Connecting The Telephone Lines - ADT FOCUS 200 PLUS Installation And Setup Manual

FOCUS 200 PLUS Installation and Setup Guide
The FOCUS 200 PLUS system will attempt, up to a programmed number of times, to transmit a signal
to the CCC using the built-in dialer. If, after the programmed number of attempts, the signal still has
not been properly accepted by the CCC, and the backup dialer is not enabled, a Comm Fail message
will be displayed on the operating panel. If the backup dialer is enabled, then, after additional
unsuccessful attempts using the backup dialer, for a programmed number of times, the system will
display the Comm Fail message.
If the system detects low voltage on the main telephone lines, it will switch to the backup dialer, if
enabled.
•
The number of dialing attempts is a programmable option. The system is shipped with 10 attempts as
the default.
•
The system will switch to the backup dialer only when it detects a fault (low voltage) on the main
telephone line or when the maximum number of programmed attempts on the main telephone line is
reached.
•
For information about how to program the CCC telco numbers, see the Programming section.
The number of dialing attempts must be programmed for a minimum of 5 and a maximum of 10 attempts

for Commercial fire and UL Burglary alarm systems.
Main Telephone Line Supervision
The supervision circuit on the main dialer will indicate a fault when the tip/ring voltage falls below
approximately 4 volts.
Backup Telephone Line Supervision
The supervision circuit on the backup dialer will indicate a fault when the tip/ring voltage falls below
25 volts (13 if blue jumper is cut) or when the handset current is less than approximately 10mA.
If the communicator is connected to a telephone line inside a PABX, be sure the PABX has a 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 will result in a
communication failure if power is lost .
Service Telephone Jack
The FOCUS 200 PLUS system includes a service telephone jack to provide the installer/serviceman a
quick access to a telephone line. See the Summary of Connections diagram for the location of this jack.

Action
Conduct an electrical test of the line to the CCC or receiving station in accordance with
the requirements for the type of communication method to be employed.
Note: Any limitations or conditions that will affect satisfactory operation must be
immediately brought to the attention of the local telephone company for correction. Any
differences in operation that will affect programmable option selections must be brought
to the attention of the CCC data group for correction before the customized database is
downline-loaded.
