Most of the office and building operators agree that fire alarm devices are necessary. Its system can alert the occupants to an emergency so that they can take action to protect themselves and others.
What is Fire Alarm
Fire alarms are devices that make a loud, high-pitched sound to warn people that there is a fire. Furthermore, its system provides zonal coverage to commercial and residential buildings. Their warning signal is either a loud siren or flashing light. Also, it can include both.
Fire alarms are often unnoticed until there is an emergency, but they are part of our everyday routine. They are found mainly in public buildings, factories, stores, and offices. Whenever the alarm is triggered, a signal will send to warn people in the building.
Types of Fire Alarm Detectors
Detection devices are at the core of every fire alarm system. There are different types, from manually operated break glass units to intelligent smoke detectors.
- Manual Call Points
The Manual Call Point is also known as the Break Glass Call Point. It is a device that enables building personnel to raise the alarm by breaking the glass. Then, this will trigger the alarm.
- Multi-Sensor Detectors
The Multi-Sensor detectors are from optical and heat sensor inputs designed to be sensitive to a wide range of fires.
- Carbon Monoxide Detectors
Carbon monoxide detectors are also known as CO Fire Detectors, which indicate an outburst of fire by sensing carbon monoxide in the air. However, they can’t detect smoke or any other combustion material rather than carbon monoxide.
- Smoke Detectors
- Ionization Smoke Detector
The Ionization Smoke detector consists of two chambers. First is used as a reference to recoup for changes in pressure, humidity, and temperature. The second one ionizes the air passing through where current flows.
- Light Scattering Smoke Detector
It operates on the Tyndall effect. Therefore, a Light Scattering smoke detector detects the smoke by sensing the light reflected by smoke particles.
- Light Obscuring Smoke Detector
Smoke interferes with a light beam between photocell and light source. Therefore, the detector’s circuit activates the alarm when the smoke particles are dense enough to reflect light.
- Heat Detectors
Heat detectors detect any significant increase in temperature, which may indicate a fire outbreak.
Types of Fire Alarm Systems
- Conventional Fire Alarm Systems
The detectors and call points are set out in zones to locate the cause of the alarm.
- Addressable Fire Alarm Systems
The detection principle is the same as the Conventional. However, an Addressable fire alarm system can determine exactly which call point or detector has initiated the alarm.
- Intelligent Fire Alarm Systems
This system can provide the exact location of the fire.
- Wireless Fire Alarm Systems
This system is license-free radio communication interconnecting the devices and the sensors.
Have Your Home Safe and Secure
One of the most important things to make your home safe is having a fire alarm system. You will become aware as soon as possible in case a fire occurs. Having this well-maintained system is the first step to protect lives and property. Call the experts!
