Section 5: Central Station Communications - POTS Transmission
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 opera-
tional 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 commu-
nicate are unsuccessful, a Communicator Failure report will be displayed.
