If two or more fans are installed in the same compartment and operated in parallel, the fans must start and stop at the same time.

An auto-restarting alarm occurs when a fan is forced to run forward (or backward) rotation with a speed higher than 

150 rpm.

If an ext. 4-20mA device is used, it is necessary to add 0.1% precision resistances between the ANALOG 

INPUT and GND.

The value of the resistance can range from:

125 Ω -> V

signal

 ranges from 0.5V to 2.5V

to 500 Ω -> V

signal

 ranges from 2V to 10V
