2. 900 Series Mini Switch Monitor

900 Series Mini Switch Monitor

The II950I is a 900 series addressable mini switch monitor module. It can be fitted onto a 35 mm DIN-Rail with a twist-click motion or mounted in an enclosure such as a manual call point. The II950I is designed to monitor the state of one or more single pole, volt free contacts connected to a single pair of cable and to report this status back to the control panel.

With interrupt faclity feature enabled, the II950I performs the same tasks as in standard mode, but simulates the same response functionality as an addressable manual call point. In this mode the II950I may be used to monitor equipment where a fast response is required. An alarm will be reported to the control panel in less than 3 seconds.
