The System Sensor P2WLED-LF is a white, wall-mounted, two-wire low-frequency sounder strobe for fire alarm and life-safety notification systems. It combines an audible alarm with an LED visual strobe and produces a 520 Hz square-wave tone designed for applications requiring low-frequency notification, including sleeping areas.

The unit operates across a 16–33 V range and provides selectable strobe candela and tone/volume settings. It is designed for compatibility with supported fire alarm systems and should be installed according to the manufacturer's instructions and applicable codes.
