DETACT-T2 (DETector ACTuation - Time
squared) is a program for calculating the actuation
time of thermal devices below unconfined ceilings.
It can be used to predict the actuation time of fixed
temperature and rate of rise heat detectors, and sprinkler
heads subject to a user specified fire which grows
as the square of time. CT-T2 assumes that the thermal
device is located in a relatively large area, that
is only the fire ceiling flow heats the device and
there is no heating from the accumulated hot gases
in the room. The required program inputs are the ambient
temperature, the response time index (RTI) for the
device, the activation and rate of rise temperatures
of the device, height of the ceiling above the fuel,
the device spacing and the fire growth rate. The program
outputs are the time to device activation and the
heat release rate at activation. DETACT-T2 was written
in BASIC and FORTRAN by D.W. Stroup. |
