The SureCall Guardian4 is a Public Safety Bi-Directional Amplifier for First Responders.
The Guardian4 amplifies FirstNet signals for vital communications. It provides consistent, reliable signal coverage for First Responders and other public safety officials who need two-way radio communication inside large buildings.
The Guardian4 has a maximum gain of 80 dB on the Public Safety frequency bands, supporting 700 MHz (FirstNet Ready) and 800 MHz. This is a slightly narrower frequency range than SureCall’s other Public Safety amplifier, the Guardian3 QR. This narrower range means that the Responder does not bleed into the cellular band, eliminating any risk of co-channel interference.
Most newly constructed large buildings, or existing buildings which have expanded, 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. The SureCall Guardian4 meets the code for NFPA 1221 and IFC 510.
It 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 Guardian4 comes with SureCall’s 3-year warranty. A 5-year warranty is also available.
