Integrating access control and fire detection

Integrating Access Control and Fire Detection

Most fire jurisdictions require that all doors are automatically unlocked during a fire alarm emergency to ensure a fast exit for those inside the building and a fast entry for the firefighters to do their job. This means the door locking methods (typically electric strikes or electro-magnetic locks)—that are powered and controlled by an Access Control Unit (ACU)—must be kept unlocked during a fire alarm emergency. Fire relay is key product to execute this operation.

What is a fire relay or Output Module?

A output module or control module or fire relay is a switch that sits between the fire system control panel and the power source to the door locking methods. While there are different types of fire relays and different ways to configure them, the job of a fire relay is simple: when there’s a fire alarm, the fire relay unlocks the selected doors.

In an access control system, the fire relay is typically installed inside or near the ACU, and connects the ACU to the fire alarm control panel—as shown in this diagram. Any brand Access Control System can be integrate with Fire, some brand have dedicated port on controller, someone not. You need to verify before getting order. Below arrangement we have test in our experience centre.

Installing a fire relay can be expensive. Follow these tips to get the best pricing.

Lack of a fire relay is one of the most common and expensive surprises we see during customer site surveys. If you’re working with an existing building fire system and it doesn’t already provide a fire relay, you’ll need to get a quote from your building’s fire system provider to install one. 

Unfortunately, the cost of installing a new fire relay can vary significantly. We’ve seen fire relay quotes ranging from Rs. 4000 to Rs. 8000, but there are ways to negotiate for the best pricing. It’s best to include a fire relay as part of your lease agreement with your building management company. If that’s not an option, ask them to negotiate for a fire relay with the building fire system provider on your behalf. Your building management company will likely get better pricing.

If you are building out a new space, you can make a fire relay a part of the general contractor bid so it’s included in the fire alarm system design. Similar to the building management company, your general contractor who is in a position to give repeat business to the fire system provider is more likely to obtain better pricing. Before ordering verify contractor confidence and related document.

Each every manufacture has this module or relay to operate 3rd party equipment Like: Access Control, PA system, Fire Damper, Smoke Damper, AHU etc. If you have Edwards Fire Panel, then only Edwards’s module will be work with proper programming same as Notifier, ESSER, Autronica, GST, Gent any addressable fire brand. If you are not confirm lets contacts us we will guide you free of cost.

The control outputs from a fire alarm control unit can also be sent out on a signaling line circuit (SLC) to an addressable output module, which can open or close a contact based on information sent from the fire alarm control unit on the SLC to the COMM terminals. This is beneficial because multiple output modules can be controlled by the same SLC, which can control each module separately. For example, all output modules controlling all of the door hold opens in a building could be on the same SLC, but based on the specific input to the control unit, only specific doors can be closed. If all of these modules were on the same control circuit, the control unit would only be able to close all the doors.

Guidelines for Schools when Reopen post COVID-19 Lockdown

Guidelines for Schools when Reopen post COVID-19 Lockdown

Worldwide closure of Educational Institutions has impacted over 95% of the Worlds Students population with 1.5 billion learners’ unable to attend College and Schools. Indian Education System is the World’s largest with 1000+ Universities, 41,000 Colleges, 3,10,000 Schools with closely 320 million Students population. The govt will take a decision on reopening of schools and colleges on after reviewing the coronavirus situation in the country. They are our biggest treasure. Safety of students and teachers is of utmost importance to the government and his ministry is prepared to ensure there is no academic loss to students if schools and colleges needed to remain shut beyond April. The Indian Institutes of Technology (IITs) and Indian Institutes of Information Technology (IIITs) will not increase the tuition fee for any course for academic year 2020-21. IIT Kharagpur has created an online forum to help stranded foreign students at the institute share their problems faced during the nationwide lockdown imposed to contain the spread of novel coronavirus. IIM Calcutta has pushed its opening date to July. The institute’s director Anju Seth said that they would focus more on blended learning programmed, and would extend this to more geographies. UGC panel recommends academic session in varsities from Sept, online exams wherever possible. UNODC launches series of online dialogues with students & educators in India on COVID-19. Tripura Education minister Ratan Lal Nath on Sunday said all students of Class 1 to 9 and 11 have been promoted to the next class and virtual classes started for state school students in view of the coronavirus pandemic. Maximum News channel start online classes for each subject & each chaperwise, like ABP Ananda in Bengali. So every corner of education sector are going to online learning due to COVID-19. Now we need to know some facts about COVID-19. Today due to COVID-19 situation all our students are sitting at home and no hope of reopening of campuses before September 2020 and most of these students from long days unable to move out include not able to meet their friends and play.

What is COVID-19
COVID-19 is a disease caused by a new strain of coronavirus. ‘CO’ stands for corona, ‘VI’ for virus, and ‘D’ for disease. Formerly, this disease was referred to as ‘2019 novel coronavirus’ or ‘2019-nCoV.

The COVID-19 virus is a new virus linked to the same family of viruses as Severe Acute Respiratory Syndrome (SARS) and some types of common cold.


What are the symptoms of COVID-19?
Symptoms can include fever, cough and shortness of breath. In more severe cases, infection can cause pneumonia or breathing difficulties. More rarely, the disease can be fatal. These symptoms are similar to the flu (influenza) or the common cold, which are a lot more common than COVID-19. This is why testing is required to confirm if someone has COVID-19.

How does COVID-19 spread?
The virus is transmitted through direct contact with respiratory droplets of an infected person (generated through coughing and sneezing). Individuals can also be infected from and touching surfaces contaminated with the virus and touching their face (e.g., eyes, nose, mouth). The COVID-19 virus may survive on surfaces for several hours, but simple disinfectants can kill it.
The outbreak of coronavirus disease (COVID-19) has been declared a Public Health Emergency of International Concern (PHEIC) and the virus has now spread to many countries and territories.

