BEFORE INSTALLING

This information is included as a quick reference installation guide. If the
modules will be installed in an existing operational system, inform the op­erator and local authority that the system will be temporarily out of service.
Disconnect the power to the control panel before installing the modules. This
system contains static sensitive components. Always ground yourself with a
proper wrist strap before handling any circuits so that static charges are re­moved from the body. The housing cabinet should be metallic and suitably
grounded.

NOTICE: This manual should be left with the owner/user of this equipment.

GENERAL DESCRIPTION

The ISO-6 Six Fault Isolator Module provides six equivalent circuits that will
allow a portion of the communications loop to continue operating when a
short circuit occurs on that loop. An amber LED indicator will blink in the
noromal state for each of the six inputs and will latch on during a short circuit
condition. The module will automatically restore the communications loop to
normal condition when the short circuit is removed.

CONTENTS INCLUDE:

(6) 1 x 4 Terminal Blocks
(2) 1¼˝ (32mm) Stand offs
(4) Machine Screws
(2) Nuts

COMPATIBILITY REQUIREMENTS

To ensure proper operation, this module shall be connected to a compatible
control panel only.

NOTE: The number of devices that may be installed between fault isolator
modules will vary based on the types of devices on the loop. Contact your
Fire Alarm Panel manufacturer or refer to your device manual for the correct
isolator load ratings of individual devices. When added together, the sum of
all isolator load ratings of the devices between fault isolator modules should
not exceed 1.

COMPONENTS

Following are descriptions of the ISO-6 mounting frameworks. There are two
mounting options for ISO-6 modules:

• Up to six ISO-6 modules can be installed on a CH-6 in a BB-6 cabinet

• One or two ISO-6 modules can be installed in a BB-2 cabinet

Chassis

The CH-6 chassis is used to mount ISO-6 modules in a BB-6 cabinet. It accom­modates up to six ISO-6 modules in a single cabinet row three modules wide
and two modules deep.

C0206-00

The BB-2 cabinet has a built-in chassis that will accommodate one or two
ISO-6 modules.

FIGURE 2: BB-2 CABINET

C0234-06

The front ISO-6 module positions of each chassis are offset below the rear
ISO-6 module positions so that all of the status indicators are visible.

Cabinets

A BB-6 cabinet will house the CH-6 chassis with up to six ISO-6 modules
installed on it.

The BB-2 cabinet houses one or two ISO-6 modules on the internal chassis that
is part of the cabinet. Refer to cabinet installation documents for dimensions.

Step 1: Insert the bottom edge of the ISO-6 module down into a front slot of

the chassis.

Step 2: Carefully swing the upper edge of the board towards the back of the

chassis until it touches the 11/4˝ (31.75mm) standoffs installed on the
rear module.

Step 3: Align two 4-40 screws with the two standoffs and tighten.

Step 4: Wire the modules according to the instructions in this manual.

WIRING

NOTE: All wiring must conform to applicable local codes, ordinances, and
regulations.

1. Install module wiring in accordance with the job drawings and appropri­ate wiring diagrams.

2. Make electrical connections by stripping approximately 1/4˝ (6.35mm) of
insulation from the end of the wire sliding the bare end of the wire under
the clamping plate, and tightening the clamping plate screw.

NOTE: All references to power limited represent “Power Limited (Class 2)”.
