Bellman & Symfon Mobile Phone Sensor The Bellman Symfon Mobile Phone Sensor (BE9250) connects your smartphone or tablet to the Bellman Visit alerting ecosystem so you do not miss important calls or messages. By detecting when the device screen lights up, it activates compatible Bellman alarm clocks, Flash Receivers or the BE1431 Telephone/Multi‑Purpose Transmitter, which then provide loud sound, bright flashes and/or vibration alerts throughout your home. Compact and easy to place directly on a phone or tablet, the sensor is ideal for people with hearing loss, deep sleepers, or anyone who struggles to hear their phone ring, offering reliable multi‑channel notifications day and night. N.B: This product is not stand-alone and requires other Bellman Visit Range solutions in order to work and alert the user. Mobile Phone Sensor Data Sheet Mobile Phone Sensor User Guide
