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.

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).

2. Set the address on the module per job drawings.

3. Secure module to electrical box (supplied by installer),
as shown in Figure 2A.

NOTICE: This manual should be left with the owner/user
of this equipment.

General Description

M500DR Audio Control Modules are intended for use in in-

Figure 1. Controls
and Indicators:

telligent, 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 fault­tolerant wiring, and does not require external non-polarized
capacitors. There is a panel-controlled LED indicator.

Compatibility Requirements

Figure 2A. Module
mounting with
barrier:

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 21/8˝.

Figure 2B. Isolated Quadrant:

Flush mounted electrical boxes (SMB500) are available.

Wiring

NOTE: All wiring must conform to applicable local codes,
ordinances 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

wiring. The barrier must be inserted into a 4˝x 4˝x 21/8˝
junction box, and the control module must be placed into
the barrier and attached to the junction box (Figure 2A).

Figure 4. Typical wiring for speaker supervision and switching, NFPA Style Z:

All relay switch contacts are shipped in the standby state (open) state, but may have transferred to the activated (closed)
state during shipping. To ensure that the switch contacts are in their correct state, modules must be made to communicate
with the panel before connecting circuits controlled by the module.
