Spyman48 Posted October 13, 2015 Share Posted October 13, 2015 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 Link to comment https://www.thesecurityinstaller.co.uk/community/topic/39211-pir/ Share on other sites More sharing options...
datadiffusion Posted October 13, 2015 Share Posted October 13, 2015 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 Link to comment https://www.thesecurityinstaller.co.uk/community/topic/39211-pir/#findComment-432358 Share on other sites More sharing options...

datadiffusion Posted October 13, 2015 Share Posted October 13, 2015 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.

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. amealing@texe.com Head of Industry Affairs Visit Our Website Texecom Link to comment https://www.thesecurityinstaller.co.uk/community/topic/39211-pir/#findComment-432362 Share on other sites More sharing options...
datadiffusion Posted October 13, 2015 Share Posted October 13, 2015 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.
