WiBell Dry Contact Bell Controller
The WiBell Dry Contact Bell Controller is a programmable relay controller designed for facilities that already have bells installed. It replaces your old timer or controller — you keep your existing bells, wiring, and power source.
The controller does not supply power to the bell. It works by closing the bell circuit through a dry contact relay. When a scheduled event triggers, the relay closes and your existing bell rings using its own power source.
Setup and control are handled locally from a phone or computer using the built-in WiFi hotspot and web interface. No internet, no cloud, no subscription.
