Littelfuse - M4200 blk diagram

The M4200 Alarm Monitor provides a cost effective solution, with the possibility of monitoring eight individual sensors. The inputs can accept NO or NC contacts. Each input can be programmed to control both of the two alarm relays for group alarm outputs. All inputs will, in default mode, activate the alarm relay and the siren relay. The delays for the inputs can be individually selected between 25 milliseconds and 999 seconds.

Cable monitoring provides extra security to the alarm system. It is possible to adjust the brightness and color of the LEDs. Configuration can be done either by dip switches on the back of the unit or by PC.
