Please read and keep care of this manual and the manual of
installed sensors too.
All documentation relating to gas detection plant should be preserved, because it contains
the procedures to be used during the routines verification and / or during the periodic
calibration. We recommend that you always complete the Setup Memorandum Tables
last pages of this
manual. This will facilitate any possible change to the configuration and/or
in case of additional sensors, and operations and maintenance service
The CE424 is a control unit for gas alarm systems up to 24 independent detection points. The
simple installation and easy configuration via the buttons make the unit suitable for use in
many areas, both civil and industrial.
It should be noted that inappropriate use or lack of maintenance can affect the
operation of the device and thus preventing the proper activation of alarms with
potential serious consequences for the user.

The Central has a clock with the automatic DST change. In the absence of power
supply, the clock works with the lithium battery (on the board in the cover), its life, in
normal operation is over 5 years.
If the lithium battery is exhausted and the central remained completely without power, at
startup, you will need to enter the correct date and time
be replaced soon with a new one.
