Product overview

MTL5561 2channel loop-powered, for fire and smoke detectors 

              MTL5561 2channel loop-powered, for fire and smoke detectors

MTL5561 product specification as below

MTL5561 2channel loop-powered, for fire and smoke detectors

MTL4561 – MTL5561 FIRE AND SMOKE DETECTOR INTERFACE 2-channel

The MTLx561 is a loop-powered 2–channel interface for use with conventional fire and smoke detectors located in hazardous areas. In operation, the triggering of a detector causes a corresponding change in the safe–area current. The unit features reverse input polarity protection.
