D1255RB/D1256RB/D1257RB Installation Instructions 1.0 Introduction

1.0 Introduction

Before installing the D1255RB, D1256RB, or D1257RB, you should be familiar with the operation and installation guide and the program entry guide for the control panel you are using. Before proceeding with the installation instructions in this manual, be sure that you are familiar with the programming recommendations in the Guide to UL 864 9th Edition Programming Requirements section of the Introduction in the D9412GV2/D7412GV2 Program Entry Guide

(P/N F01U003636).

2.1.2D1256RB

The D1256RB provides annunciation and system control. Four function keys on the D1256RB provide quick execution of alarm silencing, trouble silencing, annunciator display reset, and sensor reset functions.

The D1256RB should be mounted in a secure area or locked inside an approved clear plastic enclosure.

2.1.3D1257RB

The D1257RB provides remote annunciation without system control capability. It can be mounted in public access locations.

2.1D1255RB/D1256RB/D1257RB

Features

The D1255RB and D1256RB Fire Keypads and the D1257RB Fire Alarm Annunciator are 4-wire serial devices used with the following Bosch Security Systems control panels with firmware version 7.04 or higher:

•D9412GV2

•D7412GV2

•D7212GV2

The D7212GV2 is not approved for commercial fire applications.

Each of these control panels supervises up to eight keypads or annunciators. You can connect a total of 32 keypads or annunciators to the system. The number of supervised keypads or annunciators, number of areas, and the available power affect the total number of keypads or annunciators you can connect to the system.

2.1.1D1255RB

The D1255RB has number keys (0 to 9) and function or menu keys, including [COMMAND] and [ENTER]. The D1255RB can be used as a system controller and an annunciator.

Because a passcode is required to use the keypad, it is usually installed in building entrances and areas with unrestricted access. Near an exterior door in a hotel or in a business lobby is an ideal mounting location, allowing a responding agency or persons evacuating the building to identify quickly the type and location of the emergency from outside without being in danger.

Two keys on the D1257RB allow the user to select forward or backward through a list of system events.

2.2Description

2.2.1Display

The D1255RB, D1256RB and D1257RB use a

16-character display with custom programmable text. The custom text programmed at the control panel appears in the vacuum fluorescent display (VFD). Refer to Figure 1, Item 1.

The keypads and annunciator show the latest status conditions of the fire system using words, numbers, and symbols. When an alarm occurs, a message remains in the display until the user acknowledges the event at a keypad or annunciator. When a series of events affecting the system occurs, each event appears in order of its priority.

2.2.2Audible Tones

The D1255RB, D1256RB and D1257RB have a built- in speaker that produces several distinct warning tones. To change the speaker volume, adjust the potentiometer (Figure 1, Item 3). Turn the potentiometer clockwise to increase and counterclockwise to decrease the volume.

You cannot connect external annunciation devices to the D1255RB, D1256RB, and

D1257RB.

•Fire Signal – Pulsed, high pitched bell tone when the system is in alarm

•Invalid Key Buzz – Flat buzz tone when an invalid key, or sequence of keys, is pressed

•Keypad Encoding Tone – Muted beep tone as each key is pressed to indicate that the entry has been accepted. To disable the keypad encoding tone, refer to Section 2.2.3 Switch Settings.
