Need help!! Any advice would be greatly appreciated! I have a DSC (model #PC1500) home security system. It has 3 door alarm magnets and 2 motion detectors on it. For some strange reason one of the door alarms (magnets) stopped working. The zone light is lit up on the keypad indicating that it isn't on or working. When I open the door the keypad doesn't chime either like it usually does. I have to bypass that zone every time I alarm the system. Does anyone have any idea why it would stop working and what I can do to fix it? The magnets are securely in place and wiring going into the magnet is secure and tight. I'm not sure what to do at this point. I certainly don't feel safe sleeping at night knowing that someone could come in the house and I wouldn't hear them!! I would really appreciate any advice. Thanks!!

My new home will have all doors and windows secured with sensors. My security system comes with one motion sensor but I'm undecided as to where to have it installed. Here's the layout of my house. It's two stories with the upstairs having 3 bedrooms. There is no way to access the upstairs windows without a ladder so the window sensors upstairs are just added protection. The downstairs has a small entry foyer with the livingroom to your right and the stairs to your left. Between them is a hallway that ends up with the garage door on your left and kitchen/dining room on your right. There are two french style patio doors (only one side opens) in the dining room leading to the back yard. In the livingroom there is a door leading to the master bedroom which is the opposite wing from the garage. Every room has a sensored window in the house so the motion detector is extra. I thought about mounting it in the garage but if we come home through the garage we may not have enough time (30 sec) to get from closing the garage to inside the house without having to rush. An added keypad is an option but right now our budget is zero'd out. Any suggestions are welcome
