I want to open the alarm power box to look at the battery and charger, and I know there will be a tamper switch. When the alarm sounds do I just enter my master code and it will silence and all will be well? Or is there a lower level code needed (eg; an engineering code)?
My panel is a Median manufactured by Castle Care-Tech Ltd. The manual is not clear on what will happen, and I want to check before I spoil my neighbours Saturday afternoon! Thanks
