Description
The NX-667 from Interlogix is a crystal shock sensor (White) excellent first line of defense for detecting the possibility of an intrusion due to forced entry. Featuring a unique, advanced micro-controller, the wireless sensor detects vibrations made by an intruder when trying to break or open a window or door before they enter the premises. The sensor also contains two internal reed switches allowing it to be used like a standard door/window contact.
When the sensor detects vibrations, a momentary open circuit is triggered in the shock element of the sensor. The circuit closes again when the vibration stops. The sensor micro-controller “sees” the open/close action as a pulse, causing the sensor to transmit an alarm signal. The sensor has two different detection modes: Gross Attack, which detects a violent blow sufficient to trip the sensor; and Pulse Count, which detects a sufficient number of less violent blows, such as repeated rapping and tapping.
Features
- Shock sensor micro-controller can detect both violent blows, as well as continual tapping or rapping
- DIP switch settings offer convenient adjustment of pulse count, violent blows and the ability to enable and disable the reed switch
- Tamper switch detects potential disablement or damage to the sensor by an intruder
- A wide range of installment options are ideal when either door/window sensors or motion detection devices are not practical
- Two internal reed switches
- Designed for vertical or horizontal mounting
