The MI-LZR is a high sensitivity smoke detector analog addressable. The sensitivity of the detector can be up to 50 times greater than that of a conventional optical detector through the use of a laser diode, a special lens and an optical mirror combined with sophisticated algorithms contained in the detector. These detectors are particularly suitable for the protection of computer rooms and all the local "clean", subject to the airflow above the usual conditions (air conditioning). The detectors are certified MI-LZR BOSEC, LPCB and VdS according to EN54-7.
