When designing this smoke alarm, the explicit aim was to avoid operating controls that would spoil its appearance. The device’s necessary functions were meant to be integrated in perfect harmony with its form. As a result, the PX-1 smoke alarm has a particularly user-friendly test-stop key which, in fact, takes up the entire lower area of the casing that can be colour coated. PX-1 is equipped with the latest sensor technology and can, as it were, “sense” when its surface is touched. This triggers the test signals or, in alarm mode, deactivates the beeper. Featuring a 12-year guarantee, the PX-1 quality speaks for itself.
