For home smoke detectors, they are usually tested once a week. If the batteries are replaceable they are usually replaced every year.
Check the guide that comes with the detector to be sure. If you don't have it, a quick search of the make and model will get you one.

Most companies say you should test the batteries every three to six months. I do it every three just to be sure.

How do we get the smoke & Fire detector to stop beeping, the cover is off and it is still beeping? There is no battery for these units.

Vacuum the sensor with a crevice tool and then the brush. If it continues, you need to replace it. Please do REPLACE it, smoke detectors saves lives.

The tendency is to leave batteries out or not replace fixed power units. All smoke detectors should be tested monthly and replaced every 10 years.

The was a family of three killed at the weekend in Brampton near where I live. They were in a rented house that had 'no working fire detectors'. That means they had them, but the batteries were dead or not installed.

My alarms go into test mode by themselves about every hour, what can I so to correct the problem?

The detectors have a 9 volt battery back up. The batteries should be replaced every year. If you haven't replaced them recently, that is probably the problem.

Today my fire alarm went off numerous times, no fire or smoke was detected

I would try replacing it. It is probably pretty dirty after 24 years.

My Scorpion Z6 house alarm system, with fire alarms attached, beeped during the night for no apparent reason. All contoller lights were correctly on indicating it is not a battery problem. I think the beep...

I'm not familiar with your system... but, I'd suggest changing any and all batteries, if it happens again. I don't know about your controller lights, but I do know that the battery does not have to get very low in an alarm before it starts giving you an occasional warning chirp.. If your battery or batteries are over a year old, you should change them, anyway. If a new battery (batteries) doesn't fix your problem, you might try vacuuming or blowing some air into the works on the chance you might dislodge some foreign particle that might be causing this. That said, though, I have had to trash fire alarms that did just how you're describing... because, no matter what, I couldn't make them be quiet.

Battery connection on new alarm Light Your Way Smoke and Fire alarm

If the battery will not make a connection, it may not be installed properly. The connector requires firm pressure.

My First Alert instructions say to "press and hold the test button on the cover for 5-20 seconds, or until the alarm sounds".

Alarm beeps every 5 mins. I have changed battery and problem still persists.

Tell me what brand your alarm is and I can help you with the beeping. Usually if you hit # it will silence the beeping for 24 hours. Something you can try is finding your main control box. Its usually located in the garage or in a closet. It is tan and 6 x6. First disconnect the battery inside the control box by jiggling off the black/red leeds. Then unplug the power supply. Wait five minutes. Reconnect the battery and plug in the control box. This is completely powering your system down and then repowering it up-essentially "re booting." If this does not correct the issue, give me the brand and I can further help you.
