KA 54

POWERFUL UNIVERSAL CHAIN DRIVE 24 V

Category:

Smoke ventilation

The big brother of the KA 34: exceptionally flexible and universally applicable, just as robust and reliable, but the KA 54 chain drive for smoke and heat exhaust ventilation is significantly more powerful, with a force of up to 500 N. It is particularly suited to surface mounting.

Features

Can be used for smoke exhaust openings, D+H Euro SHEV to EN 12101-2, and for daily ventilation.
With microprocessor-controlled motor electronics
High-speed function (HS) for exceptionally fast window opening in the event of fire (SHEV).
Special chain stabilisation
Push applications up to 700 mm, tensioning strokes >1000 mm can also be used
Pressure relief on the window seal after the closing process
Programmable drive functions and various drive parameters
Travel speed in the CLOSE direction drops to 5 mm/s (passive closing edge protection)
Timed reversing when an obstacle is detected in the CLOSE direction (active closing edge protection).
Available in any RAL shade
Can be used for practically all types of window openings
The drive is suitable for surface mounting on the window sash or frame
Thanks to universal brackets, the drive is compatible with almost all available types of system profiles incl. Aluprof, Colt, Gutmann, Heroal, Jet-Brakel, Raico, Reynaers, Sapa, Schüco, Skandinaviska, Technal, Wicona

Optional extras

Function programming
The option of configuring drive parameters (e.g. the stroke) individually using software and the related service tools, for drives fitted with PLP, BSY or BSY+ electronics.
BRV signal
Confirmation from the drive, via the control cable, that the drive has fully extended or retracted. When used with the AT 41 and ERM 44 modules, this signal is sent to the central building management system, to the modules themselves or to the locking drive. The BRV signal is not potential-free.
SGI signal (position reporting)
In combination with the D+H servo plug-in unit SE 622 or the BSY gateway BSY-GW-024-010-U, drives can be controlled with precise positioning.
End position signal (OPEN / CLOSED)
Feedback from the drive via an integrated potential-free switching contact. It is given when the chain drive or linear drive has fully extended or retracted.
SBU (bendable chain)
The drive chain with a rigid back bends in the direction of the hinges. The drive is fixed in place (it does not pivot).
SBD (bendable chain)
The drive chain with a rigid back bends in the direction of the hinges. The drive is fixed in place (it does not pivot).
