Overview
ASD 531
The ASD 531 is small, yet extremely powerful.
As with the two larger models in the ASD range, it is also equipped with the tried-and-tested HD detector with LVSC (large-volume smoke chamber). Its outstanding sensitivity ensures high levels of safety, combined with an impressively long service life. The ASD 531 ignores individual disruptive factors effectively thanks to its patented lint filter.
The ASD 531 is the perfect choice for anyone wanting to put a smaller system into operation quickly and easily without the need for extra training. Configuration is made directly on the device using BasiConfig in just three simple steps without the need for a PC.
Operation of the compact device is just as easy. With the ASD 531, you can monitor your rooms and premises reliably and precisely with a minimum of effort and exceptional cost efficiency.
