This procedure applies to the following sensors, which are supported by the appliance and are connected to the analog ports:

Analog sensors

Daisy chain

VT500 / Temperature sensor

VT501 / Outdoor temperature sensor 

VT510 / Humidity sensor

VT520 / AC Voltage detector

VT520DIN / AC Voltmeter

VT530 / Access sensor

VT540 / Vibration sensor

VT550/ Wind speed meter

VT560 / Smoke sensor

VT570 / PIR sensor

VT572 / Radar motion sensor

VT591 / Cable leak sensor

VT593 / Spot leak sensor

VT530 and VT560 are the only analog sensors that allow non-addressable chain connection.  All the sensors in one chain are seen by the system as one sensor.  One chain can have up to 10 sensors. Example of such connection:
