the keypad to the base.
3.1 | Mount the keypad
3.2 | Wire to the control panel
You can surface mount the keypad, or mount it to standard
electrical boxes, including single gang boxes.
Mounting the keypad:
1. Use the base as a template to mark the desired mounting
surface. Refer to Figure 1.1 for mounting hole and wiring
locations.
2. Pull the wiring through the desired wire opening in the
base.
3. Use the appropriate mounting hardware (supplied) to
mount the base to the desired mounting surface. Refer
to Figure 1.1 for mounting hole and wiring locations.
When you wire the keypad to a control panel, use the control
panel terminals labeled R, Y, G, B (PWR, A, B, COM). Connect
them to the keypad terminals labeled R, Y, G, B. Refer to
Figure 3.1.
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 3.2.

2 | SDI2 address switches
Two switches determine the address for the keypad. The control
panel uses the address for communications. Use a slotted
screwdriver to set the switches.
Figure 2.1: Unlocking the keypad
Figure 2.2: Removing the keypad from base
Set the address switches per the control panel configuration.
If multiple SDI2 keypads reside on the same system, each
SDI2 keypad must have a unique address. For single-digit
addresses 1 through 9, set the tens switch to 0. Figure 2.4
shows the address switch setting for address 1.

The B920 keypad is an SDI2 bus compatible device. Each
keypad has an LCD display that shows two-line system
messages, and user adjustable options such as volume and
display brightness.
The keypad connects to the SDI2 bus on the control panel
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).

9 | Keypad cleaning
Use a soft cloth and non-abrasive cleaning solution to clean your
keypad (for example, microfiber cloth and eyeglass cleaner).
Spray the cleaner onto the cloth. Do not spray cleaners directly
onto the keypad.
Showing the keypad firmware version:
1. Remove the keypad from the base to remove power to the
keypad. Refer to Figures 2.1 and 2.2.
2. Return the keypad to the base to restore power.
The keypad shows the model number, keypad address, and
firmware version for 10 seconds.
8 | Show the firmware version
NOTICE!
You can also view a keypad’s firmware version in RPS.
The control panel supervises all keypads on the SDI2 bus.
If a supervised keypad fails to respond to the control panel,
the control panel declares a Missing Keypad Trouble. When
the control panel can again communicate with the keypad, it
restores the Missing Keypad Trouble.
During a Missing Keypad Trouble, any connected keypad that
maintained contact with the control panel shows the Missing
Keypad Trouble as its idle text, and shows the missing
keypad’s address. The communicating keypads also sound a
trouble tone. Users can silence the trouble tone. If no other
troubles exist, the tone silences when the missing keypad
restores.
7 | Supervision
6 | Audible tones
The keypad has a built-in speaker that produces several distinct
warning tones. The keypad backlight illuminates when it emits
an audible tone.

emits a pulsed, high-pitched bell tone.
Gas alarm When a gas point activates, the keypad
emits a unique high pitched tone.
User alarm When a user alarm (such as panic and
medical alarms) occurs, the tone sounds
for the programmed amount of time.
Burglary alarm When an area is in alarm, the keypad
emits a steady, high pitched bell tone.
Entry delay The keypad emits an intermittent beep
tone during entry delay periods to remind
the user to disarm the area.
Exit delay The keypad emits an intermittent beep
tone during exit delay.
Invalid button
buzz
When an invalid button, or sequence of
buttons, is pressed, the keypad emits a
flat buzz tone.
Keypress The keypad emits a muted beep tone as
each button is pressed to indicate that
the entry was accepted.
Trouble When a trouble event occurs, such as a
service alert, the keypad emits a two-tone
warble until you enter a programmed
passcode with the appropriate authority.
Watch point

A single clean tweedle tone alerts the
user anytime a watch point is faulted.
