Calectro Optischer Rauchmelder-Einsatz

Calectro Optical smoke switch 16-30 V DC, including short-circuit relay for use in raumen to fruezeitigen detections of Schwellbraenden fire and fire with smoke development .The sensor operates on the principle of scattered light, alarm relay with a potential-free changeover, including mounting base, the light transmitter and receiver are arranged in the Messa chamber so that the Lichtbuendel of the transmitter do not apply directly to the receiver kann.Erst the scattered light on suspended particles (Tyndall effect) reaches the receiver and is in an electrical signal umgesetzt.Eine green LED pollution (service), a red LED indicates the alarm. relay contact loads with 24 V / 1 A. Ambient temperature: minus 20 plus 50 degrees .Leistungsaufnahme: 2.64 watts; VDS test certificate: 205041
