The XTL rechargeable battery is used to provide 24 hours of backup battery power when DC power is not

available. The battery is intended for backup power only and not to operate the XTL panel on a daily basis.

If the battery is low, or not plugged into the J1 battery connector, a low battery condition is indicated by the

XTL panel.
Note: If removing the XTL panel from service, disconnect the backup battery from the XTL connector.

Use the following steps to replace the XTL standby battery. DMP recommends replacing the battery every 3

years under normal use.

1.  Unplug the battery connector (J1) from the XTL panel.
2.  Loosen the top PCB snaps.
3.  Lean the panel PCB forward and lift out from the bottom PCB snaps.
4.  Remove and properly dispose of the used battery.

Caution: Risk of fire, explosion, and burns. Do not disassemble, heat above 212°F (100°C),

 

or incinerate.  Properly dispose of used batteries. 

5.  Place the new battery into the XTL housing base with the battery wires directed toward the

bottom right corner. See Figure 4.

6.  Set the XTL PCB into the bottom snaps and press into the top snaps to secure in place.
7.  Plug the battery into the panel connector (J1).

The panel tests the battery once every hour when DC power is present. This test occurs 15 minutes past

each hour and lasts for five seconds. A load is placed on the battery and if the battery voltage is low, a low

battery is detected. If DC power has failed, a low battery is detected any time the battery voltage falls

below 3.7V.
