9. Maintenance

Replacing the Backup Battery

The PowerMaxComplete uses regular electrical

supply, but incorporates backup 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 Chapter 5 - Reviewing Trouble Information):

CPU LOW BATTERY

Figure 10. Battery Replacement

Open battery compartment cover. Insert 6-battery

pack or 8-battery pack and connect its connector to

the PowerMaxComplete receptacle.

Note: Dispose of used backup batteries according to

the manufacturer's instructions.

Note: Removal of the cover 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

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 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.

Replacing Wireless Devices

Batteries

The wireless sensors supplied with your system are

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, 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 PowerMaxComplete 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.
