I created an addendum for tenants for them to be familiar how often they are responsible to check the devise as well as test it and change batteries.

It should go to the battery backup when that happens, not set off the alarm.

For our needs it will work good, though it doesn't have as long of a battery use as the Asus, but when the Surface Pro comes out Michael's getting that because of the resolution, he needs for graphics, etc.

Besides smoke alarms, some places now require interlocking smoke detectors that are both battery and hardwired.

I am completing a module that will allow me to send letters to the tenants with very little work.

Do the smoke detectors with your fire system have battery backup?
