Hardwired Talking Smoke and Carbon Monoxide Alarm

The First Alert BRK SC7010BV Hardwired Talking Photoelectric Smoke and Carbon Monoxide Alarm detects both carbon monoxide and smoke all in a single device. The combo smoke alarm features a photoelectric smoke sensor and electrochemical carbon monoxide sensor for complete peace of mind. The voice warning alerts you to the type of danger as well as the location. This CO smoke alarm is designed to be hardwired into your home or office. In the event of a power outage, the battery backup allows the unit to continue functioning.

Photoelectric Sensor Warns of Smoldering Fires

This First Alert Combination Alarm comes equipped with a photoelectric sensor to provide the earliest possible warning of fire. The sensor is optimized to detect larger smoke particles produced by smoldering fires, such as those caused by unextinguished cigarettes. It also distinguishes between real threats and smoke/vapor produced during showering, cooking, and other everyday activities, helping minimize the number of false alarms. A patented smoke entry system helps ensures reliable detection by providing a direct air pathway to the sensor.

Electrochemical Sensor Monitors CO Levels

The alarm also features an advanced electrochemical sensor that detects carbon monoxide leaks from a variety of sources, such as faulty fuel-burning appliances, blocked chimneys, and cars left running in the garage. Carbon monoxide can't be seen, smelled, or tasted in the air, and it is the leading cause of accidental poisoning deaths in America. By placing carbon monoxide detectors on every floor of the home and in each sleeping room, you can help protect your family from the danger of carbon monoxide.

Talking Voice Alarm Tells You Where the Danger Is

The First Alert Smoke and Carbon Monoxide Alarm not only alerts you when smoke or carbon monoxide has been detected, but it also tells you where the danger is. Indicator lights on the face of the unit also display the presence of smoke or carbon monoxide. The 85-decibel siren provides a clear, loud warning upon detection.

Interconnectivity for Larger Areas

The hardwired CO smoke alarm can be connected to other compatible BRK and First Alert hardwired alarms for larger buildings such as dormitories, office buildings, and apartments. Connect up to 18 compatible devices: up to 12 smoke alarms and six compatible devices like horns and repeaters. First Alert helps you create a comprehensive warning system for you and your property.

Battery Backup for Continuous Coverage

In the event of a power outage, the CO smoke alarm is still able to function thanks to its two AA backup batteries. An indicator sound is emitted when the batteries need to be replaced, and an optional drawer and mounting bracket lock help prevent tampering.

How to Install First Alert SC7010BV Talking Hardwired Smoke & Carbon Monoxide Alarms:

In this guide, we'll be showing you how to install First Alert Hardwired Smoke and Carbon Monoxide Alarms. Here are a few items you'll need before starting the installation process: Needle-nose pliers or utility knife, screwdriver, wire stripper, wire nuts and a ladder.

Hardwired Smoke or Carbon Monoxide Alarm Requirements:

  • 120V household electrical circuit (unswitched 120VAC)
  • Standard wiring junction box to a 4 in. (10 cm) size, on either the ceiling or wall
  • Selecting an appropriate location to install your smoke and carbon monoxide alarms (see below guidelines for additional information):
    first alert smoke alarm install guide
    • When installing an alarm on the wall, the top edge of an alarm should be placed between 4 in. (100 mm) and 12 in. (300 mm) from the wall/ceiling line.
    • When installing an alarm on the ceiling, place the alarm as close to the center as possible.
    • In either case, install the alarm at least 4 in. (100 mm) from where the wall and ceiling meet.

Connecting First Alert Hardwired Alarms to 120V Wiring

To begin, turn off power at the junction box and connect your alarm to the building's electrical wiring.

  1. Locate the junction box and turn off power
  2. Remove the power connector from the new alarm's packaging
  3. Using wire nuts, attach the hot (black), neutral (white), and interconnect (orange) wires

Black wire
Attach to black wire on power connector
White wire
Attach to white wire on power connector
Orange wire

Standalone (single-station) alarm: This wire is not needed; tuck the orange wire into the junction box.

Interconnected alarms:

  • Strip 1/2 in. from the orange wire on the connector
  • Use a wire nut to attach it to the orange wire in the junction box (see image below).

Mounting First Alert Hardwired Alarms

  1. Secure the mounting bracket to the ceiling or wall using screws (included in the package)
  2. Insert the power connector into the plug on the back of your alarm
  3. Tuck any hanging wires into the junction box
  4. Position the base of the alarm onto the bracket and turn it clockwise until it's secured
  5. Remove the pull-tab to activate the backup battery

Installing Additional and/or Interconnecting First Alert Hardwired Alarms

If you are installing more smoke or carbon monoxide alarms, you'll want to repeat the process throughout the building. Interconnected smoke and co alarms must meet all requirements:

  • The same fuse or circuit breaker must power all interconnected alarms.

  • Up to 18 compatible detectors can interconnect, with a limit of 12 smoke alarms.

  • The total length of wire interconnecting the alarms should be less than 1,000 ft. (300 meters). This type of wire is commonly available at hardware and electrical supply stores.

  • All wiring must conform to all local electrical codes and NFPA 70 (NEC). Refer to NFPA 72, NFPA 101, and your local building code for more information.

  • Interconnect wiring diagram:

If you have any doubts or reservations about these interconnect requirements, please contact an experienced electrician to install your wiring and hardwired alarms.

Restoring Power and Testing Hardwired Alarms

Once you've installed your hardwired alarms, you'll want to restore power to the junction box. Under regular operation, the power indicator light on the alarm will shine/blink to indicate that it is receiving AC power.

Here's how you can test standalone or interconnected alarms:

  • Standalone Alarms: Press and hold the Test/Silence button until the unit triggers an alarm.

  • Interconnected Alarms: Press and hold the Test/Silence button until the first unit triggers an alarm. All interconnected detectors should sound off. Repeat this process to test each alarm in the interconnected series.

Why Is My Smoke Alarm Beeping?

Smoke alarms can beep for to the following reasons:

  • Low Battery: This is the most common cause. Most smoke detectors use a chirping sound (usually a single beep every 30-60 seconds) to warn you that the batteries are running low and need to be replaced. Don't wait until the alarm is silent - replace the batteries right away to ensure your smoke alarm continues to function properly.
  • End of Life: Smoke alarms don't last forever. If your smoke detector is beeping constantly or in a different pattern than the low battery chirp, it may be nearing the end of its intended lifespan and should be replaced altogether.
Product Details
  1. Smoke particles of varying number and size are produced in all fires. For maximum protection, use both ionization and photoelectric sensing technologies. Ionization alarms are generally more sensitive to fast flaming fires and photoelectric alarms are generally more sensitive to smoldering fires.

Very Pleased & Like Voice and Location Feature

I like the voice and location feature of this alarm. You can set one of several locations so when the battery is low or the device needs attention, you know which device needs attention vs. hunting for the beeping device. I will continue to buy these to replace older units in our home.

I prefer to order directly from the product vendor rather than ever using Amazon, and I was impressed with the ease of ordering from your website, and the quick shipment to my house. Plus, the product is so easy to install that I opened the box and within 15 minutes I had replaced the two defective alerts with the new alarms. All of my future orders will be direct with First Alert.
