Underwriters Laboratories (UL) 2572 : Mass Notification Systems


UL 2572 is similar to UL 864, the standard to test fire alarm control units. UL 2572 is an equipment standard that sets the standards and criteria for how the control units for mass notification systems will be designed and tested. UL has designed a battery of tests to meet standards to ensure a product achieves a minimum level of performance, and is capable of performing while under duress. These tests ensures that a system will function properly in the event of an emergency.


Reliability Tests Include:


  • Construction / Mechanical


    Environment - Exposure to Freezing and High Heat Temperatures as well as High Humidity Conditions


    Electrical - 20,000 volts into every input and output connector
