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.

Gaining access to 24-hour zones

If you wish to access a sensor defined as a 24-hour
zone without causing an alarm:
•
Click - the display will read: USER
SETTING.
•
Click - the display will read: ENTER
CODE ___.
Key your secret 4-digit <User Code> - the buzzer
will play the "happy Tune" (- - - ––––).
You have 4 minutes during which the 24-hour sensor
can be opened and accessed. When the 4 minutes
are up, the system will automatically revert to the
normal mode.

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
alcohol, kerosene, acetone or thinner. These will
certainly ruin the external finish and damage the
transparency of the top window.
