The CB 4-s is Code Blue's take on one of the most common style of speakerphone enclosures, commonly referred to as a "call box". It can be deployed on it's own to house a Code Blue faceplate speakerphone or combined with a remote-mount LED beacon/strobe or remote audio paging system, it can extend security efforts to dorm and building entrances, hallways and transit centers.

A version of the CB 4-s speakerphone enclosure, this double opening option can provide additional Help Point® information by using a directory plate in the additional opening. A custom faceplate can also be used to attached various third-party devices such as cameras or access control readers. The increased size also more flexible, providing more room for additional equipment such as a cellular router or more robust power systems.

The CB 4-r is a rugged emergency call box with carbon steel construction and sophisticated hands-free emergency speakerphone, illuminated by an LED faceplate light. It provides direct communication with first responders, and extends security efforts to dorm and building entrances, hallways and transit centers.

The CB 4-u is an all-weather emergency call box highlighted by our advanced NightCharge® power option, which allows you to pull power from a switched light grid and operate 24 hours per day - even when the grid is off. A hands-free emergency speakerphone provides direct communication with first responders and extends security efforts to dorm and building entrances, hallways and transit centers.
