D+H Window Automation NZ
Specialty Drives
Dedicated D+H drives for automated multipoint window locking,
door operation, heavy-duty openings and skylights where a
conventional chain or rack-and-pinion drive is not the
appropriate solution.
Special-purpose drives supported by EBSA
EBSA New Zealand supplies and supports D+H specialty drives for
specific window, door, roof-opening and building automation
applications.
The range includes powered multipoint locking drives that
synchronise with compatible D+H opening actuators, dedicated door
drives, heavy-duty drives and purpose-designed skylight drives.
These products are selected as part of a complete operating
system. EBSA reviews the opening type, geometry, load, mounting
arrangement, control sequence, interfaces, programming and
commissioning requirements before confirming the appropriate
drive solution.
Specialty drive range
Window Locking Drives
D+H FRA and VLD locking drives provide powered operation of
compatible multipoint window locking systems.
Through D+H BSY+ communication, the locking drive synchronises
with compatible D+H chain drives so the multipoint lock is
released before the sash opens. During closing, the lock does
not re-engage until the opening drive confirms that the sash is
fully closed.
- FRA 11-BSY+ rotary locking drive
- VLD 51/038-BSY+ linear locking drive
- VLD-0600-038-1-BSY+ linear locking drive
DDS 54 Door Drive
The D+H DDS 54 is a dedicated actuator for compatible automated
door-opening applications.
Selection depends on the door arrangement, required movement,
operating force, mounting position, control sequence, access
requirements and safety measures applying to the complete
automated door system.
SHD 54 Drive
The D+H SHD 54 provides a specialist operating solution for
compatible heavy-duty window, flap and building-opening
applications.
EBSA reviews the opening geometry, operating load, required
movement, mounting arrangement and controller requirements
before confirming suitability.
SDS Skylight Drives
D+H SDS 2 and SDS 3 drives are purpose-designed for compatible
skylight and roof-opening applications.
The drive, brackets, skylight construction and control system
must be coordinated so the required opening movement is achieved
without imposing unsuitable loads on the sash, hinges or
surrounding structure.
- SDS 2 skylight drive
- SDS 3 skylight drive
Automated multipoint window locking
FRA and VLD drives are primarily used to automate compatible
multipoint window locking systems.
A multipoint system uses an internal gearbox, connecting rods or
sliding locking bar to operate several locking points around the
sash perimeter. These may include locking cams, rollers, bolts,
shoot bolts or other compatible hardware.
Powered locking allows all locking points to be released and
secured automatically as part of the complete window-opening
sequence.
BSY+ locking and opening sequence
D+H BSY+ communication coordinates the locking drive with
compatible D+H chain drives and other opening actuators.
- An open command is issued to the window system.
- The FRA or VLD drive releases the multipoint locking hardware.
- The locking drive confirms that the sash is unlocked.
- The D+H chain drive is then permitted to open the window.
- When a close command is issued, the chain drive closes the sash first.
- The locking drive waits for confirmation that the sash is fully closed.
- Only after receiving that confirmation does the locking drive re-engage the multipoint lock.
This sequence prevents the opening drive from attempting to move a
locked sash and prevents the locking hardware from engaging before
the window has reached its fully closed position.
Why powered multipoint locking may be required
Perimeter locking
Several locking points can be operated automatically around the
sash perimeter rather than relying on the primary opening
actuator alone.
Sash compression
Compatible multipoint hardware can provide consistent
compression of the sash against perimeter seals after the
window has closed.
Coordinated operation
BSY+ communication provides the correct unlock-open-close-lock
sequence with compatible D+H opening drives.
Concealed hardware
FRA and VLD drives can operate compatible internal gearboxes,
connecting rods and sliding locking bars incorporated into the
window system.
System design and drive selection
Specialty drives should be selected around the complete operating
requirement rather than from the actuator model alone.
Opening geometry
EBSA reviews the sash, door or skylight movement, hinge
position, required opening angle, available space and actuator
connection point.
Operating load
The drive must account for weight, seals, friction, hardware
resistance, wind effects and changing geometry through the
operating cycle.
Control sequence
Locking, opening and closing functions must occur in the
correct order and coordinate with the selected D+H drive
electronics and control panel.
Safety and access
The design must consider accessible closing edges, trapping
hazards, maintenance access, emergency operation and the
intended use of the opening.
Natural ventilation and smoke control integration
Specialty drives may form part of natural ventilation, smoke
ventilation or smoke control systems. In these applications, the
actuator is one component within the complete operating
arrangement.
- D+H natural ventilation or smoke control panels.
- Compatible D+H chain drives and opening actuators.
- Multipoint locking and opening sequences.
- Fire alarm and building management system interfaces.
- Window, door or skylight position monitoring.
- Weather sensors and automatic close functions.
- Battery-backed control systems where required.
- Field wiring and cable-pathway coordination.
- D+H programming and commissioning.
Suitability for smoke control depends on the complete opening,
actuator arrangement, control system, interfaces and project
requirements.

Frequently asked questions
What is a specialty drive?
A specialty drive is an actuator designed for a particular
operating function that is not adequately served by a conventional
window chain drive or rack-and-pinion drive.
This category includes multipoint window locking drives, door
drives, heavy-duty drives and skylight drives.
Does a locking drive open the window?
No. The locking drive operates the multipoint locking hardware.
A separate compatible D+H chain drive or other opening actuator
moves the sash.
How does the locking drive work with a D+H chain drive?
Through D+H BSY+ communication, the locking drive releases the
multipoint lock before the chain drive is permitted to open.
During closing, the locking drive waits until the chain drive
confirms that the sash is fully closed before engaging the lock.
Why would an automated window need a locking drive?
A locking drive may be required where several locking points must
be released before the sash opens and re-engaged after it closes.
Compatible multipoint hardware may also provide perimeter
compression, weather sealing and secure closure.
Can several locking drives be installed on one window?
Yes. Up to four compatible FRA 11-BSY+ drives or up to six
compatible VLD BSY+ drives may be used on one window, subject to
the hardware arrangement, addressing, opening drives and complete
system design.
Can EBSA provide the complete control system?
Yes. EBSA can assist with specialty drives, compatible opening
actuators, D+H control panels, interfaces, sensors, operating
devices, programming and commissioning coordination.
Can specialty drives be used on existing openings?
Potentially. Retrofitting depends on the existing opening,
hardware, mounting space, operating condition, wiring and
controller arrangement.
EBSA can review drawings, photographs and installed model
information before confirming a replacement or retrofit pathway.
Are SDS 2 and SDS 3 general-purpose window drives?
No. They are specialist drives intended for compatible skylight
and roof-opening applications.
