Why does my system alarm as soon as I open my door?

Be sure the door you are entering is the door you requested a delay be placed on for entry/exit. Typically, only one door is given a delay. If you are now entering through a different door, call us because a delay will have to be added. Also, be sure the system is not being armed in the instant mode which will not allow for any re-entry. There could be a malfunction with the door sensor and service may be required.
