The B942/B942W is an SDI2 compatible device. The keypad has user
adjustable options such as volume and screen brightness, and has a
display that shows color graphics. The B942 keypad connects to the
SDI2 bus on the control panel. 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
keypad as well as remotely through Remote Programming Software (RPS).
The keypad provides four inputs and one output.

NOTICE!
Use the strip gauge on the mounting plate to strip the
wires to 7 mm. Only one (1) wire per terminal.
Place the keypad on a smooth surface when wiring.
To insert wires into the terminals, use a ballpoint pen to press the
button on the terminal release, and with the other hand, push the wire
into the terminal. (Refer to Figure 3.2.) When you remove the pen, the
terminal release locks in the wire. To remove wires, press the terminal
release, push the wire gently, and then pull the wire out.

2.2 | Mount the mounting plate
3.1 | Wire to the control panel
Choose the flush mounting plate (Figure 2.2 left side) for flush
mounting, or the surface mounting plate (Figure 2.3 right side) for
surface mounting.
Mounting the plate on the wall:
1. The surface plate includes a bubble level. Use the plate as a
template to mark the desired mounting surface with mounting
locations. Refer to Figure 2.2 for mounting hole locations.
2. Pull the wiring through the desired wire opening.
3. Use the appropriate mounting hardware (supplied) to attach the
mounting plate to the mounting surface.
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 (PWR, A, B, COM).
Refer to Figure 3.3.
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 3.4.
Setting the keypad address:
1. When you apply power to the keypad, the start up screen shows. You
can also show the startup screen by pressing and holding the Time/
Date in the ribbon bar for 5 seconds, or by pressing and holding
anywhere on the Call for Service screen. Press screen hold the
countdown icon for 5 seconds. The keypad addressing page shows.
2. To set the address, use the up and down arrows on the right of the
switches image to change the ones digit, and the arrows on the left
to change the tens digit.
3. Press the
(Escape) icon to save the setting and return to the
power up screen.
Figure 3.4: Installing multiple keypads using the SDI2 terminals
(B5512 shown)
3.2 | Wire the inputs
Wire resistance on each sensor input must be less than
100 Ω with the detection devices connected. The terminal block
supports 18 to 22 AWG (1.02 to 0.65 mm) wires.
The keypad detects open, short, normal, and ground fault circuit
conditions on its sensor loops and transmits the conditions to the
control panel. Each sensor loop is assigned a point number and
transmits to the control panel individually. Run wires away from the
premises telephone and AC wiring.

Use the steps below to set the address for the keypad. 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 4.1 shows the address switch setting for address 1.
NOTICE!
Only use your finger or a stylus intended for touch screens
to operate the keypad.

3.4 | Mount the keypad
After wiring the keypad, mount the keypad onto the mounting plate
by seating the mounting hook openings over the mounting hooks
and then sliding the keypad down.
2 ― Terminal wiring
NOTICE!
Do not use a screwdriver on the terminals. Use a ballpoint
pen instead to avoid permanent damage to the terminals.
NOTICE!
Do not exceed relay contact ratings of 1.0 A, 24 VDC,
resistive load.

Figure 2.2: Mounting the plate
Prior to placing the keypad on the mounting plate, wire the keypad to
the control panel, and to any inputs and any output, as desired. The
terminal block for wiring is clearly marked.
The keypad provides one NO (normally open) output. (It includes
NO and C (COMMON) terminals.) When the output is in an active
(energized) state, the NO has continuity with the C terminal.

Region
Certification
The keypad has a built-in speaker that produces several distinct warning
tones. The keypad backlight illuminates when it emits an audible tone.
To determine the point numbers or output number for each keypad
address, multiply the address number by 10 for the base number, and
then use numbers 1 through 4 in the ones place for the point
numbers. Use 1 in the ones place for the output number.

Tone
Description
Fire alarm
When an area is in fire alarm, the keypad 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 fault
A single clean tweedle tone alerts the user
anytime a watch point is faulted.
Table 6.1: Keypad audible tones
7 | Supervision
The control panel supervises all keypads on the SDI2 bus.
If a 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.
9 | Configure programmable keys functions
To enable the programmable keys functions use RPS to set the A,B,C
Key Response parameters (KEYPADS/Global Keypad Settings) as follows:
- To enable the Fire key, set A Key Response to Manual fire alarm.
- To enable the Medical key, set B Key Response to Manual medical
alarm (with or without alarm bell).
- To enable the Panic key, set C Key Response to Manual panic alarm
(invisible or visible).

Firmware updates require a MicroSD card (2 GB to 32 GB).
Updating the keypad firmware:
1. Go to the Bosch website (us.boschsecurity.com) and download
the firmware from the B942 product page.
2. Save the firmware to your MicroSD card.
3. Ensure the keypad is powered.
4. Slide the MicroSD card into the MicroSD card slot until it clicks
into place. Refer to Figure 11.1.
5. The keypad power indicator LED flashes during the update. The
keypad also shows Please wait while programming flash.
6. If the keypad shows the calibration screen, follow the on-screen
instructions to calibrate.
7. When the update completes, the keypad shows Firmware update
successful. Remove SD card to continue.
8. Remove the memory card from the device. To do so, press down
on the card and quickly remove pressure. The card clicks out of
place. Use your fingernail on the upper groove on the card to
slide it out.
9. The keypad shows the power up screen with the updated
revision number and then shows the Home screen.

The proximity reader allows users to use a token or card in place
of a passcode to turn on or off the security system, if programmed
using RPS or a keypad. The proximity reader supports EM4102
