Ah - I don't know my BSs. Doesn't seem to have made any difference
to the number of false alarms round here, though.

DIY alarms probably aren't fitted in accordance with the standards or
even with regard to correct siting of PIRs etc.

If you want a monitored system and police response having false alarms
is a big no-no now. ISTR three false alarms in a rolling 12 month
period and the police won't bother at all and it puts a black mark
against the alarm company. I think there is also now a requirement for
monitored systems to be able to report to the monitoring station which
sensors have been triggered and in which order and needing at least
two separate but logically connected sensors to be triggered as well.
For example the PIR in a room and a door contact of that room. There
may even be a requirement to be able to listen to the property to
verify the alarm.
