Installation
To install the DGP, do the following:
1. Mount the enclosure. A suitable location includes easy access for wiring, good lighting, suitable access
to power and earth ground, and ample space to work. The mounting surface should be flat and dry. We
do not recommend mounting metal enclosures directly onto concrete walls. Check with local
authorities to verify local codes regarding metal enclosure mounting.
All Alliance system enclosures contain four mounting holes located in the corners of the enclosure.
Use appropriate mounting hardware to mount the enclosure to the mounting surface and the batteries
to the enclosure as shown in Figure 1.

2. Install the standoffs. Before you install the DGP board, configure the appropriate standoffs. Use male/
female standoffs where threaded holes are aligned with the mounting holes on the board and use clip-
in standoffs where square holes are aligned with the mounting holes (Figure 2)
Figure 2. Standoff layouts
3. Install the transformer. Use two 6/32 x 1/4 in. screws to mount the transformer in the enclosure. Install
the rubber grommet into the transformer shield and mount it to the enclosure using four 6/32 x 1/4 in.
screws provided with the transformer (Figure 1 on page 2).
• AL-1255 (24 VAC, AL-1690 Transformer Kit).
• AL-1256/AL-1265 (18 VAC, AL-1672 Transformer Kit).
Note: For AL-1256, FCC requires the use of a Shaffner filter, model FN2060-1-06 with the recommended transformer,
AL-1672.
4. It is important that you provide the proper grounding to the enclosure. Use two male/female standoffs
to secure both the earth ground and enclosure ground wires (Figure 1 on page 2). When securing the
ground wires, use the internal tooth star washers provided with the enclosure between the standoff and
the wire connector. All connections should be tight and make a good electrical connection.
5. Install the tamper switch. Assemble the tamper switch (use the instructions provided with the tamper
switch). Use the three 6/32 x 1/4 in. screws provided to mount the tamper switch.

The TX1 LED should always be active.
RX1. Flashing LED indicates remote units are replying to the polling from the DGP on the local bus.
RS232. Not currently used.
L1 to L4. Indicates unlock relay is active.
DIP switches
There are address and mode DIP switches on the DGP board (Figure 4 on page 4). The mode DIP switches are
currently not used. The address DIP switches (1 to 4) are used to identify this DGP to the control panel (assign
the DGP address). A 4-door/elevator controller DGP can only be addressed as DGP 1 to 12 (Figure 5).

Wiring
The DGP must be wired to both the system bus and the DGP local bus.
Note: FCC requires that shield cables must be used (Belsen 8723 or equivalent).
System bus connections
Keep all panel wiring well away from other wiring. Avoid parallel wire runs with other wires. Where parallel
wire are unavoidable, keep wires a minimum of 2 in. (5 cm) apart or in EMT. We recommend that you wire
Alliance system components that use direct wire transformers into a dedicated circuit breaker and you plug
those that use plug-in transformers into an unswitched outlet.
To correctly earth ground your application, follow these procedures:
One enclosure with several devices. All devices designed for the system have chassis ground
connections via metal studs to the metal enclosure. Take care that these metal studs make good
connections to the enclosure (beware of paint). The earth connection of every piece of equipment in
the system can be used for connecting the shielding of shielded cables. If a device, such as a keypad, is
placed in a plastic enclosure, the earth lug of the device does not have to be connected.
Panels in a single building. If several enclosures or devices are connected to earth ground in one
building, the safety earth ground of this building has to be checked by a licensed contractor.
Panels in multiple buildings. If the wiring extends to separated buildings, more than one common earth
ground system will be used. Use isolator/repeaters to isolate the system bus. In this way the system is
protected against variations in earth potential.
WARNING: Each control panel or device mounted in a metal enclosure, must have its enclosure connected
to earth ground. Correct earth ground procedure must be followed.

7
System bus connections
Connect DGP devices to the system bus to provide extra zones and remote arming stations (RAS) to the
Alliance system control panel. Remote devices can be up to 5,000 ft. (1.5 km) from an Alliance system control
panel. DGP and RAS devices must be connected via a 2-pair twisted, shielded data cable from the system bus
connection. We recommend you use Beldon 8723. Connect the shield of the data cable to earth at the Alliance
system control panel and leave it disconnected at any other end. Where the distance between the arming station
and the nearest device is more than 328 ft. (100 m), use a separate power supply to power the arming station.
To power the arming station do not connect the (+) from the system bus, connect the (+) of the local power
supply to the (+) on the arming station and connect the (0 V) from the power supply and (0 V) from the system
bus to the arming station (-) terminal.
Note: The first and last devices on the system bus must be terminated. All other devices on the system bus must not be
terminated.

Shielded cable routing
Cnnect the shielding of all shielded cables used in the system at one side to one common earthing point in a
building. If a shielded bus cable is routed via more than one plastic device, you must connect the shielding
from in-coming and out-going cable (Figure 7).
Note: Metal chassis must be earth grounded. Splice shield drain wire at all junctions.
Figure 7. Shielded cable routing
Auxiliary power supply connections
In systems where expansion module power is not supplied by the main control panel or an AC-powered DGP
with auxiliary outputs, you must use a UL Listed power supply suitable for burglar alarm applications, such as
the Altonix300ULX. (Figure 8).
Note: Tie all 0V together. Do not connect the +12 together.
