ERRCS versus Cellular DAS

An Emergency Response Radio Communications Systems (ERRCS) and a Cellular Distributed Antenna Systems (DAS) are essentially the flip side of the same coin, – with a few exceptions. An ERRCS is typically a mandated code requirement; a Cellular DAS is an “amenity”, although these days many schools, hospitals and other facilities understand that the need for users to make 911 calls over cellular is just as important as First Responder radios working in the building when they show up.

First responders rely on the ability to communicate through their radio systems, but they also rely on the data, location, and other sources of information during an emergency. This information is critical to an effective response to a 911 call in a building – whether it’s a Police, Fire or EMT emergency, seconds can matter.

Who Uses ERRCS Systems?

ERRCS systems are used by first responders and emergency services such as fire, medical, homeland security, disaster response agencies, and police officers to facilitate in-building radio communication during an emergency.

What Are Some Factors Involved In Determine If An ERRCS Is Need?

Every jurisdiction with an ERRCS requirement conforms to one or more national, state and local codes. These codes drive the design and installation of the ERRCS. Many states now require an ERRCS for any newly constructed building over a certain size. A radio coverage test when the building is substantially complete will determine the necessity for an ERRCS.
