About the repeater:
Overview:

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 100+ simultaneous users per band on 700 MHz (FirstNet Ready), 800 MHz, and 900 MHz SMR (Specialized Mobile Radio Service).

In the majority of cases, newly constructed buildings with an area of at least 10,000 square feet per floor, and at least three floors high 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 Chapter 24 Emergency Communications System of NFPA72 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.
