The Interlogix NX-458 is a recessed door and window contact designed for use with Interlogix wireless security systems. It communicates at a wireless frequency of 319.5 MHz, which is compatible with Qolsys IQ2 Panels with a legacy Interlogix daughtercard. The sensor possesses a long battery life, and it is a great selection for Interlogix users who are looking for a recessed sensor option. Recessed sensors offer an invisible solution for door and window protection. No bulky sensors mounted to the frame of the door or window like a surface mount contact.
As a door and window contact, the Interlogix NX-458 functions using a sensor with a reed switch and a magnet. When the door or window is opened, the magnet will separate from the sensor. The reed switch will open the circuit and report a fault signal to the alarm system, letting it know that the door or window is open. Depending on how the zone's response type is configured, it will report the fault as an alarm when the system is armed.
Most residential alarm owners really appreciate the hidden profile of the NX-458, and they are pleased to not have a visible sensor on their door or window. The downside to recessed sensor installation is that holes must be drilled into the door or window and the frame. The sensor and magnet will then be inserted into these two holes so that they are taken out of sight. This may void the warranty on certain types of newly installed doors and windows. Be sure to verify warranty information before drilling any holes.
For optimal performance, the NX-458 should ideally be installed within 100 feet of the alarm system. We recommend walk testing the sensor after installing it to make sure that it has been programmed properly. Simply open the door/window and ensure that the panel is showing the fault in a disarmed state.
