When does the Vibralert alarm activate?

When does the Vibralert alarm activate?

• A. When the second stage reduces to below 50 psi
• B. When cylinder reaches 25% or the first stage fails
• C. Only when the user presses a button
• D. At the end of cylinder life

Answer: (B)

The Vibralert is an automatic warning feature that gives you a tactile cue when your air supply needs attention. It activates in two safe-fail scenarios: when the cylinder pressure drops to about 25% of its full capacity, providing early warning to start exiting or switch to a fresh supply, and when the first stage fails to deliver air, signaling a malfunction in the system regardless of remaining air. It does this without any action from you, so you don’t have to press a button. It is not intended to wait until the cylinder is completely empty, and it doesn’t trigger merely because you’ve reached a low psi on the second stage.
