Marine Mini Switch Monitor

Product Overview

The Marine Mini Switch Monitor is a miniature interface with entirely new housing. The unit is designed to fit into equipment with limited space or mounted within an enclosure such as a manual call point. The interface can also be fitted onto a standard 35mm DIN-Rail using a twist clock motion. The unit is designed to monitor the state of one of more singlepole, volt-free contacts and reports the contact status to Apollo compatible control panels.

The Marine Mini Switch Monitor features a (20i) short-circuit isolator as standard and can be used as an interrupt or non-interrupt device. The interrupt feature means the unit can be used where a priority response is required, in particular for monitoring an individual or a zone conventional manual call point.
