Firefighter Telephone System Description

Firefighter telephone systems provide two-way
communications for facilities where radio
communications may not be available or are unreliable.
They are typically used during active firefighting
conditions, during a fire alarm investigation, or during fire
alarm system inspection and test.
System Operation. Connections are made using a
common talk line (party line) that includes a Master
Telephone and up to six remote telephones. Remote
telephones call into the Master by either being taken
off-hook or by being plugged into a telephone jack. The
Master Telephone location receives a ring-in tone with a
visible LED indicator for each telephone circuit. When
the call is received, the operator selects the calling
telephone circuit using the assigned switch control. The
operator at the master location can place the original
telephone circuit on hold and connect to additional
telephone circuits or add them to the talk line.
Master Telephone Operation. The Master Telephone
connects directly into a telephone interface module. A
Push-to-Talk (PTT) switch provides the operator with voice
input control. Each master telephone uses local LED/switch
modules to select telephone circuits and to silence any
subsequent call-ins until selected.
Telephone Circuit Control. A call request causes the
local call-in tone sounder and assigned telephone circuit
LED to pulse quickly. Pushing the calling circuit's switch
silences the local sounder and connects that circuit to the
talk line. Activating the switch again places that circuit on
hold with a hold tone being heard at the remote telephones
and causing that circuit's LED to pulse slowly. Subsequent
pushes toggles from active to hold. Activating a telephone
circuit switch when no call is incoming places a request to
pick up on remote telephones equipped with local LEDs.
Master telephones can be also be connected as an input to
an audio controller module to allow audio system message
broadcasting without using a microphone.

Remote Master Telephones mount in Remote
Annunciator Cabinets and are wired as the only connection
to a telephone circuit. By adding local LED/switch
modules, operation is that of the Master Telephone.
Remote telephones are available cabinet mounted or
for plugging into a dedicated telephone jack. Each hears a
ring tone when a call-in is selected and a hold tone when
placed on hold. When on hold, the remote telephones are
each separated from the talk line.
The Telephone Interface Module provides three
Class B (Class A option is available) telephone circuits,
connection for a master telephone, and a telephone riser
input. One module is supplied when selecting a Master
Telephone. Additional telephone interface modules can be
added as required. Telephone circuit outputs can be
programmed as remote telephones, as a Remote Master,
or for telephone riser operation. Telephone circuits are
supervised for opens, shorts, and overload conditions. The
Master Telephone is supervised for broken cord or
off-hook.
Telephone riser operation can be programmed to
provide a telephone riser output that is used to
interconnect telephone interface modules in different
locations. This output type has ring and hold tones
disabled.
Degraded Mode. If the telephone interface module
loses communications with the host fire alarm control
panel, telephone circuits off-hook are automatically
connected to the talk line allowing any telephone to talk
to another simply by being picked up (or plugged in).
