 HVACC: Emergency Shut-Down of Air Moving Systems

Re: Emergency Shut-Down of Air Moving Systems

HVAC Concepts, Inc. (HVACC) has been receiving many requests regarding the ability of your KPS Building Automation Systems (KPS) to shut down all air moving systems upon command from a workstation (terminal) or other manual input in the event of an emergency.

There are several issues regarding this concern that we would like to bring to your attention:

(1) It is important to understand that the KPS is not classified as a life/safety protection system! The KPS has the ability to shut down connected equipment to optimize energy consumption, but was never intended to provide life/safety protection. Users should understand that most KPS connections are wired in a manner allowing them to be easily overridden (bypassed) for service purposes, defeating the automatic functionality. Other KPS connections may be installed where other controls or safeties can force the connected equipment on or off. In contrast, a system designed for life/safety purposes is wired so it can never be bypassed or overridden.

(2) All ventilation systems are not normally connected to the KPS as they are designed to run constantly or come on automatically. Exhaust fans, specialized pressurization fans and other ventilation units would need to be considered in any attempt to lessen air infiltration into a building. Shutting fans down and closing dampers will reduce the amount of outside air infiltrating a building but would not eliminate it.

(3) HVACC is not aware of any formal codes from governmental agencies regarding chemical or biological attacks. Ashrae has released a set of guidelines "Building Health and Safety under Extraordinary Incidents". We also must make it clear that we are not experts in protecting buildings from these or other sorts of attacks.

HVACC can perform software and/or hardware modifications to accomplish a specific, customer designed, sequence of operation but cannot consult or advise any action or remedy to provide this type of protection as we do not possess the expertise required. Our only warranty on installations such as this is that we will service the equipment installed if it fails. HVACC will not assume any other liability installations or modifications that could be perceived as life/safety protection.

Although HVACC will test the sequence of operation thoroughly upon completion we strongly recommend that any such installation/modification be tested routinely to help ensure all equipment is operating as intended. We strongly urge you to seek a qualified, licensed consultant specializing in these areas.
