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): 

Remove

battery pack (see

cover) to the battery

connector. Then

remount the cover

and close the door.

 

will be displayed, in addition to “CPU LOW BATTERY”. 
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 

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 

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, 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 

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:

 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. 

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 line trouble:

 Telephone lines may be 

disconnected or short circuited. With the telephone line 
"down", your alarm system will not be able to report events 
to the central station.
