Section 15: DIALER OUTPUTS
This section provides the following information:
• Dialer outputs available
• Telephone line connections
• Telephone line supervision
• Enabling the dialer outputs
• Dialer Operation
Dialer Outputs Available
The VISTA-100 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.
Telephone Line Connections
Connect the main dialer and back-up dialer (if used) outputs to telephone
company lines which provide loop start service using the RJ31X cables supplied.
Do not connect to telephone company lines which provide ground start service.
The 5140DLM backup dialer mounts to the main PCB shield and connects to the
main PCB J3 connector using a ribbon cable (supplied with module) as shown in
the SUMMARY OF CONNECTIONS diagram at the end of this manual.
UL
For Listed Fire Central Station (UL864/NFPA 72) applications, use either a
LORRA alone, the main dialer with the LORRA, or use the main dialer with the
5140DLM Backup Dialer. For Listed fire remote station (UL864/NFPA72)
applications, use the main dialer with the 5140DLM backup dialer. Telephone
line supervision is required for UL Commercial fire alarm systems when a dual
line dialer is used for fire signal transmission.
Telephone Line Supervision
The supervision circuits on both dialer outputs will indicate a fault when the
tip/ring voltage falls below approx. 25 volts (13 volts for the main dialer when the
main PCB blue jumper is cut; 13 volts for the back-up dialer when it's blue jumper
is cut) and when handset current is less than approx. 10 mA.
Faults on the phone lines are displayed as zones 974 (main dialer) and 975
(backup dialer).
1. DO NOT connect both outputs to the same telephone company line.
2. Connect the earth ground screw on the 5140DLM to the earth ground
screw (terminal 30) on the main PCB using 16 AWG wire.
3. Cut the blue jumper when the dialer outputs are connected to telephone
lines which have a telephone company MTU installed.
1. To prevent the risk of shock, disconnect phone lines at telco jack before
servicing the panel.
2. If the communicator is connected to a telephone line inside a PABX, be sure
the PABX has a back-up 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 will result in a
communication failure if power is lost.
