Zone alarm signaling application
In zone alarm signaling applications, audible detector bases in the
same notification zone are activated using a CRR module when any
one of their detectors is activated (initiate an alarm event). Signal
synchronization is not required because alarm signals are limited to
the same notification zone.
The audible detector bases, once activated, continue to sound an
alarm signal until:
• Smoke is cleared from the active detectors and the control
panel is reset
• Signal Silence is pressed
• The control panel’s Auto Signal Silence timer expires, if
programmed. This can be from 5 to 30 minutes.
Typically, the 24 VDC riser that supplies power to the audible
detector bases is supervised using an RM1 module. You can also use
a CT1 module and a PAM-1 control relay.
