# Garage door opener installation > New openers fitted to a balanced door, with photo eyes, wall buttons, remotes and keypads set up right. Page: https://www.bluehengaragedoors.com/garage-door-opener-installation ## The short version Garage door opener installation means mounting a new opener, connecting it to a balanced door with the top section reinforced, setting the photo eyes no higher than six inches off the floor, placing the wall button at least five feet up, programming remotes and keypads, and adjusting travel limits and force. Blue Hen Garage Doors installs openers across Delaware and Maryland's Eastern Shore. ## Signs it's time for a new opener - No photo eyes or edge sensor, a likely sign of an opener built before 1993 - Repeated board or drive failures on an aging unit - Remotes that use old fixed codes instead of rolling codes - You want a wall-mount opener to free up the ceiling - A new door, or a door that never had an opener - No battery backup on a garage that's your main way in and out ## What has to be right before an opener goes on? The door has to be right first. DASMA's guidance for installers lists the checks: door sections free of fatigue, cracking or separation, warning labels in place, springs and hardware securely attached, springs contained by a shaft or a cable, handles or gripping points on both sides, and a door that moves freely and doesn't open faster than you lift it. Ropes come off, and manual locks get removed or disabled so the opener can't fight them. Two more checks matter. The top section must be reinforced both horizontally and vertically, or the opener arm can bend it, and the door must be level to the floor, because gaps keep the reversal systems from working across the full width. DASMA also says an opener should be installed only on a properly balanced and lubricated door, since an unbalanced door may not reverse when required. If the door fails any of these checks, that gets fixed first. ## Chain, belt, screw or wall-mount: which drive is right? Most openers hang from the ceiling and pull a trolley along a rail, and the drive is what pulls it. A chain drive uses a chain like a bicycle's, a belt drive uses a rubber belt in its place, and a screw drive turns a long threaded rod inside the rail. Direct-drive units put the motor in the trolley itself and run it along a fixed chain. All of them connect to the top of the door with an arm and release from it with a pull cord on the trolley. Wall-mount jackshaft openers skip the rail and turn the torsion spring shaft directly, which frees the ceiling for storage, a lift or high-lift track. They need a torsion shaft to mount to, and on standard-lift track they need extra provisions to keep the cables tight; DASMA's guidance lists track pitch, push-down springs, cable keepers and cable tension monitoring, and it advises checking with the door and opener makers before using one with low-headroom track. Ceiling height, track type, door size and how you use the space all factor in. ## Where do photo eyes, wall buttons and the manual release go? Photo eyes go low and close to the door. DASMA's sheet on sensor placement says the beam must be no higher than six inches above the floor and the sensors should sit within six inches of the door's path. The federal standard for residential openers, 16 CFR 1211, covers every unit made on or after January 1, 1993, and requires a downward-moving door to start reversing within 2 seconds of hitting an obstruction. The wall button goes at least five feet above the floor, in sight of the door and away from its moving parts, so small children can't reach it, with the entrapment warning label posted next to it. The red manual release handle should hang about six feet up, where you can reach it without it snagging a car. On new construction, DASMA and IDA publish a pre-wiring layout for builders that brings the photo eye wires out about six inches above the floor. ## Remotes, keypads, rolling codes and battery backup New remotes and keypads get programmed to the opener at install, and old or lost ones can be cleared out. DASMA explains that rolling-code transmitters change their code after every use, so a thief who records your signal can't replay it later; older fixed-code systems could be beaten by exactly that kind of record-and-replay trick. DASMA also advises keeping remotes away from children and locking the car if a remote rides in it outside. Battery backup keeps the door working when the power is out. DASMA recommends it where outages are common and says the backup battery will need replacing after 2 to 5 years, depending on use and type. With Delaware's nor'easters and summer thunderstorms, it's worth considering if the garage is your main way in and out, especially for anyone who can't lift a door by hand. To test it, unplug the opener and run the door from the wall button, as DASMA's checklist describes. ## How do