EDC LED does not turn on and does not activate the EDC
output. It is recommended to connect the EDC output to
a trouble input point at the control panel. It is
recommended to check the system any time the EDC
relay has been activated.
Notice!
Connect the EDC to an input circuit and check the system any time the EDC relay is activated.
Notice!
The EDC feature was not investigated by Underwriters Laboratories (UL).
Beam interruption time
The beam interruption time defines the amount of time an intruder must spend in the beam
path before an alarm is generated. For instance, if the interruption time is set at 100 ms, the
detector only generates an alarm if the beams are blocked for more than 100 ms.
Notice!
For UL applications, do not set the interrupt time above 75 ms.
Beam power control
The receiver is at optimal detection level when the transmitter's Beam Power Control setting
matches the installation range. When the Beam Power is not reduced to match shorter
distance, reflection off of nearby surfaces may occur and may cause a missed alarm (no
