All ACI/34 and ACI/334 semiconductor sensors are polarity sensitive but non-position sensitive. The
ACI/34 Duct sensor is supplied with a 3-Pole terminal block while the ACI/LM334 has a 2-Pole terminal
block for all wiring connections. ACI recommends the use of 18 to 22 AWG twisted pair or shielded
cable for all sensor installations.
