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
