Description
System Sensor M220E Dual Input Monitor Module
This is a dual channel module used for the monitoring of normally open contact fire alarm and supervisory devices. It has two tri-colour LED’s, one referring to each channel. Panel command can set each LED to pulse green each time the module channel is polled.
In case of an alarm the panel can switch the red indicator on continuously. The Yellow LED is controlled by the module and blinks to indicate an open circuit on the input circuit. This fault indication is always overridden by a panel command to turn the red LED on.
