Keep every level of your home protected with the Brennenstuhl RM L 3101 Wireless Smoke Detector. Designed for enhanced home safety, this advanced smoke alarm can be wirelessly interconnected with up to 40 compatible smoke detectors, ensuring that when one alarm detects smoke, every connected unit sounds simultaneously. This makes it an ideal solution for multi-storey homes, apartments, care facilities, and larger buildings where early warning is essential.
The RM L 3101 is powered by a permanently integrated 10-year lithium battery, providing long-lasting reliability without the need for battery replacements. It features a powerful 85 dB alarm, visual status indicator, and a test button for quick functionality checks. In the event of a false alarm, the convenient mute function temporarily silences the detector, while the "Do Not Disturb" feature suppresses low-battery warning sounds when needed.
Unlike smart smoke detectors, the RM L 3101 requires no Wi-Fi, internet connection, or mobile app, making installation and operation simple for any household. When an alarm is triggered, the initiating detector flashes its LED, allowing you to quickly identify the source of the smoke while all connected detectors sound the alarm. Built to meet DIN EN 14604 standards and carrying the Q quality seal, it delivers dependable fire protection you can trust.
