yes it has been beeping for the last twelve months since I moved in the lady I bought house from said it had always been that way but she never bothered because she reckoned that it alerted people that the house was alarmed but it drives u mad if window open at night just constant beep beep
thanks for your reply but I cant see any make on box but it does not appear to have any battery inside as far as I can see and I think it does resemble a bar of soap
