5G

by Roy Bardowell, CDDC

April of 2019, the very first 5G network was launched by Verizon. 5G, which stands for 5th generation, operates on a different scale than its predecessors, producing more electrical magnetic radiation.

Radiation is the emission (sending out) of energy from any source and can be harmful to humans. X-rays are an example of radiation, so is the light that comes from the sun and the heat that is constantly coming off our bodies.

Radiation exists across a spectrum from very low-energy (low-frequency) radiation to very high-energy (high-frequency) radiation. This is sometimes referred to as the electromagnetic spectrum.

Electrical magnetic radiation is ubiquitous meaning it is literally everywhere. In the safe comforts of your own home, you are walking through an electrical magnetic flux. First, we had short wave radio signals for the transmission of radio. Soon to follow, television signals were established. Before long every home had an antenna on the roof. Personally, I have never heard of any potential dangers associated with radio (RF) or television transmissions. But to be honest I didn’t really care because I enjoyed the entertainment television shows provided.

The fifth-generation network is more complicated. 5G operates within two frequency ranges on the electromagnetic spectrum, ranging from ultra-high frequency to extremely high frequency. The first is the frequency range below 6 GHz, the same range currently used by existing 2G, 3G and 4G legacy systems. This year, cellular network carriers will broadly shift to this version of 5G, the main benefits being increased data speeds and reduced latency.

Both the United States and Canada are investing billions of dollars to purchase spectrum in auctions and deploy 5G infrastructure between 2020 and 2026.

Still, the BIG question remains; Is 5G harmful to humans? Two big factors influence that answer- proximity and exposure time.

I think the question is bigger than “what does this technology do to our bodies”? Currently, new products are being developed to prevent the harmful effects 5G creates. Take for example, a new paint that is produced in Germany, capable of reflecting 5G rays. If you paint over a metal strip and connect the strip to an Earth ground the 5G radiation will be sent into the ground rendering it harmless. There will always be other places where 5G electromagnet radiation can enter your home, such as windows or doors. Surprisingly, steel garage doors containing an outside skin made from galvanized steel, will reflect the 5G waves back into the public domain. This may offer some comfort, but in builder’s communities, all the garage doors will be the same. Meaning your neighbors doors can bounce 5G waves back toward your home. This bouncing can happen between many homes at the same time. Unfortunately, there is not much we can do other than just accept the situation as progress and hope for the best.

    can my model 600SL be modified to accept the Guardian backup battery. If not, what rating of a plug-in stand alone backup battery should I purchase?

    Hi Jim,

    No, the model 600SL uses a 24V motor and BBU systems are 12V.  A battery backup operator will also require power managemnt circuitry.

    Hi Paul,

    myQ is not compatible with Guardian garage door openers.  The Guardian model V2 Smart Control Kit would be your best option to use to have this feature.

    Hi Thomas,

    First check to see whether the eyes have been properly wired into the operator head.  There are 4 terminals for photo-eyes.  All 4 must be used in order to provide full power to the eyes.  Lack of power can cause the blinking condition.

    A short in the photo-eye wires can also cause the green LED to blink.  Over time, expansion and contraction due to weather, can cause a staple to break the wire insulation. 

    See this link for more advice: https://www.adhguardianusa.com/technical-references-troubleshooting-photo-eyes

    Call Guardian Tech Service at 424-272-6998 for more advice.

    My green side is frequently blinking, so the door can't open/close. Lens are clean, no obstructions and we've tried adjusting the green side left/right, up/down with no luck. Sensor wiring appears secure. What am I missing??

    Hi Rick,

    Please call 424-272-6998.  The noise could be better described to a tech or he can be allowed to listen to it in order to better assess the issue.  Thanks

    Motor is making noise only when opening door. No noise on closing. Is this a motor lube issue or a replace motor issue? Any input appreciated.

    I bought a Guardian Garage Door opener and from day 1 it has been temperamental when using the remote to open and close. If i am too close or push the button to long or too short a time. I had the installer return and ask questions, it appears Guardian knows their problem is the RF signal being sent at too rapid a rate or something of the like.
    DOES GUARDIAN HAVE A SOLUTION TO CORRECT YOUR ISSUE? At present i would never recommend this product or ever buy another, my second door will not be replaced with a Guardian.

