From the field

Real photos from a recent Zion ERCES installation in a large-format retail facility in Leander, Texas. Equipment we install and the way we install it — designed to each building's RF environment, AHJ requirements, and operational constraints.

Zion technician commissioning an RSI public-safety BDA — spectrum analyzer running on tablet, RSI cabinet open
RSI ERCES BDA commissioning, Leander TX. RSI M5-Series BDA enclosure open during acceptance testing. Spectrum analyzer running on tablet shows the in-band signal across the local public-safety frequencies. Backup batteries visible at bottom — sized for the 12-hour standby per NFPA 1225 (2022 ed.).
Zion technician working at a fire riser room with RSI BDA enclosure visible — sprinkler piping and gauges in background
BDA installation alongside the fire riser, Leander TX. RSI BDA cabinet co-located with the sprinkler riser — a common installation profile for retail and mid-size commercial. Visible: RSI enclosure with batteries, double-interlock check valve, pressure gauges, and tamper switches. Pathway survival per NFPA 72 / IFC §510.
PCTEL SeeGull IBflex RF survey receiver mounted on a Kishigo high-visibility vest with Zion logo
RF site survey kit, Leander TX. PCTEL SeeGull® IBflex receiver in walking-survey configuration. The SeeGull captures RSSI / DAQ data across the public-safety bands on a calibrated antenna; results map directly to the IFC §510 / NFPA 1225 grid coverage criteria. The grid the AHJ will ask about during acceptance is the one we walk during the pre-design survey.
ERCES DAS donor / service antenna mounted to ceiling truss in a commercial building
DAS antenna on ceiling truss, Leander TX. Public-safety distributed antenna mounted to the building's structural truss with proper standoff and grounding. Pathway and antenna positions selected from the RF survey — not from a generic template.
