Increase of BMS cables sale

The global IBMS market is highly fragmented with the presence of several global and local vendors. Global vendors mostly operate as original equipment manufacturers (OEMs), catering to the requirements of the end-user through distributors/dealers or system integrators. Technical knowledge and ability to customize based on end-user requirement by vendors will hold the key to a strong foothold in the market.

Building management system cables also commonly known as BMS cables, intelligent building cables or automation cables are used to automate all of the systems in place within a building or home. Research suggesting the BMS market will reach $19.25 million by 2023; it’s even more of an opportunity for electrical contractors to capitalize.

The global IBMS market will continue to grow at a healthy pace throughout the forecast period. Apart from energy and cost savings, other important drivers are the degree of flexibility provided by open IBMS solutions, the high degree of productivity it provides, and a higher return on investment along with enhanced security. These factors are attractive to many businesses, thus driving the market growth.

An advance Building Management System can control the safety in homes and offices, monitoring doors and windows for alarm systems and detect floods and fires. Equipment and installations are designed for the control, monitoring and optimization of various functions and services provided in a building that includes: heating, ventilation, air-conditioning, lighting, security systems and the operation of electric / electronic applications. 

A shielded cable that is not grounded does not work effectively. Any disruptions in the path can raise the impedance and lower the shielding effectiveness. Firstly make sure you have a cable with sufficient shielding for the application's needs. In moderately noisy environments, a foil alone may provide adequate protection. screened cable (plural screened cables) Wire for the transmission of electricity or electronic signals, protected by an enclosing web of earthed wire mesh to avoid electromagnetic interference from (or to) other signals. Grounding: a point in contact with the ground, a common return in an electric circuit and a arbitrary point of zero voltage potential. It also provides personal safety and protects the equipment. Control the voltages developed on the ground when the earth-phase short circuit returns through a near or distant source. Provide a stable voltage reference to signals and circuits. Minimize Electromagnetic Emission (EMI) effects.

Shielding: The shield must be connected to the signal reference potential of what is being protected. When there are multiple segments keep them connected, ensuring the same reference potential. The shielding is only efficient when it establishes a low impedance path to the ground. A floating shielding does not protect against interference. The use of non-magnetic metals around conductors does not shield against magnetic fields.

The cabling of the industrial communication systems (Modbus RS485) is different in some ways from the cabling used for power cabling and the electrician may experience some difficulties if he is not an expert in Modbus communication networks. A Modbus RS485 connects a Master device to one or more Slave devices. Henceforth, we shall consider Slave devices to be measuring instruments with serial communication, even if the cabling is similar for all Modbus devices.

Cable Selection

You should consider the following:

·         How many conductors do you need?

A minimum of three conductors, but the shield may be used as the common conductor, so shielded two conductor cable may be used. If you do not use shielded cable, then at least three conductors are required. Some RS-485 devices do not use a common connection, but we recommend always connecting common for reliable performance and to avoid damage due to surges.

·         What wire gauge do you need?

·         For unterminated networks, the current will generally be less than 10 mA and any gauge should work; we recommend #24 AWG to 18 AWG.

·         For terminated networks, the current can be 60 mA or higher, so heavier gauge wire may be needed for very long runs.

·         We recommend #22 to #20 AWG for runs up to 1000 ft. (~300 m).

·         We recommend #20 to #16 AWG for runs up to 4000 ft.(~1200 m).

·         What should the cable impedance and capacitance be?

Cables suitable for use in an RS-485 network should have an impedance of between 100 and 130 ohms, a capacitance between conductors of less than 30 pF per foot (100 pF per meter), and a capacitance between conductors and shield less than 60 pF per foot (200 pF per meter).

·         Do you need shielding?

Because RS-485 is differential, it is less susceptible to interference, so shielding is not always necessary. However, we recommend shielding for long runs and if there is electrically noisy equipment nearby like variable speed drives. If you use shielded cable, connect the shield to earth ground at one end (generally the PC or RS-485 master).

·         Do you need twisted wires?

Yes, especially for non-shielded cable.

·         What voltage rating do you need?

We recommend wire or cable rated for the highest voltage present. So if you are monitoring a 120/208 Vac panel, you should use 300 V rated cable. If you are monitoring a 480Y/277 volt circuit, use 600 V rated cable. If you have the WattNode in a separate enclosure and there is no way the mains wires can contact the Modbus output cable, then you could safely use lower voltage rated cable, such as 150 V or lower. Long runs of 300 V or 600 V rated cable may be expensive, so it may be more economical to use lower voltage rated cable and use a protective jacket in the regions where the cable is in the vicinity of dangerous voltages.

·         Can you run the RS-485 network cable adjacent to or in the same conduit with mains wires?

We strongly recommend against this. There may be interference from the high voltages and currents present on the mains wires, and if there is any insulation fault, arcing, etc. on the mains wires, it could put dangerous voltages on the low-voltage RS-485 network cable.

