CHAMBERLAIN LIFTMASTER GARAGE DOOR OPENER KEYPAD UPGRADE

Upgrade to $10/month or $100/year to support multiple devices with a 30-day storage plan. The plan costs $4/month or $40/year for a single device with seven days of history included. People detection and video clip storage, playback, and downloading are all locked to a subscription plan. Not a big deal since the power is seldom out but it could be inconvenient especially if the keypad is a pain to reprogram.Ĥ) Just live with it the way Liftmaster provides.A beefy lithion-ion battery likely accounts for at least some of the myQ Smart Garage Video Keypad’s thick dimensions (the device measures 6.30in x 2.71in x 1.36 inches (HxWxD). This option means each time the power goes out, I lose programming. We can have fairly extreme hot and cold weather so batteries mounted outdoors could see a 100 degree temperature swing from winter to summer and that assumes the device is not mounted where the summer sun can shine directly on it.ġ) Experiment with connecting a wired keypad across the terminals of the Liftmaster wired push button remote.Ģ) Relocate the battery for the wireless keypad into the interior of the workshop where the temperature extremes will be much less and the battery should last much longer.ģ) Wire out a 9 volt power supply and do away with the battery altogether. Batteries would just up and die prematurely and the thing was finicky about being re-programmed. That was one of the problems I had with a previous wireless keypad. Might have to experiment a bit after I get the unit installed.Īnother confirmation I received from Chamberlain is that the wireless keypad loses all memory and programming when the batteries are removed (or die completely). Makes me wonder if I couldn't jumper the wires from a wired keypad across the terminals of this wired remote push button to accomplish having a wired keypad.

Interestingly, they do offer a wired push button remote: That doesn't necessarily help me for entry access but it does give me a convenient push button I can install near the overhead door since the main control panel will be installed at the other end of the building near the walk-in door. And, any wireless unit must support Security+ 2.0 openers. The 8500 cannot work with a wired keypad, only wireless. I contacted Chamberlain and got the definitive word. Maybe the OP should contact an experienced installer who has addressed this or attempted to install a doorbell type switch or wired keypad to an 8500.

CHAMBERLAIN LIFTMASTER GARAGE DOOR OPENER KEYPAD MANUALS

The user manuals for all 3 openers tell you to use wireless wall mounted remotes if you need a button in more than 1 location, so the manual is of no help.Īt this point I can only tell the OP with 100% certainty that the 3900 will operate with the GD-1 keypad. Anyone with an 8500 want to try it? There is nothing in the manual that addresses this. I can neither confirm nor deny whether the 8500 can function by simply shorting the two wires together. Since the 3800 is the same as the 3900, this means that the 3800 can also use the GD-1 or similar wired keypads. This means that the GD-1 is compatible with the LM3900 guaranteed. Another example, the Domino GD-1 that was mentioned, draws it's power from batteries, and has a relay that shorts the two wires together to open the door. For example, I could install 3 doorbell switches (without backlights) and all 3 would function. Thus, this means that ANY device that shorts the two wires together will cause the door to open. However, the 3900 _only_ comes shipped with a dry contact push button as the main control panel. The 38, per the installation manual, indicate that the 377LM keypad entry is listed as an option.
