It is best to place the sensors as close to the design indicated location as possible. Amatis has two types of sensors; and the most commonly used sensor type is Sensor 2. Sensor 2 is powered by an RJ12 cable connected to a Smart Driver or an Advanced Load Controller. Sensor 2 comes in two varieties - horizontal RJ12 connection and vertical RJ12 connection.
The vertical RJ12 connection is ideal for applications where the sensor is mounted in a ceiling tile, drywall, or any instance where it would be easiest to plug in an RJ12 cable from the topside.
The horizontal application is best used when the sensor is positioned against a hard ceiling like a cement surface and the RJ12 should be plugged in from the side.
The other type of sensor, Sensor 1, doesn’t have an RJ12 connection because it is capable of communicating wirelessly across the mesh network. This device has two wires for low voltage, 24V DC power.
