Ensuring public safety through a bi-directional amplifier

Are you in the construction industry? For the public safety, the National Fire Protection Association and the International Fire Code have adopted IFC 510 and NFPA 72 code to ensure two-way radio signal for first responders can be reached in all areas of a building in the event of an emergency.

Unfortunately, many public buildings have gaps in their wireless communications, especially in hard to reach areas such as basements, parking garages, stairwells and elevators. These spaces often impede two-way radio signal, causing risk to both lives and the rescue operation.

NFPA 72 and IFC 510 require a minimum radio strength in all buildings for public safety radio services. Otec Communication Systems’ comprehensive site survey report will revea whether the building’s signal capacity meets the regulatory code requirements during a fire inspection. If needed, Otec is equipped to install a Bi-Directional Amplifier to ensure minimum radio signal requirements are met.
