ANALOG SENSOR
*
Remote common alarm indication, remote pilot indication, remote common reset, common shutdown and common visual indication.
*
Common fault indication (when green pilot LED is extinguished) cannot be achieved on the FAD-325 Duct Units. Individual Remote
Pilot LED's must be installed to monitor detector head or power source removal for each unit.
*
In the event of an alarm, the detector head and duct unit alarm (Red) LED's will be illuminated. All remaining duct unit alarm LED's will
not be illuminated. All remote alarm LED's fitted to the duct units will be illuminated when any of the units go into alarm. Only the duct
unit in alarm will permit resetting of the system from the built in test/reset switch on that particular duct unit.
*
A common Remote reset switch will reset all detectors.
Common functions include one or all of the following:
