Seamless Dispatch Continuity

With the industry-wide discontinuation of legacy 911 dispatch products, Secure Headset Group (SHG) has stepped in to ensure your center never goes silent.

SHG is engineered specifically for Public Safety Answering Points (PSAPs). These are not office headsets modified for dispatch; they are military-grade tools built for 24/7 high-stress communication environments.

100% Signal Compatibility: Guaranteed to work with existing Hirose 6-pin console ports.
Zero-Failure PTT: Tested to millions of cycles for uncompromising reliability.
Dispatcher Safety: Built-in acoustic limiting to protect hearing during loud signal spikes.

The HP Poly Replacement

Don't let the discontinuation of the SHS1890 or HW series disrupt your operations. SHG provides the exact form factor, pin-out, and durability your dispatchers are trained on.

  • Drop-in replacements for Plantronics SHS1890
  • Compatible with EncorePro HW510/520/710/720
  • Works with Motorola, L3Harris, and Zetron Consoles
