9. MAINTENANCE

9.1 Replacing the Backup Battery

The PowerArt™ operates from the regular electrical supply

of the protected site, but incorporates an internal 9-Volt

battery that keeps it working during power failures. It is

extremely important to maintain this battery in good

condition, namely to replace it immediately upon getting

the following trouble message when reviewing system

troubles (see Para. 5.2B):

CPU LOW BATTERY

Replacing the battery is a relatively simple process, so you

do not have to bother your installer. Proceed as follows:

A . Prepare 6 AA-size alkaline battery cells (option 1) or 6

size AA, 650 mA/h Nickel-Cadmium cells (option 2) -

purchased in any hardware or electrical supply store.

B . Make sure that the keypad cover is open.

C . Insert a wide bladed screwdriver into the slot shown in

Figure 11, and turn the handle slightly to force the right

edge of the left-hand cover up. This should dislodge

the two catches and free the right edge of the cover.

Warning! Do not try to dislodge the left side of the

cover first! This will break the angled legs at the left.

Figure 11. Prying the Cover Loose

D . Swing the cover up as shown in Figure 12, then pull

free the angled legs at the left and put the cover away.

The inner lid will now be in full view (see Figure 13).

Figure 13. Battery Compartment Lid

E. Remove the screw that secures the battery compartment

lid (Fig. 13), swing the lid up and pull it away. You have

thus gained access to the battery holder (see Fig. 13).

ATTENTION! Removal of the lid 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”.

F . Pull the battery holder out and replace all 6 battery cells -

3 at the top and 3 at the bottom. Make sure that the flat

(negative) end of each cell is pressed against a circular

spring and the capped (positive) end of each cell is

pressed against a flat contact.

CAUTION! If you replace rechargeable cells

with alkaline (dry) cells or vice versa, mount

the battery-type selector in the correct

position (CHRG for rechargeable cells and

DRY for alkaline cells - see Figure 15).
