These detectors will activate your alarm system immediately once the contact is separated from the magnet, i.e. when a door is opened.

The D25 is a 5 screw surface contact complete with a spring tamper switch.  Two nickel screws to govern the reed switch, 2 screws for tamper and 1 spare screw for any custom requirements.
