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
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, 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.
