Apollo Series 65 55000-317APO Smoke Detector

The Apollo Series 65 55000-317APO Optical Smoke Detector with Flashing LED is engineered to maintain safety integrity and provide reliable early warning detection across commercial offices, retail outlets, educational institutions, healthcare facilities, and residential properties. Utilizing an internal pulsing infrared LED and photo-diode assembly, this conventional detector measures light scattered by smoke particles entering its optical chamber, making it highly responsive to slow-burning or smoldering fires involving furniture, textiles, and paper. Constructed with a white polycarbonate housing, wide 9V to 33V DC operating voltage range, integrated anti-tamper head lock, and a red indicator LED that flashes periodically during normal quiescent operation and latching bright red during an alarm, it ensures clear visual operational confirmation and seamless integration with conventional fire alarm control panels.
