Site Layouts and Measurements
Planning of fire protection zones and relevant FAAST system
locations are needed to begin the planning process. The plan
should include measurements of the area to be protected and
any areas designated for a different use. The plan should also
show any obstacles to the flow of air in the space, i.e. partitions
or other large objects. Areas requiring special protection should
also be noted.
Locations of large machinery, equipment, cabinets or any other
large items that may affect the pipe network design also need to
be identified on the plan.
Site Details
When designing the FAAST system, there are a number of site
details that need to be taken into account:
• Air flow and the location of air handling units, returns,
exhaust systems, etc.
• Construction of areas being monitored – high ceilings,
ceiling and floor voids, soffits
• Obstructions to pipe layout – beams, walls, furniture, etc.
• Placement of equipment requiring any special protection
– electrical cabinets, etc.
• Monitoring requirements – on-site, remote
• Activities within the environment – public space,
office space, clean room, warehouse, etc.
• Room temperature of the area being monitored and the
area where the detector will be located.
• Pressure differentials of each area if monitoring multiple
rooms with one detector.
Environmental Conditions
Identify any ambient conditions that exist within the protected
area. Typically different areas have different conditions. This
includes information such as temperature, humidity, and altitude.
The more accurate the information about the protected areas,
the better the FAAST system can be designed to meet those
needs.
The environment, both internally and externally of the protected
environment (especially if air is being pulled in for heating or
cooling), may have an effect on the operation of the FAAST
detector. Areas with high air movement can cause unwanted
pressure differentials across the FAAST device if the device
is not plumbed properly. High pollution levels may cause
background levels of particulate matter in the protected area.
The Acclimate feature of the FAAST system helps to
compensate for this background level. This setting may be
chosen during configuration of the FAAST device. If the
environment is better defined by days of the week, the FAAST
detector offers a day/night/weekend mode.
In locations that are normally subjected to difficult environmental
conditions, such as loading docks or warehouse spaces,
the FAAST detector is typically located within a controlled
environment, while the pipe network is located in the harsh
environment. In such applications the exhaust piping shall return
to the area being monitored.
System Design
PipeIQ is designed to take the information gathered during this
initial phase and assist in designing the pipe network. There
are two design methods within the PipeIQ software. One offers
a design wizard to create a simple layout based on the
parameters provided. The other allows for customization
throughout the process. Both methods provide the opportunity
to go back and modify the system as needed to accommodate
the environment being protected.
