System Sensor P2RL-LF Low Frequency Sounder Strobe Red

System Sensor P2RL-LF L-Series Indoor Selectable Output Low Frequency Sounder Strobe, 2-Wire, Wall Mount, FIRE Marking, Red

The System Sensor P2RL-LF is an indoor wall-mounted low-frequency sounder strobe designed to provide both audible and visual notification for commercial fire alarm systems. As part of the System Sensor L-Series, it combines a 520 Hz low-frequency sounder with a high-performance strobe to help meet modern occupant notification requirements, particularly in sleeping areas.

Replacing the P2RH-LF, the P2RL-LF features a red housing with FIRE marking and offers field-selectable candela settings, multiple audible tone options, and High/Low output selection. Its advanced plug-in design and universal mounting plate with an onboard shorting spring simplify installation while reducing labor time and minimizing the risk of wiring faults.

Compatible with legacy SpectrAlert, SpectrAlert Advance, and L-Series notification appliances, the P2RL-LF is an ideal solution for both retrofit and new construction applications.
