Photoelectric smoke detector for the PowerMaster system. PowerG bidirectional radio technology. Higher level of smoke detection sensitivity, provides early warning of fires at startup. Provides audio and broadcast alerts (for smoke, tamper, low battery). Built-in piezo 85 dB audible alarm at 3 m. Sensitivity and degradation indicators, indicating when the sensor must be cleaned. Visible indication of signal quality on the device. It employs advanced AES-128 encryption algorithm for message identification. Frequency Hopping- Spread Spectrum and TDMA technology provide robustness and reliability similar to wired systems. Visible low battery indication. Configuration from the panel, there are no switches and no need to reopen the detector once closed. Simple installation to wall or ceiling, with bracket (included). It works with a 3 V lithium battery type CR123A. Battery life, 5-8 years with normal use. Operating temperature: -10 to +50 ºC. Dimensions: Ø 120 x 58 mm. EN50131 certificate. Grade 2.
