What Makes A Good Public Safety Radio System?

A DAS radio system or a distributed antenna system is crucial for public safety. These installations allow police officers, the fire department, and other first responders to maintain communication using their radio system despite being inside a building. With a proper communication system in place, first responders do not have to enter a situation blind and devoid of important information.

Since it is relatively clear that a public safety radio system is a must, how can civilians, most especially building owners create an effective DAS radio system? These are some important details to remember when setting up a distributed antenna system:

Meets The Minimum System Coverage

When designing the system, it is in everyone’s best interest to pay close attention to the minimum system coverage requirement that is set in place by first responders. For example, when it comes to the fire department the National Fire Protection Association or the NFPA requires 99% system coverage in areas that are considered vital within a building. This usually means areas that see the most foot traffic such as the lobby, the pantry, and the office floors.

As for the International Fire Code, the IFC their standard only requires at least a 90% system coverage. Since it is the safety of human lives that are at stake, it is best to request for a design that meets the NFPA minimum because it is always better to be safe and sorry.

Coverage For Hard To Reach Areas

During an emergency, areas with the highest foot traffic aren’t the main concern. First responders are also tasked with searching hard to reach areas such as the basement, storage areas, and stairwells. Building owners should also consider amplifying the radio signals in these areas to ensure that communication is not affected when searching within these areas.

Invest In A Bi-Directional Amplifier

A BDA or a bi-directional amplifier is a device that helps ensure communication is not lost between either party. The BDA is capable of amplifying both the receiving and transmitting modes. Adding a signal amplifier along with the distributed antenna system within a building allows for better communication during a crisis.

It is worth every penny to ensure that everyone, meaning the tenants and first responder’s safety is enhanced.

Waterproofing The System

During emergency cases such as a fire, water will be used to control it. Since the pressure and amount of water from the fire hydrant are very strong, there is a good chance that it will reach the BDA and DAS systems which will impact their ability to function.

Encasing the antenna inside a waterproof container ensure they are not affected by water and will continue to function until the crisis is contained. A waterproof casing is also another way to protect the investment from weathering and damage over the years.

Public Safety Is A Priority

All buildings should be equipped with radio system amplifiers for everyone’s sake and safety. First responders rely on communication to coordinate with each other to save lives. As long as radio signals at both transmitting and receiving end are active and functioning, the general public’s safety will not be compromised.
