SK-Control Supervised Control Module
INSTALLATION AND MAINTENANCE INSTRUCTIONS
BEFORE INSTALLING
This information is included as a quick reference installation guide. Refer to
the control panel installation manual for detailed system information. If the
modules will be installed in an existing operational system, inform the opera-
tor and local authority that the system will be temporarily out of service. Dis-
connect power to the control panel before installing the modules.
NOTICE: This manual should be left with the owner/user of this equipment.
GENERAL DESCRIPTION
SK-Control Supervised Control Modules are intended for use in intelligent,
two-wire systems, where the individual address of each module is selected
using the built-in rotary switches. This module is used to switch an external
power supply to notification appliances. It also supervises the wiring to the
connected loads and reports their status to the panel as NORMAL, OPEN, or
SHORT CIRCUIT. The SK-Control has two pairs of output termination points
available for fault-tolerant wiring and a panel-controlled LED indicator.
COMPATIBILITY REQUIREMENTS
To ensure proper operation, this module shall be connected to a compatible
Silent Knight system control panels only (list available from Silent Knight).
MOUNTING
The SK-Control mounts directly to 4-inch square electrical boxes (see Figure
2A). The box must have a minimum depth of 21/8inches. Surface mounted
electrical boxes (SMB500) are available.
WIRING
NOTE: All wiring must conform to applicable local codes, ordinances, and
regulations. When using control modules in nonpower limited applications,
UL requirements for the separation of power-limited and nonpower-limited
terminals and wiring must be met. 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.
IMPORTANT: When using the SK-Control for fire fighter telephone applica-
tions, remove Jumper (J1) and discard. The Jumper is located on the back as
shown in Figure 1B.

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.
