M500CH Control Modules allow a compatible control panel to
switch discrete contacts by code command. The control module	Figure 1. Monitor and control module controls and indicators:
has a status LED that can be latched on or returned to the normal
mode by code command from the panel. Rotary decade switches
are used to set the address of each module.
The control module offers two modes of switching operation.
As shipped, the module is configured for switching an external
power source to notification appliances. The external power
source can be a DC power supply or an audio amplifier (up to
70.7 Vrms). In this mode, the module reports supervision status
of the connected loads to the control panel. Load circuit status is
reported as a NORMAL, OPEN, or SHORTED circuit. Two pairs of		C0554-00
output termination points are available for fault-tolerant wiring.
The second mode of switching operation allows the panel to con-
trol one Form-C (SPDT) set of contacts. Circuit connections to the	Figure 2A. Module mounting with barrier:
contacts are not supervised by the module. This mode is enabled
by breaking two external tabs on the module.
Compatibility Requirements
To insure proper operation, these modules shall be connected to
listed compatible system control panels only.

Mounting M500M and M500CH Devices
M500M and M500CH modules mount directly to 4″ square electri-
cal boxes as shown in Figure 2A. The box must have a minimum
depth of 21⁄8″.
Wiring
NOTE: All wiring must conform to applicable local codes, ordi-
nances and regulations. When using control modules in
nonpower limited applications, the System Sensor CB500		ISOLATED
