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 intelligent,
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 sta-
tus 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-polar-
ized capacitors. There is a panel-controlled LED indicator.
Compatibility Requirements
To ensure proper operation, this module shall be connected to com-
patible 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
1
/
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 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 into a 4
″
x4
″
x2

″
junc-
tion 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 drawings and
appropriate wiring diagrams (Figures 3-4).
