Configuration of transmitter for cooperation with an control panel’s phone
communicator requires entering into memory a phone number for which transmitter
is to answer.
Once a phone is picked up via an alarm control panel telephone
communicator , a telephone number is being dialled to make connection. After the
control panel dialled a number to which transmitter is to respond, a transmitter
takes over a phone line namely disconnects a urban line from an control panel and
provides to a phone communicator voltage that simulates an operating phone line.
Next it generates confirmation signal and awaits for data from a control panel –next
DTMF tones generated with communicator are treated as data. After transmitting
adequate number of DTMF signs (16 for ContactID) a transmitter generates Kissoff
signal. Collection of data from control panel finishes at hanging up a phone of a
control panel by phone communicator module. After that transmitter comes back to
standard operation –namely if urban line is operating, it is being connected to an
alarm control panel and awaits for dialling of new number.
If telephone number dialled with communicator is other than number GPRS
module answers, no operation follows and it waits until communicator hangs up a
phone and picks it up again – since picking up a telephone number dialled with a
communicator module is being checked.
All programmable parameters are saved in memory and in case of voltage
drop that are not lost. Supply of power starts the transmitter with saved settings.
