MEET YOUR NEST PROTECT Inside the box you’ll find: Terminal blocks Nest Protect Backplate Four mounting screws 230V AC cable connector Nest Protect is designed to detect smoke and carbon monoxide in a residential environment. Its eight sensors work together to understand what’s happening in your home and its photoelectric sensor detects smoke. Nest Protect can be used as a single station or multiple station alarm. The installation of this apparatus should be carried out by a competent person.
Horn enables Nest Protect to alert you with a loud emergency sound. 13.4 cm (5.28") Speaker allows Nest Protect to speak with a human voice. Light ring changes colour to alert you. Push the Nest button to silence alarms and run a test. 4.1 cm (1.63") Micro-USB connector (not for normal use). AC connector pins for the 230V cable connector. Backup battery compartment: 3 AA Energizer® Ultimate Lithium batteries (L91).
LOCATION IN YOUR HOME The law requires a smoke alarm on every floor and a carbon monoxide alarm in every room containing a fuel burning appliance. The Nest Protect smoke and carbon monoxide alarm should be installed: • On every floor (required by law for smoke alarms). • In every room containing a fuel burning appliance (recommended for CO alarms). • In every sleeping room. • In remote rooms that are used often but which may be too far away to hear an alarm. • Outside of unused rooms, like the boiler room.
PLACEMENT ON THE CEILING OR WALL Installing on the ceiling is recommended. Mark where the screws will go using the backplate as a guide. Make sure it’s at least 30 cm (12 in) away from the wall.
PLACEMENT ON A SLOPED CEILING If you have a sloped, pitched or cathedral ceiling, Nest Protect should be 90 cm (35 in) from the highest peak.
SETUP AND INSTALLATION (Professional installation recommended) 1. Wake it up Remove the dust cover and pull out the battery tab to wake up Nest Protect. The installation of a smoke/CO alarm should be made by a qualified technician, and all wiring used to install this alarm should be made in accordance with the British National Electrical Code, the British Standard BS 7671, with appropriate national electrical installation regulations and/or applicable codes in your local jurisdiction.
4. Set up Nest Protect 5. Turn off power The video at nest.com/uk/protect/installation shows how. Protect yourself and avoid blowing a fuse. Switch off the correct circuit breaker or remove the fuse from the fuse box. The app will guide you through creating a free Nest account, pairing Nest Protect securely, and telling Nest Protect which room it’s in.
8. Remove the old backplate 9. Connect the cables Unscrew the backplate from the ceiling or dry lining box. You’ll see one or two cables coming from your ceiling. Each cable from the ceiling or wall contains three or four differently coloured conductors. Wiring colours may vary based on the age of the wirings.
Match the live conductors coming from your ceiling to the live conductors in Nest’s 230V AC cable connector and put them into a terminal block. All the neutral conductors go into another terminal block, and the earth conductors into a third terminal block. There is no need for the interconnect cable as all Nest Protect are wirelessly interconnected. If there’s an interconnect conductor, insulate it.
10. Install Nest Protect backplate 11. Connect power Screw the backplate to the ceiling/wall or dry lining box if present using the Nest screws. You can use two or four screws in any open slot on the backplate (Use fittings suitable to the material from wall/ceiling). Plug the 230V cable connector in the back of Nest Protect. Refer to the diagrams on page 6 and 7 for proper placement of Nest Protect. 12.
14. Press to test 15. Have more smoke alarms? Press the Nest button and follow the spoken instructions to test. Nest Protect will run a test and tell you when it’s done. Repeat steps 1-14 to install more Nest Protects. The Nest app will help you connect them to Wi‑Fi and add them to your Nest Account. Test that all the Nest Protects are wirelessly connected by pushing the Nest button twice on one Nest Protect. If they’re connected, every Nest Protect in the house will speak up.
OPERATING INSTRUCTIONS When the Nest Protect smoke and carbon monoxide (CO) alarm has something to say, it will speak to you in words and colours instead of just beeping. It has two kinds of alerts: Heads-Up and Emergency Alarms. • Nest Protect can see smoke or carbon monoxide levels rising. So before it turns on an Emergency Alarm, Nest Protect gives you a friendly spoken Heads-Up to warn you in advance. It pulses yellow and speaks to you, telling you what and where the danger is.
EVERY DAY SILENCING TROUBLE SIGNALS You turn off the room lights for the night, and the GREEN light pulses once. Nest Protect has tested its sensors and batteries to confirm they are working correctly. This is Nightly Promise. WHITE light. Pathlight lights your way at night as you pass under it. YELLOW or RED pulses. You’ve silenced an alert. Nest Protect will now keep quiet, unless smoke or carbon monoxide reach dangerous levels.
HEADS-UP AND EMERGENCY ALARMS ALERTS Nest Protect has two kinds of voice alerts: Heads-Up and Emergency Alarms. Both tell you what and where the danger is, but the spoken Heads-Up is designed to give you a friendly warning before conditions get dangerous. A Heads-Up can be silenced by pushing the Nest button. When smoke or carbon monoxide reach dangerous levels, Nest Protect tells you where the emergency is and pulses red, in addition to making a loud alarm sound. This is an Emergency Alarm.
