Nest Protect is a smoke and carbon monoxide alarm designed for residential use. It offers interconnected functionality, allowing multiple units to communicate and alert occupants to the location of a potential hazard. Installation requires a Wi-Fi connection, a compatible mobile device (iOS or Android), and a Phillips screwdriver. The device is available in wired and battery-powered configurations, each with specific installation procedures. Proper installation must adhere to local and national fire safety regulations, such as those outlined by the National Fire Protection Association (NFPA).
Initial Setup and Requirements
Before commencing installation, several prerequisites must be met. A functioning Wi-Fi network and knowledge of the Wi-Fi password are essential. Users will need either an iOS or Android-based phone or tablet to utilize the Nest app for setup and configuration. It is recommended to ensure the Nest app is the latest version. The initial setup, or a factory reset, must be performed through the Nest app.
Local regulations regarding smoke alarm installation vary significantly. Users should consult their local safety agency or Fire Department to ensure compliance with current requirements. Nest Pro installation services, provided by OnTech, are available for those who prefer professional installation and a product demonstration.
Installing a 2nd Generation Wired Nest Protect
The installation process for a wired Nest Protect differs from that of a battery-powered unit. It involves working with electrical wiring and requires caution to avoid electrical shock. Before beginning, power to the installation area must be switched off at the circuit breaker or fuse box.
The process involves the following steps:
- Remove the existing smoke alarm, carefully disconnecting it to avoid damaging the ceiling or wall.
- Unscrew the old backplate from the electrical box, saving the screws for later use.
- Disconnect the wires from the old alarm, using wire nuts to cap the white wires together, then the black wires. Any red, orange, or yellow wire should also be capped with a wire nut.
- Attach the Nest connector, ensuring secure connections.
- Mount the Nest backplate using the previously saved screws.
- Attach the Nest Protect unit to the backplate.
- Restore power to the circuit.
- Complete the setup process using the Nest app, which includes scanning the QR code on the device and connecting it to the Wi-Fi network.
- Test the device by pressing the Nest button. All connected Nest Protects should announce a test message.
Installing a 1st Generation Battery-Powered Nest Protect
Installation of a battery-powered Nest Protect shares some similarities with the wired version but omits the electrical wiring steps. The process includes:
- Downloading and opening the Nest app on a compatible mobile device.
- Adding the Nest Protect to the app, initiating the setup process.
- Mounting the device to the ceiling or wall, ensuring it is at least 10 cm (4 inches) from the wall.
- Completing the setup within the Nest app.
Nest App Integration and Multi-Unit Setup
The Nest app is central to the installation and operation of Nest Protect. It guides users through each step of the setup process, including scanning the device’s QR code, connecting to Wi-Fi, and integrating with other Nest Protect units.
If multiple Nest Protects are present, the app facilitates their simultaneous setup. The app will prompt the user to indicate if additional units are present, streamlining the configuration process. During testing, all connected Nest Protects should communicate, confirming their interconnected functionality. If a unit fails to respond during the test, it may need to be moved closer to other units or reset to factory settings. The maximum range between units is approximately 50 feet, but this can be affected by building construction and wireless interference.
Device Features and Operation
Nest Protect incorporates several features designed to enhance safety and usability. These include:
- Photoelectric Sensor: Detects slow, smoldering fires.
- Carbon Monoxide Detection: Alerts users to the presence of carbon monoxide.
- Interconnected Functionality: Enables communication between multiple Nest Protects.
- Self-Testing: Continuously monitors its own functionality.
- Hush Feature: Allows users to temporarily silence alerts.
- Voice Alerts: Provides audible alerts using a human voice.
- Light Ring: Uses color changes to indicate status and alerts.
- Nest Button: Serves as a test button and a hush button.
The device continuously tests itself, eliminating the need for manual testing. Users can initiate a test by pressing the Nest button twice. During a test, the device will announce, “This is only a test. The alarm will sound.”
Maintenance and Battery Information
Nest Protect requires minimal maintenance. However, the device may accumulate dust over time. Cleaning should be performed without detergents or solvents, and air fresheners or hairspray should not be applied directly to the device.
Battery-powered units utilize three AA Energizer batteries. The device provides advance warning when batteries are running low, allowing users to replace them before they are depleted. Wired units rely on household power but also include a backup battery for use during power outages. However, wired units will not function during prolonged power outages once the backup battery is exhausted.
Safety Precautions and Warnings
Several safety precautions are outlined in the documentation:
- Nest Protect is intended for use in ordinary indoor residential locations.
- It should not be installed in unfinished attics or garages.
- In homes exceeding 93 square meters (1,000 square feet) on one level, additional alarms may be required.
- The device should be installed at least 3 meters (10 feet) away from cooktops or cooking appliances.
- Electrical shock hazard: Power must be turned off at the circuit breaker before installing a wired unit.
- In the event of a carbon monoxide alarm, occupants should immediately operate the reset/silence button, call emergency services, and move to fresh air.
Troubleshooting and Servicing
If a Nest Protect requires servicing, users should first contact the support team to obtain a return number. The device should then be shipped to the designated service location. If a smoke alarm has a yellow or red pulsing light, it indicates that an alert has been hushed. The device will remain quiet unless smoke or carbon monoxide reaches dangerous levels.
Installation Codes and Standards
Installation should adhere to the National Fire Protection Association’s Standard 72 (NFPA 72). Specific requirements for smoke alarm installation vary by country, state, and region, so users should consult local authorities for current regulations.
Conclusion
Nest Protect offers a comprehensive smoke and carbon monoxide detection solution with interconnected functionality and smart features. Successful installation requires careful adherence to the provided instructions, consideration of local regulations, and a functioning Nest account. Regular maintenance and testing are essential to ensure the device operates reliably and provides optimal protection.
