Using low-level radioactive foil, this ionisation detector charges the particles in the smoke chamber. Should smoke enter, it will then disrupt the flow of current and sensors will detect this. That will then trigger the alarm to alert everyone to the emergency.
Installing detectors with a range of different sensor types will ensure you have all-round protection. Plus, by having the same external design as the Apollo Optical Smoke Detector, you won’t sacrifice aesthetics.
