The silver-coloured smoke alarm is an optical smoke detector which reacts speedily to all forms of visible smoke, including slow growing fires.
This optical smoke alarm is "intelligent". It is micro processor programmed so that the alarm, daily, checks and adjusts its own sensitivity for optimal smoke detection.
It features an acoustic and a visual warning alarm, of course in case of fire, as well as when the battery needs changing, when it needs cleaning or in the event of a malfunction.
The red button is used to test and to reduce the sensitivity for 10 minutes in order to avoid false alarms, for example, smoke arising from a cold fire place.
With the classical Jacob Jensen design it is a pleasure to protect your home.
1 x 9v battery included.

Battery type 9 V - Alkaline recommended - approx. lifetime of one year. Normal function of the smoke alarm is at least 10 days from the first low battery signal. Alarm signal min. 85 dBA. The alarm is active as long as three is smoke in the detector. When there is no longer smoke in the detector, the smoke alarm automatically reverts to stand-by. Smoke detection every eighth second. Pause function by pressing red test button, which reduces the sensitivity to 50% for 10 minutes in order to avoid a false alarm, for example smoke arising from a cold stove or while cooking in the kitchen. Reverts to normal operation (100% sensitivity) after 10 minutes. Working area from +4ºC to +40ºC / humidity 10 - 90%. | Visual indication: | Normal operation: one flash every eighth second. Reduced sensitivity (pause function): two flashes every eighth second. Smoke detection: a continuous flash. | Acoustic indication: | One short beep every minute indicates a low battery. After replacement of battery the micro-processor checks every function and reply with a longer signal when checking and calibration of the sensitivity is done.
