Alarm Monitor

Description

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.
