The Guardian3 allows newly constructed buildings with an area of at least 10,000 square feet per floor, and at least three floors high, meet the required signal strength of -95 dBm or better in designated critical areas—elevators, stairwells, etc.
Cellular signal booster manufacturer, SureCall, just announced its latest signal amplifier, the Guardian3 Quick Response (QR). The amplifier is designed to enhance all public safety frequencies, improving the quality of first responder communications, especially in commercial buildings with weak signal strength.
“New construction in public buildings like offices, hotels, and hospitals are being made more energy efficient, however this also degrades cellular signals,” said Hongtao Zhan, CEO of SureCall. “Our new Guardian3 QR provides compliance, safety, and peace of mind for building owners, ensuring that emergency responders are able to communicate in the most critical moments.”
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.—to receive a certificate of occupancy. The Guardian3 QR has a max gain of 80 dB on the public safety bands, and output power up to 26 dBm. It improves coverage up to 80,000 sq. ft. for all public safety bands including 700 MHz (FirstNet Ready), 800 MHz, and 900 MHz SMR and can support more than 100 simultaneous users per band.
The Guardian3 QR also 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 7-pin alarming capability, UPS and Ethernet port enabled remote monitoring.
SureCall’s Guardian3 QR is now available for $6,669.
