Notification Devices Meet UL Standards

Audible/visible notification devices from System Sensor, St. Charles, Ill., meet the new compliance standards set by Underwriters' Laboratories for current draw and voltage drop that went into effect on May 1, 2004.

Previously, UL measured current draw post-in rush current and did not take into consideration the in-rush or the peak current. The new measurement standard requires all manufacturers to publish one number that considers the in-rush current, peak current and the average current, measures in root mean squared.

All System Sensor products with a date code after May 1, 2004, comply.
