I have the DS12A. If I open the cover I get a message in the AHP Activity Monitor of Sensor Closed both when I take it off and replace it. It registers with my SC1200 as tampered. I want to eliminate my SC1200 panel, it is useless and can't be trusted. I now have a setup through AHP that monitors the sensors and notifies me of any activity except if the sensor is tampered with. I don't understand why the tamper switch on the sensor would send a off command when opened it should send an on command. Is this just something that is missing in AHP and it just defaults to the off command?
