hi mike t,welcome to the site,most people dont want or cant afford to get their alarm serviced,they are ignorant on how it works,apart from keying in pin number to turn it on or off,so,when they get a power cut and the standy battery has dead cells,and alarm goes off and they cant switch it off,they panic,the batt has life off 3 or 5 years depends where panel is fitted,so this is why you see so many people being told to replace the battery,the scantronic range tells you when the battery is faulty,as do others,still people doubt our advice,i have been in the trade 40 years now,seen it all,as have the regulars on here,we are not smart arses,we just know what we are on about,very few people have the manners to say thank you for your help,in fact most people dont give any feed back at all,,so,pardon us if we sound or look angry,manners costs nothing,i wish you a long an healthy career in ouy industry mike t
