MTL4561 product specification as below for your reference.

MTL4561 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.

Number of channels

Two, fully floating, loop powered

Location of fire and smoke detectors

Zone 0, IIC, T4–6 hazardous area if suitably certified

Div. 1, Group A, hazardous area

Input voltage

6 to 30V dc

Current range
