Smoke Alarms

Smoke alarms are devices that detect smoke and sound a loud alarm to alert the user of the possibility of fire.

Smoke alarms that are ionized have a higher sensitivity to flaming fires, while photoelectric alarms are better at detect smoldering fires. It’s recommended that homes have both types of smoke alarms in order for maximum protection.

There are two kinds of smoke alarms that are available that are battery-operated and hardwired.

Carbon monoxide (CO) is an inert gas with no color and smell that is produced by the incomplete combustion of various fuels, like natural gas, propane, and wood. CO can be deadly in high concentrations, making it vital to install a carbon monoxide detector in your home.

Carbon monoxide detectors function by sensing the level of CO in the air, and then emitting an alarm when levels become unsafe. There are two types of CO detectors available including battery-operated and plug-in. For plug-in detectors, professional assistance is required for installation while battery-operated detectors are easy to set up and maintain.
