e) Setting the operating mode of the ‘FHT80TF-2’
In the delivery state the door/window contact sensor ‘FHT80TF-2’ only monitors the internal
contact.
When external contacts are also to be monitored (or only external contacts), then the operating
mode must be adjusted accordingly. The initial operation blinking sequence (begins once the
batteries have been inserted) indicates the current operating mode:
Blinks 3 times Internal contact is monitored
Blinks 4 times External contacts are monitored
Blinks 5 times Internal and external contacts are monitored
To change the operating mode, proceed as follows:
• Keep the ‘TA1’ button on the ‘FHT80TF-2’ door/window contact sensor pressed.
• LED ‘D1’ begins to light up.
Continue to keep the ‘TA1’ button pressed; do not release it!
• The ‘D1’ LED goes out. Now release the ‘TA1’ button.
• The ‘FHT80TF-2’ is now in programming mode.
• Open and close all the windows that are to be monitored several times in order to activate
the magnetic contacts. In this way, you can determine whether the internal and/or external
contact(s) are activated.
• Briefly press the ‘TA1’ button.
• The ‘D1’ LED now blinks to indicate the new operating mode. After synchronising again
(approx. 1 minute) the door/window contact sensor ‘FHT80TF-2’ returns to the normal
operating mode.
