General Description of the Tx4 Alarm Transmitter

Image 1. Analog Care Phone / GSM general description
Alarms can be activated with the alarm transmitter Tx4. When the red button is
pressed a red LED lights up on the transmitter for a short period. When the
alarm has been received by Analog Care Phone / GSMCare Phone a signal is sent
back to the alarm transmitter to confirm that the alarm has been activated, then
a green LED lights up briefly.
Tx4 uses dual frequency, which is a new feature that allows it to change
frequency and transmit on another frequency if there is a disruption on the
primary frequency. When an alarm is activated Tx4 first broadcasts on one
frequency. If there is no response from the Care Phone the signal is repeated up
to three times. After which, the Tx4 changes frequency and transmits on the
second frequency, up to four times. This feature provides increased security and
safety for the user. The radio frequencies used are the European-customised
frequency for social alarms 869.2125MHz and 868.3000MHz.
The Tx4 alarm transmitter can automatically send a link test to the Care Phone,
which shows that the Tx4 is working properly and has contact with the Care
Phone. If the link test does not reach the Care Phoneit will send an alarm to a
pre-programmed alarm recipient about the failure of the test alarm from the Tx.
The function is activated in the Care Phone with the help of the handterminal.
The alarm transmitter Tx4 is worn on a bracelet or necklace. The alarm
transmitter is also waterproof (IP67) so that the alarm transmitter can be worn
during a bath or shower. A new feature of the Tx4 is that change of battery is
possible. See section 6.2.
