INSTALLATION

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 5.

For UL installations, all batteries shall be installed

in a DMP Model 350, 349, 341, 342, or 352S

enclosure and all wiring shall run through conduit.

The enclosure shall be installed to the left of the XR100 Series enclosure to ensure Battery and AC wire

separation.

Use sealed lead-acid batteries only: Use the DMP Model 365 (12 VDC 9 Ah), DMP Model 367 (12 VDC

7.7 Ah), Model 366 (12 VDC 18 Ah), Model 368 (12 VDC 4.5 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.

GEL CELL BATTERIES CANNOT BE USED WITH THE XR100 Series PANEL.

6.2 Earth Ground

To provide proper transient suppression, XR100 Series panel terminal 4 must be connected to earth ground using

14 gauge or larger wire. DMP recommends connecting to a cold water pipe, ground rod, or building ground only. Do

not connect to an electrical ground or conduit, sprinkler or gas pipes, or to a telephone company ground.

6.3 Battery Only Restart

When powering up the XR100 Series panel without AC power, briey short across the battery start pads to pull in

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 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.

6.5 Discharge/Recharge

The XR100 Series battery charging circuit oat charges at 13.9 VDC at a maximum current of 1.0 Amps using a

50 VA or 56 VA transformer. Listed below are the various battery voltage level conditions:

Battery Trouble: Below 11.9 VDC

Battery Cutoff: Below 10.2 VDC

Battery Restored: Above 12.6 VDC

6.6 Battery Supervision

The XR100 Series tests the battery when AC power is present. The test is done every three minutes and lasts for ve

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.
