Optical smoke detector

An optical beam smoke detector is a device that uses a projected beam of light to detect smoke across large areas, typically as an indicator of fire. They are used to detect fires in buildings where standard point smoke detectors would either be uneconomical or restricted for use by the height of the building. Benefits of optical smoke detectors. The advantage of optical smoke detectors is they are good at detecting smoke from carbon-based heavy material like coal, fabric, and wood.


These slow-burn fires typically produce a lot of soot laden smoke with large particles. How Optical Smoke Alarms Work. An optical smoke alarm (also called photo-electric smoke alarm ) works using the light scatter principle.


The alarm contains a pulsed Infra red LED which pulses a beam of light into the sensor chamber every seconds to check for smoke particles. Ionization detectors are more sensitive to the flaming stage of fires than optical detectors , while optical detectors are more sensitive to fires in the early smouldering stage. This monkey shaped smoke detector not only looks great in the childrens bedroom, but it also provides safety.


This smoke detector is approved for wall and ceiling mount. The flow smoke detector is an optical smoke detector for domestic households (living room, hallway and bedroom). A loud alarm signal sounds when smoke is detected. As you can see, both detectors use a source and a sensor an when the smoke prevents the sensor from being able to detect the radiation or light, the alarm is triggered. This Kidde 10-Year smoke detector is easy to This Kidde 10-Year smoke detector is easy to install and alerts your family when fire or smoke is detected in your home.


Smoke alarms should be placed outside each sleeping area and on every level of the home. Smoke enters through the slits around the side, triggering an electronic horn, which sounds through the large circular opening on the right. The dark circle in the middle is a test button with a built-in LED that flashes to show the detector is working okay.

The Optical Smoke Detector uses a state of the art optical chamber combined with an application specific integrated circuit (ASIC) to provide quick and accurate detection of fires. A combination of the unique chamber design and other technically advanced features will significantly extend the service intervals before cleaning of the detector. How does optical smoke detectors work?


What is the best home smoke detector? Do You need a smoke or CO detector? What are the two types of smoke detectors? Fast and Free Shipping On Many Items You Love On eBay. This hardwired ionization smoke alarm has all of the standard features: a silence button, a low battery alert light, and an easy-to-access backup battery.

As FDRdoes not react to temperature changes, it is suitable for installation in data centers and telco rooms. The second type of smoke detector is photoelectric, which uses a light beam to help detect the presence of smoke. According to NFPA, these alarm types are more effective at sounding when a fire originates from a smoldering source, like a lit cigarette that falls into a couch cushion. The detector is particularly suitable for detecting optically dense smoke , involving materials such as soft furnishings, PVC, plastic, foam and all similar materials which produce small visible particles ( to 10μm). This hardwired alarm includes a 9V battery backup in case of a power outage, and it can be used as a standalone unit or part of an interconnected system.


The XPOptical Smoke detector uses an internal pulsing infrared LED and a photo-diode at an obtuse angle. In clear air conditions the photo-diode in the XPdetector receives no light from the LED and produces a corresponding analogue signal. Ionization smoke alarms are the most common type of smoke alarm and are quicker at sensing flaming, fast moving fires. This type of alarm uses a small amount of radioactive material to ionize air in an internal sensing chamber.


The OmniShield state-of-the-art smoke sensor is the most reliable smoke detection unit in the industry due to both the quality of its components and the precision manufacturing methods.