The protection of children and educational facilities is particularly important. Precautions are necessary to prevent the potential spread of COVID-19 in school settings; however, care must also be taken to avoid stigmatizing students and staff who may have been exposed to the virus. It is important to remember that COVID-19 does not differentiate between borders, ethnicities, disability status, age or gender. Education settings should continue to be welcoming, respectful, inclusive, and supportive environments to all. Measures taken by schools can prevent the entry and spread of COVID-19 by students and staff who may have been exposed to the virus, while minimizing disruption and protecting students and staff from discrimination.

Key Messages & Actions for school administrators, teachers & Staff
Following basic principles can help keep students, teachers, and staff safe at school
·        sick students, teachers and other staff should not come to school.
·        Schools should enforce regular hand washing with safe water and soap, alcohol rub/hand sanitizer or chlorine solution and, at a minimum, daily disinfection and cleaning of school surfaces.
·        Schools should promote social distancing, only two students can come. Seating arrangement also be spread.
·        Schools should provide water, sanitation and waste management facilities and follow environmental cleaning and decontamination procedures.
·      Set Class room or teachers room temperature should under 24 DegC to 30 DegC. Relative humidity within 40% - 70%.

Disinfect school buildings
Clean and disinfect school buildings, classrooms and especially water and sanitation facilities at least once a day, particularly surfaces that are touched by many people (Chair-table, elevator, railings, lunch tables, sports equipment, door and window handles, toys, entrance electronic gate, teaching and learning aids etc) or restricted area (Lab equipment, AC, DVR/NVR, Amplifier, any type controller, Fire Panel, Pump House, Hose, Fire Extinguisher, Reader etc)  through Hydrogen Peroxide (H2O2). This sanitizer not applicable for Human / students / teachers skin. Primarily as a cleaning and disinfecting agent.
SANITIZING TUNNELS are disinfecting passageways for human use if sprays are non-flammable & non-toxic Super oxidized water Hypochlorous acid (HOCL). If purchase from vendor, vendor should share Lab test report & national or international certificate.
Verify Electrical System
Carry out the visual inspections of the distribution boards, switch boards. This is to ensure that during lock down insects have not got trapped in the electrical apparatus. If possible, get the earth values check of the earth pits.
Ensure that all stand by equipment’s are tested for the operations, such as DG sets. 16. Ensure to have those equipment’s in auto mode, if they were kept in auto mode prior to the lock down.
Lift operator should strictly use gloves and mask during duty hours.
Verify CCTV System
CCTV surveillance is now an integral part of the school, collage across the world. Visual inspection of all the components for any kind of damage or loose connections, which might have happened during the lockdown period.
Verify CCTV video footage of each camera and all the recorders (DVR/NVR/Servers etc.) for last 60days. Must be implement thermal image scanning body temperature camera. It can be handheld / tripod standing type.
Checked PA System
Student Announcement or class bell system is integral part of the school, collage across the world. Visual inspection of all the components for any kind of damage or loose connections, which might have happened during the lockdown period along with proper functionality of all the speakers through announcement.

Verify Fire Detection & Protection System
Visual inspection of all the components for any kind of damage or loose connections, which might have happened during the lockdown period alongwith check any fault indication on panel.
Test Detection system through fauls smoke (using aerosol) & Pulling MCP and chk notification signal, other hand test fire Electrically Driven Main (Hydrant / Sprinkler/ Jockey) pump start value stop value, Diesel Driven Pumps etc. Checked all fire Extinguisher are in correct place and healthy.
Monitor school attendance
Strictly avoid attendance thru fingerprint based biometric machines instead use face/eye scanning biometric machines or wave-based machine. Visual inspection of all the components for any kind of damage or loose connections, which might have happened during the lockdown period Implement school absenteeism monitoring systems to track student and staff absence and compare against usual absenteeism patterns at the school. If Body temp screening camera not installed then implement thermal Face scanning Solution can be integrate with attendance solution.

Adapt school policies where appropriate
Develop flexible attendance and sick leave policies that encourage students and staff to stay home when sick or when caring for sick family members.

Establish procedures if students or staff become unwell
Update emergency contact lists. Ensure a procedure for separating sick students and staff from those who are well – without creating stigma – and a process for informing parents/caregivers, and consulting with health care providers/health authorities wherever possible.

Remember that symptoms of COVID-19 such as cough or fever can be similar to those of the flu, or the common cold, which are a lot more common.
Instead of keeping children out of school, teach them good hand and respiratory hygiene practices for school and elsewhere, like frequent handwashing (see below), covering a cough or sneeze with a flexed elbow or tissue, then throwing away the tissue into a closed bin, and not touching their eyes, mouths or noses if they haven’t properly washed their hands.

Checklist for Parents & Community Members
·        Monitor your child’s health and keep them home from school if they are ill.
·        Wash your hands with soap and safe water frequently. If soap and water are not readily available, use an alcohol-based hand sanitizer with at least 60% alcohol. Always wash hands with soap and water, if hands are visibly dirty.
·        Ensure that safe drinking water is available and toilets or latrines are clean and available at home.
·        Cough and sneeze into a tissue or your elbow and avoid touching your face, eyes, mouth, nose.
·        Encourage your children to ask questions and express their feelings with you and their teachers.
·        Coordinate with the school to receive information and ask how you can support school safety efforts (though parent-teacher committees, etc.)
Key Messages & Actions for Students & Children
Children and young people should understand basic, age-appropriate information about coronavirus disease (COVID-19), including its symptoms, complications, how it is transmitted and how to prevent transmission.

Checklist for Students & Children
