9. Maintenance
Replacing the Backup Battery
The PowerMax Pro uses regular electrical supply,
but incorporates backup 9.6V battery pack (see
sticker on battery cover). Upon receiving the
following trouble message when reviewing system
troubles (see Chapter 5 - Reviewing Trouble
Information), contact your installer for instructions on
how to proceed:
CPU LOW BATTERY
Front

Figure 10. Battery Replacement
Open battery compartment cover. Insert one 8-
battery pack and connect its connector to the
PowerMax Pro receptacle.
For optional two 8-Battery packs: Insert both
battery packs and connect one battery pack
connector to either receptacle and the second
battery pack connector to the other receptacle.
Note: Dispose of used backup batteries according to
the manufacturer's instructions.
Note: Removing the cover starts a Tamper alarm.
The trouble indicator will light and both Memory and
Trouble will flash in the display window. If you view
the display at this stage by clicking the
key, the "CPU TAMPER ALARM" and "CPU
TAMPER OPEN" messages are displayed in addition
to the "CPU LOW BATTERY" message.
When you correctly insert fresh batteries and close
the lid tightly, the TROUBLE indicator shuts off. The
MEMORY message continues blinking in the display
(because of the Tamper alarm you triggered). Clear
it by arming the system and disarming it as soon as
the exit delay starts.
Replacing Wireless Sensors Batteries
The wireless sensors supplied with your system are
powered by high-capacity lithium batteries that last
several years, depending on the number of times the
sensor is triggered into transmission.
However, if and when a battery becomes weak, the
sensor 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 5 - Reviewing Trouble Information).
The keyfob transmitters used to control the system
are powered by an alkaline battery that lasts about
one year if you do not press a button more than 10
times a day. Battery exhaustion is clearly evident by
flashing of the transmitter’s red indicator while the
button is pressed (instead of lighting steadily).
When a low battery indication appears for the first
time, it may be considered as a pre-warning. It
normally gives you ample time (about 30 days) to
obtain a new battery and replace the old one; the
detector or keyfob unit will be fully operational
throughout this period. However, to be on the safe
side, it is advisable not to wait that long.
Use the battery specified in the detector’s own
installation instructions. If you do not have the
instructions, seek the advice of your installer or ask
him to replace the battery in the specific sensor that
sent the low battery message.
The Wireless Commander is powered by a long life 3
V Lithium battery. If the battery is weak when reading
the PowerMax Pro event log the display will read, for
example, "C01 Low Battery" (meaning there is a low
battery condition in the wireless commander #01), and
the message "remote commander" will be heard.
For replacing the wireless commander battery, refer
to the MCM-140+ Wireless Commander user guide.
After battery replacement, the detector unit will send
a “battery restored” signal to the control panel, and
the “low battery” message will be cleared.
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 6 -
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 finish and damage the
transparency of the top window.
