Re: Alarm to connect to CBus (excluding Comfort)

[Kevin Hawkins <yahoogroupskh@xxxxxxxxxxxxxx>]

Just thinking on this... The goal with a  C-Bus PIR is usually to
react
quickly to bring on say lighting as someone moves/enters a room.  So
they probably signal as soon as they detect motion.   An alarm PIR
probably delays its signal until it's better confirmed.   If you use a
security panel for PIR occupancy light switching additional delays
happen within the panel before it informs you a zone has opened. These
are to do with linking to a relay output, sending via RS232 or Ethernet
and maybe even a zone delay or multiple knock setting in the specific
zone attributes.   This will always make security panels react less
quickly than native C-Bus when say switching on lights as you enter a
room .   IDRANet - which I also use with their PIR's is really fast at
this - but room occupancy activities are a very key aspect of Idrateks'
Cortex design.
