There are no other flashy design elements, such as a large LED light, so compared with other ‘smarter’ detectors, it may look a bit plain, but it does have everything one would expect from a smoke/CO/gas/fire alarm. If you decide to do it yourself, the installation process is not really that difficult: first, you need to remove the mounting bracket by twisting the main body of the alarm, attach it to the wall and you will now connect the three wires from the wall to the Quick Connector as following: black to the hot side of the AC wire, white to neutral and yellow, if you need to interconnect with other existing alarms the Power has to be turned off prior to this operation. Afterwards, insert the Roost battery, plug the Quick Connector into the Roost RSA 400’s base, reattach the body of the alarm to the bracket and turn on the AC power. The green LED will indicate that the device is powered on and the red LED will blink once every 40 seconds to indicate a proper operation. The USST allows for an early smoke detection during stratification for both fast and smouldering fires using the same sensor for both and, in order to avoid false alarms, the device will operate at a low sensitive level and, in case smoke is detected, it will signal the alarm; it also adjusts and maintains a constant alarm threshold, therefore minimizing the effect of ambient conditions and it features a regulated 5V power supply for the ion chamber. If smoke has been detected, the alarm will beep three times, pause for two seconds and then repeat, the green power LED will turn off and the red smoke LED will start blinking once every second if smoke is detected by another interconnected alarm, the red LED will not turn on.

It seems that Nest Protect actually implemented such a system and, using an omnidirectional microphone, it will speak to you in words besides also using the appropriate colours: there are two types of alerts, the Heads up it’s a calmly spoken warning + yellow LED, when smoke or CO levels are rising but have not yet reached dangerous levels and the Emergency Alerts when smoke or CO are at dangerous levels, the Nest Protect notifies you where is the problem, it turns the LED red and triggers the loud sound alarm – 85dB. Head Up and Emergency alerts can be silenced by pressing the circular button. Note: This device is not intended for people with hearing problems it lacks a flashing strobe of light and the 85db alarm may not be enough in such cases. The Nest Protect runs self tests regularly every 200 seconds to see the status of the batteries and sensors and you can also run a full test to check at any time during this process, you’ll notice a blue light rotating around the button. If you have more than one Nest Protect detectors, you can interconnect them wirelessly the device supports the 802. 11b/g/n standard and Bluetooth Low Energy technology and, in case of an emergency, all the devices will speak at once telling you the location of the triggered alarm the devices shouldn’t be more than 50 feet apart from each other.
