CHAPTER 1: INTRODUCTION & OVERVIEW
1.1 Product Overview
GuardianA is a Class B, 2-watt, bi-directional amplifier with a maximum gain of 90 dB supporting both the 700 and 800 MHz Public
Safety frequency bands.
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 – Emergency Command Centers,
Fire Pump Rooms, stairwells, standpipe, cabinets, 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 integrated alarming compatibility, UPS and Ethernet enabled remote monitoring.
