Signaling Systems
Provide detection, early warning for evacuation, and fire department notification.
There are six basic types of signaling systems:
- Local System Supervised systems that provide fire alarm signals within a facility and produce the signal at the facility only. Requires someone to notify the fire department. The main purpose is to sound the evacuation signal in building.
- Auxiliary System Basically a local system with connections to transmit an alarm to the fire department.
- Remote Station System Signals transmitted to a remote station via the telephone line. Remote station is usually a fire station attended by trained personal 24 hours a day.
- Central Station Attended 24 hours a day by personal who monitor the system, investigate signals and are responsible for system inspection, maintenance and testing.
- Proprietary Protective Signaling System Has a central station owned by protected property staffed 24 hours a day. Used mostly in large commercial and industrial occupancies.
- Emergency Voice/Alarm Communication System Provides transmission of information and instructions pertaining to a fire emergency to the building occupants, including the Fire Department.
Modern systems may, additionally:
- operate smoke control equipment
- control elevators
- control exit doors
- or trigger special extinguishing systems.
The type of signaling system to be used depends on the needs (life safety/property protection) of each facility or individual property.
