    Smoke barriers

    Smoke barriers divide a space into several smaller smoke zones. These are then easier to ventilate using a smoke and heat exhaust ventilation system.

    Smoke ventilation

    Smoke and heat exhaust ventilation minimises property damage, makes it easier for firefighters to intervene and gives people enough time to leave the building safely.

Optional extras

  • 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.
  • 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.
  • 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.
  • 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.
  • HS “High Speed”
    In smoke ventilation mode, the high-speed function is used to reach the defined end position reliably within 60 s. In daily ventilation mode the drive runs quietly and quickly, as usual.
