GENERAL INFORMATION
The ACI Hazardous Room Sensor is a single point
wall mounted temperature sensor that is designed
for use with electronic controllers in commercial and
industrial heating and cooling building manage-
ment systems. It is available with multiple thermistor
or RTD options. Hazardous Room sensors come
standard with a heavy-duty Copper-Free Aluminum
Connection Head that meets Class I, Division 1 & 2,
Group A, B, C, D; Class II, Division 1, Groups E, F, G;
Class II, Division 2, Group F & G; class III standards.
For optimal temperature measurement, follow
these tips:
•
Do not install on external walls.
•
Do not install near heat sources. eg: lamps, radiators,
direct sunlight, copiers, chimney walls, walls concealing
hot-water pipes.
•
Avoid air registers, diffusers, vents, and windows
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 certification 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) off the ground and at least 1.5’ (0.5
m) from the adjacent wall. Remove the cover from the housing by twisting off the cover. Attach the base
directly to the wall. Mounting holes are located at the corners of the housing – see
FIGURE 1
(above). Seal
fittings, intrinsically safe barriers, and explosion proof flex fittings
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.
