All analog sensors are connected to analog ports of remote monitoring units or Power Distribution Units (PDUs), determination of the sensor type and connection will occur automatically.

Conditions monitored include: indoor and outdoor temperature, humidity, AC voltage, door open/closed, vibration, smoke, movement, water leakage and airflow.

All sensors are monitored for: low alarm, low warning, normal, high warning, high alarm. Sensors VT530, VT540, VT560 allows chain connection.

Third party analog sensors can be connected using 4-20mA converter VT420 or 0-10V DC voltage meter VT410-10.
