How Do I Wire and Use a COSMO-2W Combination Smoke/CO Detector?
Wiring a COSMO-2W is very similar to using a 4-wire smoke. The COSMO-2W connects to a COSMOD-2W. The COSMOD-2W then connects to the panel. Learn to use the COSMO-2W.

What Gauge Wire Should I Use for a CO Detector?
Alarm Grid recommends using 18-gauge wire when installing hardwired carbon monoxide sensors. Some building codes may require this. Learn why 18-gauge wire is great for CO sensors.

How Does a Fire Detector Work?
There are two primary methods for detecting a fire. These are through either smoke detection and heat detection. For that reason, a "fire detector" is more commonly referred to as a "smoke detector" or a "heat detector". There are also combo smoke and heat sensors. Learn more about these devices.

What's the Best Place to Install a Smoke Detector?
When choosing a location for a smoke detector, there are some things to remember. For example, it should be placed away from any vents or ducts that might affect its performance. It should also be at least 10 feet away from any kitchen appliances. Learn more about where to place a smoke detector.

How Do I Add a 2-Wire Smoke Detector to My Wireless Alarm System?
Adding a 2-wire smoke detector to a wireless alarm system is not possible. A 2-wire smoke detector can only be added to Zone 1 of a wired alarm system. This is because that particular zone contains specific logic needed for a 2-wire smoke to function properly. Learn more about 2-wire smokes.
Added:

Will a Smoke Detector Detect Heat?
Not all smoke detectors are designed to detect the presence of high heat. These sensors will only detect high heat if that is a specific function of the device. Otherwise, a smoke detector will only detect smoke, and nothing more. Learn more about smoke detectors and their functionality.

Where Do I Place a Carbon Monoxide Detector?
You should have at least one CO detector on each floor of your home. Some common locations for CO detectors include near bedrooms and near attached garages. The devices should be placed 5 feet off the ground and away from direct sunlight or moisture. Learn more about where to place CO detectors.

Where Should I Install a Carbon Monoxide Detector?
There are some simple guidelines to follow when deciding where to install a CO detector. Depending on the size of the building, you may need to install more than one. Typically, there should be at least one CO detector on each floor of the building. Learn more about where to install a CO detector.