you match an opener to the door? Match the opener to the door's size, weight and daily use, not to the biggest number on the box. Because the springs carry the weight, a properly balanced residential door doesn't need an oversized motor, which is why DASMA's opener tips steer owners of heavy doors toward balancing rather than a stronger opener. A tall carriage house door or a door that runs many times a day still deserves an opener rated for that work, and DASMA's terminology separates continuous-duty motors, rated to run under load without overheating, from intermittent-duty units with a maximum number of cycles per hour. Detached garages and barns raise other questions: power at the opener, distance from the house for remote range, and whether the door has torsion springs for a wall-mount unit. When the job is done, keep the opener's manual near the door. DASMA recommends hanging the door and opener manuals there, since every model has its own safety instructions. ## From the call to a working door 1. Call (302) 735-0046 and tell us about the door, the ceiling height, and whether the springs are above the door or along the tracks. 2. We check the door's balance, condition and top-section reinforcement before anything is mounted. 3. We walk through drive types, mounting options and features, and recommend an opener that fits your door. 4. We install the opener, photo eyes, wall button and keypad, program your remotes, and set travel limits and force. 5. We run the photo eye test and the 2x4 auto-reverse test and leave the opener's manual with you. ## Questions ### Can I put a new opener on my old door? Usually, if the door passes the checks: solid sections, secure springs and hardware, contained springs, a reinforced top section, a door level with the floor, and good balance. If it fails, the door gets fixed first. DASMA says an opener should go only on a properly balanced and lubricated door, and a new opener on a door that's out of balance wears out early and may not reverse when it should. ### Is a wall-mount opener right for my garage? It can be, if the door has a torsion spring shaft to mount to. Wall-mount jackshaft openers free the ceiling, which helps with storage, a car lift or high-lift track. On standard-lift track they need ways to keep the cables taut, like pitched track, push-down springs, cable keepers or tension monitoring, and DASMA advises checking with the manufacturers before pairing one with low-headroom track. ### Why are the photo eyes mounted so low? So a small child can't crawl under the beam. DASMA says photo eyes should never be installed higher than six inches off the floor, and the bottom beam of any multi-beam setup follows the same rule. Mounting them higher to protect a car bumper defeats their purpose. If yours sit higher, or have been knocked out of line, they should be reset. ### Do I need battery backup on my opener? It's worth it if the garage is your main entrance or you'd struggle to lift the door by hand. DASMA recommends battery backup where power outages are common and notes the battery needs replacing after 2 to 5 years depending on use and type. Test it now and then: unplug the opener and run the door from the wall button or remote. ## Related - [Garage door opener repair](https://www.bluehengaragedoors.com/garage-door-opener-repair) - [New garage door installation](https://www.bluehengaragedoors.com/garage-door-installation) - [Garage door tune-ups and maintenance](https://www.bluehengaragedoors.com/garage-door-maintenance) ## Sources - [DASMA TDS-369: automated residential garage door FAQ](https://www.dasma.com/wp-content/uploads/pubs/TechDataSheets/OperatorElectronics/TDS369.pdf) - [DASMA TDS-364: where photo eyes go](https://www.dasma.com/wp-content/uploads/2026/07/TDS364.pdf) - [DASMA TDS-167: door and opener checklist](https://www.dasma.com/wp-content/uploads/2023/04/TDS167.pdf) - [DASMA Technical Data Sheet 385 (January 2024) (PDF)](https://www.dasma.com/wp-content/uploads/2024/05/TDS-385-January-2024.pdf) - [DASMA Technical Data Sheet 362 (PDF)](https://www.dasma.com/wp-content/uploads/2025/05/TDS362.pdf) - [DASMA Technical Data Sheet 350 (PDF)](https://www.dasma.com/wp-content/uploads/2026/07/TDS350.pdf) - [DASMA Technical Data Sheet 1501 (PDF)](https://www.dasma.com/wp-content/uploads/2022/12/TDS1501.pdf) - [DASMA safety tips: garage door openers](https://www.dasma.com/safety-tips/garage-door-openers/) - [DASMA safety tips: garage door systems](https://www.dasma.com/safety-tips/garage-door-systems/) - [16 CFR Part 1211: federal safety standard for garage door openers](https://www.ecfr.gov/current/title-16/chapter-II/subchapter-B/part-1211) - [Wikipedia: Garage door opener](https://en.wikipedia.org/wiki/Garage_door_opener) - [Delaware Climate Office: Delaware's climate](https://climate.udel.edu/delawares-climate/) ## Contact Blue Hen Garage Doors, 110 Lafferty Ln, Suite F, Dover, DE 19901.
