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.

2 | Install the mounting plate
To install the keypad mounting plate, first 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 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.

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.

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
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 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.

2 ― Keypad sensor loops
3 ― 1 kΩ EOL resistor (ICP-1K22AWG-10)
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 finger 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.
