BEFORE INSTALLING
This information is included as a quick reference installation guide. Refer to the con-
trol 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 temporarily 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 M502MA 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 (normal, open, or alarm) of one
full zone of conventional detectors back to the control panel. All two-wire detectors
being monitored must be ULC compatible with this module. The M502MA has a
panel controlled LED indicator. M502MA is capable of handling more than one de-
tector in alarm condition.
COMPATIBILITY REQUIREMENTS
To ensure proper operation, this module shall be connected to a compatible
System Sensor system control panel only (list available from System Sensor).
MOUNTING
The M502MA mounts directly to 4-inch square electrical boxes. (See Figure 2.) The
box must have a minimum depth of 2.125 inches. Surface mounted electrical boxes
(SMB500) are available from System Sensor.
