Hi

The only place I can mount a pir in a lounge is above a radiator if I use a twintec will this reduce the possibility of false alarms

Thanks

It's one of the mitigating things you can do, yes.

 

Models such as the Alarmcom/Siemens IR120 and I assume the Siemens/Vanderbilt e-Line have long claimed to learn and ignore central heating times.

So, I've decided to take my work back underground.... to stop it falling into the wrong hands

It's in the spec, states the IR120 will learn heating patterns during the first 14 days of operation.

There is no need of an RTC for relative timekeeping.

Probably just makes itself less sensitive, so no false alarms but probably reduced catch performance, there is only so much that can be done at a certain price point.

True but £'high double figures' for a PIR on those, relatively expensive.

Agred its always rejection vs sensitivity.

Black mirror setup stopped most fa's.
