The ECO1000BREL12L is a 12 V latching relay base for System Sensor ECO1000 conventional detectors. When the detector goes into alarm the relay switches, and it stays latched until the supply to the detector and base is removed.
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
- Latching: alarm is cleared only by removing the supply
- Devices connected to the contacts should not signal an alarm until the contacts have switched for more than 500 ms (prevents nuisance alarms from shock or vibration)
