Notes:
Response times and field of view data were derived by testing the device with a 1 ft
cup of heptane on top of a 1-in. layer of water was ignited for each test. These are typical values. The
variation of each fire can cause different results.
The field of view as determined per the requirements of EN 54-10 is limited to ±25 degrees due to the
nature of the test requirements for the Directional Dependence test. This result is based on indoor
bench top testing using a Bunsen burner as the fire source as opposed to outdoor flame testing that
was used to determine the field of view plots in Section 3.2.1 "Field of View".

The margin of error in the range measurement is esti-
mated at ±5 ft (±1.5 m) due to wind conditions and flame
turbulence.
