Dave Walton Posted April 23, 2015 Posted April 23, 2015 Hello all. I'm hoping that you can help me with a choice of detector for a stairway. What I am looking for ideally is something that is quite small and that will vertically emit either a single or curtain beam across a standard (closed) domestic stairway. I have thought about using a standard PIR with a curtain beam lens but would ideally want something a bit smaller / neater with a flatter profile that would make it much less likely to come into contact with anyone (particularly children) when using the stairway. It has to be hard wired and its only purpose would be to trigger the entry / exit timer when coming downstairs (usually in the morning) to allow the keypad to be accessed as it is in the main living room at the bottom of the stairs which is protected by a ceiling mounted PIR programed as timer inhibited. I have used pressure pads in the past but they have proved to be a bit hit and miss after regular use and would much rather avoid them if possible. Thank you in advance, Dave Walton. Quote
datadiffusion Posted April 23, 2015 Posted April 23, 2015 Any PIR with look-down such as a Siemens mounted at the ceiling? Or is the issue that you don't want it triggered from the landing at night? Had no idea anyone used pads after 1980! Quote So, I've decided to take my work back underground.... to stop it falling into the wrong hands
Dave Walton Posted April 23, 2015 Author Posted April 23, 2015 Thanks for the reply. Landing is not an issue as the stairs turn at the top onto an enclosed landing that is not in the view of the stairs. I can't / don't want to mount anything on the ceiling as the wiring has already been run and emerges from the newly plastered wall about half way up the stairs with approximately 1mt of spare cable. Regards, Dave Walton. Quote
antinode Posted April 23, 2015 Posted April 23, 2015 I think you're looking for the Visonic Clip-4N, which is a miniature curtain PIR. It's about 3" tall and an inch or so wide. Should do the job, but they are fiddly to install! Quote Trade Member

norman Posted April 24, 2015 Posted April 24, 2015 I thought they were obsolete, someone on here wanted 100 or so iirc? Quote Nothing is foolproof to a sufficiently talented fool.
datadiffusion Posted April 24, 2015 Posted April 24, 2015 TBH I just assumed still available due to listing on current website - https://www.visonic.com/Products/Wired-Detectors/Clip-ch-4n Quote So, I've decided to take my work back underground.... to stop it falling into the wrong hands
