Combination Smoke And Carbon Monoxide Detectors
Combination Smoke And Carbon Monoxide Detectors – The first Alert BRK SC9120B hardwired smoke and carbon monoxide alarm uses electrochemical CO sensor technology and an ionization sensor to detect smoke. It includes a 9-volt battery for continuous operation in the event of a power outage and includes a test/mute button, tamper-proof locks, and a universal mounting bracket. This CO smoke detector can be connected to other compatible BRK and First Alert smoke and carbon monoxide detectors. The latching alarm indicator automatically determines which device triggered the alarm even after the alarm conditions have disappeared.
Designed to meet the latest engineering requirements, the smoke and carbon monoxide first alert combination detects two hazards: smoke and carbon monoxide. The light on the front of the alarm tells you what the threat is, and false alarms can be silenced with the press of a button.
Combination Smoke And Carbon Monoxide Detectors
This hardwired combination smoke and carbon monoxide detector can be connected to other compatible BRK or First Alert CO smoke detectors in a single family home. All connected CO smoke detectors sound when an alarm is triggered. The latching alarm indicator on the CO smoke detector automatically identifies which device triggered the alarm, even after the alarm conditions have disappeared.

The First Alert Combination Smoke and Carbon Monoxide Alarm integrates with existing wiring and features a universal mounting bracket that makes installation quick and easy. Side-loading battery compartment makes changing the 9-volt battery easy. Anti-tamper locking pins prevent unauthorized disabling of the CO smoke detector.
In this guide we will show you how to install a First Alert Hardwired Smoke and Carbon Monoxide Alarm. A few things you’ll need before you begin the installation process: needle-nose pliers or utility knife, screwdriver, wire stripper, wire nut, and stepladder.
To begin, turn off the power at the junction box and connect the alarm to the building’s electrical wiring.
If you set off a smoke or carbon monoxide alarm, you will repeat the process throughout the building. The relevant smoke and auxiliary detectors must meet all requirements:

If you have any doubts or reservations about these wiring requirements, please contact an experienced electrician to install the wiring and connect the alarm.
After setting the alarm, you will want to re-power the junction box. During normal operation, the alarm power indicator will light/blink to indicate that it is receiving AC power.
It is important that you have the correct location of smoke detectors. Install your alarm at least 20 feet away from appliances such as stoves and ovens that produce flammable particles. Alarms should be at least 10 feet away from high humidity areas like showers and laundry rooms and at least 10 feet away from heat/AC fans. Be sure to install smoke alarms, one in each bedroom, one at the top of the stairs, and one on each level.
Chances are your smoke alarm continues to beep and the alarm indicates the battery is low. If the smoke alarm continues to sound, replace the battery immediately.

Other causes include: It could be another device or device such as a security system, monitor, carbon monoxide alarm, or other device with a low battery level or warning signal. Some of the factors that cause unwanted alarms can also cause intermittent alarms: dust and insects in the alarm or electrical wiring in the alarm. Improper wiring of AC or AC/DC smoke detectors. If the interconnect cable is grounded, the AC alarm sounds every 5 seconds. The orange connection cable should never be grounded; It should only be used to connect other smoke detectors or compatible devices.
It is important to check your smoke detectors frequently. When testing a smoke alarm, there may be several reasons why the alarm may not sound:
Why does my smoke alarm go off when I insert the battery or turn on the power?
It is normal for smoke detectors to turn off and emit a short beep (up to 5-10 seconds) when a new battery is installed or turned on. If the alarm persists and there is no smoke, the cause may be one of the following:

User manuals for First Alert smoke detectors are available for free download online. You can find your alarm in our smoke detectors section.
Why does the National Fire Protection Association (NFPA) recommend replacing home smoke detectors after 10 years?
Smoke detectors have a limited lifespan. Although every smoke alarm and its parts have gone through many rigorous tests and are designed to be as reliable as possible, some parts can fail over time. Therefore, you should check the devices weekly. If the device is not working properly it must be replaced immediately. Smoke detectors older than 10 years are simply unreliable. To ensure your family’s safety, combined carbon monoxide and smoke/carbon dioxide alarms should be replaced every 5-7 days. year. All smoke detectors should be replaced every 10 years.

If it’s time to replace your alarm, consider the new 10-Year Life Series and you’ll never have to worry about replacing the battery for the life of your alarm. 10-year alarms are available as smoke, carbon monoxide and combination alarms.
If the carbon monoxide alarm continues to sound, the battery may be low or weak. First alert: Check if the battery light is yellow or green on carbon monoxide detectors. If the alarm goes off and the light is yellow, it means the battery is low. The way to get a carbon monoxide alarm to stop chirping is to replace the battery.
It is very important to install a carbon monoxide alarm near the sleeping area or in each area. Many states now require carbon monoxide alarms to be installed in all bedrooms. For added protection, it is recommended that additional carbon monoxide alarms be placed at least 15-20 feet away from furnaces or fuel-burning heat sources. Also install carbon monoxide alarms at least 10 feet away from sources of moisture, such as bathrooms and showers. In two-story homes, install carbon monoxide alarms on each floor of the house. If you have a basement, it is recommended to place a lead alarm at the top of the basement stairs.
Do not install carbon monoxide alarms in garages, kitchens, furnaces, or areas that are excessively dusty, dirty, damp, or oily. Do not install the alarm in areas exposed to direct sunlight or extreme temperatures. These include unconditioned crawl spaces, unfinished attics, uninsulated or poorly insulated roofs and sheds. Carbon monoxide alarms should not be installed in compartments that are closed off by curtains or other obstacles. Do not install near ceiling fans, heat vents, air conditioners, fresh air return, or open windows in turbulent air. The blown air prevents carbon monoxide from reaching the CO sensors.

So how many carbon monoxide alarms should you have in your home? The National Fire Protection Association (NFPA) recommends having a carbon monoxide alarm outside each separate sleeping area, near the bedroom. For added protection, you should have additional carbon monoxide alarms in every bedroom and on every level of your home, including the basement. Some states now require carbon monoxide alarms in every bedroom in your home. If your home only has one carbon monoxide alarm installed, place it in or near your bedroom.
The following procedure is the correct way to test a carbon monoxide alarm – press and hold the test button on the front of the alarm until the alarm sounds. Make sure you press the button long enough; It may take up to 20 seconds to respond to the alarm test.
If my carbon monoxide alarm goes off and nothing seems to be wrong, is it a false alarm?
Carbon monoxide alarms should not cause false alarms if your alarm is working. Remember that carbon monoxide is an odorless, colorless gas. If your carbon monoxide alarm goes off, it has detected a potentially harmful amount of carbon monoxide. Once experts assess the situation, make sure no one is showing symptoms of carbon monoxide poisoning.

No, the single function carbon monoxide alarm only responds to carbon monoxide. Explosive gas detector is required to detect explosive gas. Different types of explosive gases can be detected, and it is recommended that every home using natural or propane gas has at least one explosive gas leak detector.
