A warning light has come on our alarm keypad saying 'battery low'. We took off the cover last night and we dont have a clue what the battery even looks like! Our problem is this - we bought the house secondhand and we cant contact the previous owner - there is no alarm company name on the box outside and nothing on the keypad either. Its an aritech alarm - we need to get an engineer out I guess but my sister reckons an alarm co wont come out unless they have supplied the alarm! Anybody have any ideas on what we should do? or even who we should ring? we live in Drogheda.
