USI electric smoke and carbon monoxide detector review
Design
These are the most solid wel-built goof proof alarms I have installed. They come vacuum packed, battery installed, and with dust covers for those still within the remodeling process. They are wired and battery backed up.
Sensor
Advanced smoke recognition gives the MICN109 a faster response to smoldering fires than conventional smoke alarms. Auto sensitivity calibration provides superior nuisance alarm protection and creates consistency in alarm sensitivity. This alarm has additional automatic features including a self-diagnostics check and a sensitivity adjustment for changes in temperature or humidity. The 9-volt alkaline battery (included) continues protection in the event of a power outage.
Loud alarm
When one alarm activates, interconnected alarms sound throughout the home, providing additional time to escape safely. It produces 85dB sounds which is loud enough to warn about the incident.
Installation
They are easy to install. They matched up perfectly with the outlets. These detectors are designed to be linked to each other so in the event that one detector goes off, they all go off. Detectors have a limited life (seven years is typical), so please ensure yours are still good. The expiration date is stamped on inside the housing. I placed a label on the outside cover so no one will be tricked in the future.

First Alert SA511CN2-3ST alarm
The UL-certified First Alert SA511CN2-3ST alarm comes in a two-pack, and the units (and any additional ones) can interconnect so that if one sounds, they all sound, which can give you additional time to identify the problem and evacuate. This wireless-connection setup is internal to the alarms and does not require a phone app. You can also designate each unit by location so that if an alarm is tripped, all of them indicate which room the hazard is originating from. The First Alert SA511CN2-3ST is the only model that combines all of those features in one bundle—and at a price that’s just slightly above average for the category, it’s a good value. Also, because it has a voice alert rather than a beep or a tone, our interviewed experts told us, it’s more apt to wake a sleeping child.
