Annual load bank testing, fire pump inspection, ATS maintenance, and generator fuel service — ensuring your backup power systems keep fire alarms, sprinklers, and emergency lighting operational during outages.
Delta Fire Equipment maintains and services emergency generators and fire pumps that power your building's fire and life safety systems during utility outages. Fire alarm panels, emergency lighting, fire pumps, stairwell pressurization, and smoke control systems all depend on reliable backup power.
We provide annual testing, load bank services, fuel system maintenance, and transfer switch inspections to keep these critical systems code-compliant and operational — with the fire code focus that sets Delta apart from general generator contractors.
Fire alarm systems require a minimum 24-hour battery backup plus standby power. Fire pumps must start automatically and maintain pressure. Emergency egress lighting must illuminate within 10 seconds. All of this depends on a properly maintained generator and transfer switch.
Backup power for fire and life safety involves multiple systems working together. Delta services them all — from the generator itself to the transfer switch, fire pump, and battery systems.
Diesel and natural gas generators provide backup power for all emergency loads — fire alarms, sprinkler systems, emergency lighting, elevators, and smoke control. NFPA 110 requires annual load bank testing at 100% rated load to verify capacity and identify fuel system or cooling problems.
Fire pumps maintain water pressure in sprinkler and standpipe systems when municipal supply pressure is insufficient for high-rise or large buildings. NFPA 25 requires annual flow testing, weekly churn tests, and regular inspection of the pump, driver, and controller to verify reliable operation.
Automatic transfer switches detect utility power loss and transfer emergency loads to generator power within 10 seconds. ATS failures are a leading cause of emergency power system failures — regular testing and maintenance ensures reliable transfer when it matters most.
Uninterruptible power supply systems provide immediate power bridging while generators start — critical for fire alarm panels, which require no power interruption to avoid false alarms. We test battery capacity and condition to ensure these systems perform during extended outages.
From annual load bank testing to fire pump flow tests and fuel system maintenance, Delta handles every aspect of emergency power for fire and life safety systems — with complete documentation for compliance records.
Annual load bank testing at 100% rated load per NFPA 110. We verify generator output, identify voltage and frequency stability issues, and confirm the system can sustain your fire and life safety loads for the required duration.
Annual fire pump flow testing verifies pump performance at churn, rated, and peak flow. We inspect the pump, driver, controller, and piping per NFPA 25, and provide a certified test report for fire marshal review.
We test ATS transfer time, voltage sensing, and mechanical operation — then inspect contacts, connections, and control wiring for signs of wear, overheating, or corrosion that could cause failure during an actual outage.
Diesel fuel degrades over time and can cause generator failure at the worst possible moment. We provide fuel polishing, tank inspection, fuel treatment, and day tank maintenance to keep your fuel system clean and reliable.
Fire pump controllers are the brain of the fire pump system — they must automatically start the pump on pressure drop, run through power failure conditions, and provide accurate status to fire alarm panels. We inspect and test controller operation annually.
NFPA 110 requires generators to be exercised weekly under load. We manage your exercise program — scheduling runs, monitoring performance, logging results, and alerting you to any issues identified during routine exercises before they become failures.
Multiple codes govern emergency generators and fire pumps for California commercial buildings. Delta ensures compliance with all of them — one service provider, complete documentation.
Governs the installation, testing, and maintenance of emergency and standby power systems. Requires annual load bank testing at 100% rated load for systems that don't achieve 30% loading in normal operation.
Requires annual fire pump flow testing, weekly churn tests, and regular inspection of pumps, drivers, and controllers. Non-compliance can result in sprinkler system deficiency citations.
Requires fire alarm systems to have 24-hour standby power capability. Generator and UPS systems powering fire alarm panels must be tested annually to verify adequate capacity and transfer speed.
Adopts NFPA standards and adds California-specific requirements. Fire marshals routinely verify generator and fire pump testing records during occupancy inspections — missing documentation can trigger citations.
Any California commercial building with emergency generators or fire pumps must maintain and test them per code. This includes:
Fire code-focused generator service.
Unlike general generator contractors, Delta understands which loads are fire and life safety critical. We test your generator specifically for the fire alarm, sprinkler, and emergency lighting loads it must support — and bundle generator testing with your other annual fire safety inspections for maximum efficiency.
