CM704B - 8/16 Zone Expander Module
The CM704B allows you to expand the hard wired zone capacity of se-
lected Vision control panels.
Table 1: lists the panels which are compatible with the CM704B and the
maximum number of expanders that can be supported on each.
Depending on the end of line (EOL) resistor option selected, each
CM704B installed will add 8 or 16 zones to the system.

Solution 144 8
Solution E 16
Table 1: CM704B Compatibility
The CM704B is supplied as a PCB module and can be installed in the
same cabinet as the main panel or remotely from the panel using the
encrypted, 4 wire RS485 LAN connection. The module requires only one
space in the enclosure and is supplied with all necessary EOL resistors
and mounting hardware. Sensors connected to the expander can be
powered from the Vision panel,(1) or from an external power supply like
the CM720B or CM723B power supply modules.(2)
Power is connected to the module dierently depending on the connec-
tion method required. Refer to Figure 2: and Figure 3: on page 5 for
LAN / Power wiring diagrams.
A dedicated service keypad and tamper input are provided. If the tamper
input is not required, you should t the supplied shunt to the tamper
input pins. To assist with installation, the module includes indicators to
show Module and Zone Power status at all times.
A four way dip switch is used to select the zone expander modules
address. The address setting determines the zone numbers for each
expander as shown in Table 2: and Table 3: on page 4. You should
consult these tables before you begin zone programming
Programming Considerations
1) The CM704B expander does not need to be enabled via panel pro-
gramming. The panel will recognise it after power cycle or after per-
forming a LAN scan function (MENU 6-0-2).
2) The EOL resistor value selected in the panel programming is global for
all zones in the system including zones on expanders.
3) Some zones are defaulted as Not Used in panel programming. These
must be programmed as valid zone types before they become active.

Zone Conguration
On panels with a zone capacity greater than 16, (Solution 144, Solution E) each CM704B zone expander module
installed on the system will occupy 16 zones regardless of the EOL resistor conguration selected. See “Table 3:
CM704B Address Conguration On Solution E and Solution 144 Panels” on page 4 for more information.
Depending on the EOL resistor option selected, only one CM704B can be installed on panels with a maximum zone
count of 16 zones. (Solution 16i). See “Table 2: CM704B Address Conguration On Solution 16i Panel” on page 4
for more information.
Single EOL Monitoring
If single EOL resistor conguration has been selected and one CM704B zone expander has been installed at address
1, the system provide zones 1 to 8 on the main panel and zones 17 to 24 on the expander module.
Split EOL Monitoring
If the Split EOL resistor conguration has been selected and one CM704B zone expander has been installed at ad-
dress 1, the system provides zones 1 to 16 on the main panel and zones 17 to 32 on the expander module.
Alarm + Tamper Monitoring
If the Alarm + Tamper monitoring EOL resistor conguration has been selected and one CM704B zone expander has
been installed at address 1, the system will provide zones 1 to 8 on the main panel and then zones 17 to 24 on the
expander module. 2K2 + 6K8 and 10K + 10K EOL resistor values options can also be selected for Alarm and Tamper
Monitoring.
RF Zones
If an RF receiver has been installed, then all zones up to the maximum number supported by the panel become avail-
able for use as RF zones.
An RF zone can be assigned or mapped to any spare zone input allowing zone parameters to be programmed.
Assigning an RF zone to a physical zone will override or ignore the hard wired zones physical input terminals. For
example if zone 7 is congured as an RF zone then any devices connected to the zone 7 terminals will be ignored.
i
Note
The EOL resistor value setting is a global panel option. This means that all zones on the system must use the same
EOL resistor values. EOL resistors are not required for RF Zones.
Module Address Switches and Zone Numbering
Table 2: and Table 3: list the module address settings and corresponding zone numbers that apply when adding zone
expanders to the listed panels. Each zone expander module added to the Solution 16i will provide a maximum of
8 additional zones. Zone expanders should not be tted to this panels when the Split EOL resistor option has been
selected.
i
Note
Only one CM704B can be assigned to each address. All mod-
ules are supplied from the factory set to address 1. You must
power cycle the panel or perform a LAN scan whenever you
change the module address. The LAN must be in the unlocked
state or the LAN scan will not nd new modules.

Figure 2: Connection Diagram With Power Supplied By System LAN+
Figure 3: Connection Diagram With Power Supplied By External Supply
To power the module and sensors from the panel LAN connect the wiring as shown. Care must be taken to
ensure that the load does not exceed the maximum LAN+ current. When the module is located more than 100m
from the panel the use of an external power supply (CM720B or CM723B) is recommended. See the Installer Refer-
ence Guide for more information on available current and wiring options.
To power the module and sensors etc from an external power supply (CM720B or CM723B) connect the wiring as
shown. In this situation, the LAN+ terminal of the module is connected to the external power supply (CM720B or
similar) and must NOT be connected to the panel LAN+ terminal. See the Installer Reference Guide for more infor-
mation on available current and wiring options.
Powering The CM704B From An External Power Supply
Powering The CM704B From The LAN
i
Note
The power source connected to the LAN+ terminal on the module is internally connected to the +12V power output
terminals via a 1 amp resetting fuse. This means that devices powered from these terminals are eectively being
supplied from the power supply connected to the LAN+ terminal.
When the Power OK LED is on the power output is OK. The fuse will open and the LED extinguish if the power out-
put terminals are overloaded.
The maximum continuous current drawn from the (+12V) power output terminals should not exceed 500 mA when
being powered from the LAN or 1 Amp when powered via an external power supply.

In the interest of ongoing product development this
document is subject to change without notice.
The Solution 144 and Solution E panels also support the CM705B Universal Expander Modules. The CM705B is like
having 1 x CM704B zone expander, 1 x CM710B output expander and 1 x CM720B power supply module all in one
and as such each universal expander added to the system will consume the address of the corresponding single
function module.
For example if a universal expander is assigned to address 4, then you cannot assign a CM704B, CM710B or CM720B
module to address 4 and the zones corresponding to module 4 will be provided on the universal expander as per the
table below.
