4. If the output is activated by one or more system
inputs, activate these inputs and verify that the
output priority function operates appropriately.
5. Confirm sequential operation for output modules
connected to fans, dampers, and doors.
Weekly testing of dedicated smoke control systems
1. Programming for the SCS must include a weekly test
of dedicated systems and their components.
2. Results of automatic testing should verify that all
components operate in the programmed sequence.
3. The program, at the designated time, must
automatically activate the output command for each
of the system inputs, verifying were necessary that
dampers (and other compartmenting components)
have opened or closed and fans have started or
stopped.
4. A record of the automatic test sequences and results
must be maintained at the location of the VM-1 SCS.
Dedicated systems
Zoned smoke control and atrium
systems
Verify the exact location of each smoke control zone and
the door or other openings in the perimeter of each
zone. If the building plans do not specifically identify
them, the smoke control system may have to be
activated in zones so that any magnetically held doors
will close and identify smoke zone boundaries.
For the building components verification, the component
designer should measure and record the pressure
difference across all smoke control zones that divide a
floor. The measurements should be made while the
HVAC systems serving the floor's smoke zones are
operating in their normal (i.e. non-smoke control) mode.
The measurements should be made while all smoke
barrier doors that divide a floor into zones are closed. A
measurement should be made across each smoke
barrier door or set of doors, and the resulting data
should clearly indicate the higher and lower pressure
sides of the doors.

Chapter 4: Smoke control acceptance and testing
Using smoke control input devices, verify the proper
activation of each zoned smoke control system in
response to all means of activation, both automatic and
manual, as specified in the contract documents. Where
automatic activation is required in response to alarm
signals received from the building's smoke control
system, each separate alarm signal should be initiated to
ensure that proper automatic activation of the correctly
zoned smoke control system occurs. Automatic weekly
testing of dedicated systems should be conducted to
verify all components operate as installed and
programmed and that the test time is agreeable to the
building owners. Verify confirming indications,
documenting the proper operation of all fans, dampers,
and related equipment for each separate smoke control
system zone.
Activate the zoned smoke control system that is
appropriate for each separate smoke control zone.
Measure and record the pressure difference across all
smoke barrier doors that separate the smoke zone from
adjacent zones. The measurements should be made
while all smoke barrier doors that separate the smoke
zone from the other zones are fully closed. One
measurement should be made across each smoke
barrier door or set of doors, and the data should clearly
indicate the higher and lower pressure sides of the
doors. Doors that have a tendency to open slightly due
to the pressure difference should have one pressure
measurement made while held closed and another made
when unrestrained.
Continue to activate each separate smoke control zone
and make pressure difference measurements. Ensure
that after testing a smoke zone it is properly deactivated
and the HVAC systems involved return to their normal
operating mode prior to activating another zone's smoke
control system. Also ensure that control verifying damper
and fan operation necessary to prevent excessive
pressure differences are functioning to prevent damage
to ducts and related building equipment. Component
testing should have previously verified operation of fans,
dampers, doors, and other smoke control equipment.
Stair tower pressurization systems
The building system designer, with all building HVAC
systems in normal operation, should measure and
record the pressure difference across each stair tower
door while the door is closed. After recording the
