The ECO1000BREL12NL is a 12 V non-latching relay base for System Sensor ECO1000 conventional detectors. The relay switches when the detector goes into alarm, and the base periodically isolates the detector from the supply to give an automatic reset once the alarm has cleared.
Key features
- Plug-in relay base for System Sensor ECO1000 detector heads
- Works in 2-wire and 4-wire systems
- Normally open and normally closed relay contacts on a separate terminal block
- Built-in current limiting to the detector in alarm
- Relay driven directly by the detector
- Shorting spring for wiring continuity tests before detectors are fitted
- Tamper-resist feature stops the detector being removed without a tool
- Non-latching: automatic reset once the alarm stimulus has cleared
