M500DR Audio Control Module
INSTALLATION AND MAINTENANCE INSTRUCTIONS
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
M500DR Audio Control Modules are intended for use in intel-
ligent, two-wire systems, where the individual address of each
module is selected using the built-in rotary switches. This module
is used to select either one of two separate audio signals, then
connect it to a speaker circuit. Wiring to the speaker circuit is
supervised, and status is reported to the panel as NORMAL,
OPEN, or SHORT CIRCUIT. The M500DR has two pairs of output
termination points available for fault-tolerant wiring, and does
not require external non-polarized capacitors. There is a panel-
controlled LED indicator.
Compatibility Requirements
To ensure proper operation, this module shall be connected to
compatible system control panels only.
Mounting
This module mounts directly to 4
″
square electrical boxes (see
Figure 2A). The box must have a minimum depth of 2
/
8
″
. Flush
mounted electrical boxes (SMB500) are available.
Wiring
NOTE:
All wiring must conform to applicable local codes, ordi-
nances and regulations. When using control modules in
nonpower limited applications, the CB500 Module Bar-
rier must be used to meet UL requirements for the sepa-
ration of power-limited and nonpower-limited terminals
and wiring. The barrier must be inserted into a 4
″
x4
″
x2
/
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).
