Secondary Power Supply

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 XR100

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 4.

Use sealed lead-acid batteries only: Use

the DMP 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.

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 XR100 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.
