Design Your Security System

The help you need,
the moment you need it.

The smoke/carbon monoxide alarm detects dangerous levels of smoke and colorless, odorless CO — which could go unnoticed by you and your family


Instant Response

First responders are automatically alerted – unlike non-monitored detectors that could let fire or CO spread if you’re in the yard, at work, or just don’t notice early warnings.


Loud Notifications

Loud notifications wake you day or night for
around-the-clock protection.


Pet Protection

Don’t forget about pets. Ensure the safety of your beloved canines and felines with a swift response from the fire department.


10-Year Lifespan

A decade-long lifespan on smoke and CO sensors provides lasting protection. Low battery and end-of-life notifications help ensure detection is always in working order.


Rapid threat detection

The safety and security of the people and assets in your properties are a top priority. Our smoke alarm provides true multi-threat detection and reacts fast to real danger—while helping to reduce false alarms.

A photo-electric chamber senses airborne smoke particulates while an electro-chemical sensor monitors the CO bi-product produced by slow smoldering fires.


Protect against
the unexpected

Infrared (IR) flame sensors that measure ambient light levels and flame signatures, while thermal detection monitors temperature. Sophisticated algorithms interpret and respond to multiple inputs, preventing false alarms.

Automatic drift compensation of smoke and carbon monoxide sensors accommodates for dust build-up over time. Additionally, the reliable electro-chemical sensor has a 10-year lifespan.

Safety you can see
and hear

Audible annunciation is provided by a built-in 85 dB sounder with a one-inch voice speaker. A prominent, 360° viewable LED shows visual alerts.

A smoke alarm condition illuminates red, a CO alarm condition illuminates blue, and a tri-color status LED intuitively indicates the operating mode.
