10.1.1 Relay Outputs

Relay outputs can activate when you are

setting the OctoRelay switches or

programming the control panel.

Disconnect equipment connected to relay

outputs when you perform these functions.

Each OctoRelay output provides a Form C dry contact

rated for 1.0 A at 12.0 VDC. Normally-open, common,

and normally-closed terminals are available for each

relay output. When an individual output is activated,

continuity exists between the normally-open and

common terminals. When the output is not activated,

continuity exists between the normally-closed and

common terminals.

10.1.2 Installation

Set the switches on the OctoRelay before installing it

in the enclosure. Refer to Section 10.1.1 Configuring

the D8129 OctoRelay on page 43.

Install the OctoRelay in the enclosure with the control

panel (Figure 2 on page 8) or in an adjacent

enclosure that is no more than 1.5 m (5 ft) from the

control panel. Use 1.5 mm (16 AWG) to 0.8 mm

(22 AWG) wire.

To install OctoRelays in the enclosure with the control

panel:

1. Align the module with one of the mounting

locations in the enclosure (refer to Figure 2 on

page 8).

2. Using the screws provided with the module,

secure the module in the enclosure.

Use the D137 Mounting Bracket or D9002

Mounting Skirt to install OctoRelays in enclosures

with no available module mounting locations.

10.1.3 Wiring Connections

Power down the control panel to connect OctoRelays.

Refer to Figure 19 on page 43.

OctoRelays for Relays 1 to 24 connect to

Zonex 1, Terminal 28.

Only one OctoRelay is shown wired to each Zonex

bus in Figure 19 on page 43. Wire additional

OctoRelays in parallel. Review Section 6.0 Power

Outputs on page 24 for information about providing

enough power for the relays.

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 four areas. Refer to Section 3.3.5 Areas and

Accounts on page 11 for a description of areas.

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 8 keypads. The

control panel sends a Serial Device Trouble Report,

SDI FAILURE, in the Modem IIIa

format or

Expansion Module Failure (333) in the Contact ID

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 D7212GV3 Program

Entry Guide (P/N: F01U170808) for complete

programming details on keypad options.

Five types of keypads are available for use with the

system.

• D1255/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.

• D1260/1260B: 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).

For operating information, refer to the user’s guide for

the specific keypad.
