Re: Alarm to connect to CBus (excluding Comfort)

[Kevin Hawkins <yahoogroupskh@xxxxxxxxxxxxxx>]

I have seen mentioned a few times that the C-Bus PIR's are not of a
security design/characteristic .   I think this probably means that they
don't have approriate sensitivity, immunity or trigger characteristics.
Regardless , if you really do mean that you 'dont want another box' you
could use PIR's to simulate an alarm by switching on C-Bus relays that
had an alarm bell attached.  You would have to have timer safeguards on
the relay on time to meet the regulations for bell sounding times and
you would have to consider carefully how to physically set and unset the
system.   Touchscreen (?).    You will need a C-Bus 'smarts' controller
to implement this well - either an approriate touchscreen , HomeGate, or
the PAC maybe... or of course a xAP/HomeVision gateway ;-) and then you
could use your favourite HA software..

I think Schneider also do a product called the 'Minder' but I don't
know much about it - it is a C-Bus linked alarm system IIRC.  Maybe Aus
only  (regs ?) or a past product... not sure.

I really  would recommend a standalone alarm with C-Bus relays outputs
linked into zones , almost any alarm panel could do this.  Right tool
for the job .I know you said no more boxes but it seems better, easier
and cheaper- keypad implementation for example plus the ability to use
standard PIR's if the C-Bus ones prove inappropriate and tamper
protection.   There are many alarm panels with a range of features of
course.. depending on how integrated you would like it to be. I
personally use a Microtech Galaxy alarm panel which I'm very pleased
with. It's integration with C-Bus is via xAP over Ethernet / serial and
some independent relay input/outputs too.
