The Frequency of the illuminated Beacon unit,Red colour with 10 Joule “flash” discharge tube XVBL8B4 with 24VDC supply will depend on the temperature.

At 25°C and 55°C,below are the Frequencies Tolerance Ranges:

At 25°C    0.67Hertz< F < 2Hertz<==> 0.5seconds < T < 1.5seconds

At 55°C    0.5Hertz < F < 1.25Hertz <==> 0.8seconds < T < 2seconds

T- Time Period.

F-Frequency.
