MTL5561 FIRE AND SMOKE DETECTOR INTERFACE MTL 5561

MTL5561 FIRE AND SMOKE DETECTOR INTERFACE MTL 5561

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.
