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.
