Re: PIR, Panic Button, Sounder etc to be used with Comfort System

[Kevin Hawkins <yahoogroupskh@xxxxxxxxxxxxxx>]

PIR's are available that have inbuilt microwave sensors too - such
that
you need both a heat and physical movement to create the alarm condition
- and hence tend to be more reliable.    I use this type myself.

I also saw mentioned on the Idratek list some PIR's that have three
zones and a dual output.  They provide two curtain zones down the wall
lengths (assuming they are in a corner) as well as the central room
zone. Importantly the zones dont overlap so these satisfy the new
regulations for dual sensor sequential confirmed alarms - should you go
for a monitored alarm at any stage.  These could have have HA
applications too in detecting room entry/exit.
