Manual control unit

The BCM (Manual Control Box) must only be used in conjunction with the Self-Triggering Detector. It is based on standard EN 54-11 and has a choice of two labels indicating the type of function: Smoke Control and Compartmentalisation.

The BCM is actuated by a deformable membrane, after which the yellow marking appears.
To reset it, insert a key in the holes provided on the underside of the device: simply press the key vertically to return the Manual Control Box to standby mode.

 It has been designed to enable the user to :

• Better visibility of the device's alarm status
• It can be activated and reset as many times as required, thanks to its self-deforming membrane, which eliminates the need to change the glass.
