The Mini Switch Monitor is an interface within an entirely new housing. Designed in response to customer feedback, the smaller Mini Switch Monitor can be fitted onto a 35mm DIN-Rail with a twist-click motion or mounted in an enclosure such as a manual call point.
 
It is designed to monitor the state of one or more single pole, volt free contacts connected to a single pair of cables and to report the status to Apollo compatible control equipment.
 
The monitor is designed to fit into equipment with limited space or to be mounted within an enclosure such as a manual call point. The interrupt feature means the monitor can be used where a priority response is required, in particular for monitoring an individual or a cone of conventional manual call points.
