GuardianA is a Class A, 2-Watt, bi-directional amplifier with a maximum gain of 90 dB supporting both the 700 and 800 MHz Public Safety frequency bands.
SureCall’s GuardianA Public Safety Band signal booster enhances inbuilding coverage for crucial communications, delivering consistent signal for First Responders and other public safety officials who rely on two-way radio communication inside large buildings.
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.
GuardianA meets the code for NFPA 72/1221 and IFC 510 and features a NEMA-4 rated amplifier housing. Additionally, the GuardianA comes equipped with dry contact 12-pin alarming compatibility, UPS port for battery backup and Ethernet port enabled remote monitoring. SureCall provides an industry leading 3-year warranty– extendable to 5 years.
