Kidde Hardwire Smoke and Carbon Monoxide Combination Detector with AA Battery Backup, Voice Alarm, and Ionization Sensor - KN-COSM-IBA

The Kidde KN-COSM-IBA is a hardwired device that combines the functions of both smoke and carbon monoxide alarms. So anyone could say you’re getting two devices for the price of one.

With this unit (and multiple others), you can create a security network of alarms for your home for maximum protection against fires and carbon monoxide poisoning.

The price tag is very modest, but the device sure packs a lot of features. You’ll definitely get more for what you’ve paid for it.

Here are the unit’s specs and features you can rely on once the Kidde KN-COSM-IBA is installed in your home:

• The unit is hardwired

You’ll have to hire someone to install this to your home, especially if you plan to install a network of alarms (which is advisable).

Most homeowners don’t know that smoke alarms should be installed in every room of the house, not just the more obvious places like in the kitchen or by the fireplace.

• Able to connect with 24 other devices (with 18 initializing alarms)

Build a secure network of alarms in your home to ensure that every space is covered if any hazards occur.

• Electrochemical sensor

This sensor is responsible for keeping track of the CO levels in your home. CO cannot be detected with our senses. That’s why it’s important to have a device like this to make sure that your family is protected against CO poisoning.

An electrochemical sensor is basically working electrode.

CO would disturb the zone around the working electrode and would therefore trigger the alarm.

CO poisoning itself does not have any special symptoms. It would just seem like you have the flu. You’ll never know if someone has actually been poisoned unless you consult with your doctor.

• Ionization sensor

This sensor is responsible for detecting flaming fires. This type of fire burns quickly.

An ionization sensor would easily detect this because it is designed to monitor smoke within its surrounding area.

How does it do this? An ionization sensor is basically a very tiny amount of radioactive material wedged between two electrically charged metal plates. This creates an ionized zone around the unit.

When smoke comes in contact with this zone, the alarm will start to sound off. This also doubles as a CO detection sensor too.

• It talks!

Comes with a voice warning that goes, “Warning, carbon monoxide” or “Fire, fire, fire…”

• Front load battery compartment for easy access (batteries are included in the unit)
• Backup power provided by AA battery to keep you protected in the event of a power outage
• 85 decibel alarm - guaranteed to be heard anywhere in the house
