Question

Garage door safety sensor wire requirement


My garage door opener installation manual (139.53413) stated that garage door safety sensors were optional at the time I installed my garage door opener (about 20 years ago). I now want to install safety sensors.

I have purchased sensors and found a source that states I need a 2 conductor 22 awg solid core wire to connect the sensors to the motor.

Do I have the correct information as above? I have found a source for 2 conductor 22 awg stranded wire. Will the stranded wire work OK? The voltage is probably less than 24 volts.

Should the wire be shielded?

Thank you for your comments.

Just go to your local Big box store and they have rolls of the wire in the aisle that electrical wire is in. Also may have it in the area that the garage door openers are at.

Just standard Zip cord is used. Nothing exotic.

Just about any type will do, but I would stick to solid wire, it is much easier to work with in such a light gauge wire. The wire commonly used for doorbell wire works fine. Telephone wire or thermostat wire will work fine too. No shielding is needed.

Hopefully you purchased the correct sensor eyes for your model and brand of opener, they are different and have changed specs even within the same brand over the years.

I bought a large roll of cat5 cable which I use for all that little stuff. Comes in handy. Did my garage low voltage wiring with it... my alarm... even did my low voltage patio lights with it. Versatile and universal!

Thank you for your reply. I will go to either Lowes or Home Depot to get solid core wire. I have found the 22 awg 2 conductor is usually called Bell Wire.

I had a difficult time finding out which sensors I needed but the Sears online help line confirmed the type sensors I needed.
I need further help with connecting the sensors to the motor but will write another request for assistance.

The garage door manufacturer will state what sensors that need to be used with their opener. If unsure. Email or call them.

Use bell wire or T-stat wire. It also needs to have a CL2 rating.
