Disqualification (Important warning)
In order to prevent and signal misalignments caused with the system disarmed or by obstacles
interposed within the action beam of the barriers, for installations envisioning the UNIVERSAL
connection, it is essential to connect the disqualification output (FF clamps) in series to the alarm
relay exchange.
NOTE
The FF output supplies a normally closed relay exchange that opens when the signal level
drops below a minimum level for more than 30 seconds.
In the examples below, the control unit will signal the open zone, both in alarm and in
disqualification.
