BEFORE INSTALLING

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 SK-Mon-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 150 (01 to 90 on panels that support up to 99 addresses).
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.

ShIPPED ON BOARD:

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

INCLUDED:

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

COMPATIBILITY REQUIREMENTS

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

COMPONENTS

The following is a description of the SK-Mon-10 mounting framework:

The IDP-ACB cabinet has a built-in chassis that will accommodate one or two
SK-Mon-10 modules.

FIGURE 1: IDP-ACB CABINET

The front SK-Mon-10 module positions of each chassis are offset below the
rear SK-Mon-10 module positions so that all of the status indicators are visible.
For cabinet dimensions refer to the IDP-ACB instruction manual.

INSTALLATION STEPS

1. Cabinet Mounting
In a clean, dry area, mount the backbox using the four holes pro-

vided in the back surface of the cabinet (Figure 2).

2. Module Installation
There are two methods for installing a module in the rear position

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 3 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 4a and 4b for method two. All necessary screws
and standoffs are supplied with the modules.

FIGURE 3: INSTALLATION OF REAR MODULE ONLY, METhOD ONE

C0237-00

Step 1: Insert the bottom of the SK-Mon-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 instructions in this

manual.
The steps in Figures 4a and 4b 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 a module.

Step 1: Insert the bottom edge of the SK-Mon-10 module down into a rear

slot of the chassis.

chassis until it touches the short standoff attached to the chassis.

Step 1: Insert the bottom edge of the SK-Mon-10 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: Address and 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. All wiring to the SK-Mon-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 (or 01
and 150 for panels that support 159 addresses).

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 (or 150 for panels that support 159
addresses), as the other modules will be assigned to nonexistent addresses.

NOTE: The SK-Mon-10 must have power cycled for shunt changes to take ef­fect.

4. A shunt is provided to disable a maximum of two unused modules 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.

5. A communications loss feature is available on some panels. Upon a com­munication loss, due to a microprocessor failure at the control unit, the
SK-Mon-10 will send a signal to the control unit to activate the notifica­tion device circuits upon initiating of an alarm on the SK-Mon-10. A sin­gle shunt is used to enable (shunt on) or disable (shunt off) this feature
for all modules on the board.

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

wIRING NOTES

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

PROGRAMMING

The modules are programmed as devices in each system according to the pro­gramming instructions in the appropriate FACP manual.
