The Switch Monitor Plus with Isolator is designed to monitor the state of one or more single pole, volt free contacts connected on a single pair of cables and to report the status to Ampac compatible analogue control equipment. Additional circuitry is incorporated to monitor flow switches and provide a time delay. It can also be used to reset a beam detector.
- Output for resetting a remote detector
- Four input states – ’normal’, ’fault’, ’pre-alarm’ and ’alarm’
