Installation Instructions
1.0 Description
The D1255TD Command Center is an SDI buss compatible device used with Bosch Security Systems control/communicator
panels. The D1255TD features a keypad that illuminates when you press the keys, a sixteen-character English language
display, and a built-in speaker that emits several distinct warning tones.
The panel supplies all power and data requirements for the D1255TD via a simple four-wire connection. For specific panel
compatibility refer to Table 1: Panel Compatibility Chart, p. 2 of this document. See the Current Rating Chart for Standby
Battery Calculations provided in the Operation and Installation Guide for the specific panel used with the D1255TD to
determine if you need an additional power supply. Configurations combining supervised and unsupervised command
centers are possible.
You can program the panel to generate messages to the D6500 identifying the supervised command center that is in trouble.
If a command center loses communication with the panel for more than 60 seconds, the command center buzzes and CALL
FOR SERVICE displays. The panel transmits a serial device trouble report (SDI FAILURE in Modem, TROUBLE ZN
D in BFSK) to the receiver.
Depending on programming in the panel, the D1255TD permits remote control of relays and real time clock display; adding,
deleting and changing passcodes, system tests, and more. See the Command Center and User Interface sections of the Program
Entry Guide for complete programming details on command center options. You can initiate a variety of system commands
with the touch of two or three keys at the D1255TD keypad. To navigate through the system use the five keys near the bottom
of the keypad.
