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-Control-6 Six Circuit Supervised Control Module is intended for use
in an intelligent alarm system. Each module is intended for switching applications involving AC, or DC which require wiring supervision. A common
SLC input is used for all modules. Each module has its own address. A pair
of rotary code switches is used to set the address of the first module from 01
to 154. The remaining modules are automatically assigned to the next five
higher addresses. Provisions are included for disabling a maximum of three
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. In order to synchronize strobes, horn/strobes,
and speaker/strobes, a SYNC-1 accessory card (sold separately) must be used
with the SK-Control-6. See the SYNC-1 installation manual for details on how
to install.
Each module has terminals for connection to an external supply circuit for
powering devices on its NAC. Each supply must be power limited and its voltage/current limits must be at or below those specified. There is a short circuit
protection monitor for each module. This is provided to protect the external
power supply against short circuit conditions on the NAC.

NOTICE TO USERS, INSTALLERS, AUTHORITIES HAVING JURISDICTION, AND OTHER INVOLVED PARTIES
This product incorporates field-programmable software. In order for the product to comply with requirements in the Standard for Control
Units and Accessories for Fire Alarm Systems, UL 864, certain programming features or options must be limited to specific values or not used
at all as indicated below.
Program Feature or Option
Permitted in
UL 864 (Y/N)
Disabling short circuit protection

shared by multiple NACs
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-Control-6 mounting framework:
One or two SK-Control-6 modules can be installed in a IDP-ACB cabinet.•
The IDP-ACB cabinet has a built-in chassis that will accommodate one or two
SK-Control-6 modules.

can be disabled only when a power supply is not shared by
multiple NACs.
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
C0234-03
The front SK-Control-6 module positions of each chassis are offset below the
rear SK-Control-6 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 provided in the
back surface of the cabinet (Figure 3).
FIGURE 2: TYPICAL MOUNTING HOLE LOCATIONS
C0237-00
Step 1: Insert the bottom of the SK-Control-6 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.
