Bosch SDI2, B930 - ATM Style Alphanumeric Keypad Installation Manual

Overview

B930 keypads are SDI2 bus compatible devices. Each keypad has user adjustable options such as volume and display brightness, and an LCD display that shows five-line system messages.

B930 keypads connect 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).

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.

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
   

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.

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.

Remove all power (AC and battery) before making any connections. Failure to do so might result in personal injury and/or equipment damage.

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.

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.

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.

7. Press [ESC] to exit the menu.

Status indicators

You can diagnose and troubleshoot the system using the keypad's status indicators. Refer to Table 5.1.

Table 5.1: Keypad status indicators

Status indicator	Function
	Ready to turn on (arm)
	Turned on (armed)
	System trouble
GAS	Gas alarm
	AC power present

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.

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.

Show the firmware version

Showing the keypad firmware 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 firmware version for 10 seconds.

NOTICE!
You can also view a keypad's firmware version in RPS.

Use a soft cloth and non-abrasive cleaning solution to clean your keypad (for example, microfiber cloth and eyeglass cleaner). Spray the cleaner onto the cloth. Do not spray cleaners directly onto the keypad.
