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

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
The SK-Zone Interface Module is 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 allows intelligent panels to interface and
monitor two-wire conventional smoke detectors. It transmits the status (nor-
mal, open, or alarm) of one full zone of conventional detectors back to the
control panel. All two-wire detectors being monitored must be UL compatible
with this module.
coMpatiBility requireMentS
To ensure proper operation, this module shall be connected to a compatible
Silent Knight system control panel only (list available from Silent Knight).
