Detector Input Module

The DIM800 Detector Input Module interfaces two collective detector circuits onto the MX addressable loop. Each circuit can support 3mA of detector quiescent current and requires a 4k7 Ohm End Of Line resistor.

The two circuits may be recognised as a single point (MX4428) or two separate points (MX1). Refer to the specific MX fire alarm panel specification. Unused circuits must be terminated with an ELD resistor.

The DIM800 requires a suitably rated and separately protected external 24V supply to power the detector circuits.

 

Use with MX1, MX4428, 4100ESi.
