Serene Innovations CA‑DX Door Knocker Sensor‑Transmitter – CentralAlert

The CentralAlert CA-SOS Emergency Help Button is a wireless personal pager designed as an optional accessory for the CentralAlert Visual Alert System. This water-resistant device is specifically designed for paging HELP in emergency situations. When activated, it sends a wireless signal to the CentralAlert Master-Unit, triggering all alerting outputs while displaying "SOS" on its screen. To ensure proper functionality, install the batteries and verify that the transmit indicator blinks when the SOS button is pressed. This indicates that the unit is working normally. Registration of the CA-SOS with the Master-Unit is necessary for it to operate within the system. Simply press and hold the SOS/Test button on the Master-Unit to set it to Learn mode, then do the same with the CA-SOS button until the Master-Unit responds. Registration is complete, and the Learn mode can be ended by pressing the Snooze/Reset button.
