a FX-NAC Analog NAC Module.
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 38 and “Programming in-suite signal silence” on page 85.
Typical wiring for system alarm signaling applications
The figure below shows the typical wiring for synchronized system alarm signaling. The
24 VDC riser that supplies power to the sounder bases is supervised using a FX-NAC Analog
NAC Module.
