5. Registering the TX 4020 Smart transmitter
To register the TX 4020 Smart transmitter code in the alarm center, follow the procedure below:
Insert the LITHIUM 3 Vcc - CR 2032 battery, then enter the command to register the wireless device in the alarm center
that will be used (Check the procedure in the alarm center manual).Then press the CH1 key for approximately 2s, observing
whether the LED lights up, if the LED lights up it indicates that transmission has occurred, if it does not light up, check the
battery and repeat the procedure.
Note:
to register using the CH1 key, the transmitter must not be connected to the wired sensor. If the transmitter is already
connected to a wired sensor, simply trigger the sensor and observe whether the transmitter LED lights up, if the LED lights
up it indicates that there has been a transmission, if it does not light up, check the connection between the sensor and the
transmitter or check the battery and repeat the procedure.
» Low battery sensor: the TX 4020 Smart has a battery level meter, which measures the voltage and noties you of the
best time to change it. If the alarm center is Intelbras, the sensor low battery warning will be indicated on the product
panel. The sensor sends a low battery warning in both OOK and FSK modulations.
6. TX 4020 Smart transmitter supervision adjustment
The TX 4020 Smart transmitter allows you to select between supervised (FSK) and unsupervised (OOK) modes. To switch
between supervision modes, simply remove the battery from the transmitter, open the OOK/FSK jumper indicated on the
board (and then replace the battery); once this is done, the transmitter will operate in supervised mode (FSK). Changing
from supervised mode (FSK) to unsupervised mode (OOK) is also simple, just remove the battery from the transmitter, close
the OOK/FSK jumper terminals again and replace the battery, once this is done the transmitter will return to operating in
the unsupervised mode (OOK). Factory default: unattended (OOK).
In FSK modulation, the transmitter transmits opening and closing and periodically performs supervision.
