The D1255/D1255B Keypad is a low profile, surface- mounted 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 IIIa2 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).
