System Sensor P2WLED-LF – Low Frequency Horn Strobe (White)

The System Sensor P2WLED-LF is a low-frequency horn strobe notification appliance designed for fire alarm systems requiring 520 Hz audible signaling, such as sleeping areas. Part of the L-Series LED platform, it combines a high-output horn and LED strobe in a single wall-mounted unit, delivering both audible and visual alerts.

This device produces a 520 Hz square wave tone, which is specifically required by NFPA 72 for sleeping spaces to improve occupant awakening during emergencies.

Built with modern LED technology, the P2WLED-LF offers lower current draw compared to older xenon strobes, improving system efficiency and allowing for more devices per circuit.
