Product overview

A wall-mounted gas alarm controller for integrating analog and RS485 field detectors.

Centralized monitoring for field detectors

MIC-1000 is a wall-mounted gas alarm controller for receiving 4–20 mA and RS485 signals from compatible field detectors. Analog input configurations cover one to eight, 16, 24 or 32 inputs, alongside up to 128 RS485 inputs. It provides local concentration display, configurable alarm thresholds and relay control outputs.

The modular controller architecture supports channel expansion and cascading. Local data logging, historical review and optional network or wireless communication support centralized monitoring and record management.
