BEFORE INSTALLING

This information is included as a quick reference installation
guide. Refer to the appropriate control panel installation manual
for detailed system information. 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 IM-10 Ten Input Monitor Module is intended for use in an in­telligent alarm system. Each monitor module is intended to inter­face between a control panel and normally open contact devices,
such as pull stations. A common SLC input is used for all mod­ules, and the initiating device loops share a common supervisory
supply and ground. Otherwise, each monitor operates indepen­dently from the others. Each module has its own unique address.

A pair of rotary code switches is used to set the address of the
first module from 01 to 90. The remaining modules are automati­cally assigned to the next nine higher addresses. Provisions are
included for disabling a maximum of two unused modules to re­lease the addresses to be used elsewhere. Each module also has
panel controlled green LED indicators. The panel can cause the
LEDs to blink, latch on, or latch off.

Included:

(6) 1 x 4 Terminal Blocks (2) 11/4″ (32mm) Stand offs

Shipped on Board:

(1) Shunt in Class A/B position
(Shipped in Class B position, remove shunt for Class A)

COMPATIBILITY REQUIREMENTS

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

COMPONENTS

Following are descriptions of the IM-10 mounting frameworks.
There are two mounting options for IM-10 modules:

• Up to six IM-10 modules can be installed on a CH-6 in a
BB-6 cabinet

• One or two IM-10 modules can be installed in a BB-2 cabinet

Chassis

The CH-6 chassis is used to mount IM-10 modules in a BB-6 cabi­net. It accommodates up to six IM-10 modules in a single cabinet
row three modules wide and two modules deep.

3. Module Installation

There are two methods for installing a module in the rear posi

tion of a chassis. Method one is for installation of a rear mod­ule only, when no module will be installed in front of it. Refer
to Figure 5 for instructions. Method two is for installation of
a rear module when another module will be installed in the
chassis position in front of it. Refer to Figures 6a and 6b for
method two. All necessary screws and standoffs are supplied
with the modules.

-

C0885-00

The front IM-10 module positions of each chassis are offset below
the rear IM-10 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 IM-10
modules installed on it. Refer to cabinet installation documents
for dimensions.

The BB-2 cabinet houses one or two IM-10 modules on the inter­nal chassis that is part of the cabinet. Refer to cabinet installation
documents for dimensions.

INSTALLATION STEPS

1. Cabinet Mounting

In a clean, dry area, mount the backbox using the four holes

provided in the back surface of the cabinet (Figure 3).

2. Chassis Installation

The CH-6 chassis is mounted in the BB-6 cabinet. It is shipped

with two self-threading screws, which are used to fasten the
chassis to the back wall of the cabinet (see Figure 4).

Figure 3. Typical mounting hole locations:

Figure 5. Installation of rear module only, method one:

C0237-00

Step 1: Insert the bottom of the IM-10 module down into a rear

slot on the chassis.

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

towards the back of the chassis until it touches the

two standoffs.
Step 3: Align two 4-40 screws with the two standoffs and tighten.
Step 4: Address and wire the modules according to the instruc

tions in this manual.

The steps in Figures 6a and 6b describe and illustrate module in­stallation when the rear chassis position and the position in front
of it will be filled. Front position installation is possible only if the
rear position is filled with another module.

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: Address and wire the modules according to the instruc

tions 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. All wiring to the IM-10 is done via terminal blocks. In order to

properly make electrical connections strip approximately 1/4˝
of insulation from the end of wire, sliding the bare end of the
wire under the clamping plate screw.

3. Set the address on the modules per the job drawing. Use the

rotary code switches to set the address of the first module (be­tween 01 and 90).

In Class B operation, the remaining modules are automati-

cally assigned to the next nine higher addresses. For exam­ple, if the base address switch is set to 28, the next nine
modules will be addressed to 29, 30, 31, 32, 33, 34, 35, 36,
and 37.

The module is shipped in Class B position, remove shunt for

Class A. When operating in Class A, alternate modules are
paired together (+0/+1, +2/+3, +4/+5, +6/+7, +8/+9),
resulting in a total of five modules. For example, if the base
address switch is set to 28, then 30, 32, 34 and 36 will be auto­matically assigned to the modules while 29, 31, 33, 35 and 37
are available to be used for other modules on the SLC. For Class
A and B operation, DO NOT set the lowest address above 90, as
the other modules will be assigned to nonexistent addresses.

4. A shunt is provided to disable a maximum of two unused mod
ules in Class B operation and one unused module in Class A
operation. Modules are disabled from the highest address and
work downward. If two modules are disabled, the lowest eight
addresses will be functional, while the highest two will be dis­abled. For example, in Class B operation, if the shunt for Ad­dress Disable is placed on “two” and the base switch is set to
28, the modules will be assigned to 28, 29, 30, 31, 32, 33, 34

­and 35 while disabling the highest two positions.

NOTE: Place unused shunts on single pin to store on board for

future use.

NOTE: Power must not be applied to the unit when changing

functionality of the shunts.

WIRING NOTES

• Power-limited circuits must employ type FPL, FPLR, or
FPLP cable as required by Article 760 of the NEC.
