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
The NZM-100 Interface Module is intended for use in addressable two-wire
systems, where the individual address of each module is selected using the
built-in rotary switches. This module allows addressable panels to interface
and monitor two-wire conventional smoke detectors. It transmits the status
(normal, open, or alarm) of one full zone of conventional detectors back to
the control panel. All two-wire detectors being monitored must be UL compat-
ible with this module. The NZM-100 has a panel controlled LED indicator and
can be used to replace an M302 module in existing systems.
COMPATIBILITY REQUIREMENTS
To ensure proper operation, these modules shall be connected to listed com-
patible system control panels only.
