They use simple dry contact,open the circuit and they create an alarm close
the circuit and the panel see a clear zone...

Simple detector like the bravo series from DSC,or for better performance the
paradox line of detector are pretty good..
but be careful with paradox,they have special type of detector that
communicate digitally with there panel,just look at the spec,most of there
PIR will come in 2 flavour,the normal,compatible with al panel,and the
digital one that talk only to paradox panel..

there is also the C&K line but I don't like to use time in home....the look
of those are not very pleasant,in fact the wife factor is very low on those
PIR but the are not very prone to falsing...
