9. MAINTENANCE
9.1 Replacing the Backup Battery
The PowerMax+ uses regular electrical supply, but
incorporates backup 7.2/9.6V battery pack (see sticker on
battery cover). It is important to replace it immediately
upon receiving the following trouble message when
reviewing system troubles (see Para. 5.2B):

Note: Removal of the cover shown in step 2 will start a
“tamper” alarm - the trouble indicator will light and both
“memory” and “trouble” will flash in the display window. If you
interrogate the system at this stage by clicking the <OK>
button, “CPU TAMPER ALARM” and “CPU TAMPER OPEN”
will be displayed, in addition to “CPU LOW BATTERY”.
With correctly inserted fresh batteries and tight closure of the
With correctly inserted fresh batteries and tight closure of the
lid, the TROUBLE indicator should extinguish. The “MEMORY”
message will continue blinking in the display (caused by the
“tamper” alarm you triggered). Clear it by arming the system
and disarming it as soon as the exit delay starts.
9.2 Replacing Wireless Devices 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
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 Para. 5.2).
The keyfob transmitters used to control the system are
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
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, and 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 device 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+ 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.

9.3 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 Para. 6.8, and If
there is any problem, notify your installer at once.
9.4 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
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.
10. PERFORMANCE LIMITS
Although the alarm control system you purchased is highly
reliable, it does not guarantee protection from burglary and
fire hazards. Even the most advanced systems can be
defeated or might occasionally fail to warn. Some of the
reasons for this are:
Sloppy maintenance:
reliable, it does not guarantee protection from burglary and
fire hazards. Even the most advanced systems can be
defeated or might occasionally fail to warn. Some of the
reasons for this are:
Sloppy maintenance:
If the system is used over a long
period of time without testing, a key element such as a
detector or a siren might go wrong without any visible or
audible signs of failure. If a low battery warning is
neglected, there will be no backup power to keep the
system operational during a power outage.

audible signs of failure. If a low battery warning is
neglected, there will be no backup power to keep the
system operational during a power outage.
Power failures:
In case of prolonged absence from the
protected site, the mains supply may suddenly fail (an earth
leakage protection relay may trip, disconnecting the mains
supply). After such an event, the alarm system will draw
power from the backup battery, until all reserve power is
exhausted, leaving the premises without protection.

Telephone lines may be
