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


Analog sensorsDaisy 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:
