Potter CM-4 Electronic Chime with Volume Control

Provide dependable, professional door notification for commercial security and access control with the Potter CM-4 electronic chime. Built by Potter Electric Signal, LLC, this low-profile door chime delivers selectable entry/exit tones and a user-adjustable volume control so installers can tailor alerts to lobbies, reception areas, retail entrances, or monitoring rooms. The CM-4 runs on 12V AC/DC with low power consumption and wired screw-terminal connectivity for reliable low-voltage operation and straightforward wiring.

Designed for system integrators, the CM-4 includes a selectable open-collector trigger output for linking to external circuits and can be combined with Potter people counters (EBP-407C, EWP-202C) to enhance surveillance and traffic monitoring workflows. The CM-4L LED variant offers a bright visual cue for hearing-impaired users or noisy environments where audio alone is insufficient. Ideal for security, access control, and facility monitoring applications, this chime balances performance with simplicity.
