ES200 electric mechanical lock - Pulley with integrated locking and belt tensioning

This locking device is an electric controlled mechanical lock for ES 200 automatic sliding door opener. It combines the functions of pulley, belt tension and lock.

ES200 electric mechanical lock by Sanway Technology is perfectly working on original Dorma ES 200 & ES 200 Easy sliding door.

Key Specifications

• Product Name: ES200 Electromechanical Locking Device — also referred to as ES200 Electro Mechanical lock, ES200 Electric lock, Dorma ES200 Electric Lock; commonly cross-referenced in parts lists as 4000105 DORMA.

• What it does: An electronically controlled mechanical lock integrated inside the ES 200 header, combining (1) the return pulley, (2) belt tensioning, and (3) positive mechanical locking in one compact module.

• Fail-secure behavior: Designed to lock when power is off and unlock under controller command during opening cycles.

• System Compatibility: Built for DORMA / dormakaba ES 200 and widely used with ES 200 EASY; aligns with ES 200 controller logic and program modes.

• Installation location: Fits at the return-pulley side of the ES 200 header; interfaces with the belt path and the operator’s modular mechanics.

• Controller integration: Works with ES 200 Basic Module (BM) / Function Module (FM) architecture and standard mode set (Automatic, Partial, Exit-Only, Permanent Open, Night/Bank).

• Standards context (operator level): ES 200 platforms are documented to EN 16005 / DIN 18650 with modular components for quick install, commissioning and maintenance.

• Special note for escape-route variants: ES 200-2D doors typically require a lock with status (feedback) contact for monitored safety.

• Use cases: Professional upgrade or replacement for commercial dormakaba sliding door installations in retail, healthcare, transport, hospitality and corporate facilities.

FAQ

Q1. Is this the right lock for my Dorma ES200?
A. Yes. This is the ES200 Electromechanical Locking Device specified for ES 200 headers. It integrates pulley + belt-tension + mechanical locking and is managed by the ES 200 controller during opening/closing cycles.

Q2. Does it also fit ES 200 EASY?
A. In most projects, yes. ES 200 EASY shares the ES 200 platform architecture; installers routinely pair the same lock family with EASY headers. Confirm your header geometry when ordering.

Q3. How is this different from a “DORMA Electro Magnetic Lock” (maglock)?
A. A maglock mounts to the leaf/frame and holds magnetically. The ES200 Electromechanical Locking Device sits inside the header and mechanically blocks the drive via the pulley/tensioner assembly. This yields cleaner sightlines, precise alignment, and less visible hardware on glass doors.

Q4. What happens on power loss?
A. The lock is fail-secure: it remains locked when power is off. Once power and a valid open command are present, the controller releases it and drives the leaf normally.

Q5. Which part number should I quote?
A. Many distributors list this device as 4000105 DORMA. Match by photo/geometry to your header for certainty.

Q6. Do I still need a separate tensioner or pulley?
A. No. This module incorporates the idler/pulley and belt tensioning; it replaces separate components and simplifies service.

Q7. Will this change my door’s certified weight rating or standards compliance?
A. No. Ratings and compliance are governed by the operator platform and installation. A correct ES200 lock helps maintain secure closing and supports EN 16005 / DIN 18650 commissioning when used with approved sensors and procedures.

Q8. Do escape-route (ES 200-2D) doors need anything special?
A. Yes. 2D systems typically require a locking device with feedback contact for monitored safety; confirm with your authority having jurisdiction.

Q9. Any practical setup tips after installation?
A. After mounting, set belt tension per spec, verify end stops, then run the learn/commissioning routine from the controller. Test lock/unlock in Automatic, Partial, Exit-Only, and Night/Bank modes.

Product Description

When customers or staff tug on a closed sliding entrance, you want a lock that holds with confidence yet disappears visually. The ES200 Electromechanical Locking Device does exactly that for DORMA / dormakaba ES 200 operators: it locks the drive itself, inside the header, using a mechanical blocking element that’s built into the return pulley and tensioner module. Compared with surface-mounted maglocks, this integrated approach keeps your glass clean, reduces tamper points, and ensures the lock engages on the exact axis of motion—where it’s strongest and quietest.

From a facility manager’s viewpoint, the advantages are practical and immediate:

• Cleaner architecture, fewer parts. Because the lock also is the pulley and tensioner, you eliminate separate idlers and standalone tension hardware. Fewer components mean fewer failure modes, faster installs, and shorter service calls.

• Fail-secure by design. In a power outage, the door stays locked—a requirement for many retail and healthcare security policies. Once power and a valid command return, the controller releases and drives open without manual intervention.

• Predictable commissioning. The ES 200 controller handles the timing of lock release vs. motor start, so stopping points are consistent and Night/Bank schedules behave exactly as programmed—no guesswork with adhesive armatures or misaligned keepers.

• Quieter entrances. Integrating the lock within the belt path lets the manufacturer tune belt tension and harmonics inside the header, contributing to the ES 200’s reputation for quiet travel in premium lobbies and clinics.

• Standards-ready. Installed as part of an ES 200 system with compliant sensors/edges, the entrance can be commissioned to EN 16005 / DIN 18650 targets; documentation and parts traceability remain within the OEM ecosystem.

How it works

1. Return pulley: routes the toothed belt at the non-motor end of the header for a compact belt path.

2. Tensioner: sets precise belt preload so acceleration and braking are smooth and slip-free.

3. Mechanical lock: a controller-managed mechanism blocks rotation/motion at the pulley when the door must be secured—either on schedule (Night/Bank), on command, or by default when power is off.

Because the lock is controller-managed, your access control system sends a single open command; the controller sequences unlock → drive and monitors position/force as usual. You avoid the “two-box” complexity of wiring an external maglock to release slightly before the operator runs—reducing commissioning time and callbacks.

Buyer guidance

• Confirm your platform. Check the header label for ES 200 or ES 200 EASY. If you operate a 2D (escape-route) version, specify the lock with status feedback contact as required.

• Match by geometry. A quick photo inside the header—showing your current pulley/tension assembly—lets our team confirm fitment in minutes.

• Plan your scope. If the belt shows glazing or tooth damage, add a belt replacement to pair with the new lock/tensioner module for best results.

• Commission methodically. After mechanical install, set belt tension, verify end stops, then run the learn routine and test lock behavior in all modes.

Who benefits most

• Retail & malls: Fail-secure protection during outages; concealed hardware preserves storefront aesthetics and reduces tamper risk.

• Healthcare & pharma: Clean visuals around glazing; controller-timed locking supports pharmacy or Night/Bank schedules with audit-friendly behavior.

• Transit & hospitality: High-cycle reliability with fewer exposed parts; integrated design keeps public-facing elements minimal and robust.
