RELAY MODES OF OPERATION 

 

Auto Reset (Maintained Momentary) 

When signal is received from an authorized transmitter, the relay will energize. The relay will maintain 
the energized state as long as the transmitter is sending the signal. The relay de-energizes when the 
transmitted signal stops. 

Toggle Reset (Toggle Latch) 

When a signal is received from an authorized transmitter, the relay will energize and latch. The relay 
stays energized until the same signal is received again, at which time it unlatches and de-energizes. 

Latching Reset (True Latch

 

When a signal is received from an authorized transmitter, the relay will energize and latch. The relay 
stays energized until a different signal is received from the transmitter, at which time it unlatches and 
de-energizes. i.e. 

– Transmission from Input 1 of authorized transmitter energizes and latches relay 1. 

Transmission from Input 2 of an authorized transmitter de-energizes relay 1.
