If you don't want to have to use a reed switch magnet type of recessed contact then the TANE 22TCWH is a nice solution. It is a roller ball type switch, 3/4" in diameter, which means that the contact can be recessed into just the door or window side and when either are open the roller ball pops out opening the circuit. This will initiate an alarm condition in your security panel. These come with a spacer and screws. |
