Public Safety Band Signal Booster

TowerIQ’s TQ-GUARDIAN-A Public Safety Band signal booster enhances in-building 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.

TQ-GUARDIAN-A 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.

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. TQGUARDIAN-A meets the code for NFPA 72/1221, IFC 510, and features UL2524 Certification including UL 50 certified/NEMA-4 rated amplifier housing.

Additionally, the TQ-GUARDIAN-A comes equipped with dry contact 9-pin alarming compatibility, UPS and Ethernet port enabled remote monitoring. TowerIQ provides an industry leading 3-year warranty.
