Telephone Zone Card
Installation Instructions
Model TZC-8B
INTRODUCTION
The Model TZC-8B Telephone Zone Card from Siemens
Industry, Inc., provides a way for emergency response
personnel located throughout a building to speak with one
another during emergency situations. The card is located in
any FireFinder-XLS enclosure and is connected to jacks or Fire
Fighter’s Telephone Stations located throughout the building.
Portable phones (Models PFT and PFT-P) that plug into
these jacks or Fire Fighter’s Telephone Stations (Model FTS)
can communicate to the Model FMT Fireman’s Master
Telephone located at the main enclosure or to telephones
connected to the system.
OPERATION
Each TZC-8B module provides eight telephone zones. The
TZC-8B module connects to the emergency telephones or
telephone jacks located throughout a building through the
eight telephone zones. In addition, it is also connected to
the phone riser and to the CAN bus which the system uses
to control the TZC-8B.
In normal operation, the TZC-8B monitors the inputs of the
eight zones to detect if one of the connected phones is off
hook or “jacked in”
. When this is detected, the TZC-8B
transmits a message to the system via the CAN bus. The
system indicates the call on the front panel. Depending on
operator action, a message is sent back to the TZC-8B to
connect the zone through to the phone riser.
All the TZC-8B zone circuits are supervised for Class B
(Style Y) use only.
Controls and Indicators
The front panel of the TZC-8B contains one reset switch, 20
LEDs, and two CAN address switches as shown in Figure 1.
A reset switch is located on the top of the front panel.
Pushing the reset switch re-initializes the TZC-8B operation.