WIRELESS INTERCONNECT Once your Nest Protects have been wirelessly connected, they’ll all speak up at once in an emergency. That means when one Nest Protect raises any kind of alert, every Nest Protect in the house will tell you which room the smoke or CO is in. For example, if you’re in the bedroom and the alarm goes off in the cellar, the Nest Protect in the bedroom will tell you there’s smoke in the cellar. To silence the alert, go to that room and press the button on the Nest Protect there.
TESTING NEST PROTECT SELF-MONITORING Nest Protect continuously tests itself, so you don’t have to wonder if it’s working. When you turn out the lights for the night, Nest Protect will glow green for a moment that means everything is working. If it glows yellow, this means Nest Protect has detected something wrong that needs your attention. Just push the Nest button to hear its warning: either the batteries are low, Wi-Fi has been down or there is an issue with its sensors.
GENERAL MAINTENANCE CLEANING YOUR NEST PROTECT Use a damp cloth to clean your Nest Protect. Don’t clean it with detergents or solvents and do not spray air fresheners, hair spray or other aerosols near it. These chemicals will damage your smoke alarm and make it non-operational. Cleaning fluids, polishes, paints, cooking operations may affect the reliability of the smoke alarm. Do not disassemble your Nest Protect or clean inside it. If a continuous alarm occurs, return for servicing.
WARNING Never remove the batteries from a battery-operated alarm to stop an unwanted alarm (caused by cooking smoke, etc.). Removing batteries disables the alarm so it cannot sense smoke, leaving you at risk. The alarm will not operate without battery power. The alarm cannot work until you install the batteries in the correct position (Match “+” to “+” and “-” to “-”). This device contains lithium batteries. If tampered with, the battery may be short circuited and create a risk of fire.

SAFETY ALARM LIMITATIONS LIMITATIONS OF SMOKE ALARMS Alarms reduce deaths resulting from home fires worldwide. However smoke alarms can only work if they are properly located, installed and maintained, and if smoke reaches the alarms. • Smoke alarms may not waken all individuals. Make sure you create an escape plan and you practice fire drills with all members of the family. • Smoke alarms cannot work without power.
ageing. Special smoke alarms should be installed for those who are hearing-impaired. • This smoke alarm is not intended to alert hearing impaired residents. Alarms specifically designed for the hearing impaired, which feature devices like flashing strobe lights or low frequency devices are available to alert the hearing impaired in case of fire.
INSTALLATION CODE Specific requirements for Smoke Alarm installation vary from state to state and from region to region. Check with your local Fire Brigade for current requirements in your area. WARNING Smoke alarms are designed to alert you with an audible alarm at a level specified by the British Standard BS EN 14604: 2005. WARNING The smoke alarm accompanying this user’s guide employs the latest technology and is independently tested as being compliant with all the relevant British Standards Institution.
AC INSTALLATION WARNINGS SMOKE DETECTION Are more smoke alarms desirable? The required number of smoke alarms might not provide reliable early warning protection for those areas separated by a door from the areas protected by the required smoke alarms. For this reason, the use of additional smoke alarms for those areas is recommended for increased protection. The additional areas include the dining room and hallways not protected by the required smoke alarms.
• The alarm cannot be operated from power derived from a square wave, modified square wave or modified sine wave, inverter. These types of inverters are sometimes used to supply power to the structure in off grid installations, such as solar or wind derived power sources. These power sources produce high peak voltages that will damage the alarm • Never disconnect the power from an AC powered unit to stop an unwanted alarm. Doing so will disable the unit and remove your protection.
CARBON MONOXIDE (CO) PRECAUTIONS WHERE NOT TO INSTALL YOUR CARBON MONOXIDE ALARMS • Keep carbon monoxide alarm at least 1.5 m (5 ft) away from any cooking appliance including stovetop, oven, microwave, etc.
WHAT TO DO IN CASE OF A CARBON MONOXIDE ALARM • Many cases of reported CARBON MONOXIDE POISONING indicate that while victims are aware they are not well, they become so disoriented they are unable to save themselves by either exiting the building or calling for assistance. Young children and household pets are typically the first affected. WARNING This carbon monoxide alarm is designed to detect carbon monoxide from any source of combustion. It is NOT designed to detect any other gas.
FIRE SAFETY PRECAUTIONS III) Simultaneous operation of several fuel burning appliances competing for limited internal air. IV) Vent pipe connection vibrating loose from clothes dryers, boilers, or water heaters. V) Obstructions in or unconventional vent pipe designs which amplify the above situations. 2. Extended operation of unvented fuel burning devices (range, oven, fireplace, etc.). 3. Temperature inversions which can trap exhaust gases near the ground. 4.
EU DECLARATION OF CONFORMITY WHAT TO DO IN CASE OF FIRE • Get out now. • Don’t panic; stay calm. • Operate your safety plan as previously planned. • Alert small children in the home and those who may need extra assistance. • Leave the building as quickly as possible. Touch doors with the back of your hand and make sure they are not hot before opening them. Use an alternate exit, if necessary. In case of smoke, crawl along the floor, and DO NOT stop to collect anything. Close the doors behind you.
