If the alarm goes off (and it is not a burglary) and we are away on holiday, does the system have a maximum time period before it turns off?

You can adjust the time that the alarm sounds for when setting-up between 1 and 10 mins. Once this has elapsed I believe it resets but I think it will only do it a certain number of times before it switches off.

My door surface and frame surface are not aligned. Can I get spacers?

Without seeing the problem I suspect you could space either the magnet or the sensor to align them, I had a problem but could get around it by putting the sensor on the door and the magnet on the frame which is not usual. The sensor can also detect the magnet from a couple of centimetres which may also be of some help here. Apart from battery changes I have had no problems with them.

will they work outside say on a gate?

These door sensors dont have any weather seals or waterproofing so I wouldnt risk it.

Is this sensor z-wave / would it be compatible with non-Yale z-wave controllers?

No. This only work's with Yale alarm

Hassle free quick installation

We ordered these to extend our system to cover some windows that overlook a flat roof upstairs. Our local neighbourhood news is that burglars have been breaking into properties with flat roof extensions because they quite often do not have cover upstairs and they then only steal from upstairs without triggering alarm systems downstairs. We installed eight of these in about an hour and then linked into system with great ease. We are very pleased that our house is even safer now than it was before. Great system.

Good reliable product

Easy to install and link up to any existing or new system. The battery life is great, haven’t had to change in 2 years. Fit on most doors and windows even if the window/door and the frame aren’t flush.

Easy to Install

Great item - Easily connect to the Yale Alarm. I've used the device on the front door. Clicked learn on the alarm, clicked the button on the device, the two pair up and were good to go. The door opens, the alarm now beeps to make me aware that entry has been gained. I've tried and tested the alarm with the device by arming the alarm and then walking through the door unlocked and the it brings the street to a standstill with the noise.

Take care when replacing battery

The battery supplied with this product (CR2032) lasted less than a week before needing replacement! I did not have one so am using a CR2025. If you have affixed the item & need to change the battery, take care when removing the top section as it is held in by one screw and the plastic prongs are pretty feeble by any judgement. Hold the top on whilst you are undoing the screw otherwise the spring inside will throw the top on the floor and you'll need another unit. Poor design I think.

Ottimo sensore

Semplice da installare e materiali di buona qualità. Ne ho acquistati 3 e tutti sono stati riconosciuti al primo utilizzo dalla base Yale. Una vitina rende semplice l'apertura del dispositivo e la sostituzione della batteria. Ha anche dei distanziali per adattarsi a diversi tipi di porte/finestre.
