You may ask yourself, how do fire alarms function, if you’re looking for a fire warning system. Let’s take a look at how fire alarm systems are constructed and what each component does.
The following are the components of a fire alarm:
- These are devices that can detect a large amount of heat or smoke in a room.
- The audio devices: This is the device which makes an alarm sound to alert people of the possible presence of a fire within the building.
- There is a beacon, or it can be a strobe. It is used when the noise is high.
- Fire Alarm Control Panel – This is the central brain of the system. It monitors the devices and makes sure they are working properly. If any detectors go off, it will indicate the exact area or zone depending on the type of system.
- Add-on equipment, such as call points for alarming or interface units that can be used to shut off the gas or open the roof vents. For Fire Alarms Northamptonshire, visit https://firealarmsystems.co.uk
Smoke Detectors
Smoke detectors are available in optical and ionized versions. Smoke detectors that use optical sensors “see” smoke using infrared lights. Light is scattered by smoke particles that enter the sensor. Alarms are triggered by this.
Heat Detectors
Heat sensors monitor environmental temperatures. They will sound an alarm in the event of a sudden rise. Some sensors have the temperature of the room preset. This threshold will cause the alarm to sound, no matter what other parameters are set.
Fire Alarm Control Panel
It’s much easier to understand the fire alarm system now that you’ve seen what it contains. The fire alarm system is activated when the heat or smoke sensor detects abnormally high levels of temperature or smoke. This sounder will alert people in the building to call for the fire brigade, and guide them and other occupants towards an emergency exit.
