ARD421
Vibration Detector
> The sensitivity level and number of impacts can be configured.
> Alarms when the temperature rises 10°within 30 seconds.
> 2-color LED lights indicate different operating statuses.
> Alarms when the power supply voltage is below 8 V.
> The alarm output status can be set as normally open or closed.
> Detects when the case is tampered with and the device falls.

Technical
Sensor
Piezoelectric ceramics sensor and temperature sensor
Detection Mode
Detection of mechanical vibrations and temperatures
Sensitivity
5 adjustable sensitivity levels
Detection Range
Concrete: Alarms are triggered when vibrations reach a depth of 2 to 8 m from impact drivers or other objects striking the area. For other objects, they have to hit the area 5 times first. Explosions immediately trigger alarms. Steel plate: Alarms are triggered when vibrations reach a depth of 1 to 10 m from impact drivers, and a depth of 1 to 12 m when other objects strike the area at least 5 times. Explosions immediately trigger alarms.
