1.0 Description

The D1255/D1255B Keypad is an SDI Bus compatible device used with Bosch Security Systems control panels. The D1255/D1255B features a keypad that illuminates when you press the keys, a 16-character English language display, and a built-in speaker that emits several distinct warning tones.

The D1255/D1255B Keypad is a low profile, surfacemounted unit.

The control panel supplies all power and data requirements for the D1255/D1255B using a simple four-wire connection. For specific control panel compatibility refer to Table 6 on page 6.

Refer to the Current Rating Chart for Standby Battery Calculations provided in the following documentation, based on which control panel connected to the D1255/D1255B Keypad to determine if you need an additional power supply:

• D9412G/D7412G Approved Applications Compliance

Guide (P/N: 43494) if using a D9412G or D7412G

Control Panel.

• D7212G Approved Applications Compliance Guide

(P/N: 4998138560) if using a D7212G Control Panel.

Configurations combining supervised and unsupervised keypads are also possible.

You can program the control panel to generate messages to the Central Station identifying the supervised keypad that is in trouble. If a keypad loses communication with the control panel for more than 60 sec, the keypad buzzes and CALL FOR SERVICE displays. The control panel transmits a serial device trouble report to the receiver. The keypad shows SDI FAILURE # if the Modem IIIa

communication format

is used or TROUBLE ZN D if the BFSK communication format is used. For more information, refer to the D6600 Computer Interface Manual (P/N: 4998122703).

Depending on programming in the control panel, the D1255/D1255B permits remote control of relays and real time clock display; adding, deleting and changing passcodes; system tests, and more. Refer to the Keypad

and User Interface sections of the D9412G/D7412G Program Entry Guide (P/N: 47775) for complete

programming details on keypad options. You can initiate a variety of system commands with the touch of two or three keys at the D1255/D1255B keypad. To navigate through the system use the four keys near the bottom of the keypad (Item 3 in Figure 1).
