M500FP Firephone Control Module
INSTALLATION AND MAINTENANCE INSTRUCTIONS
Before Installing
This information is included as a quick reference installation
guide. 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
M500FP Firephone Control Modules are intended for use in in-
telligent, two-wire systems, where the individual address of each
module is selected using the built-in rotary switches. This module
is used to connect a remote firefighter telephone to a centralized
telephone console. A ringing sound is provided at each off-hook
handset until it is connected to the console. Wiring to individual
telephone jacks and handsets is supervised, and status is re-
ported to the panel as NORMAL, TROUBLE, or TELEPHONE. The
M500FP has two pairs of output termination points available for
fault-tolerant wiring, and includes a panel-controlled LED indica-
tor.
Compatibility Requirements
To ensure proper operation, this module shall be connected to
Listed 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
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
wiring. The barrier must be inserted into a 4

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).
