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.
