APC ACRC103, ACRC100 manual Form C alarm contacts and shutdown input, Leak detector port

Form C alarm contacts and shutdown input

Remote switch using internal power (24 Vdc shown)

Field-supplied voltage (12/24 Vdc or Vac)

A relay internal to the user interface is typically controlled by a user-defined alarm (malfunctioning fans, for example). Before an alarm is detected, the voltage on the COM terminal is routed to the NC terminal. When the alarm is activated, the relay is energized, causing the voltage on the COM terminal to be routed to the NO terminal. The NO and NC terminals may be connected to remote indicator lights, a warning buzzer, or another device to alert an operator to the presence of an alarm condition.

A remote disconnect switch may be connected to the shutdown inputs.

Leak detector port

Rope water detector (AP9325). Up to four optional rope water detectors can be installed in series. The rope water detector connects to the RJ-45 leak detector port located at the top of the interface box.

See the “Rope Water Detector” installation sheet

(supplied with the kit) for installation and setup information.
