Fire Alarm Companies Near Me in Ontario, CA
Fireside Security is a licensed C-10 fire alarm, UL-Listed monitoring, access control, and video contractor local to Ontario and San Bernardino County. Dispatched from our Santa Fe Springs operations center.
Fireside Security serves Ontario from our Santa Fe Springs office, delivering engineered commercial fire alarm, UL-Listed monitoring, access control, and video surveillance under a single C-10 license. Ontario's airport, convention center, and surrounding logistics parks give it one of the highest concentrations of high-pile storage in California.
Ontario Fire Department sets the local plan-review and inspection cadence, and our project managers work with it directly — stamped submittals, coordinated shop drawings, and acceptance tests that pass on the first walk. Every ONT-adjacent distribution project needs ESFR alarm integration, monitored fire pumps, and clean smoke-control commissioning — that's our lane.
Every Ontario project is monitored from our UL-Listed central station with LTE-M cellular paths, so your life-safety signaling doesn't depend on the copper POTS lines being retired in 2026.
Most Ontario projects start with commercial fire alarm installation and typically fold in fire alarm inspection & testing, 24/7 ul listed fire alarm monitoring, and commercial video surveillance & cctv for San Bernardino County properties.

Is your Ontario fire alarm monitoring UL-Listed?

How fast can you get to a Ontario property for a site walk?

Do you pull fire alarm permits with the Ontario AHJ?
Yes. We prepare the plan-review submittal, coordinate with the Ontario fire authority and building department having jurisdiction, and attend the acceptance test so the system is signed off and inspection-ready.
Can you combine access control and video surveillance with fire alarm in Ontario?
Yes. Under one contract we install access control and video alongside fire alarm for Ontario and San Bernardino County properties — Fireside holds an alarm company operator license (ACO #7133) in addition to the C-10.
Are you replacing POTS phone lines for Ontario fire alarm and elevator dialers?
Yes. Copper POTS lines are being retired, and we migrate Ontario fire alarm communicators, elevator phones, and gate entry systems to cellular or IP alarm transmission that meets NFPA 72 supervision requirements.
