Wheelock AH-24WP-R 24 VDC Weatherproof Electronic Horn (Red)
Usually leaves our warehouse the same business day.
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.
