H-240 24VDC Mini Buzzer/Horn

The Alpha Communications® H-240 24VDC Mini Buzzer/Horns are typically used with the LI118B Corridor Dome Lights and the AlphaEcall™ (AEC100), CM800, NC110A, NC110N, NC150N, NC200N and DS100 systems.

Because of their incredible flexibility and compact size, these buzzer/horns can be used for hundreds of stand-alone applications where a 24VDC mini buzzer/horn is required.
