Local alarm signaling applications
What is local alarm signaling?
In local alarm signaling applications, an audible detector base (sounder base) automatically
sounds an alarm signal when its detector is activated. All other sounder bases on the same
riser remain silent until their detectors are activated.
The sounder base continues to sound an alarm signal until smoke is cleared from its detector
and the control panel is reset.
Typical wiring for a local alarm signaling application
Typically, the riser that supplies power to the sounder bases is supervised using an RM1
module. You can also use a CT1 module and a PAM-1 relay.
