About This Product – SureCall Guardian4™ Bi-Directional Amplifier
Public Safety BDA for First Responders
SureCall Guardian4™ Bi-Directional Amplifier for 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.
The Guardian4 is a bi-directional amplifier with a maximum gain of 80 dB on the Public Safety frequency bands, supporting 700 MHz (FirstNet Ready) and 800 MHz.
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. Guardian4 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 Guardian4 comes equipped with dry contact 7-pin alarming capability, UPS and Ethernet port enabled remote monitoring. The BDA features sturdy metal construction and is covered by an industry leading 3-year warranty.
