ALARM VOLUMETRIC SURVEILLANCE NOT WORKING

When the alarm is switched on using the remote control, the system is activated correctly but the volumetric sensors do not intervene

The volumetric sensors are connected to the body computer node via an A-Bus serial line.

The volumetric sensors can be excluded by the customer, using the special button. If there is a failure, the body computer node detects and memorizes the causes of the malfunction.
