Hi all. My alarm system problem started from low battery to lid tamper... All have been fixed thanks to this forum. Thank you very much. But now I am stuck. It's wireless. Front door magnet was unscrewed due to so many failures of battery replacing attempts, trying to figure out.... When screwed back, when it's just placed to the position, the transmitter flashed once or twice. But then stopped. When I try to set the alarm, it says Front Door Z09 OPEN. When opening, there are no flashes on the transmitter. When I tried to open the transmitter, it set the alarm off, so it seems working. Only it doesn't recognize the magnet. What should I do now? Buy a new transmitter and magnet set? I am going on holiday in a few days so need to sort this out pretty quickly. Thanks for your advice in advance. 22
