Bosch AH-24WP-R Wheelock Weatherproof Electronic Horn, 24 VDC, Red, Requires Backbox

Bosch Wheelock AH-24WP-R Weatherproof Electronic Horn, 24 VDC, Red, Requires Backbox

These Wheelock horns offer tone choices of either continuous horn or temporal pattern (Code 3) tone when constant voltage from the fire alarm control panel (FACP) is applied. Each tone has three field‑selectable volume levels. These horns can be synchronized when used with the SM (single) and DSM (dual) Synchronization Modules or a compatible control panel. If not synchronized, the temporal sound patterns might overlap and not be distinctive.

Key Features:

• Cost‑effective two‑wire design
• Selectable continuous tone or temporal (Code 3) sound pattern synchronization
• Three field‑selectable sound levels
• Weatherproof model available
• Low average current draw
