    Fire alarm system plays an important part of the fire and life safety of building and its occupants. Fire alarm system main function is to detect a fire at a sufficiently early stage so that the people who are at risk can made safely either by escaping as fast as possible or extinguishing the fire that can also reduce or prevent the property damage. Therefore, a reliability and functionality of fire alarm system as a whole is very important. 

    The following are the different types of the Fire Alarm System:

    1. Conventional fire alarm system

    a. Conventional fire alarm system uses physical cabling to connect several detectors and call points. Conventional fire alarm system has no way to identify immediately the exact location of the fire, but can be arranged in “Zones” to easily identify the location of the cause of the alarm. Its devices are cheaper but will consume more cable wires compare to addressable, since each device will be connected to the control panel by its own cable wire. This system are mainly used specially in smaller property.

    2. Addressable fire alarm system

    a. Addressable fire alarm system has the same detection principle, except that each detector can be given a set address that can help to identify the exact location of the detector that initiated the alarm, that can be seen in the fire alarm control panel. Addressable fire alarm system saves a lot of wire compare to conventional system, since the devices can share one cable wires up to the last device. Both ends of the wire is loop connected to the fire alarm control panel. This system are very suitable for large and high buildings, since they are able to pinpoint exactly which devices are triggering the alarm.

    3. Wireless fire alarm system

    a. Wireless fire alarm system, is hassle-free to install compare to conventional and addressable since it does not use any conduit and cable wires. However, even though you saved a lot of money in material and labor cost, the hardware and programming are higher than the wired systems. The devices are battery powered and can be placed anywhere and can be easily relocate if needed.

    Fire Alarm System Components 

    The main component of fire alarm system are the following:
    1. Fire Alarm Control Panel
    Fire Alarm Control Panel is the brain or central hub of a fire alarm system. It displays the location and status of the alarm devices, and it gives precise location of the device that cause the alarm.

    2. Fire Alarm Initiating Devices
    Fire Alarm Initiating Devices are the devices that detects signs of fire and triggers the alarm. They are connected to the fire alarm system control panel. Initiating devices includes smoke detectors, heat detectors, flame detectors, manual pull station and fire sprinkler water flow switch.

    3. Fire Notification Devices
    Fire Notification Devices are the audible and visual devices in fire alarm system, it includes fire alarm horn, speaker and bell. Its main function is to alert people at risk in the event of a fire, that is why it is considered as the most important components of fire alarm system.

    4. Primary Power Supply
    Primary power supply is typically supplied by the local utility, and also from generators that are located in remote areas wherein the electrical grid is not available. 
    5. Backup Power Supply
    Backup power supply commonly supplied by batteries and stored internally or adjacent to main fire alarm control panel or can be also from generator. It must also provide a 24 hours of power supply to control panel in case of power shortage.

    How Fire Alarm System Works? 

    In an event of a fire emergency, the fire alarm system main role is to detect fire and to alert people at risk inside the building and emergency response team to control the situation as fast as possible. Fire alarm system key functions is to detect (by the use of smoke detectors, heat detectors, flame detectors, etc.) , alert (by the use alarm horn, speaker, and bell), and monitor (control panel). 

    Fire Alarm System Maintenance 

    A functioning and well-maintained fire alarm devices can help reduce injuries, save lives and properties. The fire safety systems inspection, routine maintenance, and testing will help one in keeping in compliance with the local/state fire inspectors and also their insurance carrier. To keep the best condition of the fire alarm devices, it is advisable to keep a scheduled maintenance and check the following: 
    1. Checking of physical appearance of the fire alarm devices
    2. Smoke Detectors should be cleaned & tested for sensitivity levels (addressable type)
    3. Fire alarm control panel should be tested for all alarm, trouble, supervisory, reset & silence function
    4. Checking of the devices power supply
    5. Checking/ replacement of batteries
    6. Checking/ removal of any obstruction on the devices that may cause false alarm or malfunctioning
    7. Checking if the alarm is audible
    8. Devices must be replaced when exceeded 10 years from the manufactured date

  • The Standalone LPG Gas Detector detector is designed for single station using. Small and compact, the design and color makes it ideal for use in the home, small commercial properties and recreational vehicles. It is intended to detect CH4 gas.The gas detector can be mounted high (for CH4 gas). It is equipped with a sturdy mounting bracket for quick, easy and safe 
    Standalone LPG Gas Detector Features
    • Easy to install, mounting bracket included.
    • Loud 85 dB alarm and LED warning light.
    • High quality durable sensor.
    • Self diagnostic function by MCU intelligent software.
    • Excellent reliability & High stability.
    • Ideal for all kitchens.
    Standalone LPG Gas Detector Installation Instructions
    The Gas detector is intended to detect  CH4 gas. It is intended for installation in the home, small commercial properties, and recreational vehicles . 
    Installation shall only be undertaken by technicians holding a certificate issued by an authorized distributor.
    For detecting CH4 gas (lighter than air), the detector should be installed within 30 centimeters below the ceiling and 50 cms above the oven and the maximum distance away from the furnace or gas appliances is 4 meters.
    The detector should not be located close to any obstacles preventing natural air circulation. It should also not be located in a draft or close to a cooker (cooking smells and other fumes can have a bad influence on gas detection).
    Standalone LPG Gas Detector Operation And Testing
    Check and test the gas detector after installation.It should be tested weekly and check after re-occupation following a holiday.

    How To Test And Check LPG Gas Detector?
    Power on :The green work light starts to flicker and  the warm-up time is 2 minutes .During this process, only the button responds,and other tests do not can work normally after the warm-up is completed,and the green work light is always on before the test can be performed.
    Normal: When the device is in a normal state, the green      light on the power supply is on, and the other lights are off
    Fault:  When the sensor is in a fault state, the yellow LED of the sensor flashes slowly. After troubleshooting, the device will return to normal
    Alarm: When the detected gas leakage reaches the alarm level, the red alarm light will be on and the buzzer will sound. Usually the default models are relay and pulse voltage output.
    Test: Under normal circumstances, press the test button, the unit should make a sound, the three LED indicators will light up once, the buzzer will beep twice, and there will be no signal output. In order to ensure the normal operation of the gas detector, you should test it once a week
    Mute: The local mute can not be used in the alarm state, but the host can only be used to mute the sound remotely.
    Reset: Local reset cannot be used in the alarm state, but the host can only be used to reset all remotely, there is no output, the alarm light is off, and it enters the preheating state
    Remote test: the red light flashes when the host is testing
    Remote mute: when the local alarm, the yellow fault light flashes quickly when the host mutes the sound remotely
