GEV Smoke detector FlammEx FMF 4252

Radio smoke detectors for maximum safety with minimum effort. Simple networking of up to 30 FlammEx radio smoke detectors by radio. The triggering radio smoke detector transmits the signal to all FMF4252 FlammEX radio smoke detectors located within a radius of a maximum of 25 m, which then also trigger. Up to 8 radio groups can be set up to cover different alarm areas. The detector has a test button to check the function of the radio smoke detector and a radio network light emitting diode to indicate functional readiness. It features a 30-day battery replacement indicator, simple and quick installation, a temperature range of 0 °C to +45 °C, and humidity of 0 - 95% (non-condensing). The signal volume is approximately 85 dB at 3 m, with a frequency of 868.082 MHz. It uses a 9 V block alkaline battery (included) with an approximate runtime of 2 years. The range is approximately 25 m (depending on structural conditions), and it is networkable with up to 30 detectors in one group, allowing for up to 8 radio groups. Please note the B.
