The ELK-941 separates the steady or pulsing voltage from a single alarm output and directs this into two (2) different relay outputs. This is ideal for activating a two channel long-range radio or cellular transmitter, a two channel siren, strobe light, or bell from the single alarm outputs found in most alarm control panels. A steady voltage input activates Relay 1 (typical for burglary) while a pulsing voltage input activates Relay 2 (typical for fire). A 3 to 4 second verification delay time occurs before the relays activate. Either relay can be set to ignore the delay time and provide an immediate output for installations requiring a siren or bell test. A separate output is available for triggering a low current sounder or LED during the delay time. An optional jumper configures Relay 2 to pulse in a temporal coded bell pattern which meets ANSI Standard S3.41 for fire signaling. The input trigger can be either positive or negative (pull to ground).
