Overview

The BX444Mc is a wall or panel mounted microprocessor based gas detector control unit. It has a secure test facility

which allows sensors to be fully tested by applying test gas without disconnecting the electrical supply to Gas valves.

The BX444Mc can be configured to meet customer requirements. The following parameters can be changed using on

board DIP switches:

•

Number of sensors from 1 to 4

•

Type of gas to be sensed (explosive or toxic)

•

Positive Safety Option (on or off)

•

Main alarm relay action (latching or auto-reset)

The BX444Mc has two plug in terminal blocks. One is for the incoming mains supply and alarm circuit wiring and the

second is for connecting the sensor wiring.

This reduces the chance of incorrect site wiring. The front panel has two overload lights which indicate when a short

circuit or an overload has occurred on the sensor wiring.
