THE FUNCTIONING OF THE SYSTEM
IS AS FOLLOWS :
1) The user at the front door ( disabled person, old person, or other ) pushes the push-
button of the external unit for the assistance request.
2) The led on the front panel switches on and the buzzer makes a "beep".
3) From that time on a RF signal is sent to the internal unit, deactivating simultaneously the
internal receiver module.
4) Once the internal units receive the RF signal it makes the led blinking and start to
beep periodically the buzzer. This step lasts max for 30 sec.
5) During the step 4 the internal personnel has to detect the assistance request and give
the acknowledge: this is done pushing the push-button of the Pupitre, which in this
way stop the beep of the buzzer and switches off the led and simultaneously sends a
RF signal back to the external unit.
6) As soon as the RF signal, sent by the internal unit, is detected by the external unit, as
confirmation of the service request, the led of the external unit start to blink and the
buzzer makes a sequence of "beeps" that lasts 30 sec.
