MOUNTING INSTRUCTIONS
This product must be installed by a trained profession-
al with knowledge of local codes and regulations. Before carrying out any work, ensure local regulations and
site procedures are followed to maintain the overall certi cation of the sensor. The sensor should be mounted
in an area where air circulation is well mixed and not blocked by obstructions.
For mounting on a wall, ACI recommends a height of 48-60" (1.2-1.5 m) o the ground and at least 1.5' (0.5
m) from the adjacent wall. Remove the cover from the housing by twisting o the cover. Attach the base
directly to the wall. Mounting holes are located at the corners of the housing – see FIGURE 1 (above). Seal
ttings, intrinsically safe barriers, and explosion proof ex ttings not provided by ACI.
Drill pilot holes for the mounting screws. Use the enclosure mounting holes as a guide, or use the
dimensions listed in FIGURE 1(p. 1). A 1/2" NPT tapping is located at the top of the enclosure.
Refer to the wiring instructions (p 2) to make necessary connections. The housing is provided with Green ground
screw if the housing requires an earth ground. After wiring, attach the cover to the base.
