1 | Overview
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.

To install the keypad mounting plate, fi rst remove the plate from the
back of the keypad.
2.1 | Remove the mounting plate
Removing the mounting plate from the keypad:
1. Insert a slotted screwdriver under the retention clip to release
the clip. Do not pry upwards or twist. Refer to Figure 2.1.
2. With your other hand, slide the mounting plate towards the
bottom of the keypad to unhook the mounting plate from the
keypad. Refer to Figure 2.1.
Figure 2.1: Removing the keypad from base
2.2 | Mount the mounting plate
Choose the fl ush mounting plate (Figure 2.2 left side) for fl ush
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.

3 | Wire the keypad
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.
CAUTION!
Remove all power (AC and battery) before making any
connections. Failure to do so might result in personal injury
and/or equipment damage.
NOTICE!
Do not use a screwdriver on the terminals. Use a ballpoint
pen instead to avoid permanent damage to the terminals.

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.
Figure 3.2: Inserting wire into the terminals
3.1 | Wire to the control panel
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.

3.2 | Wire the inputs
Wire resistance on each sensor input must be less than
100 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.

3.3 | Wire the output
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.
NOTICE!
Do not exceed relay contact ratings of 1.0 A, 24 VDC,
resistive load.
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.
4 | Set the address
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 fi nger or a stylus intended for touch screens
to operate the keypad.
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.

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.

anytime a watch point is faulted.
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.
8 | Proximity reader
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
(125 kHz) credentials. The Bosch ACA-ATR13-RFID tag and Bosch
ACD-ATR11ISO-RFID card are examples.
9 | Confi gure 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 fi re 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).
10 | Addresses, points, and output numbers
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.
Examples
For keypad address 01 the point numbers for the input devices are 11
through 14:
Terminal number 1234
Input number 11 12 13 14
For output devices connected to the NO and C terminals the output
number is 11.
For keypad address 11 the point numbers for the input devices are 111
through 114:
Terminal number 1234
Point number 111 112 113 114
For output devices connected to the NO and C terminals the output
number is 111.
11 | Firmware updates
Firmware updates require a MicroSD card (
Updating the keypad fi rmware:
1. Go to the Bosch website (us.boschsecurity.com) and download
the fi rmware from the B942 product page.
2. Save the fi rmware 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 fl ashes during the update. The
keypad also shows Please wait while programming fl ash.
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 fi ngernail 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.
