the red LED stays lit.
To leave the alignment mode, push “Select” button of “Master” module for more
than 2 seconds until the buzzer beeps two times.
Response time
Set the response time of the intrusion alarm by using the potential-meter of
“Master” module.
This allows the sensitivity of the barrier to be adapted to its environment. A long
response time reduces the sensibility of the barrier.
