It is good idea to test anything not used daily on a normal basis. I will reference a few related items, but you can use this for anything.
There are several home safety & security items that you don't regularly use, all of which have the capability of failing due to a lack of maintenance. Most of these only take a few minutes and not much effort.
1-Smoke Detectors: Hopefully you will never need to actually use them, but when you do need them, they better work. We suggest testing all of the detectors in your home once a month.
2-Locks: A commonly used lock should function for a long time with little maintenance. But, one that is used less often could become sticky due to a lack of use. (dust & dirt floating in the air can stick to the lubrication inside causing them to seize. I recommend oiling and tightening the screws on all of you locks and hinges twice a year.
3-Alarm: Most security companies will offer a free service that will allow you to call them and they can check your system remotely for connectivity & low or dead batteries.
