EQUIVALENT FACILITATION CALCULATOR HELPS ARCHITECTS AND ENGINEERS DESIGN NOTIFICATION CIRCUITS

St. Charles, IL — System Sensor has developed the Equivalent Facilitation web-based calculator in an effort to provide architects and engineers with easy access to a tool that will assist in the design of audible/visible notification device circuits.

By visiting www.systemsensor.com and then selecting the Install/Specify System Sensor Products tab or going directly to systemsensor.com/equivalent_facilitation/index.html, visitors are able to perform notification circuit design calculations by entering ceiling strobe candela values and inputting the longest wall and the ceiling height of the room.

This calculator uses data provided by the user to perform the calculations described in Chapter 7 of the 2002 edition of NFPA 72, which permits the use of a performance-based alternative in lieu of tables for spacing ceiling mounted audible/visible devices. These calculations are described in Section 7.5.4.3 as follows:

To calculate performance-based strobe coverage, the inverse square law is used to calculate the illumination at each of the angles in the horizontal and vertical planes per UL 1971 and the effect of polar distribution is included using the minimum percentages in UL 1971 or actual test results recorded by the Listing organization (per Section 7.5.4.3.2).
The calculated illumination is required to be at least 0.0375 lumens/square foot at any point within the covered area (per Section 7.5.4.3.1).
The calculation points are in the horizontal and vertical planes in 5 degree increments per UL 1971 (to comply with 7.5.4.3.2).
For the effect of polar distribution (rated candela at each angle), the UL 1971 minimum percentages are used for the calculations. UL 1971 does not provide ratings for each angle based on actual test results.

The new calculator can be found on System Sensor's website: www.systemsensor.com.
