11.0 Arming Devices

11.1 Description

Keypads, maintained or momentary contact

keyswitches, or a combination of the two are used to

arm and disarm areas. The control panel can contain

up to eight areas. Refer to 3.3.6 Areas and Accounts

on page 12 for a description of areas.

For UL 864 Commercial Fire applications,

refer to Installing Combination Fire and

Intrusion Alarm Systems in the

D9412GV2/D7412GV2 Approved

Applications Compliance Guide

(P/N: F01U003639) for important

information about combination fire and

intrusion systems.

11.2 Keypad Terminals 29 to 32

The Bosch Security Systems, Inc. keypad is a four-

wire powered device used to arm and disarm areas,

annunciate complete system status, initiate system

tests, and control many functions of the security

system.

The system can supervise up to eight keypads. The

control panel sends a Serial Device Trouble Report,

SDI FAILURE, in the Modem IIIa

format or

TROUBLE ZN D in the BFSK format, if it loses

communication with a supervised keypad. CALL FOR

SERVICE appears in any keypad that loses

communication with the control panel, if the keypad

has text display capability. SERVC KEYPAD appears

at all other keypads connected to the system.

A total of 32 unsupervised keypads can be connected

to the system. The number of supervised keypads,

number of areas, and the available power affect the

total number of keypads that can be connected to the

system. Refer to Keypad in the

D9412GV2/D7412GV2 Program Entry Guide (P/N:

F01U003636) for complete programming details on

keypad options.

Five types of keypads are available for use with the

system.

• D1255/D1255B/D1255RB

- 16-character

alphanumeric display for general use.

• D1256/D1256RB

- text display keypad with keys

designated for local fire alarm control.

• D1257/D1257RB

- text display keypad for fire

annunciation.

• D1260/D1260B

- easy-to-read, 4-line by 20-

character LCD display with eight “soft” keys to

display simple selections.

• D720/D720B

- LED display keypad appropriate

for use as a single area keypad with up to eight

points.

D1255 and D720 are available in white

(D1255W and D720W) or red (D1255R

and D720R).

To meet UL 864 requirements for

Commercial Fire applications, use a

D1255RB, D1256RB, or D1257RB for a

fire keypad or fire annunciator.

For operational information, refer to the user’s guide

for the specific keypad.

11.2.1 Assigning an Address for the Keypad

Switches on the keypad assign an address (1 to 8).

The address determines if the keypad is supervised,

the scope of the keypad, and to what area the keypad

is assigned. Refer to Keypad Assignment in the

D9412GV2/D7412GV2 Program Entry Guide

(P/N: F01U003636) for a complete description of

addresses.

Table 20 shows the correct switch setting for each

address.
