Intermittent sounder problem?

I have a GardTec 300/500 series system Twin 7 segment display unit, and last night the sounder outside was beeping intermittently we were up checking for quite a while, until it seems to have corrected itself, i am wary that it will do it again, have you any ideas what could have caused it ?
