I inherited a Simon XT system as part of a house purchase and enlisted Brinks Home Security to monitor the system. Recently my back door sensor has been sending false alarms when the system is armed. The senor is drilled into the door itself and, when removed, looks like a sensor on the end of a long battery.
Is this a battery related issue? Is there something else I should be troubleshooting? I hate to keep paying for a monitoring system if I can't arm it without false alarms.
