Form C alarm contacts and shutdown input
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.
