New Gate Opener, Old Accessories – How do I figure this out?

As the leading gate opener authority we quite often get customers coming to us that have gate openers that have died over the years and they want our advice on putting in a reliable gate opener. However many times the peripheral devices, the gate opener entry / exit/ safety accessories, still work form their prior system and they would like to know how to utilize these to save money. We are always more than happy to oblige with assistance; but in general it will take a little hands on discovering on the home owners part.

First is the accessory you are trying to use wired or wireless? We ask this first because wireless is a rather simple solution that we will knock out right here first. Wireless devices communicate on a radio frequency. Probably it will not match the frequency of the new system as they change by manufacturer and year. However a purchase of a matching receiver to the frequency your wireless accessory (remote or keypad usually) can be wired to any gate opener to receive the signal from the existing device. if you have both a remote and a wireless keypad most likely they transmit on the same frequency so you can use the remote to find the correct receiver. If you visit our website in the transmitter category: http://www.gatecrafters.com/gate-opener-transmitter-accessories; find your existing transmitter. Then look on the left side of the screen where it shows related items. The matching receiver should be there and if you purchase that receiver for your new gate opener then your old wireless devices will be able to work.

For wired devices do not un-wire them from your old system until you have identified and marked the wires as to what they are. Typically there will be 2 or 4 wires being used.

2 wires are typically found on simple devices like push buttons or toggle switches. These do not take any detective work, just identify the two wires and look in the manual for the new gate opener where a push button is wired to and wire them in there.

4 wires typically mean power and a relay. the power is for providing power to the accessory, identify these first as the wires going to a power source on your previous device and mark them. That leaves you with 2 wires left for activating the gate. Many times 2 wires will be in service however 3 are available. This is because most devices have a relay that has a Normally Open and Normally Closed lead that pair with a common. Please watch this video for identifying these wires: https://www.youtube.com/watch?v=xh-lS4tg3MA

Once you learn the NO or the NC and the COM you can wire this device to any gate opener. If it is an entry device you will almost always use the NO and COM. If it is a safety device some gate openers use the NO and other the NC. The manual should specify.

  1. Hello:
    I have a problem with my exit sensor…it will not detect cars and open the gate unless you drive somewhat off the drive and near directly over it. Can you give me suggestions on how I might fix this? The exit wand is only a about 18 months old and had work fine for a year or so then started acting up.

    1. One thing you can try to do is to re-calibrate the wand as it seems to be less sensitive now. To do this you will remove the red wire of the wand from the power source. Then reattach the red wire to the power source and wait 5 minutes before moving metal near the wand. When doing this make sure all metal in the area is clear of the wand area because you do not want the wand to calibrate to that metal being in the area.

      Another reason could be a lower amount of power going to it now then what used to be supplied. If you have a battery operated gate opener the battery could be lower now than it used to be. Check the battery voltage levels, a 12V battery should read around 13.2VDC without the charger attached to it. If it is the battery then either try moving the wand to an independent power supply or replacing the battery. If you do not have a battery operated system try powering it off its own source anyway just to ensure nothing has changed with the power supply you are using.

      Lastly it could be electrical noise. You can try trimming the ends of all the wires to have clean, corrosion free, connections and also grounding the exit wand to a grounding rod.
