Public Safety

In the unlikely event that you are in an emergency situation at your work, school, or local big-box retailer, how do you make sure that help is on the way? Emergency responder radio communications systems (ERRCS) are the primary means for reaching out to first responders when you need help in an emergency.

First responders use special handheld radios that pick up signals from ERRCSs so they can provide assistance quickly and effectively. Once the emergency personnel respond to the incident, the ERRCS (sometimes also called Public Safety DAS) will also facilitate communication between the members of the team, by eliminating “dead zones” where radios and walkie talkies don’t work.

Public Safety DAS for First Responders & EMS

While concrete and metal are strong building materials, they also block out radio signals. Radio frequencies are strong at their source and become weaker the farther they get from the transmitter, so when emergency responders enter your building, their radios may not be strong enough to penetrate the building’s materials.

It is more and more common for first-responders, (Police/Fire/EMS), to demand reliable ubiquitous radio coverage to ensure the safety of the public, as well as their own. In many high-profile cases, poor in-building radio coverage has a negative impact on first responders ability to communicate effectively in a crisis situation, further complicating serious tragedies. The prevailing thought today is that “Mission-critical” coverage can no longer end at the building’s doorway, basement, or stairwell.

What Makes a Public Safety Distributed Antenna System Work In a Crisis

Emergencies happen when you least expect them. Managing a property is a large responsibility, but you can sleep soundly knowing that you’ve invested in the right insurances and assurances. An EERCS (also called public safety DAS) is one of those assurances.

To have a public safety DAS installed in your building, a team of professionals will survey your property and design a system that will provide your building or property with optimum coverage. As with passive DAS designs, professionals install a series of signal repeaters for public safety DAS. But because disaster situations can be highly volatile, local codes for a public safety DAS typically require some or all of the following features above and beyond a cellular DAS:

  • You must have a battery backup for your DAS in case you lose power during an emergency.
  • Your antennas must have NEMA-4 enclosures that are designed to withstand fire and water.
  • The signal of your antennas must meet a minimum requirement.
  • You must perform regular testing on your system to make sure it’s working correctly, and perform needed maintenance.
