OVERVIEW

The BX150 is a single channel, panel mounted gas detection

controller. It can be connected to toxic and explosive sensors.

If the remote sensor senses the presence of gas, it sends a

proportional 4-20mA signal back to the BX150. When the first

alarm level is reached the pre-alarm relay is activated (See Alarm

Settings). If the level continues to rise the main alarm relay will be

energised.

For explosive or toxic gases, the electrical supply to the safety shut

off valve is broken when the main alarm threshold is reached. A

general alarm is sounded.

Should the controller enter fault condition the safety shut off valve

closes to failsafe. A self-diagnostic feature looks for return sensor

voltage and ensures correct functionality.

The BX150 controller is compatible with all the Duomo conventional

sensors shown on pages 6 & 7.
