Dear Ms. Henzel:
In reference to the mechanical project at One Lincoln (MEC2006- 00465) in which stairwell
pressurization fans are being added to four stairwells, please note that all stairwell pressurization
fans will be activated upon any smoke detection by an automatic detector in the building's fire
alarm system. Programmable relay modules that are part of the fire alarm system will control the
fans. Deactivation of the stairwell pressurization fans will take place when the alarm condition
has been cleared and the fire alarm system has been reset. This will also be accomplished by
the building fire alarm system.
Please find the attached pdf files showing the operational matrix outlining control of the stairwell
pressurization fans and the riser diagram indicating the stairwell pressurization fan control
modules.
Please feel free to contact me with any questions you may have. Thank you.
