Central Station Communications
The control panel transmits zone and system status reports to Central Stations via the
public switched telephone network. Two supervised telephone line connections are
made to interface the control panel to the telephone lines. Two optional 7 foot
telephone cords are available for this purpose and can be purchased separately.
The control panel supervises both telephone lines for proper voltage. A delay of two
minutes will occur before a fault in either phone line connection is reported as a trouble.
When a fault is detected, an audible trouble signal will sound, the yellow trouble LED
will blink, the LCD display will indicate the phone line trouble and the trouble
condition will be reported to the Central Station over the remaining operational phone
line.
The control panel comes with line seizure capability provided for both the primary and
secondary telephone line interfaces. Any time that the control panel needs to make a
call to a Central Station, line seizure will disconnect any local premises phones sharing
the same telephone line.
All transmissions to the Central Stations will be sent over the primary phone line. In
the event of noisy phone lines, transmissions will be sent over the backup secondary
phone line.
Two phone numbers must be programmed, the primary Central Station phone number
and the secondary Central Station phone number. All system reports will be
transmitted to the primary Central Station phone number. Reports will automatically be
sent to the secondary Central Station phone number if attempts to transmits to the
primary Central Station phone number are unsuccessful. If 10 total attempts to
communicate are unsuccessful, a Communicator Failure report will be displayed. Note
that as an option, all reports may also be sent to the secondary Central Station phone
number.
