1 | Overview
The B925F/B926F 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 backlight.
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 RPS.

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.
2.1 | Access the address switches
1.Unlock the keypad by turning the lock counter-clockwise. Refer to Figure 2.1.
2.Hold the keypad by the base in one hand. With the other hand, gently push down on the keypad to remove it from the base. Refer to Figure 2.2.
3.Look at the back of the keypad, and locate the switches. Refer to Figure 2.3

2.2 | Set the address switches
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.
.

3 | Installation
After you set the address switches for the proper address, mount the keypad base, wire to the control panel, and attach the keypad to the base.
Caution!
Remove all power (AC and battery) before making any connections. Failure to do so might result in personal injury and/or equipment damage.
3.1 | Mount the keypad
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.
3.2 | Wire to the control panel
When you wire the keypad to a control panel, use the control panel SDI2 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.
