What is an external bellbox?

An external bellbox is a security device commonly used in alarm systems, designed to alert individuals to a triggered alarm. Typically mounted on the exterior of a building, it features a loud siren and often includes flashing lights to deter intruders and notify nearby residents. The visible presence of a bellbox can act as a deterrent to potential burglars, signaling that a property is protected by an alarm system. Some models may also incorporate features like remote monitoring or connectivity to a central alarm system.