Most modern buildings now incorporate some form of BMS, focusing primarily on energy efficiency and saving costs. Whether that’s through proximity sensor lighting, climate control, door entry or security, they all work to achieve the same goal.

Efficient lighting control in a BMS system is just one way of reducing energy and saving costs for building owners. Using BMS, lighting can be automatically adjusted, depending on natural light detected or amount of people in the building. These cables are available in Low Smoke Halogen Free (LSHF), meaning they give off minimal smoke and toxic fumes. This is ideal for installation in public buildings such as schools, hospitals or airports where evacuation may be difficult in the event of a fire.

Unlike what happens in many energy distribution systems, the manner in which the devices are connected in parallel is important. The RS-485 system used for Modbus communication provides a main cable (Bus or backbone), to which all the devices have to be connected with branches (also known as stubs) that are as short as possible. The branches must be no longer than 1200 mtr.

Maximum distance and maximum number of devices. The main cable must be no longer than 700 m! This distance does not include the branches (which must nevertheless be short). The maximum number of devices that can be connected to a main cable is 32, including the Master.

In order to increase the extent of the Modbus network, repeaters can be used; and signal amplifying and regenerating devices provided with two communication ports that transfer to each what they receive from the other.

The cable shield must be earthed only in one point. Normally, this connection is made at one end of the main cable.

In order to avoid signal reflections, a 120 Ohm termination resistance must be fitted on each end of the main cable. The end resistance must be used only at the ends of the main cable. If the total length of the main cable is less than 50 m termination resistances can be avoided at the ends of the main cable.

Fire safety is another major reason why owners may consider installing a BMS system into their building. High performance fire survival cables provide an excellent solution for connecting BMS with fire systems. The data and coaxial ranges are designed to carry on functioning in the event of a fire and provide vital signals to voice alarm, CCTV and allow systems to be shut down in an orderly fashion. Meeting specific fire resistance requirements.

System Integrator tips to win Sales Proposals for New Access Control Systems

Access control provides the ability to control, monitor and restrict the movement of people, assets or vehicles, in, out and round a building or site. It is only a matter of time before you receive the highest compliment from one of your customers when they say: “We need a completely new access control system, and we want you to design and implement it.”

Any security systems integrator (Security Safety Automation Integrate - SSA Integrate) who has ever worked on an “enterprise-level” access control project will tell you it is not just standard access control, only larger. There are a host of requirements, challenges and issues that come with true enterprise access control.

Today’s enterprise-level projects are more complex than ever, with an emphasis on integration with not only other security systems such as video, but also Active Directory, building control and even beyond — in some cases going to PSIM-level integration. Technologies such as mobile credentialing, PoE and convergence have all to greatly impact this space in recent years, requiring more technical expertise than ever before on the part of the security systems integrator. I am always with you, in case of any designing issue / guide is required, just give me a mail – I work for smarter & safer future – Arindam Bhadra.

Now I share some Checklist to win sales proposal for New Access Control Systems. If you approach it methodically, you can reduce error and ensure that your customer gets the exact system they require.

Questions to ask include:

• What is the short-, mid- and long- range vision for the access control system? Is it based on open standards, like 802.11b/g or 802.3af, for the most affordable infrastructure? Is it scalable enough to support possible mergers and acquisitions?

• What type of Access Card / credential(s) will be used? How many are issued? What type of format will be used, and can it support a projected card-holder population? Is it controlled to ensure there are no duplicate IDs?

• What investment has already been made? Is the current system upgradeable? Or completely new.

• What assets does the end-user have, and what value do these assets have in relation to the operation or business? These range from physical assets like computers to patient records, employee records and client data.

Observe the End-User

Essentially, the integrator should be trying to find out about the culture at the end-user’s location. It can range from an open, accommodating environment, to one with strict and limiting access controls. There will always be a conflict between convenience and security — the challenge is to create procedures and rules that balance these disparate goals.

Did you observe the employees holding doors open for each other? If so, how are they able to verify their current employment status? Did they open the door for persons carrying large packages?

If so, did they check their IDs? Did visitors sign in at the reception desk? Did they wear ID badges? Were they escorted by staff members? Did students have a habit of leaving their rooms unsecure? If so, what sort of liabilities fall on school administration if a theft occurs and they knowingly allowed that practice to continue?

Conduct a Site Survey and Security Audit

Walking through a customer’s facilities can be invaluable when developing a comprehensive access control plan. Here are a few things to look for:

• Mechanical Security: If the openings are not mechanically secure, any additional funds spent on electronic access control are wasted. The following must be addressed before moving forward on an advanced access control system: Are the doors, frames, and hinges in good condition? Are they rugged enough for the application and durable enough for the traffic? Are the frames mortar-filled?

> What key system is in use? Is it a patented, high-security type? How often are locks re-cored? How many master keys have been issued? Have any been lost? How easy is it to reproduce the keys?

