standards along since more and more clients are aware of megapixel technology and it forces the engineers to become more current.

Where do you see underserved or untapped opportunities for security systems integrators to provide integration and automation expertise?

Video and access technology have the potential to be integrated well beyond the traditional Big Brother stereotype applications. One example is warehouse distribution and processing applications where repetitive tasks performed incorrectly can slow production or cause injuries. Video analytics could be modified to monitor physical movement and monitor improper technique that could lead to injuries.

These videos could initiate notifications to HR and management staff to alert them to potential problems before they occur. Access to machines and forklifts could be controlled through HR records. Integrating the access system to training and safety certifications could help reduce unqualified employees from accessing and enabling critical operational systems. Security could monitor the traditional video footage, HR could assemble incident reports tagged with the video and management could build and expand training programs with real world examples.

Another area of potential growth is the smart building. A fully integrated structure including security, lighting, HVAC and building controls that provides a return on investment along with the ability to remotely manage a site.

How can a locally-based or small regional company have successes in enterprise-level organizations?

Local companies can have a distinct advantage over the national integrators. First, the small or regional company must be technically advanced and focused on cutting-edge technology so they can provide a value to an enterprise-level client. They must also network with similar dealers with related product lines so they can establish an installation network throughout North America or the regions they are required to service. They can also become an agent for the enterprise client and coordinate all installations and manage that system for that client. Compare that level of service to the big integrators. Yes, they have a handful of talented individuals that truly get the big picture and these men and women travel the country and the world implementing systems. But once the job is completed, they’re off to the next one and you may never see them again.

How can smaller integrators differentiate to better compete?

A commitment to service is the local integrators greatest strength. Through continuing education of its technical staff and building working relationships with clients, a local integrator can react quickly and see the big picture of their customers’ needs and requests. As the IT department begins to dominate the physical security industry the local integrator can help be a bridge between the security professionals and the sometimes frustrating “smartest man in the room” syndrome of the IT staff . Most integrators have a great respect for the current and former local and national law enforcement professionals we work with every day. Their knowledge of where and why a camera is placed and how to implement the concentric rings of security, lighting control and placement is invaluable. The human element of security beyond pure technology is something that some IT professionals do not always grasp. Integrators can successful bridging that gap when they strive to clearly communicate with both departments.

What is the Solution Development Process With a Full Service Systems Integrator?

Risk Assessment. Your integrator should be able to assist or guide you in this first step toward development of a security solution. The industry standard for this is the ASIS 7-step general security risk assessment guideline. The guideline defines a process which starts with identification of assets and risk events and ends with a solution cost benefit analysis. Properly done the end product is not only the security you want and need but a documented rationale for the investment.

Financial Options. Similar to many internal enterprise processes the best electronic security solution is sometimes planned to be phased-in over time to give the client the best possible security function progressively. Nonetheless a full service integrator enables you to tailor acquisition of enhanced security in a manner which meets your needs. As an example, reasonably priced capital leases can push the cash flow impact of security into outer years. Due to current accelerated tax depreciation in effect these leases can in some instances reduce the net cost below that of an outright purchase. If a full service integrator has the internal resources – service fleet, repair department, stocked inventory, etc. – to maintain their installed systems they may also offer and administer operational lease programs to the security solutions they provide. These leases differ from capital leases in that ownership of the physical security equipment is retained by the service provider yet the site installation and its sustained operability is available as a monthly service fee.

Design. The functional design should clearly define for the end user the extent of the solution’s protection. It may involve multiple technologies for the most effective solution. Minimizing the burden placed on general staff to maintain security and respond to emergencies should typically be a demonstrable objective.

Value driven component selection may require a number of different supplier sources. Exterior components will be weatherproof, interior components will be vandal and wear resistant as needed. System operation will be well protected from the dangers of tampering, surges, electrical strikes, etc. as well as single points of failure if possible. A good design will not dead-end the customer but position the delivered security solution for adaptation to meet anticipated future needs. Good designs may even enhance as well as protect enterprise and site operations.

Installation & Commissioning. The installation should conform to and even exceed state and federal regulations and guidelines and be performed by licensed personnel as required. The installation should be safe for all onsite, reflect excellent workmanship and conduct should be courteous and respectful to all involved. System configuration should be performed by individuals with good system knowledge. The end user training should be complete enough to address at least typical daily tasks and provide them the resources they need to reinforce the training and administer further if required. This is most likely provided by a resource positioned to be a partner in meeting your security needs.

System Maintenance and Service. The overarching goal is to maintain the operability of your security solution with the same effectiveness experienced as it was commissioned. But electronics degrade and fail and sites often continuously require system tweaks as they grow. A good service program will make available to you certified service personnel as well as standard and emergency response times you can depend on. The best providers will often maintain stock for repair and loan and even have in house bench repair capability for rapid, cost effective turn around. And if you have outgrown your security systems or they are generally showing their age a good provider can offer mid-life upgrades and/or ‘system refreshes’ which progressively secure your operations and people.

Enterprise Security is Not A Commodity.

Why is enterprise physical electronic security more than just a commodity to be procured? Because the security risks are multiple, varied and changing. Some which occur infrequently are the most potentially damaging. An outside perspective developed from meeting a variety of client needs can help prioritize. The current solution state of the art is technical, multidisciplinary and rapidly evolving. There is not a consumer protected design-bid-build process which guarantees success. Only a subset of security industry service providers are equipped and positioned to reliably assist you from needs development through to system maintenance.

Trust on your selective System Integrator or Solution Service Provider.
