Soteria Twin Switch Monitor Unit
The Soteria Twin Switch Monitor Unit provides the function of two Switch Monitor units within one enclosure. The two units are electrically independent of each other. There is a DIL switch on each unit to set the address.
Both Switch Monitor units in the enclosure are designed to monitor the state of one or more single-pole, volt-free contacts connected on a single pair of cables to report the status. It has a selectable status reporting delay making it suitable for monitoring flow switches.
- Improved design for ease or wiring, meaning faster installation
- Short circuit isolator
- Address range 1 - 126
- Compatibility with XP95 and Discovery protocol
