This product is specifically designed to meet the needs of the fire/intruder alarm industries. The PCB is mounted in a single gang front plate as illustrated.
The main applications are;
Fire Alarm Panel interlinks, remote signaling (dialer’s), Door release control, outdoor lighting control (Fused/Live & Neutral switching), monitored circuit interfacing (bell circuits), general interfacing (Plant shut down ETC) and the single pulse output option is also useful for triggering surveillance systems or start-up computer based systems.
The unit has a wide ranging trigger INPUT voltage (9.5V to 42VDC and 7.5V to 30VAC RMS) and also incorporates a timer (this counteracts fire control panel interlink latchups – enabled by removing the LINK). A series diode is also “built-in” which allows easy connection to fire alarm monitored bell type circuits.
The unit has at its heart a relay which is capable of switching 8A @ 250VAC (2000VA) for 100,000 operations, however it has been fused at 6A to give extreme durability. An LED (RED) is provided to ‘visually indicate’ that the contacts are in the active position (note: not the presence of the I/P trigger voltage but the contacts in the active state IE will show if timer has elapsed).
