The SureCall Guardian3™ QR (Quick Response) public safety signal booster amplifies FirstNet signals for first-responder and emergency services radios, providing consistent signal for public safety officials who are counting on reliable communication inside large buildings. The Guardian3 QR’s tri-band booster has a maximum gain of +80 dB on the 700 MHz (FirstNet Ready), 800 MHz, and 900 MHz SMR (Specialized Mobile Radio Service) public safety frequencies.

Building codes require most newly-constructed large buildings, as well as existing large buildings that undergo expansion, to have signal strength of −95 dBm or better in critical areas like elevators and stairwells. The Guardian3 QR provides improved signal for those areas, and meets National Fire Protection Association (NFPA) and International Fire Code (IFC) requirements.

The Guardian3 QR features a NEMA-4 rated amplifier housing to protect against hose-directed water. It also comes equipped with dry contact 7-pin alarming capability and UPS and Ethernet port-enabled remote monitoring.
