- FIRE ALARM SYSTEM:
- A fire alarm system is a network of devices designed to warn people of a potential fire and facilitate safe evacuation from a building. It consists of interconnected components that work together to detect and alert occupants of a fire.
- The main components of a fire alarm system typically include:
- Fire alarm control panel (FACP): This is the brain of the fire alarm system. It receives signals from the fire detectors and initiates the alarm sequence, which includes activating the audible and visual alarms.
- Fire detectors: These are devices that detect the presence of smoke, heat, or carbon monoxide, which are all indicators of a potential fire. There are different types of fire detectors, including smoke detectors, heat detectors, and carbon monoxide detectors.
- Audible and visual alarms: These are devices that alert the occupants of the building to a fire. Audible alarms typically produce a loud, piercing sound, while visual alarms may include strobe lights or flashing LED lights.
- Manual pull stations: These are devices that allow occupants to manually activate the fire alarm system in case of a fire.
- OPERATING PROCEDURE:
- Fire Alarm Main Panel (FAMP) is placed at BMS Room and the repeater panel is located at Security Office near Main Gate to identify fire occurrence in the Manufacturing, Warehouse, QC, QA Department, etc.,
- ISDs, HD, MCPs, are installed in various locations of manufacturing, Warehouse, QC, and QA. MCCs of all blocks and PCC to notify / indicate any Emergency / Fire in the concerned area.
- Controls and Indicators of the main panel are mentioned below.
- Power LED
- Supvr LED
- Test LED
- Alarm Switch/Silence
- CPU Fail LED.
- Reset switch/LED.
- Ground Fault LED.
- Disable LED.
- Drill switch/LED.
- Panel switch/LED.LCD Screen.
- Trouble switch/LED.
- Monitor Switch LED.
- Previous message switch.
- Next message switch.
- Command menu switch.
- Details switch.Enter key.
- Delete/backspace key.
- Numeric keypad.
- Alarm switch/LED.
- In case of any emergency like Fire, Toxic gas release, Leakage / Spillage of Toxic/ Corrosive materials etc., The operation of the MCPs are as follows:
- Break the glass of the MCP (Red Colored Square shaped) with the hammer provided.
- Pull down the MCP (Red colored square shaped).A siren/buzzer will be started and all the sounder in the site as per the zone matrix will be activated. The panel will display the Panel Controller and Detector number with the area text and with MCP area and at the same time public addressing shall be announced a voice message to evacuate the area as emergency is happened.
- On hearing of the Fire Alarm, the area in-charge / incident controller takes control of the situation and starts taking necessary actions to mitigate the emergency / fire.
- Once the problem is identified then the Alarm switch/silence to be pressed as shown in the screen shot-1 on the main or repeater panels whichever is easily available to make the panel silence.
- The security shall inform to all the departments of the incident happened.
- Once the Alarm switch/silence is pressed then the entire siren will be silent.
- The connected MCP or detector shall be opened for making it reset to keep the system in operation.
- Note: Until the reset made successfully then only the PA system will be silent after a 30 Seconds delay.
- The emergency response team members / Site Controller / First aiders / Fire fighters /Ambulance van etc., will rush to the emergency spot/area.
- After knowing the location, the emergency team members will rush to the spot/area of emergency and take necessary actions to mitigate the emergency.
- After mitigation of the emergency, Security / Shift Electrician / ERT member / Safety person will reset by pressing the “SYSTEM RESET” button on FAMP/FARP and MCP.
- RESETTING OF NFLP- MCP:
- Open the Red colored glass box with proper screwdriver.
- Unlock the cover release screw with screwdriver.
- Put the toggle switch in normal position and close the box.
- Refix the MCP and Red colored glass box with proper screwdriver.
- RESETTING OF FIRE-DETECTOR:
- Push the access slot lock on the detector and rotate to unlock it from the base.
- Gently clean the sensor area with a dry cloth and with blower with minimum speed.
- Re-fix the detector to the base to the previous position.
- Press the “Reset switch/LED” key on FAMP/FARP to keep system back to normal condition.
- FUNCTIONING OF BEAM DETECTOR:
- It is four wire conventional reflected beam detector, which is uniquely suited for protecting open areas with high ceilings where other methods of smoke detection are difficult to install and maintain.
- Beam detector consists of a transmitter/receiver unit and a reflector when smoke enters the area between the unit and the reflector.
