Replacing the Backup Battery

The PowerMaster-10 uses regular electrical supply,
but incorporates rechargeable backup 4.8V battery
pack to ensure its proper operation during a power
failure (see sticker on battery cover). After power
failure the battery is recharged to its full capacity.
Upon receiving CPU LOW BATTERY trouble
message on your LCD display when there is no
power failure or immediately following a power
failure, this indicates a possible fault in the battery
that may require immediate battery replacement. You
should contact your installer to perform this service.

Replacing Wireless Devices Batteries

The wireless devices supplied with your system are
powered by batteries that last several years, in
normal use.
However, if and when a battery becomes weak, the
device itself sends a "low battery" message to the
control panel, and a low battery trouble message is
displayed together with the zone information (see
Chapter 3 - Reviewing Trouble Information).
The respective manuals of these sensors or devices
should be consulted for proper battery replacement
guidelines to be performed by the installer.

Periodic Testing

The components of your security system are
designed to be maintenance-free as much as
possible. Nevertheless, it is mandatory to perform a
"walk-test" at least once a week and after an alarm
event to verify that all system detectors function
properly. Proceed as described in Chapter 4 -
Conducting a Walk-Test, and if there is any problem,
notify your installer at once.

Cleaning the Control Panel

The control panel may occasionally get stained if
touched with greasy fingers, and may accumulate
dust after a long period of use. Clean it only with a
soft cloth or sponge moistened lightly with a mixture
of water and mild detergent, and then wipe it dry.
The use of abrasives of any kind is strictly
forbidden. Also never use solvents such as
kerosene, acetone or thinner. These will certainly
ruin the external
transparency of the top window.
