Before Installing
This information is included as a quick reference installa-
tion guide. Refer to the appropriate installation manual for
detailed system information. If the modules will be in-
stalled in an existing operational system, inform the opera-
tor 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.

(Detector loop current is sufficient to ensure operation of one alarmed detector per zone.)
tors. All two-wire detectors being monitored must be UL
compatible with the module.
The module is addressed through the communication line
of intelligent systems. When the module is interrogated, it
transmits the status of one zone of two-wire detectors to an
intelligent control panel. Status conditions are reported as
normal, open, or alarm. The interface module supervises
the zone of detectors and the connection of an external
power supply.
Two rotary decade switches allow setting module addresses
from 00–99. A status LED indicator is provided and is con-
trolled by code command from the control panel. The mod-
ule provides a magnetically activated test switch for testing

Compatibility Requirements
To insure proper operation, this module shall be connected
to compatible intelligent control panels only.Conventional
two-wire smoke detectors must be UL compatible with the
interface module. A list of compatible two-wire convention-
al detectors is below.
Package Contents
The interface module includes the following items:
(1) Two-wire interface module
(1) 3.9K ohm end-of-line resistor (A2143-10)
(1) Off-white cover plate
(1) Screw pack for cover plate
Mounting
The M502M Interface Module mounts directly to 4 inch
square electrical boxes as shown in Figure 2. The box must
have a minimum depth of 2-1/8 inches.
Wiring
NOTE: All wiring must conform to applicable local codes,
ordinances and regulations. When using control
modules in nonpower limited applications, the Sys-
tem Sensor CB500 Module Barrier must be used to
meet UL requirements for the separation of power-
limited and nonpower-limited terminals and wir-
ing. The barrier must be inserted in a 4"x4"x21 /8"
junction box, and the control module must be
placed into the barrier and attached to the junction
box (Figure 2A). The power-limited wiring must be
placed into the isolated quadrant of the module
barrier (Figure 2B).
1. Install module wiring in accordance with the job draw-
ings and appropriate wiring diagrams (Figures 3 – 5).
2. Set the address on the module per job drawings.
3. Secure module to electrical box (supplied by installer),
as shown in Figure 2A.
Testing
The M502M Interface Module can be tested with a test
magnet available from System Sensor (M02-04-01- see Fig-
ure 1). The magnet test checks the module’s electronics
and connections to the control panel. Interfaced two-wire
detectors must be tested independently. Test two-wire de-
tectors per manufacturer’s installation instructions.
