RE: Different false alarms

["Paul" <groups@xxxxxxx>]

Fly spray is very effective in killing them - bloody mess to clear up
afterwards though as there are literally thousands of the buggers. We get
this every year for a few weeks - the surrounding countryside must be a
haven for them. I did some research on them and it turns out they are quite
difficult to get rid of. They get blown in on breezes and tend to fly when
the humidity is high although they$B!G(Bre not good fliers (like before a
thunderstorm - hence thunder flies). Worst thing is they get behind the
glass on all the pictures and even behind the glass on my LCD TV! Not sure
any form of deterrent would work though.



I$B!G(Bve got a lot of PIR$B!G(Bs so don$B!G(Bt want the expense of

I think this will be your issue - I am guessing that although the insects
are very tiny and won$B!G(Bt themselves be $B!F(Brecognised$B!G(B by
their own body
heat,  when they move across a sensor they will mask the various fields
that
the sensor sees and cause an effect of the zones seeing heat movement
across
their view.

Solutions ? Dual tech sensors would avoid this (microwave/IR combined) or
get the crits out of your sensors/house.  Sealing the sensors although you
say they are capable invaders. Sounds like you have an infestation of these
- I assume you have explored the various routes for ridding your home of
these ??  I have seen these $B!F(Bflood your house with ultrasonic
noise$B!G(B
devices that plug in to a socket - supposed to rid your home of spiders etc
- but I remain sceptical.

BTW - altering trip timings on the zones (within Comfort) won$B!G(Bt help
-
altering the sensor sensitivity is done at the sensor - often accompanied
or
only achievable by increasing the $B!F(Bpulse count$B!G(B - but this is
not the way
to go - it will not provide any long term solving of the issue.

On opening up each sensor there were a number of thunder flies in each
(5-10
or so). I wonder if one of these, walking across the sensor is enough
(although they are only 1-2mm long).



Difficult to seal the sensors as well as these bugs are designed to hide in
very tight spaces!

Hmmm ,

It's quite concerning that these are all on separate zones - and
have only just started - makes me think something 'global' has changed -
possibly your little bugs - have a peek in a sensor,  but again this would
normally manifest itself on one zone first. Try dropping the sensitivities
a
little - if this changes things then it points in a certain direction. Does
the weather have any effect on this ??
It is possible that the panel could be causing issues - are the
faults consistently on PIR's or has any other type of zone tripped ever -
assuming you have other types - are the offending zones in any way related
(
if you have any expansion units on the alarm for example).  I am not
familiar enough with Comfort to know if there is a 'double knock' facility
available on each zone - I suspect there is and I think this is what you
want to try setting rather than the perimiter zone approach - although
perhaps this is how Comfort does it.