> Is there accommodation for the handicapped to ensure compliance with the Local Act?

> Are cross-corridor fire doors in place? Do they have magnetic door holders tied to the fire system?

• Identify the Threat: Consider the enduser’s surroundings: Have you noticed any evidence of gang activity? Have you noticed an increase in shuttered businesses?

If so, perhaps an increase in perimeter security is in order, potentially including increased lighting, cameras and gated access.

• Evaluate the Facility(s): This will help you identify product options. How old is the building? Does it have architectural or historical significance? How thick are the walls? Was asbestos used as an insulating material? If so, it may be difficult and costly to install conventional, wired access control devices. Perhaps a WiFi solution will be a good alternative.

• Identify Assets and Value: Many consider assets to be tangible items that can be sold for quick cash. But assets include anything that someone might want to steal or destroy, and vary among end-users. The important thing is to put a price tag on the loss of the asset, plus the cost of lost productivity and potential liability that could result.

Get the Technical Details

For each opening requiring access control, you’ll need the following details to ensure you order the right product for the given application:

• Does the door swing in or out? Is it leftor right-handed?

• What’s the finish of the existing hardware? What’s the lever style? Would the end-user prefer a more modern look?

• How is each door expected to operate? Ensure that an operational narrative is written for each opening that covers the following conditions, and have the customer sign off on it. This should include: normal state; authorized/unauthorized access and egress; monitoring and signaling; and power failure, fire alarm and mechanical operation.

• Determine where to place access control equipment. This could be an IT closets, server rooms, administrators’ offices or under BMS Room. Make sure your staff will have access for installation, and later for service and maintenance. Also, make sure there is enough space on the wall to mount access control panels, interface modules and power supplies.

• Determine network coverage. Are IP drops where you need them? Is there sufficient WiFi coverage where you need it should you opt for WiFi locksets?

Validate the Security Requirements

Different applications and clients have differing security requirements. Verify these needs with the end-user before starting the system design; otherwise, you could be in for a lot of extra work. The following considerations should be factored into an overall access control plan, as they have a direct impact on product selection and system configuration:

• Lockdown: Is lockdown capability needed in the interior or just the exterior — or at all?

• Real Time: Is real-time communications to the access control system a critical requirement? Perhaps it is for perimeter doors, but what about interior doors?

• Monitoring Requirements: How much monitoring does the end-user need? In most cases, a door position switch will suffice; however, some clients want to know that the door is both closed AND secured — these are not necessarily the same thing.

• Audit Trail Requirements: How important is it to know who and when someone

entered a building or room? For code compliance, this feature is always mandatory, such as accessing computer rooms, personnel records and patient records; however, some companies use audit trail reports to validate employee activity.

• High-Security and Classified Areas: For increased security, there are several options. Is multi-factor authentication a requirement, such as card and PIN or even a biometric verification? Should there be a two-man rule?

• Special Considerations: Some areas, require valid access credentials from both sides of the door — keeping the right people in and the wrong people out. This requirement takes different hardware than a typical free-egress lock or exit device.

Determine Business Requirements

Consider the final details that will allow you to complete your system design:

• Aesthetics: Many high-profile building owners use architectural design to make their facilities stand apart. This extends to the interior space as well. So, is a black wall reader the right choice? Or will an elegant lock with integrated card reader and designer lever be a better option?

• Infectious Disease Control: Some locks and doors are available with an anti-microbial finish designed to inhibit the growth of bacteria.

• Turnover: What kind of turnover does the facility experience? Heavy turnover would be difficult to manage with a PDA-programmable offline lock; however, one-card systems program access privileges onto the card, virtually eliminating the need to tour the doors to reprogram them. Of course, online solutions could address this as well.

• Applications: It is inevitable that a variety of applications will converge into a single system. That’s why it is important to select an access control system that can grow by providing application support for parking access, visitor badging, integrated video and other needs as required.

• System Management: It is important to determine who, how and where the enduser will manage the new access control system. For enterprise-class systems, it might mean multiple departments will manage their own people, while a system administrator will maintain and manage the main, centralized system.

• Budget: You ultimately need to know your customer’s budget; however, with all the upfront research, your findings might be beyond their initial scope. This is how long-term planning comes into play so you can develop a priority list over several phases to ensure the end user gets the access control system that fully meets their requirements

Ensure Code Compliance

Several agencies have issued codes and standards over the years to enhance life safety, improve privacy and reduce fraud. They need to be factored into an overall access control plan, and the Health Insurance Portability and Accountability Act (HIPAA). National Building Code of India 2016; Life-Safety (NFPA 101) — Means of Egress; Fire (NFPA 80) — Retro-fitting, Sprinkler Systems; Accessibility (ANSI A117.1) — Operators, Credentials; and Electrical (NEC NFPA 70) — Installation, Wiring, Products. Select products and services that meet the design requirements and comply with current standards, such as EN50133 European Access Control Standards and Electrical wiring regulations.
