| Long description | The optical ST622BNLT smoke detector possesses a non-removable fixed 3VDC Panasonic lithium battery with a life of at least 10 years that switches on automatically after installation. The innovative Thermoptek technology makes the detector a combination of an optical smoke detector and a heat detector by means of thermal detection. The detector features Smart Silence technology. In the event of an unwanted alarm, the smoke detector can be paused for up to 10 minutes by pressing the test button. While the alarm is paused, the detector will automatically unpause the alarm if smoke levels do not decrease. | |
