NOTE: The wiring diagram below represents the most common wiring configurations. Please consult your FACP manufacturer for panel-specific wiring configu-
rations and special cases.
Additional Audible Visible devices may be connected to the same power supply or the the NAC output of the Fire Alarm Control Panel (FACP) to provide a syn-
chronized communication of the alarm signal.
NOTE: Wiring shown for System Sensor MDL Series Sync Module. For additional wiring configurations, see your sync module manual.
