Alarm module operation check
Like for the sensors, after the system is calibrated and started up, it is necessary to make
sure the alarm modules are operating correctly. For this purpose, terminals + and - of the
input to check need to be short-circuited (or the digital status of the system connected to the
input needs to be switched); check that the relative LED on the module has switched on,
and the status of the control unit input using the dedicated SYSTEM STATUS menu
described below.
Alarm engagement can also be checked by observing the reaction of the engagement and
display devices (RM and DM) assigned to it.

Displays on the display module
The display module displays any alarms detected by the gas detectors or AM it is assigned
to. A display on a display module that is not configured and not assigned is blank.
