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 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
M500S Supervised Control Modules are intended for use in intelligent, twowire systems, where the individual address of each module is selected using
the built-in rotary decade switches. This module is used to switch an external
power supply, which can be a DC power supply or an audio amplifier (up
to 80 VRMS), to notification appliances. It also supervises the wiring to the
connected loads and reports their status to the panel as NORMAL, OPEN,
or SHORT CIRCUIT. The M500S has two pairs of output termination points
available for fault-tolerant wiring and a panel-controlled LED indicator. This
module can be used to replace an M500C module that has been configured for
supervised wiring operation.
COMPATIBILITY REQUIREMENTS
To ensure proper operation, these modules shall be connected to listed compatible system control panels only.

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˝×4˝×21/8˝ 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).
C0909-01
MOUNTING
The M500S mounts directly to 4-inch square electrical boxes (see Figure 2A).
The box must have a minimum depth of 21/8 inches. Surface mounted electrical boxes (SMB500) are available from System Sensor.
