Area

Area is determined by multiplying length and width (in feet). If the area is already known, it may be directly entered. If not, enter the length and width to have the calculator determine the area.

Due to current limitations, this calculator is only able to make determinations based on a rectangular room where sensors can be spaced evenly throughout. As such, only the length and width (or rectangular area) is needed to establish a floor plan. If your project is more complex, you can always break your area down into smaller rectangles that can be entered individually into the calculator. If perimeter mounting is the only viable option, double the area.

Ceiling Height

Ceiling height should be measured in feet from above the finished floor to below the finished ceiling. If the ceiling height is not known, the default used is 13 feet.

Air Change Rate

Air change rate, measured in air changes per hour (ACPH or ACH), is calculated by dividing the hourly volumetric flow rate by the volume of the area to be covered. Usually, flow rate is measured in cubic feet per minute (CFM), so this value would need to be multiplied by 60 (minutes per hour) before dividing by the volume (length x width x height). If this value is not known or cannot be computed, the default used is 6 ACPH.

Gas Type

Select your target gas(es) to be measured. At least one gas must be selected.

Input Voltage

Select the voltage that you will be supplying the gas detector. Note that some accessories may be required to obtain the desired input voltage.

System Type

If the desired type of system is known, make the appropriate selection. This will force the calculator to determine the components list accordingly. If not known, selecting “Any” will let the calculator determine the most cost effective system type based on the input criteria.

Results

The quantities of controllers, remote transmitters, and accessories as determined by the calculator will populate here. Your recommended detector will be the simplest option based on the number of sensors required for the area to be covered. This is only a recommendation and not the only option that will work. For more advanced areas or specific use cases, other detector models are available in a variety of configurations. Click on each recommended product to learn more.
