M221E Input Output Module
M221E Input Output Modules 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.
Overview
The System Sensor Analogue Addressable Dual Input Single Output Module M221E supervises two input circuits from external devices and also provides an unmonitored single pole volt-free changeover contact for external devices. Input channels are capable of both latched and analogue supervision there are three separate latched states Normal, Open-Circuit and Combined Alarm/Short. The analogue supervision continuously monitors the supervised circuit, returning a signal proportional to the circuit resistance.
