DIALLER OPERATION
DIALLER OPERATION
The PRO-LX Dialler option allows alarms to be transmitted over a
telephone line to a Central Station where appropriate responses can be
made on the basis of information received. If you choose to take advan-
tage of this option then the dialler operations will happen automatically.
There are, however a few things that are important to know such as:
>when does the dialler make calls
>for how long do these calls last
>how the dialler affects other telephone equipment which shares
the same line
>what happens if there is a fault with the telephone line
>The PRO-LX carries the AUSTEL permit number A92/03/0361.
It should be noted that only devices which carry such a permit
may be connected to the Telecom network. Connection of
unauthorised devices may render the user liable to prosecution
under the Telecommunications Act
These topics are now discussed in turn.
Dialler activity
There are basically 3 situations in which the dialler may call the Central
Station:
>report an event such as an intrusion, emergency, arming,
disarming or exclusion
>perform a regular test call to monitor system integrity
>installation and maintenance operation involving exchange of
information between PRO-LX Panel and a remote service
computer
The last situation is not of concern here. The reporting and testing operations
go on automatically and there is no way for you to directly influence or control
them. These are established when the system is installed and should be set
up to fit in with what other things you wish to do with thedialler’s telephone
line.
The reporting rate depends on operational activity. Typically there is one
arming report and one disarming report per day. Intrusions and emergencies
are reported as soon as possible and if the dialler is prevented from transmit-
ting them (for example, because of congestion at the telephone exchange),
then the dialler will keep trying according to a set error recovery plan.
The test call rate may be set from once an hour to one call every 10 days,
or there may no test calls at all. The default is once a week.
