CAUTION:
DO NOT USE THIS PRODUCT IN ANY SAFETY RELATED APPLICATIONS WHERE HUMAN LIFE
MAY BE AFFECTED.
GENERAL INFORMATION
The RM2402D is a wireless receiver that works with any ACI wireless sensor or input concentrator using 900 MHz
spread spectrum technology. The RM2402D has two (2) digital outputs (dry contact) and a low battery/loss of
signal digital output (dry contact) for an alarm. The sensors are programmed to the RM2402D using the
configuration software (included), a laptop, and CK2432D programming cable. The RM2402D can be used to
monitor status or alarms and is compatible with any DDC controller that accepts a dry contact closure.
The maximum radio transmission distance is dependent on the building type. In a typical commercial
building with steel I-Beam construction, concrete floors with reinforcing rod, and metal stud walls, it can be
expected that transmissions will penetrate horizontally approximately 200-300 feet of floor, walls, furniture
and air.
Generally, a wireless system will cover at least three floors–one floor above, and one floor below the receiver
location. In some buildings with favorable transmission characteristics the system may cover more floors -
see
FIGURE 2,
p.2. Wireless sensor transmitters should be installed within 200 to 300 feet of the RM2432D
receiver.
RR2552 signal repeaters can be installed as needed to increase transmission distance between sensors and
receivers - see

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.
MOUNTING INSTRUCTIONS
Mount the RM2402D Receiver using four #8 screws
(mounting dimensions see
Figure 3,
pg3).
WIRING INSTRUCTIONS
WIRING PRECAUTIONS
• Do NOT run Digital Output wires in any
conduit with line voltage (24/120/230 VAC).
• Remove power before wiring. NEVER connect
or disconnect wiring with power applied.
• The RM2402D is full wave rectified.
• It is recommended that you use an isolated
UL-listed Class 2 transformer when powering
the unit with 24 VAC. Failure to wire the
devices with the correct polarity when sharing
transformers may result in damage to any
device powered by the shared transformer.
Observe polarity when connecting analog outputs to the controller inputs.
WIRING
Connect 24VAC 60Hz to the TB1 terminals using 16-26 twisted pair wire. Check all connections before
applying power to the unit.
Using the RM2402D configuration information, connect the digital outputs to the appropriate control
input terminals on the controller or contactor using 20AWG wire.
Connect 24VAC 60Hz to the input terminals using 18-20AWG wire(See
Figure 3,
p. 3). Check all
connections before applying power to the unit.
Configuration
Mount the RM2432D Receiver as close to the controller as possible using four #8 screws (mounting
dimensions see
Figure 3
(p. 3). The maximum wiring distance for the analog outputs is 100 ft.
