Adjusting the beam interruption time
You can adjust the beam interruption time settings according for the detectors intended target using one of the four
selector positions below. The default setting is 50 ms.
D.Q. output (environmental disqualification)
The D.Q. output feature detects when the beam strength is below acceptable levels due to environmental factors such
as heavy rain, snow, or fog. If the beam strength is low for more than 20 seconds due to these conditions, a D.Q.
output signal sends from the receiver. The signal returns to normal when the beam strength is at acceptable levels for
more than two seconds.
Note : D.Q. output is not evaluated by UL.
The D.Q. output signal can be configured for one of the following uses:
•
Separate Output : Sends a signal to the panel that the detector is not working effectively due to weather
conditions.
•
Bypass Alarm : Bypasses the alarm when the D.Q. output is triggered by adverse weather conditions.
You can configure either option with the following jumper pin settings on interface board of the Receiver:
