Most buildings don't have modern fire alarms - now you can just plug one in.New residential buildings and hotels have very good fire alarms. They have sensors in every room, and a speaker in each suite that tells you what to do. All this technology is required by code, to keep people alive in a fire. If you live in an older building (like I do), you're lucky if there's a big old bell in the hall. That's because rewiring old buildings to bring them up to code is too expensive (tough luck for those who live there).
Signalink Technologies, from Kelowna BC (that's in Canada), has invented a system of sensors that can retrofit a 50 suite apartment building with brand-new alarms in a day. They call it Fire-Link. The system consists of transceiver units (insuite signaling devices or ISDs) that communicate with a network monitoring controller (NMC) using existing power wiring in the building - all you have to do is plug them in.
This is a very elegant solution! As with all code-mandated fire equipment they have had to go through rigorous UL testing, but they say on their web site that the proper listings have been obtained. If you live in a building that needs a fire alarm, give them a ring!
