Master Alarm Installation

New or replacement master alarm panels at the engineer / security station, wired back to every gas source with proper supervised circuits per NFPA 99 5.1.9.

Area Alarm Installation

Smoke-zone area alarms for ORs, ICUs, post-op, and patient floors — fully labeled, supervised, and tested before commissioning.

Retrofit & Troubleshooting

Replace failing legacy panels, chase nuisance alarms back to the sensor, repair broken supervised loops, and document the fix for your AHJ.

Alarms That Actually Get Trusted

Most med-gas alarm complaints come down to flaky sensors, missing supervised loops, or unlabeled panels. We install and retrofit to NFPA 99 5.1.9 so every signal is trusted.

Frequently Asked Questions

Medical gas low-voltage wiring is the supervised cabling, sensors, relays, and alarm panels that monitor every medical gas and vacuum source in a facility. It's the system that tells your engineering and clinical staff the moment a pressure goes out of range or a source switches over.

NFPA 99 5.1.9 requires a master alarm at two locations — typically the engineering / maintenance office and a 24/7 staffed area such as security or the switchboard — for every Level 1 medical gas system. Each master alarm must be supervised and labeled for every gas it monitors.

Area alarms monitor pressure inside a specific smoke compartment or care area (OR suite, ICU, NICU, etc.). Master alarms monitor the source equipment for the whole facility. Both are required by NFPA 99 and both must be supervised, audible, and visual.

Yes. We regularly replace legacy alarm panels — Ohio Medical, older Beacon Medaes, Tri-Tech — with modern Amico, Beacon, or Powerex equivalents. We reuse existing supervised cabling where possible, terminate properly, and re-commission the entire loop.

Yes. Nuisance alarms are almost always a failing sensor, a broken supervised loop, a corroded terminal, or a panel programming error. We start with a topology audit, then methodically test each loop and sensor until we find and document the root cause.

Yes. Our ASSE 6030 verifiers handle the post-install verification so the new or modified alarm system is signed off and AHJ-ready in one trip.
