I have an Ei154TL heat detector that won't stop beeping. Why is this, when it's powered by the main as well?

I would check to see if the heater has a battery or not as that is what is most always the problem with detectors beeping for apparently no reason. Even if it is hooked up to main, it just might have a battery. (?) Or google for "heat detector beeping" & check out those links. Good luck! Definitely not something to ignore, I would think.
