Sentences with phrase «ionization sensor»

They are more resistant to nuisance alarms than all other smoke alarms utilizing an ionization sensor.

The Nest Protect, for example, uses a photoelectric split - spectrum sensor that is considered superior to the ionization sensor used in many older devices and which is more prone to false alarms.

It is nicer looking than the First Alert Z - Wave model, with smooth corners and an elegant rounded shape, but it doesn't come in a wired version, it has only an ionization sensor, and it operates on three standard AA batteries, meaning low - battery chirps are still a possibility.

In its guide to smoke and CO alarms, Consumer Reports issues a challenge to all smoke alarm manufacturers to create «a single device that senses both kinds of fire and CO.» The Nest Protect's Split - Spectrum Sensor purports to cut down nuisance alarms by including a type of ionization sensor, but it isn't a dual detector.

So, on top of retrofitting old alarms, you can buy a Roost Smart Smoke Alarm that can detect CO, all types of smoke (Roost uses a modified ionization sensor, called IoPhic, made by Universal Security Instruments), and natural gas, or you can get a cheaper smoke - only alarm.

However, two smart smoke alarms coming soon promise to offer true dual - sensing smoke detection, with both photoelectric and ionization sensors.

Ionization sensors respond slightly quicker to fast - burning fires, while photoelectric sensors are faster at detecting smoldering fires (the more common type in homes).

That means it uses both photoelectric and ionization sensors to detect smoldering and fast - burning fires.

It's a photoelectric sensor, which is generally better at sensing smouldering fires (ionization sensors are faster at quick - burning fires, but are more prone to nuisance alarms), but Nest's sensor has a second wavelength that's better for picking up flaming fires.

Not exact matches

It is important to make sure that there are both ionization AND photoelectric smoke alarms in the house, or a dual - sensor smoke alarm which contains both.

The spark plugs — each is powered by an individual ignition coil — function as «sensors»; the two auxiliary control units monitor the power signal after every ignition and can immediately identify irregularities in the combustion process through ionization phenomena.

Standard equipment on EX models such as UVO Powered by Microsoft, push button - start ignition with smart key and rear sonar back - up sensors, rear view back - up cameras and air ionization purification technology complete the modern and high - tech driving experience.

Photoelectric sensors are less prone to nuisance alarms and are generally better than ionization at catching smoldering fires that put out bigger particles of smoke.

Consider using dual sensor carbon monoxide alarms which contain both ionization and photoelectric technology in one alarm.

The RSA - 400 uses both ionization and photoelectric sensors to detect fast flaming and slow smoldering fires, carbon monoxide and methane gas.

Ionization - type sensors are best at detecting fast - burning fires, while photoelectric sensors are generally better at alerting you about smouldering, or slow - burning fires.
