The NX model is still packed with many of the innovative new features
to blow away the competition, with the only notable exception being that
it’s not compatible with the NTX Receiver. Like all three of the new
alarms, the NX uses 2 x AA batteries to make it more user-friendly, but
to also help offer amazing battery life. It also benefits from our
top-secret new D-Tec Sensing System. This eliminates the need for reed
switches, which are usually the first part to break if the alarm is
dropped or knocked. This means all N Series alarms are ultra durable.
