The optical ABUS PREFIRA 5 smoke detector detects smoke particles. If too much smoke enters its sensing chamber, the integrated piezo alarm sounds a loud alarm signal with a volume of at least 85 dB. The detection area of the PREFIRA 5 is up to 60 m². One smoke detector is recommended for each hallway, stairwell, living room, and bedroom. 

In addition, the EN 14604-certified smoke detector impresses with its simple design and a convenient test button that covers almost the entire underside of the PREFIRA 5. 

Product benefits:

• Particularly suitable for bedrooms and living areas: ideal warning detector for bedrooms and children's rooms
• Smoke warning function: the detector detects visible smoke particles in the air and triggers a loud alarm in case of danger – for early warning in the event of fires
• Contamination compensation: thanks to the recalibration of the smoke chamber, the alarm threshold is automatically adjusted to increasing contamination, thus effectively counteracting false alarms caused by dust
• Insect screen: fine-mesh screen that prevents false alarms caused by insects and other small animals entering the smoke chamber
• Translucent LED: for a pleasant lighting effect, the status LED is located under the housing of the warning detector
• Muting: the alarm sound can be temporarily switched off by pressing the test button
• Automatic self-test: silently checks the battery and sensors every 8 seconds
