Chapter 4: Smoke control acceptance and testing
Building test parameters
The following parameters need to be measured during
acceptance testing:
•
Total volumetric flow rate
•
Airflow velocities and direction
•
Door-opening forces
•
Pressure differentials and ambient temperature
Smoke control test parameters
The following parameters need to be confirmed during
acceptance testing:
•
VM-1 SCS component control
•
VM-1 SCS detection
•
FSCS override and component control
Building component testing
procedures
Prior to beginning acceptance testing, all building
equipment should be placed in the normal operating
mode, including equipment that is not used to implement
smoke control, such as toilet exhaust, elevator shaft
vents, elevator machine room fans, and similar systems.
Wind speed, direction, and outside temperature should
be recorded on each test day.
If standby power has been provided for the operation of
the smoke control system fans, louvers, or dampers, the
acceptance testing should be conducted while on both
normal and standby power. Disconnect the normal
building power at the main service disconnect to
simulate true operating conditions in this mode.
VM-1 SCS/FSCS test procedures
Smoke control acceptance testing should include
demonstrating that the correct outputs are produced for
each input of a control sequence specified.
Consideration should be given to the following control
sequences, so that the complete smoke control
sequence is demonstrated:
•
Normal mode
•
Automatic smoke control mode for first alarm
54
•
Second alarm annunciation without automatic
override of first alarm
•
Manual override of normal and automatic smoke
control modes
•
FSCS controls (where installed) override of all other
system controls
•
Return to normal
It is acceptable and desirable to perform acceptance
tests for the fire alarm system in conjunction with the
smoke control system. One or more device circuits on
the fire alarm system could initiate a single input signal
to the smoke control system.
A prepared smoke control system testing procedure
should be developed to establish the appropriate
number of initiating devices and initiating device circuits
to be operated to demonstrate the smoke control system
operation for the AHJ's approval. The section titled
"Other test methods" in this chapter contains additional
information on test methods which may come under AHJ
consideration for acceptance testing.
Initial acceptance testing for primary power supplies
The following steps are required for a VM-1 SCS.
1. Verify that all components are installed in workman
like manner.
2. Verify adequate separation between power-limited
and nonpower-limited wiring.
3. Verify that the installed batteries are the proper
capacity for the application including the FSCS
series graphic annunciators, where installed.
4. With the batteries disconnected, verify that the
supply's full alarm load can be sustained by the
power supply without the batteries connected.
(Temporarily jumper the positive battery terminal to
the positive auxiliary output to remove the battery
trouble.)
5. With the batteries connected, disconnect the AC
source and verify that a power supply trouble is
annunciated, and that the supply's full alarm load
can be sustained by the batteries. The full alarm
load may include the FSCS.
6. Verify that the battery charger properly charges the
batteries to 80% capacity within 24 hours.
