Comba’s CriticalPoint 700MHz/800MHz BDAs are designed for use with public safety first responders in mind. Fully compliant with the IFC and NFPA (National Fire Protection Association), CriticalPoint’s BDAs are offered in 0.5W, 2W or 5W of downlink power per band depending on the size of the building that needs to be covered. The features don’t stop there. The unit also includes comprehensive alarming capabilities, which supports all NFPA and IFC required monitoring and alarming, and also provides local and SNMP based remote monitoring. The built-in signal generator and isolation testing function provide great convenience to system integrators during deployments. Finally, the unit can be ordered either AC or 48V DC powered, allowing for flexibility depending on the design of the system. In addition, by utilizing Comba’s well-known high efficiency amplifier design, the BDA provides a very small footprint, light weight design, low electrical operating costs, and low UPS backup costs. Comba’s total vertical in house design and manufacturing capabilities, and supply chain management resources, ensures that the CriticalPoint BDA is a very affordable, reliable and state of the art.
