Product SRVA

The SRVA is designed for:

  • Mass Decontamination
  • CBRNE Incidents
  • HazMat
  • Technical Rescue
  • High Noise Environments
  • Tactical Response
  • Face Masks, Level A, B, C Suits

The SRVA combines the functionality of the SR65M push-to-talk radio accessory and the CSVA voice amplifier to provide push-to-talk and voice amplification all in one unit.  Ideal for HazMat, Mass Decontamination, CBRNE and drug lab takedowns, this radio accessory is worn on the outside of a Level A, B or C suit. 

 The amplification allows responders to speak at normal levels and be heard. The throat mic clearly transmits the user’s voice despite ambient noise from breathing apparatus. The large push-to-talk switch provides users with quick and easy access to their radio network despite cumbersome clothing, like gloves.

The throat mic, worn underneath the facemask and/or protective suits, transmits the user’s voice in low to high noise environments. 

The SRVA comes with a variety of hearing options depending on the responder’s preference.  A Quick Connect cable allows for rapid attachment and detachment from the unit.
*A Radio Interface Cable must be ordered with the SRVA
