The Sensor/Transmitters can be used indoors and outside. They are designed to withstand weather including rain and snow but are not designed to be submerged in water. When installed outside the Sensor/Transmitters do best when in a covered area and not in direct sunlight.________________________________________

The Sensor/Transmitter is a passive infrared receiver (PIR). It detects movement by the change it causes in background temperature and then transmits a radio signal to the Receiver/Speaker that movement has been detected. ________________________________________ See similar questions...

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.________________________________________ See similar questions...

Yes, the Sensor/Transmitter will work in the dark or in full light. ________________________________________ See similar questions...

The battery in the Sensor/Transmitter can last up to 1 year depending on if the Sensor/Transmitter is set to battery saver mode. Temperature can also affect the life of any battery. Operating a battery at cold temperature will reduce its life.________________________________________ See similar questions...

The contact block, J1 (item "D" in the diagram), enables the unit to function as a wireless transmitter when triggered by other devices such as magnetic door contacts, smoke alarms, pressure mats, or any other normally-open device. The SW2 switch (item "C" in the diagram) comes set from the factory in the ON position. With the switch in the ON position, the Sensor / Transmitter can be triggered by either the PIR or the contact block J1. See similar questions...

The Sensor/Transmitter can be set to activate an unlimited number of Receiver/Speakers. ________________________________________ See similar questions...

The Sensor/Transmitter is intended to identify children of about 40 Lbs or larger when the Sensor/Transmitter is installed at a height of 7 1/2 feet above the ground. If it is desired to identify smaller children then the Sensor/Transmitter will need to be installed lower to the ground. When animals are present they may create a false trigger. ________________________________________ See similar questions...

The Sensor/Transmitters will transmit a signal in an open area up to 1000 feet to the Receiver/Speaker. Through walls the Sensor/Transmitters will transmit a signal to the Receiver/Speaker up to 300 feet.________________________________________ See similar questions...
