The Wheelock LFHNKW3-N is a low frequency horn from the Eaton Exceder LED3 sounder line. It produces a 520 Hz low frequency tone. As a result, it helps wake sleeping occupants more effectively than standard high-frequency horns.
This model has a white housing with no lettering and mounts on a wall. It operates on 24 VDC for indoor fire alarm circuits. The audible-only design carries no strobe.
Wheelock LFHNKW3-N features
- 520 Hz low frequency output for sleeping-area notification.
- Four field-selectable modes: Continuous, Temporal 3 (fire), Temporal 4 (CO), and T3/T4 sync.
- 24 VDC operation with a white, no-lettering housing.
- UV-stabilized plastic housing rated for indoor use.
- Low-profile body extending less than 2 inches from the wall.
Codes and applications
The 520 Hz signal meets NFPA 72 and NFPA 720 low frequency requirements for sleeping spaces. Therefore, it suits dormitories, hotels, apartments, and similar occupancies. In addition, the horn carries UL, ULC, CSFM, and FCC listings.
