2.1 | Accessing the address switches
3.4 | Wiring to the control panel
After you set the address switches for the proper address,
follow the steps below to install the keypad.
Mounting the mounting plate on the wall:
1. To mark the wall for mounting screw locations, a wire
opening, and a level line, use the mounting plate as a
template.
2. To mount the mounting plate to the wall, use the
included mounting hardware.
3. Pull the wiring through the wire opening.

When you wire the keypad to a control panel, use the control
panel terminals labeled R, Y, G, B (PWR, A, B, COM). Refer to
Figure 3.2.

After wiring the keypad, mount it onto the mounting plate
by seating the mounting hook openings over the mounting
hooks, and then sliding the keypad down.
Apply power to the system and test for proper operation.
3.5 | Mounting the keypad
CAUTION!
Remove all power (AC and battery) before making
any connections. Failure to do so might result in
personal injury and/or equipment damage.
You can connect keypads to the SDI2 data bus by parallel wire
run from the control panel to each keypad, wire from keypad to
keypad, or a combination of the two techniques.
Refer to Figure 3.3.
2 | SDI2 address switches
Address switches determine the address for the keypad. The
control panel uses the address for communications. To set the
switches, use a ballpoint pen.

The keypads have 6 DIP switches that support SDI2
addresses 00 to 32. To set the keypad addresses (per the
control panel configuration), use the DIP switches.
If multiple SDI2 keypads reside on the same system, each
SDI2 keypad must have a unique address. Figure 2.2 shows
the address switch setting for address 01. Refer to Table 2.1
for keypad address settings for address 00 to 32.
2.2 | Setting the keypad address
Removing the mounting plate from the back of the keypad:
1. To release the retention clip, insert a slotted screwdriver
under it. Do not pry upwards. Refer to Figure 2.1.
2. To unhook the mounting plate from the keypad, use your
other hand and slide the mounting plate toward the
bottom of the keypad. Refer to Figure 2.1.
3. Remove the mounting plate.

Figure 1.1: Keypad base overview
The B915 and B915I keypads are SDI2 bus devices. The
keypads connect to the bus using terminal wiring. You can
connect more than one keypad to the control panel by wiring
them in parallel.
You can program, diagnose, and troubleshoot the system from
the control panel keypad, as well as remotely through Remote
Programming Software (RPS).
The B915 function keys are labeled in English. The B915I
function keys are labeled with icons.
The keypad display shows two-line system messages.
Users can adjust the keypad display brightness level, and they
can turn the keypad’s nightlight feature on or off.
Users can adjust keypad volume, and they can turn the key tone
(short tone emitted when a key is pressed) on or off.

To provide tamper protection from prying the keypad from the
wall, optionally install a screw into the tamper location.
Refer to Figure 3.1.
3.3 | Wiring the keypad
Connect the wiring to the keypad terminals labeled R, Y, G, B
before you mount the keypad on the mounting pad. Refer to
Figure 3.2.
