Description
System Sensor M221E Dual Input Single Control Output Module
This module provides dual channel monitoring of normally open contact fire alarm and supervisory devices, and also provides single pole changeover contacts for the control of auxiliary devices such as fire shutters and sounders. Three tri-colour LED’s are provided to indicate the status of each channel. LED’s A and B refer to the two input channels.
Each LED has been designed to be set by panel command to pulse green each time the module channel is polled. In case of an alarm the panel can switch the red indicator on continuously. LED C refers to the output channel. The LED can be set by panel command to pulse green each time the channel is polled.
The LED will be switched continuously on green by command from the control panel when the relay contacts are in the energised state. The M221E relay contact ratings are 30VDC, 2A or 30VAC, 0.5A (Resistive load).
