Model 1051
SAFETY EDGE TRANSMITTER
Important! Read
Before Installation
The MULTI-CODE 1051 transmitter has been designed to
provide great reliability and safety, but it must be installed
correctly. Read the enclosed instructions carefully.
The Model 1051 may be used for a variety of purposes,
and wherever remote signaling is desirable, as specied
by FCC & IC regulations. If this transmitter is to be used in
an application which may be safety related be sure to take
special precautions. Nortek Security & Control LLC has
taken every step to insure the best possible product, but
you must be certain to install the 1051 transmitter correctly.
Before installing the 1051 transmitter, open it up by
removing the four screws which secure the top of the
case. You will note that there is a terminal block (see gure
1), to which you will secure the wires coming from your
device. Run your wire through the strain relief tting, leaving
enough wire to provide adequate length for stripping.
YOUR WIRE SHOULD BE 18 TO 24 GAUGE, although any
wire that ts snugly in the strain relief tting may be used.
Be sure to check the water-tightness of the tting if you
use anything other than 18-24 gauge wire, as this may
compromise the integrity of the case. Put your two wires
under the terminal blocks, and fasten by screwing down.
Next, code your transmitter and, if necessary, your receiver.
The code switch (see gure 1) allows for 1024 possible
combinations. If you have an existing receiver, you may
code the 1051 to the same code, or you may choose to
wire a separate receiver. If you wire a second receiver, be
sure to separate the two receivers as much as possible, to
avoid any possibility of interference.
3. You should test your entire system occasionally in
order to be sure that all components are working in
good order.
4. Nortek Security & Control LLC’s dealers can provide
you with information regarding the use of our radio
controls, and can provide valuable installation and
operation information, when requested.

PRINT INSTRUCTIONS:
INSTR,INSTL,MC1051,GATE XMTR, PN: 216977 Rev-B, INK: Black, MATERIAL: 20 LB, MEAD BOND, SIZE: 7.500” X 7.500”, SCALE: 1-1

If you are going to use the 1051 transmitter in a safety
related device, be sure to read the manufacturer’s
instructions with regard to wiring and limitations of the
safety circuit.
After you have wired and coded the 1051, you are now
ready for mounting. You will note that there are four holes
in the case, through which you can mount your screws,
rivets, or other mounting devices. If the transmitter is to be
used in the proximity of metal, be sure to test the location
at the greatest distance the device will be from its receiver,
in order to be sure that adequate performance is achieved.
ANY METAL, INCLUDING MOUNTING PLATES, ETC., MAY
AFFECT THE PERFORMANCE OF YOUR TRANSMITTER.
Once you are satised with the performance of the radio,
you can permanently mount it.
Nortek Security & Control LLC has taken every precaution
to assure that the 1051 will perform reliably. In order to
provide the greatest reliability, we have fastened the printed
circuit board to the case with a special fastening agent,
such as Loctite™. We suggest that you use a similar
material to your fastening screws if vibration is likely to be
encountered.
IMPORTANT SAFETY TEST
Before releasing the radio transmitter for use, test the
system for proper operation after installing the radio
transmitter and associated hardware. The system
should be tested at various positions of travel of the
gate member to be certain that the gate edge, radio
transmitter, receiver and gate operator are functioning to
detect an obstruction and reverse or stop the gate.
MAINTENANCE
The 1051 Transmitter needs a minimum of care, however,
certain precautions must be taken:
1. Be sure to check the 1051 Transmitter as a system. Be
sure that the device that is connected to the 1051 is
functioning with the transmitter, and with the receiver.
2. Check the system to which the 1051 is attached
frequently.
3. The 1051 employs long life Alkaline-Manganese
Dioxide Batteries (Eveready Energizer 522 or
equivalent). Nominal life for these batteries is three
years, but we suggest you test the unit more often
than this. Test the transmitter any time you perform
maintenance on the rest of the system.
