BDA Systems

Will first responders be able to communicate successfully and effectively throughout your building during a fire emergency? Unfortunately, many commercial buildings are facing poor in-building radio signal coverage and dead spots due to the building’s type of construction materials. This has become such a serious problem, the requirement of properly installed and maintained Emergency Responder Communication Enhancement Systems (ERCES) has been written into building code standards. Kistler O’Brien Fire Protection is the life safety partner that can help.

Reliable radio coverage is not a luxury. It’s a necessity.

Kistler O’Brien Fire Protection is now quoting reliable Emergency Responder Communications Enhancement Systems (ERCES), commonly referred to as BDA and DAS Systems. BDA is a Bi-Directional Amplifier system that is linked to a Distributed Antenna System (DAS). Together these are required to ensure first responder radios work properly in new and existing buildings that would experience poor coverage without it. BDA Systems are the code-compliant, UL Listed technology of choice for ERCES.
