M500FP Firephone 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
M500FP Firephone Control Modules are intended for use in intelli-
gent, two-wire systems, where the individual address of each mod-
ule is selected using the built-in rotary switches. This module is
used to connect a remote firefighter telephone to a centralized tele-
phone console. A ringing sound is provided at each off-hook hand-
set until it is connected to the console. Wiring to individual
telephone jacks and handsets is supervised, and status is reported
to the panel as NORMAL, TROUBLE, or TELEPHONE. The M500FP
has two pairs of output termination points available for fault-toler-
ant wiring, and includes a panel-controlled LED indicator.
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 21 /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″x21 /8″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).
