Built to perform in any environment

Zephyr™ PSM Responder offers visibility into the physical status of personnel deployed in the most challenging environments. Deployed over existing digital radio equipment, PSM Responder offers a low hassle, cost effective way to help improve the safety of you team, and to help optimize mission outcomes.

We at Zephyr have learned through years of experience that the key to successful training is Physiological Status Monitoring (PSM) – and with Zephyr’s PSM Responder ECHO system, you can see physiological intensity and load (cumulative effort) in real-time.

All the data you need to keep your people safe

PSM Responder ECHO tracks up to 50 subjects at the same time. PSM Responder ECHO tracks up to 50 subjects at the same time.

Designed for squads of people deployed in the harshest environments, Zephyr™ PSM Responder enables the monitoring of multiple individuals and teams simultaneously. Zephyr™ PSM Responder is for Fire Fighter teams, HAZMAT, WMD CST, or any teams that deploy into potentially hazardous, challenging environments.

Knowing the real-time physical status of personnel can assist Incident Commanders and Safety Officers in their decision making at the fireground. PSM Responder deploys over existing voice radio systems, thus increasing a firefighter’s situational awareness, while minimizing weight, hassle and the cost of deployment.

The Smart Fabric strap can be worn as a chest strap, or as a fully integrated shirt. Being fabric based, the BioHarness™ strap does not impact the wearer’s ability to perform their duties and does not result in skin irritation over time.

PSM Responder ECHO Advantage

PSM Responder ECHO gives commanders a look “inside” their team members. Configurable thresholds and real-time monitoring allows management of training intensity for each person – while allowing you to monitor 50+ people simultaneously.

Streaming live data allows real-time insight into the potential of heat stress, fatigue and dehydration. The system allows you to design practice drills and exercise regimes that will train each responder, and the unit as a whole, to their peaks, ensuring the highest level of performance per unit of effort.

PSM Responder ECHO generates customizable, detailed reports and analysis of individual and team progress – including trend analysis of individuals over multiple sessions or sub sessions. Comparisons between individuals can be created quickly and easily. Share reports with other units and use them to fine tune practice drills and exercise regimes to achieve individual and team goals.

PSM Responder ECHO also includes fitness testing utilities that help to determine the fitness level of anyone you are monitoring.

You no longer have to worry about guessing how your people are performing. With Zephyr’s PSM Responder ECHO, you really can Measure Life…Anywhere!
