Photoelectric

The AX-650TF long range photoelectric detectors with selectable beam frequencies. The selectable beam frequencies can be used to avoid unwanted crosstalk that can occur when using multiple photobeams over long distances or beam stacking applications. Also the AX-TF Series employs multiple beam technology and utilizes an AND circuit that requires all beams to be interrupted simultaneously before an alarm is generated. This reduces false alarms due to accidental beam interruption by falling leaves and small animals.

This is a photoelectric single station smoke detector designed to give reliable early warning of the presence of smoke where both audible and visual alarms are required. It has a pulsing LED light source and a photodiode sensor in a fully screened sensing chamber. When smoke enters the chamber, the infrared beam is deflected onto the sensor. The LED rate increases to eight times the normal pulse rate. After the photodiode confirms the presence of smoke for two consecutive pulses, it will produce the signal necessary to trip the audible and strobe light alarms.

THIS AUCTION IS FOR ONE DET TRONICS PYROTECTOR 30-3003 EXPLOSION PROOF SMOKE DETECTOR! NIB! Manufacturer: DET TRONICS / PYROTECTOR Catalog Number: 30-3003 Made by DET TRONICS / PYROTECTOR The photoelectric smoke detector uses a solid state infrared emitting diode (IRED) and a light sensing photovoltaic cell arranged in a labyrinth assembly. The labyrinth permits free access to smoke but restricts external light. Because of its critical function to the operation of the detector, each IRED is selected with extreme care and is subjected to rigorous pre-production testing to ensure long-term reliability and performance
