Product Features
What this model is for, what it does well, and what to confirm before it goes on a project.
Discreet personal panic alerting in homes, small offices and retail counters where a wall-mounted or portable button is needed.
Two-way RF communication with frequency hopping and AES128 encryption helps keep button events reliably reported to the paired system.
A multi-color LED indicator shows pairing, communication and other statuses so installers can confirm the button is working.
