The SureCall Guardian4™ public safety signal booster amplifies FirstNet signals for first-responder and emergency services radios, providing consistent signal for public safety officials who are counting on reliable communication inside large buildings. The Guardian4’s tri-band booster has a maximum gain of +80 dB on the 700 MHz (FirstNet Ready) and 800 MHz public safety frequencies.
Building codes require most newly-constructed large buildings, as well as existing large buildings that undergo expansion, to have signal strength of −95 dBm or better in critical areas like elevators and stairwells. The Guardian4 provides improved signal for those areas, and it meets National Fire Protection Association (NFPA) and International Fire Code (IFC) requirements.
The Guardian4 features a NEMA-4 rated amplifier housing to protect against hose-directed water. It also comes equipped with dry contact 7-pin alarming capability and UPS and Ethernet port-enabled remote monitoring.
Public safety systems require fire-rated cable in plenum spaces. Plenum cable fully meets state and federal building codes.
Powerful Signal recommends ½-inch plenum air coax. Half-inch cable has nearly half the signal loss per foot of cable compared to 400-type coax cable, delivering stronger signal from the SureCall amplifier to emergency responders’ communications devices.
(Plenum air cable is available at additional cost. Call Powerful Signal at 866-912-3444 for details.)
