Kaiser HWD 90 Electronics Box

The Kaiser HWD 90 Electronics Box is a specialised fire protection cavity wall box designed to provide additional installation space for electronic devices, communications equipment and automation components within lightweight wall constructions.

The dual-chamber design incorporates an enclosed separator wall and provides capacity for both wiring and electronic equipment such as KNX actuators, relays, communication modules and other automation devices.

Utilising Kaiser AFS (Automatic Fire Stop) intumescent technology, the HWD 90 Electronics Box is supported by European fire testing and approvals for installation within fire-rated wall constructions.

European Testing & Approvals

The HWD 90 Electronics Box is supported by European fire testing, classifications and approvals for use within:

Fire-rated wall systems
Installation shafts and ducts
Timber frame constructions
Acoustic wall systems

Supporting technical documentation, approvals and fire test reports are available on request.

Australian Projects

The HWD 90 Electronics Box is particularly relevant where additional space is required for automation, communications and accessibility technologies that cannot readily be accommodated within conventional wall box systems.

Suitability for use within Australian projects should be assessed having regard to:

Wall construction type
Required FRL
Installation methodology
Project fire engineering requirements
Certification and approval requirements

Black Cat Control Systems can provide available manufacturer technical documentation and supporting test evidence. Assessment of the suitability of the complete wall system remains the responsibility of the project design team, fire engineer and certifier.
