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 re-
moved from the body. The module housing should also be grounded.
NOTICE: This manual should be left with the owner/user of this equipment.
GENERAL DESCRIPTION
The SK-Zone-6 Six Zone Interface Module is intended for use in an intelli-
gent alarm system. Each module provides an interface between the intelligent
alarm system and a conventional alarm system loop. A common SLC input is
used for all modules, and the initiating device loops share a common super-
visory 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 154. The remaining modules are automatically assigned to the next
five higher addresses. Provisions are included for disabling a maximum of two
unused modules to release the addresses to be used elsewhere. Each mod-
ule also has panel controlled bicolor LED indicators. The panel can cause the
LEDs to blink, latch on, or latch off.
Included:
(5) 1 x 4 Terminal Blocks (2) 1.25" Stand offs (3) Shunts
(4) Machine Screws (2) Nuts (1) Long Power Supply Jumper
(6) 3.9k Ohm End of Line Resistors
C0202-00
Shipped on Board:
(2) Shunts in Class A/B position
(Shipped in Class B position, remove shunts for Class A)
COMPATIBILITY REQUIREMENTS
To ensure proper operation, this module shall be connected to a compatible
Silent Knight system control panel (list available from Silent Knight).
A list of compatible two-wire System Sensor Smoke detectors for use with the
SK-Zone-6 is available on the System Sensor website at systemsensor.com.
COMPONENTS
The following is a description of the SK-Zone-6 mounting framework:
• One or two SK-Zone-6 modules can be installed in an IDP-ACB cabinet

The IDP-ACB cabinet has a built-in chassis that will accommodate one or two
SK-Zone-6 modules. For cabinet dimensions refer to the IDP-ACB instruction
manual.
The front SK-Zone-6 module positions of each chassis are offset below the
rear SK-Zone-6 module positions so that all of the status indicators are visible.
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 2).
