SureCall's Guardian3™ QR Public Safety Band signal booster amplifies FirstNet signals for crucial communications, delivering consistent signal for First Responders and other public safety officials relying on two-way radio communication inside large buildings.
Guardian3 QR (Quick Response Unit) is equipped with a tri-band booster that has a maximum gain of 80 dB on the Public Safety frequency bands, supporting 700 MHz (FirstNet Ready), 800 MHz, and 900 MHz SMR (Specialized Mobile Radio Service).
In the majority of cases, newly constructed buildings with considerable size, or existing buildings that increase capacity by expanding the building footprint are required to have signal strength of -95 dBm or better in designated critical areas – elevators, stairwells, etc. – in order to receive a certificate of occupancy. Guardian3 QR meets the code for NFPA 1221 and IFC 510 and features a NEMA-4 rated amplifier housing, which eliminates the need for an additional NEMA enclosure.
Additionally, the Guardian3 QR comes equipped with dry contact 7-pin alarming capability, UPS and Ethernet port enabled remote monitoring. The Guardian3 QR amplifier features sturdy metal construction and is covered by an industry leading 3-year warranty.
