Holyoake HFS motorised fire, smoke, and combination fire and smoke dampers, impede the spread of fire and smoke through ducted air systems whilst maintaining barrier integrity. Self-contained as fire and smoke dampers and externally operable by a spring return actuator. The HFS damper offers supreme fire and smoke leakage performance due to the unique patented sealing system.
HFS Fire and Smoke Dampers Rating
HFS leakage-rated, fire and smoke dampers have undergone rigorous testing in accordance with AS 1530.4:2014 and AS 1530.7:2007; comfortably meeting the stringent leakage integrity rates of 11.6.2.1. The damper is thereby aligned with the European ISO Standard 10294-1 ‘S’ Classification accordingly.
In fire rating tests conducted according to Standard AS 1530.4:2014, HFS fire and smoke dampers demonstrated exceptional integrity for over 4 hours. Compliant with the Australian Construction Code and New Zealand Building Code; they hold an impressive Fire Resistance Level (FRL) or Fire Resistance Rating (FRR) of -/240/-, making them a trusted choice for fire and smoke safety in your projects.
The IBD-FS dampers achieve an impressive Fire Resistance Rating (FRR) of -/240/- when installed in masonry walls/floors.
In addition to this these dampers achieve -/120/- in plasterboard walls, timber-framed floors, metal framework floors, Korok, and Hebel systems.
