Potter Electric PE-LFHNW-N Low Frequency Sounder

Product Description

The POTTER ELECTRIC SIGNAL CO. US PE-LFHNW-N is a low frequency sounder designed for wall-mount installation in life safety and fire alarm notification systems. Low frequency sounders emit tones in the 520 Hz range, which research and code bodies recognize as more effective at waking sleeping occupants than traditional high-frequency alarms. This unit is suited for residential and commercial applications where low-frequency audible notification is required to meet current fire alarm and life safety standards. Licensed fire alarm technicians and electricians are the primary installers of this device.

The PE-LFHNW-N is intended for wall-mount deployment in fire alarm notification appliance circuits. It is applicable in residential sleeping areas, hotels, dormitories, assisted living facilities, and other occupancies where low-frequency audible alerting is specified by the authority having jurisdiction. This device fits into notification appliance circuit designs where a dedicated low-frequency sounder is called out on the system drawings.
