Type 3b: – A suffix that designates a Type 4 or a Type 6 system is required instead wherever there is only a single escape route.
Keeping this in consideration, how do fire alarm panels work?
The fire alarm system can be set off automatically by smoke detectors, heat detectors or manually. The optical smoke detector detects smoke by using light sensors (infrared LED). When smoke particles pass thru the chamber of the optical detector, it scatters light that triggers the alarm.
How do you determine fire alarm zone?
Building zones aren't determined by where the wires are run for the fire alarm system; building zones are determined by the building's fire-control/fire-fighting separations and by the building's smoke-control separations.
