Before Installing
This information is included as a quick reference instal-
lation guide. Refer to the control panel installation man-
ual 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 tempo-
rarily 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 M500R Relay Control 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. It allows a compatible control panel to switch dis-
crete contacts by code command. The relay contains two
isolated sets of Form-C contacts, which operate as a DPDT
switch and are rated in accordance with the table in the
manual. Circuit connections to the relay contacts are not
supervised by the module. The module also has a panel
controlled LED indicator. This module can be used to re-
place an M500C module that has been configured for Form-
C operation.
Compatibility Requirements
To ensure proper operation, these modules shall be con-
nected to listed compatible system control panels only.
Mounting
The M500R mounts directly to 4˝ square electrical boxes
(see Figure 2A). The box must have a minimum depth of
2  / ˝. Surface mounted electrical boxes (SMB500) are avail-
8
able from System Sensor.
Wiring
NOTE: All wiring must conform to applicable local codes,
ordinances, and regulations. When using control modules
in nonpower limited applications, the System Sensor CB500
Module Barrier must be used to meet UL requirements
for the separation of power-limited and nonpower-limited
terminals and wiring. The barrier must be inserted into a

4˝x4˝x2 / ˝ junction box, and the control module must be
