This is a 3-pack with the popular Magnetic Sensor Strips Guard from Swedish Sensative.
With a thickness of less than 3 mm, the Strips Guard can in most cases be mounted between windows/door and its frame – thus becoming invisible. Its self-adhesive backing makes it easy to mount and the custom-made battery* has a lifespan of up to 10 years, as confirmed by Sony’s OTII battery testing tool. For you, it means you can rest assured that Strips Guard will report events for a very long time without you being worried.
Strips Guard is Z-Wave Plus certified and enables communication with other Smart Home devices that support this technology, such as Telldus TellStick ZNet v1 and v2. It monitors your windows and doors and allows you to pair with your smartphone using Telldus Live!.
The package includes:
• 3 sensors
• 3 magnets
• Cleaning tissue (for cleaning the surfaces where the sensor and magnet are to be fitted)

* The battery is not replaceable. When it is worn out, you simply replace the entire sensor and leave the old one to the recycling for electronics.
