SonSec Technician's Notes
Start with the gate condition, track quality, roller condition, rack line and safety equipment before specifying the motor.
SonSec Verdict
SonSec recommends the D20 SMΔRT+ for heavy gates and more demanding sites where a larger capacity margin is required.
Ideal For
Heavy sliding gates that still run smoothly by hand.
Sites that need the strongest standard SMΔRT+ capacity in the range.
Commercial and estate entrances where margin matters more than compact size.
When Not to Choose
Do not choose it for light domestic gates that do not need the extra capacity.
Avoid it when the site wants a faster small-gate solution rather than a heavy-duty one.
Skip it if the gate mechanics are poor enough that repair should happen first.
Things to Consider
Heavy gates deserve a clean, straight track and correctly aligned rack.
Plan safety devices, access control and backup support from the start.
Leave enough room for future servicing because heavier sites usually need more maintenance access.
Installation Notes
Confirm the gate is mechanically sound and rolls freely before installation begins.
Set the rack and motor position carefully to avoid binding under heavy load.
Commission safety devices only after the full travel path is verified.
Maintenance Notes
Heavier gates need routine inspection of the track, rollers and rack line.
Test remotes, beams, manual release and battery performance at every service.
Treat changes in travel sound, speed or stopping behaviour as early warning signs.
Service Life Expectations
On a well-balanced gate, regular servicing helps the D20 remain dependable for a long time.
High traffic, extra weight and rough tracks shorten maintenance intervals and increase wear.
Battery, charger and accessory checks remain important on every service visit.

FAQs
Is the D20 the heaviest option in the verified range?
Yes. It is the strongest standard SMΔRT+ choice in the current verified line-up.
Should the D20 be used on a rough gate to make it work better?
No. The gate should be mechanically sound before any operator size is specified.
What should be checked first on a heavy gate?
Gate balance, track condition, roller wear, rack alignment and power quality should be reviewed first.
Common Faults
Heavy gate feels sluggish or strained.
Inspect track resistance, rollers, rack alignment and gate balance before adjusting controller settings.
The gate reaches end travel with a heavy sound.
Check end stops, pinion mesh and the gate’s mechanical condition first.
Access command is delayed or unreliable.
Review receiver wiring, remote batteries, access-control programming and controller inputs.
Backup performance drops under load.
Battery age, charger health and accessory load should be checked before replacement is considered.
Service & Maintenance
- Confirm the exact product model and installed accessories before service work.
- Check power, battery condition and wiring before replacing control equipment.
- Use official manufacturer documentation where a product-specific setting or procedure is required.

Compare With
Compare with D10 SMΔRT+
