Elro Fire Prevention Set Smoke and Carbon Monoxide Detector

The ELRO FF4910 PRO fire prevention set provides comprehensive protection against fire and carbon monoxide hazards with two essential safety devices. This set includes a PS4910 optical smoke detector and a PK4910 electrochemical carbon monoxide detector, both featuring integrated 10-year lithium batteries that eliminate the need for battery replacements during their operational lifespan. Both detectors measure 10.5 cm in diameter and 3.5 cm in height, with each unit weighing 138 grams including the battery. The smoke detector utilizes optical sensor technology that responds quickly to smoke particles while minimizing false alarms, and it automatically dims its LED indicator in dark environments to prevent sleep disturbance. The carbon monoxide detector employs an electrochemical sensor that continuously monitors air quality for the presence of this odorless, invisible gas. Both devices feature automatic monthly self-testing functions that verify operational status without requiring manual intervention, and they produce 85 dB alarm signals when hazards are detected. The smoke detector is suitable for both ceiling and wall mounting, while the carbon monoxide detector is designed for wall installation at approximately 1.5 meters from floor level. Both units comply with European safety standards EN14604 for smoke detectors and EN50291 for carbon monoxide detectors. The set includes all necessary mounting hardware and installation instructions for straightforward setup. For optimal performance, regular maintenance through monthly vacuuming is recommended, avoiding the use of cleaning chemicals. This safety solution is constructed from durable white plastic materials and provides reliable monitoring for residential environments.
