Installation Instructions

Model TZC-8B
Telephone Zone Card

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/Desigo Fire Safety Modular/Cerberus PRO Modular 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 Tele-phone 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.

The LEDs follow the reset switch and their functions are defined as follows:

• POWER (Green) Normally ON. When illuminated, indicates that power for the TZC-8B is applied to the card.
• CARD FAIL (Yellow) Normally OFF. When illuminated, indicates that the card microprocessor has failed.
• CAN FAIL (Yellow) Normally OFF. When illuminated, indicates that the CAN communication with the TZC-8B has terminated.
• GND FAULT (Yellow) Normally OFF. When illuminated, indicates that the TZC-8B has detected either a negative or positive ground fault on its field wiring.
• ZONE 1 ACTIVE (Red) Normally OFF. When illuminated, indicates that Zone 1 is active.
• TROUBLE (Yellow) Normally OFF. When illuminated, indicates that the TZC-8B has detected a trouble on Zone 1 (open circuit or short circuit).
• ZONE 8 ACTIVE (Red) Normally OFF. When illuminated, indicates that Zone 8 is active.
• TROUBLE (Yellow) Normally OFF. When illuminated, indicates that the TZC-8B has detected a trouble on Zone 8 (open circuit or short circuit).

PRE-INSTALLATION

CAN Network Address Switch: Set the two-digit CAN network address for the TZC- 8B using the two rotary dial switches located near the bottom of the front panel.(Refer to Figure 1 for the location of the switches.) The address selected at the front panel of the TZC-8B must be the same as the address selected in the Zeus program-ming tool. To set the address, turn the pointers on both of the two dials to the numbers for the selected address. For example, if the address is 12, set the pointer for the TENS dial to “1” and set the pointer for the ONES dial to “2”. Allowable addresses are from 01 to 99 (leading zeros must be used).

WIRING

Remove all system power before installation, first battery then AC. (To power up, connect the AC first, then the battery.)
All field wiring to the TZC-8B is connected to the terminal blocks of the CC-5 card cage slot in which it is installed (refer to Figure 2).
The top terminals (1 through 8 and 9 through 16) are connected to telephone zones 1 through 8. Terminate all unused outputs with an EOL resistor, as shown in Figure 2.
Of all the bottom terminals (17 through 24), only terminals 17 and 18 are used for +24V connections.
The screw terminals can accommodate one 12-18 AWG.

NOTES

1. All wiring must be in accordance with Article 760 of NEC or local building codes.

2. All output circuits are power limited to NFPA 70 per NEC 760.

3. Electrical Ratings:
   Output Zone Supervisory: 35mA max @ 24VDC

4. A maximum of 10 phones can be simultaneously connected throughout the system.

5. An unlimited number of jacks can be connected to each zone on the TZC-8B.

6. 100Ω max per zone.

7. Use twisted pair or shielded twisted pair.

8. Terminate shield at TZC-8B only.

9. Positive or negative ground fault detected at <10K ohms for terminals 1-16.

INSTALLATION

The TZC-8B plugs perpendicularly into one slot in the CC-5 card-cage via two 96-pin DIN connectors and can occupy any slot in the card cage.

Insert the TZC-8B card into the card guides rightside up (lettering on the front panel is legible).
Slide the card in until the card edge connectors contact the receptacles on the motherboard.
Verify that the DIN connectors of the card and the card-cage aligned properly. The card can only plug in one direction to the card cage, if it does not align, DO NOT FORCE the card.
Place thumbs on the front panel adjacent to the captive screws and gently apply even pressure on the card until the connectors seat in the receptacles on the motherboard.
Secure with the captive screws.
Power up the system and verify that the TZC-8B power LED turns ON.

To Connect External Wiring Loosen the screw of the terminal by turning it counterclockwise.
Insert the wire into the side of the terminal block
Tighten the screw of the terminal block by turning it clockwise.
