1 | Overview

The B920 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 display brightness.

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 Remote

Programming Software (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.

2.2 | Set the address switches

Set the address switches per the control panel confi guration.

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 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.

Figure 3.2: Installing multiple keypads using the SDI2 terminals

Reconnect the keypad to the base by sliding the keypad onto the base (reverse of Step 2). The keypad automatically locks onto the base. Apply power to the system.

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.

Tone

Fire alarm

Description

When an area is in fi re alarm, the keypad emits a pulsed, high-pitched bell tone.

Gas alarm

User alarm

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

Invalid button buzz

Keypress

The keypad emits an intermittent beep tone during exit delay.

When an invalid button, or sequence of buttons, is pressed, the keypad emits a fl at buzz tone.

The keypad emits a muted beep tone as each button is pressed to indicate that the entry was accepted.

Trouble

Watch point fault

When a gas point activates, the keypad emits a unique high pitched tone.

When a user alarm (such as panic and medical alarms) occurs, the tone sounds for the programmed amount of time.

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.

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 supervised 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 | Show the fi rmware version

Showing the keypad fi rmware version:

1. Remove the keypad from the base to remove power to the keypad. Refer to Figures 2.1 and 2.2.

2. Return the keypad to the base to restore power.

The keypad shows the model number, keypad address, and fi rmware version for 10 seconds.

NOTICE!

You can also view a keypad’s fi rmware version in RPS.

9 | Keypad cleaning

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.
