INSTALLATION AND MAINTENANCE INSTRUCTIONS
BEFORE INSTALLING
This information is included as a quick reference installation guide. Refer to
the appropriate Silent Knight 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 tem-
porarily out of service. Disconnect power to the control panel before installing
the modules.
NOTICE: This manual should be left with the owner/user of this equipment.
GENERAL DESCRIPTION
The SK-Relay is intended for use in intelligent, two-wire systems where the in-
dividual address of each module is selected using the built-in rotary switches.
It allows a compatible control panel to switch discrete contacts by code com-
mand. The relay contains two isolated sets of Form-C contacts, which operate
as a DPDT switch and are rated in accordance with the table in the manual.
Circuit connections to the relay contacts are not supervised by the module.
The module also has a panel controlled LED indicator.
COMPATIBILITY REQUIREMENTS
To ensure proper operation, this module shall be connected to a compatible
Silent Knight system control panel (list available from Silent Knight).

WIRING
NOTE: All wiring must conform to applicable local codes, ordinances, and reg-
ulations. When using control modules in nonpower limited applications, the
CB500 Module Barrier must be used to meet UL requirements for the separa-
tion of power-limited and nonpower-limited terminals and wiring. The barrier
must be inserted into a 4˝ × 4˝ × 21/8˝ junction box, and the control module
must be placed into the barrier and attached to the junction box (Figure 2A).
The power-limited wiring must be placed into the isolated quadrant of the
module barrier (Figure 2B).
1. Install module wiring in accordance with the job drawings and appropri-
ate wiring diagrams.
2. Set the address on the module per job drawings.
3. Secure module to electrical box (supplied by installer), as shown in
Figure 2A.

WARNING
All relay switch contacts are shipped in the standby state (open) state, but may have transferred to the activated (closed) state during shipping. To ensure that
the switch contacts are in their correct state, modules must be made to communicate with the panel before connecting circuits controlled by the module.
