Discuss TD-S2-BTD-S2-B residential lock brief: full-height fit and access fallback
TD-S2-B should be evaluated as a full-height residential lock with a measured door, access path, power and fallback. The model dimensions guide the review; the site decides the fit.
Checks before shortlisting
- TD-S2-B full-height dimensions 418 × 78 × 59 mm and 416 × 77 × 73 mm are checked against door and trim.
- The 4,200 mAh battery and 5 V Type-C emergency input are tied to the model revision and low-power test.
- Tuya account, credential, fallback and resident or staff workflow are separated.
- Mortise, backset, handing and clearance are recorded for the measured door.
- CE, UKCA and FCC files are matched to the exact TD-S2-B configuration.
- Sample door, pilot batch and repeat order are kept as separate gates.
- A 2026 or supplied revision is recorded alongside accessory and support owner.
Implementation and handover
- Survey the door, frame, full-height clearance, power and emergency route.
- Test lock, credentials, app, mechanical fallback, low power and recovery.
- Record firmware, account, permissions, spare and RMA workflow.
- Attach model dimensions, market file and acceptance evidence to the quotation.
- Close the sample-door exception list before expanding to a pilot or repeat order.
Risks to resolve before supply
- A full-height body can fit one door and fail another frame or trim condition.
- A current or battery field cannot replace an installed load and recovery test.
- A Tuya workflow does not define the emergency or mechanical fallback.
- A quantity release without the same revision can create inconsistent service cases.
Before requesting a quote
Choose TD-S2-B when full-height fit, access, power, fallback and document evidence pass the same staged gate. Share the selected model, configuration and destination market through the project RFQ route.
