System Sensor HCRL2-LF is an L-Series 2nd generation low frequency sounder for ceiling mounting, in red with plain (unmarked) housing.
It produces a 520 Hz square wave tone, the type of signal the product data ties to NFPA 72 requirements for sleeping spaces. The sounder-only version has no strobe, so the tone and volume are the settings an installer works with.

- Rotary switch for tone and volume selection
- Coded setting available on sounder-only models
