21 to Nov. 28, you can save $20 on the Nest Protect and other Nest products through the Google Store. It's important to have at least one, if not more, working smoke and carbon monoxide detectors in your home or apartment. However, if they go off while you're not there, how will you know if something's amiss?Smart smoke detectors, such as the Nest Protect, will send you an alert to your smartphone in the event of an emergency. But there are other reasons why this $100 device is our top pick. DesignNest's smoke detector is a bit larger than your standard model, measuring 5. 3 x 5. 3 x 1. 5 inches. It's square, with rounded corners. The center of the device has a circular LED that changes color depending on what's happening; yellow means there's smoke or carbon monoxide, but it hasn't yet reached critical levels; red means you need to get the heck out of there.

Furthermore, besides the transparent Silence / Test button positioned ion the side, there aren’t any other elements to break the minimalist design continuity. At first glance, you’d be tempted to simply position the smoke detector on a shelf and not bothering installing it on the wall or ceiling, but since you want it to detect the smoke as fast as possible, you should mount it on the ceiling and a bit further from the corners of the room it’s also ideal to keep it at least 15 feet away from a fuel burning heat source, so it won’t trigger those annoying false alarms. That being said, the installation process is simple and intuitive: all you have to do is remove the card from the bottom of the mounting bracket, attach the ring to the ceiling or wall using the fixing anchors they’re provided inside the package, fortunately and afterwards, simply rotate the alarm into place. The most popular types of sensors that are used to detect the smoke particles are the ionization sensors and the photoelectric sensors some manufacturers have developed their own proprietary sensors to detect more than one type of fires, such as the case of the Nest Protect with its Split Spectrum sensor. The ionization sensors are used to detect the small particles from fast burning fires, but because of their nature, they’re more prone to false alarms these type of sensors are usually found built into older smoke detectors. The photoelectric sensors can detect larger particles, so it is a lot more useful for smouldering fires those which have not yet erupted into flames, so they’re better for an early detection and are less likely to trigger false alarms. The First Alert P1010 uses the aforementioned technology, so it has a beam of light inside a small chamber which does not directly hit the photoelectric sensor, but, the moment smoke particles enter the device through the holes in the metallic section, the light gets diverted and it will immediately hit the sensor, thus sounding the alarm. In case a fire is detected, you will be able to hear three beeps, pause, three beeps, pause and repeat, while the LED light will flash rapidly – the LED is located inside the Silence / Test button the horn is loud, reaching up to 85 db, 10 feet away from the device – if you have a hearing impairment, it is advisable to have a look at smoke alarms with built in strobes. 1. Which type of sensors are equipped on the smoke detectors?Smoke detectors can have two types of sensors: ionization sensors, photoelectric sensors or both usually called dual sensors. The ionization sensor is used to sense flashing fires by detecting the small particles generated by these fast burning fires and triggering the alarm.
