An off duty Spiderman has suctioned himself to trimp tower! might be a sniper, think the fire department should blast him down with a hose?
Do you see where a battery might go? It sounds like it is hard wired into the house. Check all the other smoke detectors in the house, if one has a better and it's dead, every detector in the house will beep. If the smoke detectors are only hardwired, and have no battery, do yourself and family a favor and buy a few battery powered detectors. In the event of a fire, if the power goes out the detectors will not work. That is why new detectors that are hardwired also have a battery back up.
If it is new, Mom cannot set the alarm until all openings to the house (door, windows) are secured. The alarm will tell mom what is open by either a letter or number, however the alarm company set it up. So if the bedroom window is programmed as 4, the alarm will probably give mom a double beep and then display 4. The double beep tells mom hey, I didn't set myself to alarm because there is a window that isn't locked.
