As part of the standard, there is a relationship with the HVAC (Heating Ventilation Air Conditioning) system, that is, the standard AS1668.
Typically, HVAC is referred to as the “Mechanical Services” component of the Fire System.
Supply and Exhaust fans, which serve the air conditioning system for our indoor environmental control, become potential life saving equipment in “Fire Mode” where these fans are called to run to reduce smoke and provide fresh
air and oxygen into the building, reducing smoke inhalation and potentially saving lives.
With our HVAC / Mechanical services team we can provide the relevant maintenance and repairs to this part of the system in line with the Standards. There are many components between the Fire Control System and the Mechanical
Services System which interconnect and work together here, for example: During a given FIRE MODE, the mechanical services system: provides the Fire Stair pressurization equipment and control provides the Supply Fans for Fresh air
intake into the building will open or shut relevant Air Dampers via actuators can shut down fans where call upon by the Fire indication panel control system forces specific Fans to destruction when in Fire mode (Variable speed
drives)
