FireAngel ST-622 Smoke Detector Set + Magnetic Mounting Set

(This text is machine translated) The FireAngel ST-622-BNLT smoke detector is the successor to the widely sold FireAngel ST-620. This high-end reliable smoke detector is equipped with the special THERMOPTEK® technology. As a result, smoke and fire are noticed even faster. The ST-622 has a high-quality finish and a 10-year battery. This great value set also includes 3 XXL magnetic mounting sets. With this you can hang the smoke detectors on your ceiling within a few minutes. New to the ST-622 is the Panasonic 10-year battery and the Sleep Easy function: with this you can switch off the smoke detector for 8 hours (eg if you have a false alarm). Are you replacing an ST-620? You can leave the old base plate hanging, it has remained the same.
