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 M502M Interface Module is intended for use in intelligent, two-wire sys-
tems, where the individual address of each module is selected using the built-
in rotary decade switches. This module allows intelligent 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 M502M has a panel controlled LED indicator.
COMPATIBILITY REQUIREMENTS
To ensure proper operation, these modules shall be connected to listed com-
patible system control panels only.
MOUNTING
The M502M mounts directly to 4˝ square electrical boxes. (See Figure 2A.).
The box must have a minimum depth of 2.125˝. Surface mounted electrical
boxes (SMB500) are available from System Sensor.
WIRING
NOTE: All wiring must conform to applicable local
codes, ordinances, and regulations. This module is
intended for power-limited wiring only.
1. Install module wiring in accordance with the job
drawings and appropriate 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.
