Automatic fire alarm (APS) (Fire alarm installation)

The APS includes subsystems:

• Fire alarm.
• Evacuation management.
• Water, foam or gas fire extinguishing.
• Control and access control (ACS)
• Smoke removal and ventilation control.

The task of MTA:

• Detection of any signs of ignition (gas, smoke or open fire) at the earliest stages.
  
• Transfer of an alarm signal to the console or guard post.
  
• Informing staff about the fire.
  
•  Management of evacuation.
  
• Automatic unlocking of all turnstiles, gates, doors for free evacuation.
  
• Automatic return of elevators to the 1st floor and the opening of their doors.
• Automatic activation of smoke and fire extinguishing systems.

The principle of the APS: Having detected signs of ignition at the earliest stage, APS:

• Includes an alarm system (voice or light and sound) and evacuation control.
• Simultaneously transmits control signals to all other subsystems: access control, smoke removal, elevator control, fire extinguishing and forced ventilation systems.
