Questions & Answers

Is there a specification for short test?

Asked by: Anonymous
For a fairly quick functional test, you can simply set: High Mode to 10 Low Mode to 1 Time Delay to 30 seconds Cutoff to 1 minute Sens. to Low Setpoint, Fade up, and Fade down, and Photocell to DIS ======================= This will turn lights to full bright with motion, then to 10% brightness after 30 seconds of no motion, then OFF after an additional 1 minute of No Motion. Motion will again turn lights on to full brightness. Photocell can then be adjusted to verify photocell functionality.

About your mounting height recommendation of 40' max., is your device still functional when mounted at 50'? What is the impact on the operation?

Asked by: Besner
The sensor can be mounted at 50 ft but recommended and tested mounted at 40ft. The footprint of the sensing field will increase in size and be less effective. It should still be able to trigger the lights but also should be tested on location for actual coverage and proper operation.
