Yale B-HSA6010 Alarm Accessory Door/Window Contact, White, 15.2 x 8.8 x 3 cm

This worked ok, no problems

Had a full wireless Yale telephone alert alarm for many years with 11 of these contacts and 8 Pirs around the home.- they really do go the distance.Perhaps not matching the higher end finish/look of SSAIB wired systems on the PIRS, but seem no different to what the older ones did well,including time limited immobility alarming and panic button features and up to 3 telephone number alerting (only if required and then enabled)One of these window/door contacts failed recently on a window and the main unit reported low battery on screen.Normally they would just need the battery replaced.Our Wifi router has never given any issues to the alarm or vice versa, occasionally during a thunderstorm (and rarely) some contacts have stopped signaling for a minute or so.Pressing the button on them and seeing the led to illuminate soon makes them send a signal.This doesn't seem to cause false tamper alerts or siren triggers/false intruder/immobility/tamper/panic dial-outs.The system works on AM frequencies which I was originally thinking might be an interference nightmare, but the band seems good for low power devices and hardly anything else being in that spectrum is a plus.This wireless reed switch had lasted almost 4 years and uses a large flat lithium motherboard type cell, changing it for a new one made no difference so we ordered the full wireless contact replacement above.It was added to the system in 1 minute and came with handy templates,screws plugs or 3m backing adhesive cut out strips for non permanent areas, and of course pre fitted with a new lithium battery that is not on until you remove insulating plastic.Can be mounted horizontally or vertically and the magnet will activate reed from either left or right sides.Overall, a very easy on the bank balance maintenance budget, without wires,monthly contracts or "cloud" based face detection features and a low cost for any parts when they reach end of life.Sometimes, local simple systems can be enough.Everything for the system we have these switches for can still be sourced and replaced on an as needed basis,including smoke alarms/sirens - all with anti tamper features and battery level reporting, right down the range to these small contacts.Be aware that if using the 3m sticky tape option that your anti tamper microswitch at the rear has to press firmly on the surface as if it moves away from it slightly it can trigger the alarm if anti-tamper is turned on at the base.One attempt at break in 3 years ago was stopped by the sirens which probably paid for the alarm.Recommended, even in 2016.

I've bought quite a few of these door & window contacts to upgrade our home system...Yes they really do work, so simple & easy to fit, they can be fixed either using the double sided sticky pads or screwed to your window & door frames (we chose to do the latter). The delivery time is excellent..arrived within a few day's, so you have peace of mind that your property will be secured in know time. I had a few questions to ask the supplier, they came back to me within hours of my email too them, so due to a quick response that's why i ordered with them. Service.... FANTASTIC. The product really is great & does exactely what's it's supposed too do. Hope this is helpful

I needed one of these and I got in contact with Yale Security products and they help me how to connect it on the phone absolutely brilliant very quickly. They solve my problem and I’m back up running now.

My old door sensor broke. Changed the batteries, no good. Not working at all. Purchased a new one off Amazon. It arrived fine. Today having looked at the instructions connected it to the alarm and the door however the alarm was showing a tamper alert. The sensor worked fine but the tamper signal would not clear. I took the new one off and compared it with the old one and discovered the problem. On the tamper switch on the sensor there should b a small spring. It was missing from the new one. Thankfully I was able to get the spring carefully off the old one and fit it to the new one. I refitted the new one and bingo it works and the tamper alarm on the panel has cleared. So glad I kept the old one. Quality control where made slipped up I think. Keep an eye open for this issue. Overall It now works as it should. Great.......Be well all.
