PIR Problem: False Alarms When
Coming Home on a Rainy Day
If a customer sometimes comes in and gets an
alarm from a PIR that should be a follower, check
out this possibility. If the door sensor is set to
slow
(Fn#516) and the PIR is aimed directly at the
door, someone could open the door fast enough
to set off the PIR before the door’s 400
msec
delay is up. This means that the PIR hasn’t moved
to the follower status and generates an immediate
alarm. Changing
Fn#516 to fast (“0”) should put a
stop to this.
