Low Frequency Application Guide Now Available from System Sensor
System Sensor’s low frequency notification application guide is now available. It covers waking effectiveness, low frequency requirements, occupancy and building code impact, system applications, and more.
The Low Frequency Notification Appliances Guide is intended to provide information about low frequency (520 Hz) notification appliance requirements used in fire alarm and carbon monoxide systems. It not only outlines the development of the NFPA 72, NFPA 720, and UL standard requirements, but it also provides guidance for placement and usage of low frequency notification appliances within fire alarm and carbon monoxide systems.
