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.
