Garage Door Sensors Dry Contact
The legislation was put in place requiring garage door sensors to be placed on every garage door in 1993.
Garage door sensors dry contact. Cycle the garage door through the opening and closing actions using the control on the garage wall. The replacement safety sensors project an invisible light beam across the inside of the garage door to prevent accidents and are required for safe use of all chamberlain garage door openers. This series iii dry contact adapter has been developed as a solution for openers that use series iii technology making it possible to use common on off switched inputs when required with these garage door openers. While it can be used as a momentary relay to open close the garage door the dry contact sensors used to determine door status cannot be read by the wink hub.
If you find the lights turned off in one or both the sensors it indicates that there is a problem in power supply. This piece goes in between the switch and the series iii wall console input. The dry contact adapter is compatible with genie and overhead door series iii model garage door openers. Or maybe you could wire up an optex beam unit which has a dry contact output typically and get the same result.
But how do the sensors work. All of this is in theory of course. High quality rigorously tested and durable only liftmaster parts are recommended for repairing your garage door opener. The units are placed near the ground on.
From logic boards to chain kits to safety reversing sensors find the right liftmaster replacement part to help you with any garage door opener repair project. The adapter is installed between the push button and garage door opener push button wire terminals. It is necessary to use a dry contact adapter when installing the aladdin connect kit to a genie or overhead door series iii garage door opener. Then check on the back of your button as there may be a resistor that puts a certain voltage on the line since other models may have a button for the door and light but use the same board in the unit.
Whenever there is an obstruction the garage door will automatically reverse before causing any damage. Look for small led lights on the sensors. But this isn t a problem as long as you have an alternate method to evaluate the open close status. A common cause of a malfunctioning garage door sensor is lack of power supply.
I would check to make sure you aren t in the ports for the sensor accidentally. Remove any debris dust or cobwebs from the electric eye lenses on each sensor with a clean rag. How does the system know there is something blocking the way. Garage door sensors utilize a photo eye sensor and a beam of infrared light that goes between the two units.
If there is a receiver that has a form c dry contact output you could use it to interrupt the wiring on the existing gdo safety sensors causing a fault and the gdo to not operate.
