Product Description
The BRK First Alert CO5120BN is a hard-wired T4 carbon monoxide alarm with battery backup.
OVERVIEW
The BRK First Alert CO5120BN is a hard-wired carbon monoxide combo alarm with battery backup. It features a CO sensor, Intelligent Sensing Technology™ for fewer unwanted alarms, an 85dB horn, 9V battery backup, side-load battery drawer, two silence features and is interconnectable with up to 18 devices. Applications include residential and institutional applications including hospitals, hotels, motels, dormitories and other multi-family dwellings.
The Intelligent Sensing Technology" system is designed to reduce nuisance alarms. The "Latching Alarm Indication" remembers which unit initiated an alarm. When interconnected, the unit that triggered the alarm rapidly flashes its red LED indicator. After the alarm condition subsides, the initiating unit will store in memory or "latch" the information and begin to flash the red LED indicator once every 5 seconds.
The "Smart Interconnect" feature allows the unit to be interconnected to other BRK CO and smoke alarms. If there is a smoke event, the interconnected CO5120BN horn pattern will emit the T4 alarm sound, the same sound as a smoke alarm (4 beeps, pause, 4 beeps). If there is a CO event, the interconnected CO alarms will sound with their normal horn pattern. Battery installation and removal can occur while the unit is mounted via the side load battery compartment.

I purchased a townhouse, and the one the builders put into my home didn't work. Once again, I was shocked to find this item on-line, when I could not find it anywhere else. It was the exact model that I needed! Works great, very quick delivery.

It's to sensitive, if the oven is on it sets it off. We have a gas and CO meter witch shows it being at a safe reading. We do not use it on the first floor, we use it only in the basement. We are trying to find one we can use on the first floor.

Got this as a replacement when our old one started beeping. It was super simple to replace, I just pulled out the battery tab, popped off the old one and put this one in. I didn't use the bracket since it fit in the old one without any problems.
