Telephone Line Connections; Main Dialer Connections - Honeywell VISTA-128FBPN Installation And Setup Manual

Telephone Line Connections

The VISTA-128FBPN provides one main built-in dialer for communication to the central station and one optional
5140DLM Backup Dialer, both supervised for voltage and current on the phone lines.
Do not connect the system to telephone lines that require ground start service.
For Listed fire central station (UL864/NFPA 72) applications, use communications device
main dialer with the
U L
For listed fire remote station (UL864/NFPA 72) applications, use the main dialer with the 5140DLM.
Telephone line supervision is required for commercial fire alarm systems.

Main Dialer Connections

To connect the main dialer, refer to the Summary of Connections diagram and perform the following steps:
Step Action
1 Connect the main dialer to the telephone company lines using the RJ31X cable supplied.
2 If the dialer output is connected to telephone lines that have a telephone company MTU installed, cut the
blue jumper (W6).
Installing the 5140DLM Backup Dialer
Do not connect the main dialer and the backup dialer to the same telephone company line.
To install the 5140DLM, refer to the Summary of Connections diagram and perform the following steps:
Step Action
1 Mount the 5140DLM to the main PC board shield.
2 Connect the backup dialer to the telephone company lines using the RJ31X cable supplied.
3 Connect the backup dialer to the J3 connector on the main PC board using the ribbon cable (supplied with
the module).
4 Connect the earth ground screw on the 5140DLM to the earth ground terminal (30) on the main PC board
using 16AWG wire.
5 If the dialer output is connected to telephone lines that have a telephone company MTU installed, cut the
blue jumper on the 5140DLM PC board.
Telephone Line Supervision
If the tip/ring voltage falls below approximately 25 volts (13 volts if the blue jumper is cut) or the handset current is less
than approximately 10mA, the supervision circuits for the dialer output will indicate a fault condition. Faults on the
phone lines are displayed as zones 974 (main dialer) and 975 (backup dialer).
•
To prevent risk of shock, disconnect the phone lines at the telco jack before servicing the panel.
•
If the communicator is connected to a telephone line inside a PABX, be sure the PABX has backup power
supply that can support the PABX for 24 hours (central station usage) or 60 hours (remote station usage).

Many PABXs are not power-backed up, and connection to such a PABX results in a communication failure if
power is lost.
Zone 974 (Primary Dialer Supervision) must be enabled in order for the backup dialer (or communications
device, if used) to communicate in the event that the primary dialer fails.
If a communications device is used as the primary dialer, then its supervisory zone must be enabled (e.g. 8XX,
where XX is the device address of the communications device.
U L
The telephone line inputs have overvoltage protection in accordance with UL1459.
