System alarm signaling applications
What is system alarm signaling?
In system alarm signaling applications, all sounder bases sound when any alarm signal-
initiating device is activated. Signal synchronization is required because alarm signals are not
limited to the same notification zone.
The sounder 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.
• The in-suite signal silence timer expires, if programmed. See “What is in-suite signal
silence?” on page 39 and “Programming in-suite signal silence” on page 88.
Typical wiring for system alarm signaling applications
The figure below shows the typical wiring for synchronized system alarm signaling.
A 24 VDC riser is required to supply power to the sounder bases regardless of riser polarity.
Typically, the 24 VDC riser that supplies power to the sounder bases is supervised using an
