InstallatIon

6.1 Battery Terminals 3 and 4

Connect the black battery lead to the negative battery terminal. The negative terminal connects to the enclosure

ground internally through the XR500 Series circuit

board. Connect the red battery lead to the

battery positive terminal. Observe polarity when

connecting the battery.

You can add a second battery in parallel using the

DMP Model 318 Dual Battery Harness. DMP requires

each battery be separated by a PTC in the

battery harness wiring to protect each battery

from a reversal or short within the circuit. See

Figure 6.

Use sealed lead-acid batteries only:

Use the Model 365 (12 Vdc 9 Ah),

Model 366 (12 Vdc 18 Ah), Model 368 (12

Vdc 5.0 Ah), or Model 369 (12 Vdc 7 Ah)

sealed lead-acid rechargeable battery.

Batteries supplied by DMP have been tested to ensure proper charging with DMP products.

the battery cutoff relay. The leads need a momentary short only. Once the relay has pulled in, the battery voltage

holds it in that condition. If the XR500 Series panel is powered up with an AC transformer, the battery cutoff relay is

pulled in automatically. For more information refer to Figure 1.

6.4 Battery Replacement Period

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

seconds. During the test, the panel places a load on the battery; if the battery voltage falls below 11.9 Vdc a low

battery is detected. If AC power is not present, 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 repeats every two minutes until the battery charges

above 12.6 Vdc indicating the battery has restored voltage. If a weak battery is replaced with a fully charged

battery, the restored battery will not be detected until the next two minute test is completed.

6.7 Battery Cutoff

The panel disconnects the battery any time the battery voltage drops below 10.2 Vdc. This prevents battery deep

discharge damage.
