5.2 Mounting keypads and loop expanders
Security Command keypads have removable covers that allow you to easily mount the keypad to a wall or
other flat surface using the screw holes provided on each corner of the base. Before mounting the base,
connect the keypad wire harness leads to the keypad cable from the panel and to any device wiring run to
that location. Then attach the harness connector to the pin connector on the PC board, mount the base,
and install the keypad cover making sure all of the keys extend through their respective holes.
For mounting keypads on solid walls, or for applications where conduit is required, use a DMP 775, 776, or
778 keypad conduit backbox.
The DMP 711, 714, 715, and 716 expanders are contained in molded plastic housings with removable
covers. The housing base contains the loop expander module and also provides you with mounting holes
for installing the unit to a wall or other surface.
5.3 Connecting serial devices
Keypad data bus
The keypad data bus requires only a 4-wire cable between devices and the panel. You can connect
devices in parallel on the same cable or provide separate runs back to the panel. The maximum cable
length for one keypad can be up to 500 feet using 22 gauge wire or up to 1000 feet using 18 gauge wire.
Additional keypads installed on the same cable decrease the maximum distance at which they'll operate
properly.
Refer to the wiring diagram (section 3.2) in this guide for additional wiring information.
LX-Bus™ (Models 862N, 862P, 872, and 881 Interface Cards)
The LX-Bus provided on these cards also requires only a 4-wire cable between devices and the panel. You
can connect devices together on the same cable with the total cable length for each run being determined
by the number of devices and the gauge of wire being used.
Refer to the table below for determining wiring distances using 22 AWG and 18 AWG.
Note: This table is provided for convenience in determining approximate wiring distances and gauges only.
Individual installations may vary and support greater or lesser distances due to environmental or other
factors.

Primary Power Supply
6.1 AC terminals 1 and 2
Connect the transformer wires to terminals 1 and 2 on the panel. Use no more than 70 ft of 16 gauge, or 40
ft of 18 gauge, wire between the transformer and the 1912XR.
Always ground the panel before applying power to any devices: The 1912XR must be properly
grounded before connecting any devices or applying power to the panel. Proper grounding protects against
Electrostatic Discharge (ESD) that can damage system components. See Earth ground.
6.2 Transformer types
The standard transformer for the 1912XR is 16.5 VAC 40VA, which provides up to 600mA of auxiliary
current. Refer to the 1912XR Wiring Diagram (LT-0182) on the panel enclosure door for a list of optional
transformers. The total current available is limited by the total battery standby requirements.
The transformer must be connected to a 120 VAC 60 Hz commercial power outlet that is not controlled by a
wall switch. Never share the transformer output with any other equipment.
The Model 320 or 322 wire-in transformers are required for NFPA 72 applications.
Secondary Power Supply
7.1 Battery 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 1912XR 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.
You can add a second battery in parallel using the DMP Model 318 Dual Battery Harness.
Use sealed lead-acid batteries only: Use the DMP Model 367, 12 VDC 6.5Ah 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 1912XR PANEL.
7.2 Earth ground
Terminal 4 of the 1912XR panel must be connected to earth ground using 14 gauge or larger wire to
provide proper transient suppression. DMP recommends connecting to a cold water pipe or ground rod
only. Do not connect to electrical conduit or a telephone company ground.
7.3 Battery only restart
When powering up the 1912XR panel without AC power, it's necessary to short across the CR23 leads 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 1912XR panel is powered up with an AC transformer, the
battery cutoff relay is pulled in automatically.
7.4 Replacement period
DMP recommends the battery be replaced every 3 to 5 years under normal use.
7.5 Discharge/recharge
The 1912XR 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 12. The various battery voltage levels are listed below:
Battery Trouble: Below 11.9 VDC
Battery Cutoff: Below 10.2 VDC
Battery Restored: Above 12.6 VDC

Digital Monitoring Products, Inc. 1912XR Installation Guide

Cannot exceed 6.5 with one 367 Battery
Cannot exceed 13.0 with two 367 Batteries
Cannot exceed 19.5 with three 367 Batteries
Cannot exceed 26.0 with four 367 Batteries
Transformer required: Whenever there are three or
four batteries being charged by the 1912XR panel, you
must install the DMP Model 322 Transformer.
7.6 1912XR power requirements
During AC power failure, the1912XR panel and all auxiliary devices connected to the 1912XR draw their
power from the battery. All devices must be taken into consideration when calculating the battery standby
capacity. Below is a list of the power requirements of the 1912XR panel. Add the additional current draw of
Security Command keypads, loop expanders, 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.

7.7 Battery supervision
The 1912XR tests the battery once every hour when AC power is present. The test is done at 15 minutes
past the hour and 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.
7.8 Battery cutoff
The panel disconnects the battery any time the voltage of the battery drops below 10.2 VDC. This prevents
deep discharge damage to the battery.
Bell Output
8.1 Terminals 5 and 6
Nominal 12 VDC is supplied by terminal 5 on the panel to power alarm bells or horns. The output is rated

12.2 Operational parameters
Each burglary protection loop detects three conditions: open, normal, and short.
The parameters for each are listed below:
Condition Resistance on loop Voltage on right terminal
Open over 1300 ohms over 2.0 VDC
Normal 600 to 1300 ohms 1.2 to 2.0 VDC
Short under 600 ohms under 1.2 VDC
12.3 Loop response time
A condition must be present on a loop for 500 milliseconds (1/2 second) before it's detected by the 1912XR
panel. Make sure any detection devices you use on the protection loops are rated for use with this delay.
Loops can also be programmed for a Fast Response delay of 160 milliseconds.
12.4 Keyswitch arming loop (maintained)
Programming a loop as an Arming Type, allows selected areas to arm when the loop is placed into a short
condition. The selected areas disarm when the loop is placed into a normal (1K ΩEOL) condition. If placed
into an open condition from a normal (disarmed ) condition, a trouble is reported. If placed into an open
condition from a short (armed) condition, an alarm is reported and the loop is disabled until another
disarming occurs within the system. The areas controlled by the loop and the relay outputs that indicate
their armed or disarmed status are selected in the panel's Programmer.
