Key Features
1. Wireless technology – Thanks to the use of stable radio communication, the switch operates reliably within a radius of up to 30 meters in an open area.
2. Three operating modes – You can set:
- Momentary mode (inching) – each touch triggers an opening signal lasting approximately 1.5 seconds. Perfect for automatic doors or intercoms.
- Maintained mode (toggle) – the device status changes with each touch – ideal for lighting, blinds, electric locks.
- NO (Normally Open) mode – the switch operates until touched again – great for specialized installations.
3. Quick and easy setup – The built-in "Learn" button allows for instant pairing of the transmitter with the receiver. The receiver's ability to remember up to 20 different transmitters is a huge advantage when you need to open the lock from multiple locations.
4. Elegant and durable housing – The button is made of durable metal, resistant to mechanical damage, scratches and dirt.
5. Intelligent power management – The device operates for up to 300 days on a single set of batteries – with daily use. Furthermore, thanks to the receiver's universal power supply, you can easily connect it to most popular systems – without modifying the installation.
6. Safe operation and interference immunity – Thanks to the self-learning system and background calibration (after battery installation), the device adapts to its surroundings, minimizing the risk of false triggering. High sensitivity ensures stable operation even in difficult electromagnetic environments.
7. Compact dimensions and easy installation – The set can be mounted in almost any location – both in the wall and on a flat surface.
