How often should these detectors be replaced?

Manual states 7 years - In the Professional world this timer starts from date of manufacture.So, Bottom line - do not buy an extra to install at a later date - Unit is like ripening fruit.

The package I have says the detector has a 10 year limited warranty to the original purchaser..

Mine did that a few times and it was one defective unit (garage) that kept triggering the system. They are quite sensitive to any kind of debris. You should also use a vacuum every 6 months and suck out any dust build up of the sensors to help prevent this.

We change batteries probably once a month. Thats the only disappointing thing. Although they are supposed to be good for 3200 times, the motion sensors check you when you walk through the kitchen. I wish they would only come on when you were working at the countertop.

Agree with RIS.Depends on how your old ones are wired, or linked together, if at all.If they are powered by 120 volt house current, and are linked together, the answer would most likely be "no".If your old detectors are battery-operated type, and of the "stand alone" variety, the answer would be "yes".I replaced several of my old "First Alert" battery operated detectors with these, and have had no issues.

I replaced mine when it was not working anymore. Otherwise if it's cleaned well, you don't need to replace it often or at all.

Get a new smoke detector. They get dusty with age and dust sets them off. I hate them

This is an old image. The front now says: Replace by 60 months.These units have a 10 year shelf life and a 5 year use. All of the detectors that SafeHomeProducts has are within a year of manufacture.

I have had four for 3 years. I had to replace one lately. They stay on for about ten (10) minutes, with no activity, and go off. Look around for something moving, another light source, move the sensor and try again. No problem for me, sorry you had it. JCT

Warrenty is one year. There are no separate "parts" covered. I suspect that statement is boilerplate for MTI or Amazon. Life of detector is 5 years, where after it will basically self-destruct after a 30 day warning period that it is going to do so.

This trap uses long lasting LED bulbs. There should be no need to replace the bulbs for a long time.

I change them annually with my smoke detectors and such. Have not had to do it more.

I think you would want something a little more sophisticated with a pancake tube. The Inspector or PRM 8000. This is a great little detector but you need something more sensitive and quicker. You would need to bucket some water then test it over a bit of time. Either of the units mentioned will measure over time.

I seem to have to replace mine every 18 months or so. Really depends on how much tv you watch.

Only if the fuse is is burnt (The device will not work otherwise) this can be usually seen by a visual check of the actual fuse. otherwise an Ohm meter will have to be used across each lead to check for continuity. If you are replacing the detector my advise is to use all new from the box

We just replaced our first one after 4 months. Will probably replace it every 3 to 4 months from now on.

It depends on your specific situation. You should check it at least every six months for excess dirt. Have a professional do it if you are not capable of checking it yourself. Mine lasts about a year with light use in a small house.

Not sure I changed mine after six months as I do the smoke detectors. The batteries and the chime were working well, just my way of doing things.
