Frequently Asked Questions
What makes the ACK4 RWA suitable for smoke and heat exhaust?

The ACK4 RWA complies with the EN12101-2 directive for smoke and heat exhaust ventilation systems and runs at 24V DC, a typical requirement of RWA applications powered by a dedicated control unit.

Does it keep the same mechanical performance as the standard ACK4?

Yes: thrust force 300 N, maximum stroke 400 mm adjustable to 7 positions and stainless steel double-link chain remain unchanged, as does the IP55 protection rating.

Is it synchronisable and how does it signal an incorrect installation?

On request the S version for synchronising several actuators on the same window is available. The electronics have an acoustic buzzer to signal incorrect installation. CE marked.
