Rated 5 out of 5 by ON GUARD IN MY MAN CAVE! Recently had my former coal house / outside privy demolished and rebuilt as an outside workshop - which my wife has christened with a slate plaque 'Peter's Man Cave' Anyway, it contains a few tools which I wouldn't want to lose that I inherited from my father and the odd power tool, so aside from a formidable door and window with multipoint locking, I thought connecting the 'Cave' to the house alarm - might be a good idea. Hence the purchase of the additional wireless PIR which I've installed. Connection was simplicity itself and I was able to name the PIR 'Man Cave' within the Android Smart phone app that I use to control my system. Works a treat - highly recommended 5 Mar 2016
Rated 5 out of 5 by Additional PIR for Yale Alarm I needed to extend the system I installed and added a new PIR to the system. It's brilliant, it took me longer to put it up on the wall than it took to program it into the system as a new device. Definately recommend this system. 18 Nov 2015

Can I just leave it on the ground corner? what is the difference in terms of coverage area and tamper function etc? Thanks!

Also, why in the control panel the original PIR showed to be IR PIR 1 but this one just had an ID of IR 1?

Hi, We always advise putting the siren high up on an exterior wall for security reasons, however it is tamper proof, so in the event that anyone did tamper with siren it will trigger an alarm. Also any additional item added to the panel will be in another zone, and will not display the same name. Thanks Yale Consumer Team
