The work, on the ground.
A gallery of Zion's installation, inspection, and design work across the fire-protection trades — sprinkler design, clean-agent suppression, backflow, kitchen suppression, alarm panels, and ITM. We're swapping in fresh Zion job-site photos as our team collects them; for now, the gallery walks you through the work by category.
Honest disclosure: photos below are equipment and category illustrations. Real Zion job-site documentation is being added by our field team — we won't pad this page with stock images that aren't ours.
Sprinkler design & layout
NICET III sprinkler-layout work backed by a licensed Professional Engineer on the Zion design bench. Hydraulic calculations, sealed drawings, AHJ-ready submittals.
Clean-agent suppression systems
Inert-gas (IG-541) cylinder banks for data center, telecom, and critical-process protection under NFPA 2001. NICET III Special Hazards design and commissioning.
Backflow prevention assemblies
Double-check and reduced-pressure assemblies tested and certified by Zion's licensed Backflow Prevention Assembly Testers. Annual TCEQ-compliant testing across Texas.
Sprinkler riser inspection & ITM
NFPA 25 inspection, testing, and maintenance on commercial sprinkler risers. Five-year internal-pipe inspections, quarterly main-drain testing, annual valve inspection.
Kitchen suppression — UL 300
Type-I hood wet-chemical suppression systems for restaurants and commercial kitchens. NFPA 96 compliant, semi-annual inspection, AHJ-coordinated cylinder service.
Fire extinguisher inspection & service
NFPA 10 annual inspection, six-year teardown, and twelve-year hydrostatic service. Walk-in service available at our McKinney HQ — the service we're best known for.
Emergency & exit lighting
Monthly 30-second function tests and annual 90-minute discharge tests under NFPA 101. Bulb replacement, battery service, and AHJ-compliant deficiency reporting.
Want a project written up here?
If we've done work on your building you'd be willing to let us showcase — sprinkler retrofit, clean-agent install, an ERCES commission, a difficult AHJ negotiation — we'd love to write it up properly. Short interview, photo permission, draft for your review before anything publishes. Nothing goes live without your sign-off.

- Before-and-after photos on retrofit and major repair work, with the system tag visible and the AHJ inspector's name on the closed permit.
- NFPA code citations in the project summary — every design decision tied to a referenced edition and section.
- Owner sign-off on every word and every photo before anything is published. We don't surprise customers with their building on our website.
- No stock photography. Equipment-category placeholders during the build phase get replaced with real Zion field photos. We label them honestly until they're swapped.
