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 exist-
ing 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 M502M 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 decade switches. This mod-
ule 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 compatible with this module. The M502M has a
panel controlled LED indicator.
Compatibility Requirements
To ensure proper operation, these modules shall be connected to
listed compatible 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 21 /8″. Flush
mounted electrical boxes (SMB500) are available from System
Sensor.
Wiring
NOTE: All wiring must conform to applicable local codes, ordi-
nances, and regulations. This module is intended for
power-limited wiring only.
1. Install module wiring in accordance with the job drawings and
Figure 1. Controls and indicators:

Three-Year Limited Warranty
System Sensor warrants its enclosed module to be free from defects in ma-
terials and workmanship under normal use and service for a period of
three years from date of manufacture. System Sensor makes no other ex-
press warranty for this module. No agent, representative, dealer, or em-
ployee of the Company has the authority to increase or alter the
obligations or limitations of this Warranty. The Company’s obligation of
this Warranty shall be limited to the repair or replacement of any part of
the module which is found to be defective in materials or workmanship
under normal use and service during the three year period commencing
with the date of manufacture. After phoning System Sensor’s toll free
number 800-SENSOR2 (736-7672) for a Return Authorization number,
send defective units postage prepaid to: System Sensor, Repair Depart-
ment, RA #__________, 3825 Ohio Avenue, St. Charles, IL 60174. Please
include a note describing the malfunction and suspected cause of failure.
The Company shall not be obligated to repair or replace units which are
found to be defective because of damage, unreasonable use, modifica-

quential damages, so the above limitation or exclusion may not apply to
you. This Warranty gives you specific legal rights, and you may also have
other rights which vary from state to state.
