MOUNTING
It is critical to the performance of this device that the antenna be
oriented vertically. It must point straight up or down for proper
operation. When installing the DIM10-281-21 in an enclosure, antenna
position must be considered in order to provide optimum wireless
signal strength. For best transmission, all antenna should be oriented
vertically.
For a standard installation, place the light controller in the desired
location inside the fixture and secure it using (4) #4 machine screws.
Make sure the head of the screw does not extend outside the silk-
screened circular pattern on the printed circuit board at each hole
location. Use a nylon stando at least 1/4” in length between the
board and the mounting surface to prevent shorts.
Before permanently installing it, verify the antenna can be mounted
external to the fixture and allows adequate room for connecting the
coax cable from the DIM10-281-21 to the antenna. Also, make sure the
antenna can be oriented vertically and is free from blockage by any
surrounding metal. (see Figure 1)
INSTALLATION INSTRUCTIONS
WARNING: TO AVOID FIRE, SHOCK, OR DEATH: TURN OFF
POWER AT CIRCUIT BREAKER OR FUSE AND VERIFY
THAT POWER IS OFF BEFORE WIRING!
MOUNTING (CONT.)
1. Connect the electrical service black wire (hot) to the
LINE input on the DIM10-281-21.
2. Connect the black wire of the LED fixture to the
LOAD output on the DIM10-281-21.
3. Connect the electrical service white wire (neutral)
to the NEUTRAL input on the DIM10-281-21 and the
NEUTRAL input on the fixture..
Note: Steps 4-6 are for Class 1/2 Dimming Control
4. Connect the DIM- wire from the fixture LED driver to
the DIM- input on the DIM10-281-21.
5. Connect the DIM+ wire from the fixture LED driver to
the DIM+ input on the DIM10-281-21.
6. Switch power on to the fixture. The light should turn
on.
Note: When switched on, lamps should turn on to full
brightness. Approximately 10 VDC signal should
be present on the DIM+ wire using the DIM- wire
as reference.

Declaration of Conformity (FCC 96-208 & 95-19): Synapse Wireless,
Inc. declares that the product name “DIM10-281-21” to which
this declaration relates, meet the requirements specified by the
Federal Communications Commission as detailed in the following
specifications:
• Part 15, Subpart B, for Class B equipment
• FCC 96-208 as it applies to Class B personal computers and
peripherals
• This product has been tested at an External Test Laboratory
certified per FCC rules and has been found to meet the FCC,
Part 15, Emission Limits. Documentation is on file and available
from Synapse Wireless, Inc.
If the FCC ID for the module inside this product enclosure is not
visible when installed inside another device, then the outside of the
device into which this product is installed must also display a label
referring to the enclosed module FCC ID. Modifications (FCC 15.21):
Changes or modifications to this equipment not expressly approved

REGULATORY INFORMATION
RF Exposure Statement: This equipment complies with FCC radiation
exposure limits set forth for an uncontrolled environment. This
equipment should be installed and operated with minimum distance
of 20cm between the radiator and your body. This transmitter must
not be co-located or operating in conjunction with any other antenna
or transmitter.
Industry Canada (IC) certifications: This digital apparatus does
not exceed the Class B limits for radio noise emissions from digital
apparatus set out in the Radio Interference Regulations of the
Canadian Department of Communications.
Le present appareil numerique n’emet pas de bruits radioelectriques
depassant les limites applicable aux appareils numeriques de la
class B prescrites dans le Reglement sur le brouillage radioelectrique
edicte par le ministere des Communications du Canada.
FCC certifications and regulatory information (USA only)
FCC Part 15 Class B: This device complies with part 15 of the FCC
rules. Operation is subject to the following two conditions: (1) These
devices may not cause harmful interference, and (2) These devices
must accept any interference received, including interference that
may cause harmful operation.
RADIO FREQUENCY INTERFERENCE (RFI) (FCC 15.105): This
equipment has been tested and found to comply with the limits
for a Class B digital device, pursuant to Part 15 of the FCC rules.
These limits are designed to provide reasonable protection against
harmful interference in a residential installation. This equipment
generates, uses, and can radiate radio frequency energy and, if not
installed and used in accordance with the instructions, may cause
harmful interference to radio communications. However, there is no
guarantee that interference will not occur in a particular installation. If
this equipment does cause harmful interference to radio or television
reception, which can be determined by turning the equipment o and
on, the user is encouraged to try to correct the interference by one or
more of the following measures: (1) Re-orient or relocate the receiving
antenna; (2) Increase the separation between the equipment and
the receiver; (3) Connect the equipment into an outlet on a circuit
dierent from that to which the receiver is connected; (4) Consult the
dealer or an experienced radio/TV technician for help.
INSTALLATION INSTRUCTIONS (CONTINUED)
Note: Steps 7 - 10 are for attaching sensors. The label for the
terminal blocks are oset on the board. Refer to figure 3
to see how the labels correlate with the terminal block.
7. Connect the DIM10-281-21 SNSA input to the first
sensor output and SNSB to the second sensor output (if
applicable).
8. Connect the DIM10-281-21 SNSR signal to the Common
(ground) connection on the sensor(s).
9. Connect the DIM10-281-21 PWR output to the power input
on the sensor(s).
10. Connect the DIM10-281-21 RTN input to the Common
(ground) signal on the sensor(s).
Note: Steps 11 - 12 are for using the auxiliary output. The
auxiliary output is a “sink-only” output that can be used
to activate an external switch or relay. It can sink up to
40mA at 24V* max. It tracks the state of the internal
relay.
11. Connect the auxiliary output to one side of the low-voltage
coil (relay example).
12. Connect the other side of the low-voltage coil to the PWR
output on the DIM10-281-21.
DIMMING
Below are some recommendations for successful dimming using
the DIM10-281-21. The dimming control wires are referenced as
Dim+ and Dim- . The dimming signals have a Maximum voltage
of 10V DC.
• Use multi-strand 18 Gauge Wire for noise immunity and
current capability
• Do not ground the dimming wire. This is a return signal and
is critical for dimming.
• When possible, route dimming wires away from AC lines
• Use connections with properly sized connectors.
• Eliminate excess wire between fixtures. Line length will
cause voltage drop.
• Number of fixtures that can be daisy-chained depends
on the following factors: dimming current, current
requirements for driver, length of wire, quality of
connection, and gauge of wire
• Verify dimming capability via a “test bed” with the number
of actual fixtures, wire length, connectors, and wire gauge