    We had a long power outage and when power was restored opener would not open. I pulled the red cord to open manually and now the opener doesn't work at all. It doesn't even seem to be connected. Do I just need to reprogram the opener? Thanks!

    Hi Jim,

    There are no stock sun shields for photo-eyes.  Fabricate a shiled from cardboard or an empty paper tube and tape to the red (receiver) photo-eye.  Another trick would be to reverse the position of the eyes, placing the receiver eye on the shaded side (if there is one eye in bright sun and the other in the shade). 

    You are right, both red and green LEDs should be steady.  The flashing green could be due to misalignment or a poor connection at the operator head.  First, check the PE alignment.  If necessary, remove the wing nut holding the sensor for full range of motion.  Next, check the terminal block on the back of the motor head.  The first 4 terminals (L to R) are for photo-eye wires.  Each terminal should have one wire inserted.  At times, installers twist together pairs of wires.  Not using all terminals cuts the ammoun of current avaialble to the sensor and could cause the LEDs to flash.  If these two steps do not work, call 424-272-6998.

    Hi Roy,

    Thank you for the blog. We have a Guardian Pro Series 628 which was installed about two years ago. We have constant problems with the sensors and believe this is cause by glare from the sun since we experience the problems mostly during the day. Are there specific safety sensor sun shields (that's a mouthful) that work with these units? Also, the green light on that side blinks slowly all the time but the door still goes up/down. Is that normal? I thought both lights should be solid.

    Thanks!

    Clinton,

    If you plug the photo-eyes that do not light-up when plugged into operator A into operator B and they light-up, the eyes are good.  Replace the logic boaed in operator A.

    Call 424-272-6998 for additonal assistance.

    I have no lights on my photo eyes. I have two garage door openers and tried the logic board in the other opener and the lights would come on. This tells me the logic board is good. Wondering if it might be the transformer.

    Hi Clinton,

    If the operator still opens the door and a constant pressure on the push button (PE override) closes the door, then the circuit board is probably not the problem.

    1. Check at the operator head to see if wires are in the 4 photo-eye terminals.  Sometimes installers will twist wires togther and use only 2 of the terminals.  This reduces power to the photo-eyes.  It may work initially, but over time as the wire develops more resisitivity, power declines.

    2. Check the alignment of the eyes.

    3. If LEDs fail to appear, after careful alignement, then replace the phot-eyes.

    4. Call 424-272-6998 for further help.

    The drive belt on my 3/4 HP Guardian executive series 600SL has broken. How do I get it fixed? I called your 800-989-8769 phone number and the phone company said the number is disconnected so no one answered

    Hi Sherri,

    Is the LED back light on the panel glowing?  Check the wiring first.  The plug on the end of the wire leading from the control banel should be securely plugged into the "wall box" recepticle on the motor head.  Check for any wire shorts due to staples holding the wire to the wall.  Check the wire terminal connections on the back of the panel.. If more help is needed please call 1-424-272-6998.

    Any Guardian remote control listed on the remote controls page on this website will work with any Guardian operator.

    If there are issues reaching technical service please feel free to contact a regional office (also listed on the website).

    I read the comment on how a clicker is not universal and will not work on guardian garage doors. Specifically could you please suggest one that will work? Your tech phone number is useless! I've left two messages and not received a return call yet and its been three days. No one ever answers either.

    Hello,

    My garage door motor is beeping every 15 minutes. Is this due to my remote battery being low or the motor being low? I'm having trouble locating a batter on the actual motor.

    Roy, I have six two button remotes, the black rubber inserts fall out and I have to use a small object to activate the opener. Would it be possible to send me five or six replacements. I would happily pay for them.

    I'm in New Zealand. If I can't source this for my Guardian 21230DL, I'll have to discard an entire garage door opener which works perfectly well just because it can't receive the signal from the remote.

    I looked for an internet sale on your website but couldn't find it.

    Considering that it will cost $800 to replace the whole door opener unnecessarily, I would really appreciate your help.

    Regards
    Shirley

    I recently posted complaining about the motor. I found a number for Guardian technical services online and as a last effort I called them. Technical services was great and helped me fix the problem fairly easily with directions over the phone. I’m impressed with corporate but still disappointed in the local installer as since the day they installed the opener they come across as more interested in generating charges than doing what’s right for the customer.

    Thanks to Technical Services!
