Okay this isn't a Mac question but there are not sections for buying tips and advice for non-Apple related stuff. This seemed a better fit than community discussion. Anyways I'm looking to replace the smoke detectors in my house. I want smoke detectors that can transmit an alarm wirelessly to a central panel. Which can then set off all the other detectors in the house. The panel should also have a hush button to temporarily disable all alarms for a false alarm. I'm not looking for a monitoring company. I know I've seen these before but it was years ago. My reason for this is last night a fire started in a room with the door shut. Luckily it was at 11PM and I was still awake. So I smelled the smoke and then heard the smoke detector in time to stop it while it was still contained at the source. This made me realize. If everyone was asleep no one would have woken up to that detector. The ones in our rooms and hallway would not have started chirping until the fire was too large to control. Instead everything in the house would have been destroyed by the fire or water from the firemen.
