How often will the Sensor/Transmitter send a signal?
The Sensor/Transmitter has two modes for sensing movement and sending a signal. The (setup) mode that is set at the factory identifies all movement and transmits each detected movement to the Receiver/Speaker. The battery saver mode will detect movement every 3 minutes and then transmit to the Receiver/Speaker. Removing the jumper in the Sensor/Transmitter will setup this mode.
