FAQ – Miller Edge Transmitter and Receiver
Miller Edge Transmitter-Receiver system eliminates the need to
run hard wire from a 2 conductor Sensing Edge to your
operator’s control panel. Aside, from the ease of installation, it
also makes for a much cleaner appearance.
Sensing Edge activation initiates the transmitter to send a
wireless signal to the receiver to stop/reverse the door or gate
movement.
Q. What batteries should I use in the Miller Edge MWT12 transmitter?
A. To assure battery life use size “AA” lithium batteries.
Q. What batteries should I use in the Miller Edge MWTA12 transmitter?
A. To assure battery life use only size “AA” alkaline batteries.
Q. What frequency does the system operate on?
A. 318MHz
Q. Can MWRT12 be used with a monitored Sensing edge?
A. MWRT12 is designed for use with 2 conductor non-monitored Sensing Edges.
For monitored edges, you’ll want to use the MEL Monitored Edge Link transmitter-receiver
system.
Q. Can MWRT12 be used with pre-2010 door operators?
A. Yes.
Q. Is MWRT12 suitable for outdoor use?
A. Yes, the MWT12 transmitter is in a NEMA4 enclosure. For outdoor installations, the MWR12
receiver should be housed within the operator enclosure for water protection and the antenna
should extend outside of the operator to assure range.
Q. What is the difference between your 2 different models?
A. The MWTA12 has a built in low battery alarm, the MWT12 has no low battery alarm.
Q. My MWTA12 is emitting a loud sound, why is that?
A. This transmitter has a low battery detection circuit with an audible alarm. Simply replace the
“AA” Lithium batteries with new ones.
Q. When I compress my edge the gate does stop and reverse, but I do not hear the warning
sound. What is wrong?
A. Nothing. The alarm is simply a low battery warning. It does not sound on edge compression.
Q. The motor is not reversing. All of my LED’s are coming on as they should and I have
checked my wiring. What else could be wrong?
A. Make certain that the coding DIP switches are set
identically
in the transmitter and receiver.
Take note that each switch has 3 possible settings: + , 0, -.
