Photoelectric fire alarm

How do you test a fire alarm? Where to buy fire alarms? What is photoelectric device? Download this chart on photoelectric smoke alarms (PDF, 7KB).

For each type of smoke alarm , the advantage it provides may be critical to life safety in some fire situations. The dual smoke detector has both ionization and photoelectric technology inside. While there is some debate regarding the best smoke detector for your home, the general consensus is that ionization smoke alarms are best for detecting rapid flame fires while photoelectric smoke alarms protect against slower, smoldering fires. They’re not as prone to false alarms as ionization smoke detectors, but photoelectric alarms may still be randomly set off if dust builds up inside them.

By Skip Walker, ACI, MCI. Imagine your car air bags deploying randomly when you hit a pothole, but failing over half the time in a collision. Consider placing dual sensor detectors throughout the home to detect both photoelectric and ionization using one alarm.

The photoelectric cell is a highly sensitive instrument and must be carefully installed and calibrated to be effective. The device projects a continuous, focused beam of light onto a mirror. If nothing interferes with the beam en route and back, the sensor perceives no obstruction. With this fire alarm , you no longer need to choose just one technology.

This low-profile smoke alarm uses an ultra-reliable photoelectric sensor to detect smoke from slow-burning, smoldering fires. Experts say photoelectric smoke detectors generally won’t cause as many false alarms , but for the ultimate in safety, they recommend opting for a smoke detector with both types of sensors. The best smoke alarms can detect smoke particles, flames, and carbon monoxide.

A multifunctional alarm can save you battery life or energy from your house for hard-wired smoke detectors. While classic ionization and photoelectric smoke detectors are helpful, smart smoke detectors are the cutting edge in fire safety. Hardwired - connected to the domestic dwelling’s electricity supply.

This will alert the occupants within a house to a fire no matter where the fire starts. Interconnection can be wired or wireless. Photoelectric - the method the device uses to detect smoke.

Vacuum or dust your smoke alarms to help reduce false alarms. Every year Check the expiry date. This is usually located on the bottom or side of the alarm. If your smoke alarm does not have an expiry date on it, it is best to replace it.

Fire Safety Tip: Replace your smoke alarms every years. Although well-maintained alarms typically last about ten years, if you don’t know when your alarms were installe or if they are approaching years, replace them now. Smoke alarms wear out over time. Sources of these fires may include paper burning in a wastebasket, or a grease fire in the kitchen. 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. This hardwired smoke detector uses a photoelectric smoke sensor to reliably detect smoke produced by smoldering fires, helping give you a vital early warning of fire. The smoke sensors are roun ivory in color, and measure four inches in diameter. Once again, smoke alarms are meant to give you extra time to evacuate from a fire , or take action against one if safe to do so.

Therefore, you should get ONLY a photoelectric detector for your kitchen. Or, get a photoelectric combined with CO for your kitchen – and every other room too.
