Automatic fire alarm (AFS) is a security system designed for early detection of fire in buildings and structures. It plays an important role in ensuring the safety of people and property, allowing a timely response to a fire.
How does APS work?
The main task of an automatic fire alarm is to detect a fire at the earliest stage of its occurrence. To do this, the system uses various sensors and devices:
- Thermal sensors: detect rapid increases in room temperature, which may indicate a fire.
- Smoke detectors: detect the presence of combustion products or smoke in the air and activate an alarm.
- Optical sensors: use laser and infrared beams to detect changes in the optical density of air caused by smoke.
- Ionization sensors: measure the level of ionization in the air, which changes in the presence of smoke.
When at least one of the sensors detects signs of fire, the alarm system automatically activates the alarm, notifying people in the building and sending a signal to the centralized control panel or the local fire department.
Advantages of automatic fire alarms
- Rapid detection of fire in the early stages, allowing extinguishing measures to be taken before the flame spreads.
- Minimizing the time it takes to evacuate people from a building.
- Timely notification of fire services for a quick response to an incident.
- Increased overall safety and reduced fire damage.
- Can be integrated with other security systems such as fire extinguishing systems and automatic escape doors.
