SCBA air cylinder testing and life span
Hydrostatic Test when new
retested every 5 years.
15-30 year life span.
(tested at 7500 psi)
First stage regulator pressure
115psi
When does the relief valve activate to protect the system?
when intermediate pressure exceeds 200 to 225 psi
At what pressure does the warbling whistle activate

HUD Light Progression
Full- 4 green lights
¾- 3 Green lights
½- Green Light flashes for 20 seconds then both solid green
1/3- Light flashes red at rate of 500 milliseconds
10%- 1/3 light flashes at rate of 100 milliseconds
PASS alert timing
approximately 20 seconds. The LED lights will alternate flashing green and red. The alarm will increase in volume approximately every 4 seconds until full alert at 30 to 35 seconds. In full alert, the LED lights flash red and the alarm tones alternate between the front and rear mounted speakers.
