Smoke detectors won't stop beeping. Have replaced units and batteries. HELP!!!?
I have 4 hard wired Firex smoke detectors. The one upstairs will randomly beep (no set day or time). Beeps once, stops for about 10 seconds, beeps again, stops for about 10 seconds and proceeds to do this 2 more times, for a total of 4 times. Then, it stops. I replaced all of the batteries, still did it. I replaced all of the units and it still does it. Could there be an interruption in the current? My neighbor (and a contractor friend of his) suggested taking a hair dryer and drying the connections, in case there is condensation or some type of moisture. I did that and it still beeps. I called Firex and they were no help. I called the builder (townhome is 5 years old) and they told me to replace thie units, which I did. I am at a loss and so baffled!!!!!!!!!!!!!!!!! Is anyone able to offer me some guidance? Thank you, in advance, for your help!

OK, Here's the real thing.....If you live in a condo or an apartment, then your detectors are tied into a panel somewhere in the building with all the other condos. The panel will show trouble if there is something wrong, and call the fire department (with the help of a dialer located right next to the panel) should a smoke alarm be activated.
These smoke alarms are not your standard 120v alarms that you buy at home depot. They are actually 24v alarms that get it's power from the panel. That's why if you shut off all the breakers in your unit, the alarms are still active. That's also why your 120v detector keeps beeping, it's only getting 24v which is not enough to operate the detector.
So what you need to do is find out what alarm company your condo association uses (it will have a label on the box) and call them for replacements that will work with that system.
By the way, there is probably at least one smoke detector that looks different from the others and that's because it's a heat sensor. So make sure you replace a smoke alarm with a smoke alarm, and a heat sensor with a heat sensor.
You can verify this if you'd like by taking a volt meter to the circuit and you'll be getting 24v even if you shut off all power to your unit.
