Installation

Secondary Power Supply

6.1Battery terminals 3 and 4

Connect the black battery lead to terminal 4 on the panel and to the negative terminal of the battery. The negative terminal connects to the enclosure ground internally through the XR6A/XR10A/XR20A circuit board. Connect the red battery lead to terminal 3 on the panel and to the positive terminal of the battery. Observe polarity when connecting the battery. The panel can charge up to two batteries.

Use sealed lead-acid batteries only: Use the DMP Model 367, 12 VDC 7.0Ah sealed lead-acid rechargeable battery. Batteries supplied by DMP or manufactured by Eagle Picher or Yuasa have been tested to ensure proper charging with DMP products.

GEL CELL BATTERIES CANNOT BE USED WITH THE XR6A/XR10A/XR20A PANEL.

6.2Earth ground

Terminal 4 of the XR6A/XR10A/XR20A panel must be connected to earth ground using 14 gauge or larger wire to provide proper transient suppression. DMP recommends connecting to a metal cold water pipe or ground rod only. Do not connect to electrical conduit or a telephone company ground.

6.3Replacement period

DMP recommends the battery be replaced every 3 to 5 years under normal use.

6.4Discharge/recharge

The XR6A/XR10A/XR20A battery charging circuit float charges at 13.9 VDC at a maximum current of 1.2 Amps using a 40VA transformer. The total current available is reduced by the combined auxiliary current draw from terminals 7, 11, and 25. The various battery voltage levels are listed below:

Battery Trouble:

Below

11.9 VDC

Battery Restored:

Above

12.6 VDC

6.5Battery supervision

The XR6A/XR10A/XR20A tests the battery once every hour when AC power is present. The test lasts for five seconds. A load is placed on the battery and if its voltage falls below 11.9 VDC a low battery is detected. If AC power has failed, a low battery is detected any time the battery voltage falls below 11.9 VDC.

If a low battery is detected with AC power present, the test is repeated every two minutes until the battery charges above 12.6 VDC; the battery restored voltage. If a faulty battery is replaced with a fully charged battery, the restored battery will not be detected until the next two minute test is done.

6.6XR6A/XR10A/XR20A power requirements

During AC power failure, the panel and all auxiliary devices connected draw their power from the battery. All devices must be taken into consideration when calculating the battery standby capacity. On the following page is a list of the power requirements of the XR6A/XR10A/XR20A panel. Add the additional current draw of Security Command keypads, smoke detector output, and any other auxiliary devices used in the system for the total current required. The total is then multiplied by the total number of standby hours required to arrive at the total Ampere/hours required.
