Does the alarm work when there is power loss?

As I am considerung homey for the house alarm: what
1. if after a break in homey is (within the alarm delay time) destroyed or
2. the power supply destroyed / switched off (and therefor WLAN is enabled)?
Will the (for instance) zwave alarm (solar / battery alarm) work as the signal has been transmitted?
Or what could be the workaround, as homey will be obviously visible in the lobby and prone to be destroyed?

Homey does not have a tamper alarm. I think there would be a way to some sort but it will never be as save a real alarm.
If you can get your hands on a device that is capable of checking of homey still reacts (connecting to it and getting answered, measuring power consumption, seeing if there is a actief wifi connection) and if not sending a signal it would be possible.
At this stage i would not recommend it. Its not yet reliable. Just for playing purpose it would be fun to make. If homey is stable it would be possible but it's never as good as a separately dedicated system!
It wil only make it a bit saver.
Maybe it can communicate with your alarm equipment but don't expect much more than that.
For all the exact reasons you are stating, power loss etc. homey will stop working, completely, it will not send any command's anymore.
There are some workaround if you work for example with the new KaKu security line or Z-Wave is to let the devices talk to each other, not just via homey.
But keep in mind, and just my 2 cents, all wireless protocols can be disturbed (pretty easily).
So if you want a real security system, look at real security systems.
Or accept the risks it brings when using homey/wireless security.
But as @tim1990 also states in his reaction, it is indeed not stable enough yet to use homey as a security device.
