Bosch CM704B 8-Zone Expansion Module for Solution 6000 Alarm Panel

SKU: CM704B
Description

The Bosch CM704B adds hardwired zones to a Bosch Solution control panel. Each module provides eight physical zone inputs and, depending on the end-of-line wiring, expands the panel by either 8 or 16 zones. It connects over the RS485 keypad LAN, so it can sit inside the panel enclosure or be located remotely near the detectors, and it can be powered from the panel LAN or a local supply. It suits the Solution 16i and Solution 6000 panels.

Key points
- Adds 8 physical zone inputs (8 or 16 zones with end-of-line wiring)

§ 01Overview

What the CM704B is

The Bosch CM704B is a zone expansion module that lets a Bosch Solution panel watch more detectors than its on-board zones allow. Each CM704B gives eight extra physical zone inputs, and with double-end-of-line wiring that becomes up to 16 zones per module, so you can scale a system up as a building or its security needs grow. It suits the Solution 16i and the Solution 6000 panels.

Because it is LAN-based, it is flexible to place. It connects to the panel over a four-wire RS485 LAN and can sit in the main enclosure or be mounted remotely close to a group of detectors, which saves running every detector cable back to the panel. It can draw power from the panel LAN or from a local supply (the input is current-limited to 1 A), and a separate tamper input means it can live in its own enclosure without using up a detection zone for cabinet tamper.

It is built to be installer-friendly. A status LED flashes when the module is communicating correctly and goes steady on a communications fault, a zone-power LED shows the zone terminals are powered and not overloaded, and a service code-pad connection lets a technician plug a keypad in locally for maintenance when the module is away from the panel. Each module is given its own address on a three-way dip switch and is recognised automatically by the panel. It is genuine Bosch stock with local 3-year warranty.

§ 04Why choose this

Built for the way you actually use the CM704B

Grow the system

Add 8 - or 16 with end-of-line wiring - hardwired zones per module as the site expands.

Save cabling

Mount it remotely near a group of detectors and run a single RS485 LAN back to the panel.

Flexible power

Draw power from the panel LAN or a local supply, with the input current-limited for safety.

Easy to commission

Dip-switch addressing, auto-recognition and clear status LEDs make it quick for an installer to set up.

§ 05Where it fits

Right at home in these scenarios

Outgrown the on-board zones

Add zones to a Solution 16i or 6000 when the panel's built-in inputs are full.

Large or spread-out sites

Place modules near detector clusters in a big home or commercial building to cut cable runs.

Staged expansions

Add a module at a time as new areas or detectors are brought into the system.

Separate tamper-protected enclosure

House the module in its own box and use the separate tamper input for cabinet protection.

§ 06Setup

Installation & setup

01

What's in the box

One CM704B zone expansion module (PCB). The control panel, enclosure, cabling and any local power supply are not included.

02

Installation requirements

A licensed installer mounts the PCB in the panel enclosure or a remote box, connects it to the panel over the four-wire RS485 LAN, and sets its address on the three-way dip switch. Power it from the panel LAN or a local supply (input current-limited to 1 A), wire the zone inputs with the chosen end-of-line configuration for 8 or 16 zones, and use the separate tamper input for cabinet tamper. Keep LAN runs within 300 m (security cable) or 1500 m (Belden 8723).

§ 07Questions

Frequently asked about the CM704B

Q.01

Which panels does the CM704B work with?
It is a zone expansion module for the Bosch Solution 16i and Solution 6000 intrusion panels. It connects over the RS485 keypad LAN and is recognised automatically once it is addressed.
Q.02

How many zones does it add?
Each module provides eight physical zone inputs. Depending on the end-of-line resistor configuration you use, that gives either 8 or 16 zones per module, so you can add several modules to reach the panel's maximum.
Q.03

Can I mount it away from the panel?
Yes. Because it is LAN-based it can sit inside the main enclosure or be located remotely near a cluster of detectors, connected back to the panel over a four-wire RS485 LAN. That can save a lot of cabling on a larger site.
Q.04

How is it powered?
It can be powered from the control panel LAN or from a local external supply, with the power input internally current-limited to 1 A. It runs on 10.5 to 14 VDC and draws about 100 mA.
Q.05

How far can the LAN run?
Using multi-stranded security cable the total LAN length can be up to 300 m, and using two-pair twisted shielded data cable (Belden 8723) up to 1500 m, which gives plenty of reach for remote modules.
Q.06

Does it have its own tamper?
Yes. It has a separate tamper input, so when you house the module in its own enclosure you can wire cabinet tamper to it without sacrificing one of the detection zones.
Q.07

How do I know it is working?
A module status LED flashes when it is communicating correctly with the panel and stays steady if there is a communications failure, and a zone-power LED shows that zone power is present and not overloaded.

§ 09Bundles

Recommended packages

02

Operate the system

Pair the panel with a CP736B graphic keypad and bring it online with the CM751B IP module.

03

Fill the new zones

Wire the extra zones to detectors such as the BDL2-W12G TriTech or DS936 360-degree PIR.
