Section 5: 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.

signal, (b) condition and (c) location of the reporting premises. The general priority reporting
structure is:
