The B942/B942W Touch Screen Keypad 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.

Callout ― Description
To install the keypad mounting plate, fi rst remove the plate from the back of the keypad.
Removing the mounting plate from the keypad (Figure 2.1):
Figure 2.1: Removing the keypad from base
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:
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.
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.
Figure 3.1: Keypad back (with mounting plate removed)
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
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.

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.
Figure 3.5: Installing sensor loop wiring
Callout ― Description
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.
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.
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.
Figure 4.1 Keypad addressing page
NOTICE! Only use your fi nger or a stylus intended for touch screens to operate the keypad.
Setting the keypad address:
You can diagnose and troubleshoot the system using the keypad's status indicators. Refer to Table 5.1.
Status icon | Function |
Green check - Ready to turn on (arm) | |
Red lock - Turned on (armed) | |
Yellow caution - System trouble | |
Blue GAS - Gas alarm | |
Blue plug - AC power present |
Table 5.1: Keypad status icons
The keypad has a built-in speaker that produces several distinct warning tones. The keypad backlight illuminates when it emits an audible tone.
Tone | Description |
Fire signal | When an area is in fi re alarm, the keypad emits a pulsed, high-pitched bell tone. |
Gas signal | 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 signal | When an area is in alarm, the keypad emits a steady, high pitched bell tone. |
Entrance warning | The keypad emits an intermittent beep tone during entry delay periods to remind the user to disarm the area. |
Exit warning | 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 fl at buzz tone. |
Keypad encoding tone | The keypad emits a muted beep tone as each button is pressed to indicate that the entry was accepted. |
Trouble buzzer | 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 tone | A single clean tweedle tone alerts the user anytime a watch point is faulted. |
Table 6.1: Keypad audible tones
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.
The proximity reader allows users to use a token or card in place of a passcode to turn on or off the security system. The proximity reader supports EM4102 (125 kHz) credentials. The Bosch ACA-ATR13-RFID tag and Bosch ACD-ATR11ISO-RFID card are examples.
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 no | 1 | 2 | 3 | 4 |
Input no | 11 | 12 | 13 | 14 |
For output devices connected to the NO and C terminals the output number is 11.
For keypad address 03 the point numbers for the input devices are 81 through 34:
Terminal no | 1 | 2 | 3 | 4 |
Input no | 31 | 32 | 33 | 34 |
For output devices connected to the NO and C terminals the output number is 31.
To enable the Emergency Key functions use RPS to set the A,B,C Key Response parameters (KEYPADS/Global Keypad Settings) as follows:
Firmware updates require a MicroSD card (2 GB to 32 GB).
Updating the keypad firmware:
Figure 11.1: Inserting a MicroSD card
Use a soft cloth and non-abrasive cleaning solution to clean your keypad (for example, microfi ber cloth and eyeglass cleaner). Spray the cleaner onto the cloth. Do not spray cleaners directly onto the keypad.
