NFRARED MAIN SYSTEM UNIT
3. Optical Feedback Loop
If you have an IR sensor in the same room as a flasher, and you
have some low-level noise or interference, an optical feedback
loop can occur which will interfere with proper operation.
Symptoms can include: poor range, intermittent operation or
no operation.
Solution: You can eliminate optical feedback by replacing any
IRB1 “flooding flasher” with MF1 or MF2 MicroFlashers and
covering all flashers with the supplied IR blocking covers.
There are many methods for reducing interference. Which
solution is best for you depends on your situation. If you
require further assistance contact Niles Technical Support at
1-800-289-4434.
