For more options, check our smoke and CO detector ratings and our smoke and CO detector buying guide. Here, you’ll find some of the top picks from our tests, listed in alphabetical order. Then it may be time for new smoke alarms. A small connector at the back of each alarm can be unclipped to let you safely remove it from the network. If all of that fails, your ultimate solution may be to disconnect the smoke alarms and remove their backup batteries one by one. If that doesn’t work, flipping the circuit breaker off and back on might stop the noise. First, try the reset button on each smoke alarm. If your smoke alarm has a lithium battery that you can’t take out, muffle it in a blanket, under a sofa cushion, or in your freezer until it stops.Īs for hardwired smoke alarms, “they’re interconnected through the electrical wires, so if one smoke alarm sounds, they’ll all sound, and it can be difficult to figure out what’s going on,” Deitrick says. If that doesn’t work, take the smoke alarm down. Your first step is to find the device that’s going off and reset it by pressing and holding the reset button. Operating Current: 0.Your approach will vary based on the type of power your smoke alarm uses.Operating Voltage: 120V AC 60Hz w/ 9V lithium battery backup.Low Battery Latch: Green LED flashes on for 2 seconds, off for 2 seconds.Latching Alarm: Green LED flashes 2 sec.Up to 18 units of First Alert or BRK Smoke, CO and Heat Alarms.Alarm Reset: Automatic when smoke or CO clears.Electronically simulates smoke or CO condition, causing the unit to alarm.We're still here, still making the most recognized consumer brands of smoke and CO alarms on the market. Over the years, we've seen competitors come and go. This 2-in-1 alarm is also powered by First Alerts trusted technology for smoke and carbon monoxide detection, and warns you to danger in your home and its. We build each smoke alarm, carbon monoxide alarm, heat alarm, and fire extinguisher to the highest standards. It's a responsibility we don't take lightly. products with confidence! Our products are designed to save lives. NOTE: Requires the 120VAC Smart Relay (sold separately) to activate an alert device. The mounting bracket features a large opening for easy access to wiring, and a side load battery drawer provides quick battery replacement without the need to remove the alarm from the ceiling or wall. The alarm is also designed for easy maintenance. This alarm is designed for easy installation with its Perfect Mount System, which includes a gasketless base and a mounting bracket that keeps the alarm secure over a wide rotation range to allow for perfect alignment. However, with the hardwired bridge unit (model SA520B), hardwired and wireless models can be interconnected together on the same mesh network. Ordinarily, wireless and hardwired alarms cannot work together on the same interconnected network. Up to 18 total units can be interconnected, wireless or hardwired: with a maximum of 12 smoke alarms and 6 carbon monoxide alarms. The mesh network of alarms re-routes and resends the signal via other First Alert alarms, providing a greater chance all alarms will receive the signal. First Alert Interconnect Alarms operate on a mesh network that integrates multiple wireless or wired alarms for better safety and response in an emergency. This First Alert Alarm can be integrated into a mesh network with other First Alert Alarms using “Interconnect Technology”. After the alarm condition subsides, the initiating unit will store in memory or "latch" the information and begin to flash the green LED indicator two seconds on, two seconds off, signaling the source of smoke. When interconnected in a series of detectors, the unit that triggered the alarm rapidly flashes its red LED indicator. Additionally, the Latching Alarm Indicator easily identifies the initiating alarm even after the alarm condition has subsided.Īs part of the Smart Technology system, the Latching Alarm feature remembers which detector in your home initiated an alarm. Alarms that do not have the "Smart Interconnect" feature remain silent during a CO alarm. When CO is detected, all alarms sound the CO horn pattern. When smoke is detected, all alarms sound the distinctive smoke horn pattern. The alarm includes "Smart Interconnect" technology, enabling it to interconnect with other BRK Smoke, Heat, and "Smart Interconnect" CO Alarms. Can be interconnected with other BRK Alarms.Dust cover included to keep the alarm clean during construction.Improved UV resistance prevents discoloration over time.Intelligent Sensing Technology that reduces unwanted or nuisance alarms.It connects directly to your home electrical system and comes with a 10 year lithium battery backup. This detector features ionization technology and an electromechanical sensor with Intelligent Sensing Technology that reduces unwanted or nuisance alarms. Keep your family safe from both smoke and carbon monoxide leaks with the First Alert AC Smoke & Carbon Monoxide Alarm with 10 Year Lithium Battery Backup.
