    Default Garage Door Auto Close - Wants Safety Beams Installed.

    Hi all,
    As you know I recently had a new garage door fitted and the suppliers, B&D Doors have a Safety Beam option for $200.

    Not wanting to go down that Laser kit that vnboost linked to (Requires minimum 10VDC);


    The door has an auto close function of which I would like to work. However, it requires the Safety Beams (SB), to be installed!

    On the back of the unit it has a SB and GND connections. When the door is closed it is Zero Volts. When opening it is dead on 5 VDC and when fully Opened is goes back to Zero after about 2 seconds. When closing it is at 5VDC, then back to Zero after 2 seconds.


    I'm wondering if there is a way to trick the Hub to think it has the SB installed?








    There are/is OSC terminals below the SB - (of which my manual doesn't mention - but an older model manual does).
    * Safety Beam Failure Emergency Close
    When a safety beam prevents movement due
    to any reason other than a ‘real’ obstruction, the
    user can secure their property by pressing and
    holding a button on the remote control or OSC
    on the console. *

    Cheers,
    GT250.

    i wouldnt bother with that function , i would never leave a closing door unsupervised at any time to begin with. the safety beam only monitors the bottom 300mm of space , and there are plenty of opportunities for kids or pets taller than that to jam something in the track and cause an injury long before the door reversed back up.

    VV,
    No kids here, no pets.
    Just me (at the moment), the missus (Partner), is stuck in the UK and can't get back in.

    I understand the 'what if concern'.
    I have tested the door by already, as it was closing using my hand it didn't seem a lot to stop it.
    I know it's hard for me to explain how much force i used to stop it, but it wasn't a lot IMO and actually surprised me.
    Maybe there's inherent (downward force), regulations - anyway - to prevent crushing children accidently, in case the buyers can't afford the $200 optional extra?

    The entire door weighs 80kg the motor is a 'loaded' 400N. I don't know if that's a lifting or closing capacity - maybe both.

    When it stopped it auto reversed.

    you could possibly try a magnetic reed switch. should work on the same principal. 2 wire in SB and GND. as long at the magnet connection isn't broken it should work.
