every data transmission. The data transmission
rate is programmed into the sensor (normally 75
second intervals).
Once the sensor location has been determined
mount the sub-base on an inside wall
approximately 4.5 feet from the floor (or in the
specified location) to allow exposure to the
average zone temperature using two #8 screws,
Velcro™ or double sided tape.
Take care when mounting. Check local code for
mounting height requirements. Typical mounting
heights are 48-60” (1.2-1.5 m) off the ground and at
least 1.5’ (0.5 m) from the adjacent wall. The sensor
should be mounted in an area where air circulation
is well mixed and not blocked by obstructions.
*Reference FIGURE 2
For optimal temperature measurement:
•
Do not install on external walls.
•
Avoid air registers, diffusers, vents, and windows.
•
Avoid confined areas such as shelves, closed cabinets, closets, and behind curtains.
•
Eliminate and seal all wall and conduit penetrations. Air migration from wall cavities may alter temperature
readings.
•
A thermally-insulated backing should be used when fitting to solid walls (concrete, steel, etc.). ACI part:
A/ROOM-FOAM-PAD
•
Do not install near heat sources, eg: lamps, radiators, direct sunlight, copiers, chimney walls, walls
concealing hot-water pipes.
Attach the cover to the base by snapping the top of the cover on first and then the bottom. Tighten the
cover down, using the (2) 1/16” Allen screws located in the bottom of the housing. A 1/16” Hex driver is
needed to secure the cover to the base.
Locate and record the sensor ID numbers located on a label inside the unit prior to mounting.
Ruggedized Enclosure: Attach the cover of the sensor by installing the four screws.
The sensor has a Low Battery LED that will start to blink continuously when the battery voltage is low. A
low battery signal is also sent to the receiver for remote indication that the battery should be replaced. If
the battery is not replaced in approximately 2 months, the battery voltage will become so low that the Low
Battery and Data-Link LEDs will not blink. Replace the battery and the Data-Link LED will start blinking
while the sensor is re-establishing communications with the receiver.
GENERAL INFORMATION
The WH2630 is a battery operated spread
spectrum wireless wall humidity temperature
sensor.
ACI’s mesh network wireless sensors utilize
reliable Spread Spectrum Radio technology.
They can be installed easily in minutes
eliminating hundreds of feet of wire and saving
installation cost while reducing installation labor
risks.
The sensor Data-Link LED confirms the data
transmission was received by the receiver for fast
and reliable positioning of the sensor during
installation. There is no need for special wireless
installation equipment or tool.
The ACI wireless sensors can be used with any
LON works, BACnet, Modbus, or DDC control
system or panel.
Transmission distance in a typical building is
200-300 feet horizontal depending on the layout
and construction of the building, and one floor
above and one floor below the transceiver.
Sensor distance and reliability can be increased
with the addition of a RR2552B(s) repeater.
MOUNTING INSTRUCTIONS
Wireless sensors should be installed within 200 to 300 feet of the receiver. RR2552 signal repeaters can be
installed as to increase transmission distance between sensors and receivers.
CAUTION:
Observe battery polarity when installing battery.
To select the proper sensor location, first install and power the receiver. To activate the sensor insert the
battery observing the polarity.
While the sensor is attempting to connect to the receiver the Data-Link LED will blink rapidly 8–10 times
every 10 seconds. Once a connection has been established the Data-Link LED will blink once to indicate
the data transmission has been received successfully. The Data-Link LED will continue to blink once for

PRECAUTIONS
SENSORS, REPEATERS AND RECEIVERS SHOULD NOT BE INSTALLED IN THE FOLLOWING AREAS:
• INSIDE METAL ENCLOSURE / PANEL
• INSIDE OR IMMEDIATELY NEXT TO ELEVATOR SHAFT / ELEVATOR BANKS
• IN FRONT OF OR IMMEDIATELY NEXT TO LARGE TREES OR LARGE BODY OF WATER
TRANSMISSION DISTANCE AND PERFORMANCE WILL BE DRASTICALLY REDUCED.
CAUTION:
DO NOT USE THIS PRODUCT IN ANY SAFETY RELATED APPLICATIONS WHERE HUMAN LIFE
MAY BE AFFECTED.
