Eliminating optical feedback
In some installations, two conditions combine to create an
optical feedback loop. Symptoms can include: poor range,
intermittent operation or no operation.
The conditions which sometimes combine to create a feed-
back loop are:
1. Both a sensor and a flasher are located within the same
room.
2. There is some low-level noise or interference on your
system.
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.
