The Wheelock NH-12/24-R is a wall-mounted audible alarm horn from Wheelock designed for indoor fire alarm systems, with dual-voltage operation at 12 VDC or 24 VDC. It is part of the NH Series Horns that offer selectable tone and output levels for flexible installation in life-safety applications.

Selectable Tone Pattern: Offers a continuous tone or a temporal (Code 3) pattern to meet different signalling requirements.
Selectable Output Volume: Two audible output settings (90 dB and 95 dB at 10 ft) allow adaptation to ambient noise conditions.
Universal Mounting Plate: Designed for mounting to single gang, double gang, 4-inch square, or European 100 mm back-boxes, enabling flexible wiring and retrofit.
Indoor Listing: Listed under UL Standard 464 for audible signal appliances (indoor use).
Red Housing: Standard red “FIRE” housing (-R suffix) for fire-alarm visual identification and code compliance.
