Details:
- IR Wireless Smoke Detector adopts Ion smoke detector element, with siren. It can work individually as well as with other alarm systems.
- Self-alarm when the smoke density exceed the standard density
- A IR Wireless Detector, like this one featuring a Sony CCD color camera, can protect your home in two ways
- The covert camera inside films security footage without being detected, and the working smoke alarm can help alert you in case of a fire
Smoke Detector:
- A smoke detector is a device that detects smoke, typically as an indicator of fire. Commercial, industrial, and mass residential devices issue a signal to a fire alarm system, while household detectors, known as smoke alarms, generally issue a local audible and/or visual alarm from the detector itself
- Smoke detectors are typically housed in a disk-shaped plastic enclosure about 150 millimetres (6 in) in diameter and 25 millimetres (1 in) thick, but the shape can vary by manufacturer or product line. Most smoke detectors work either by optical detection (photoelectric) or by physical process (ionization), while others use both detection methods to increase sensitivity to smoke. Sensitive alarms can be used to detect, and thus deter, smoking in areas where it is banned such as toilets and schools. Smoke detectors in large commercial, industrial, and residential buildings are usually powered by a central fire alarm system, which is powered by the building power with a battery backup. However, in many single family detached and smaller multiple family housings, a smoke alarm is often powered only by a single disposable battery
Optical:
- An optical detector is a light sensor. When used as a smoke detector, it includes a light source (incandescent bulb or infrared LED), a lens to collimate the light into a beam, and a photodiode or other photoelectric sensor at an angle to the beam as a light detector. In the absence of smoke, the light passes in front of the detector in a straight line. When smoke enters the optical chamber across the path of the light beam, some light is scattered by the smoke particles, directing it at the sensor and thus triggering the alarm
- Also seen in large rooms, such as a gymnasium or an auditorium, are devices to detect a projected beam. A unit on the wall sends out a beam, which is either received by a receiver or reflected back via a mirror. When the beam is less visible to the "eye" of the sensor, it sends an alarm signal to the fire alarm control panel
- According to the National Fire Protection Agency "photoelectric smoke detection is generally more responsive to fires that begin with a long period of smoldering (called smoldering fires)" also studies by Texas A&M and the NFPA cited by the City of Palo Alto California state "Photoelectric alarms react slower to rapidly growing fires than ionization alarms, but laboratory and field tests have shown that photoelectric smoke alarms provide adequate warning for all types of fires and have been shown to be far less likely to be deactivated by occupants."
- Although optical alarms are highly effective in detecting smoldering fires and do provide adequate protection from flaming fires, fire safety experts and the National Fire Protection Agency recomend installing what are called combination alarms, which are alarms that either dectect both heat and smoke, or use both the ionization and photoelectric / optical process
- According to a graduate research study done by the University of Cincinnati photoelectric alarms where far less likely to produce nuisance alarms, are superior in detecting smoldering fires, and are almost as effective in detecting flaming fires
- Something to take note of is the fact that not all optical or photoelectric detection methods are the same. The type and sensitivity of the photodiode or optical sensor, and type of smoke chamber differ between manufacturers
Carbon monoxide and carbon dioxide detection:
- Some smoke alarms use a carbon dioxide sensor or carbon monoxide sensor in order to detect extremely dangerous products of combustion. However, not all smoke detectors that are advertised with such gas sensors are actually able to warn of poisonous levels of those gases in the absence of a fire
- Performance differences
- Optical or "toast-proof" smoke detectors are generally quicker in detecting particulate (smoke) generated by smoldering (cool, smokey) fires. Ionization smoke detectors are generally quicker in detecting particulate (smoke) generated by flaming (hot) fires
- According to fire tests conformant to EN 54, normally the CO2 cloud from smoke can be detected before particulate
- Obscuration is a unit of measurement that has become the standard definition of smoke detector sensitivity. Obscuration is the effect that smoke has on reducing visibility. Higher concentrations of smoke result in higher obscuration levels, lowering visibility
Package Included:
- 1 x Smoke Detector

04-06-2011- Other Thoughts: We've always had trouble in our little house with false alarms from cooking and showering. Not so with this unit from First Alert. I tried it out with one unit placed near the kitchen and it worked so well that I ordered another for the bedroom hall.

03-24-2011- Other Thoughts: This has a mounting plate with multiple positions for the holes on each side - it resembles a four-leaf clover where the screw can slip in. I was able to use existing screws in the ceiling from a really old smoke detector. This design provides flexibility in the distance between the screws. That means less chance of having to poke a new hole in the ceiling when replacing an existing unit.

03-17-2011- Other Thoughts: I was happy to find this device to install at my mother's house. She is hard of hearing so it was important to find a smoke alarm that would have a visible component. The fact that it is photoelectric allowed me to install it near the kitchen where forgotten burners under food would cause it to go off, but not so sensitive that it would give a false alarm. Because my mother is short, I mounted them (I bought 2) on the wall just above eye level and within her reach so she could reset the devices if needed. Fairly easy to install although the battery drawer might be difficult to handle when the battery needs to be replaced.

03-09-2011- Other Thoughts: This replaced an old detector that was installed near the kitchen. The old detector went off every time I cooked, which was quite annoying! This new alarm was placed in the same location as the old detector. The steam and smoke emitted by the stove or oven DOES NOT trigger this alarm. Very pleased!

02-24-2011- Other Thoughts: I had an older alarm that was near my Kitchen that would continuously go off when we cooked on the stove. Drove me nuts!. I finally dropped kicked the old unit and replaced it with this one. No more alarms from Cooking. <br/>Good unit.

02-16-2011- Other Thoughts: Great smoke alarm with photoelectric sensor that is more sensitive to smoke than the more typical ionization smoke detectors. It's recommended to have both in your home, but for some reason these photoelectric types are harder to find in stores near us. This once comes with a spot light that will be very hand at the end of our hallway in case of a fire.

02-10-2011- Other Thoughts: I didn't think it'd work, but gave it a try after reading the reviews. <br/>Works *amazingly* well in an area near the kitchen that was really frustrating w/ false alarms. The light is also very useful in that stairwell area.
