Fire Alarm Maintenance
Frequently Asked Questions

NFPA 72 and California Fire Code require annual inspection and testing of commercial fire alarm systems, with additional semi-annual or quarterly checks on specific devices such as waterflow switches, duct detectors, and off-premises communications. Altora schedules inspections on a recurring calendar so nothing is missed and reports are ready for the AHJ.

A full NFPA 72 inspection covers the fire alarm control panel, batteries and power supplies, initiating devices (smoke, heat, pull stations, waterflow, tamper), notification appliances (horns, strobes, speakers), off-premises signal transmission to the monitoring center, and any interfaces to elevator recall, HVAC shutdown, or door hold-open devices. You receive a written report with any deficiencies documented.

Commercial smoke detectors are generally replaced every 10 years per manufacturer and NFPA 72 guidance, and sealed lead-acid backup batteries in the fire alarm panel are typically replaced every 3–5 years. Altora tracks device age and battery date codes as part of your maintenance record so replacements are planned, not reactive.

Trouble signals usually indicate low battery, a ground fault, an open or shorted device loop, a communicator failure, or a supervisory condition on a sprinkler or suppression system. Altora technicians diagnose the trouble at the panel, clear the cause, and confirm the system returns to normal — and our monitoring center logs the event for your compliance record.

Yes. We regularly assume maintenance on existing DMP, Notifier, Silent Knight, Bosch, and other commercial fire alarm systems. We perform a baseline inspection, document existing deficiencies, and put the system on a recurring NFPA 72 inspection and service program — no forced rip-and-replace.

Altora issues a written deficiency report with each item categorized (critical, non-critical, or impairment) and a proposed repair scope. Critical items are addressed immediately, and we coordinate any required AHJ notifications, fire watch, or re-inspection so your certificate of occupancy and insurance coverage stay intact.

A well-maintained commercial fire alarm system typically lasts 8–10 years, though individual devices such as smoke detectors and power supplies may need replacement sooner. Altora tracks equipment age during every inspection and provides a replacement roadmap before reliability or compliance is compromised.

False alarms are usually caused by dust in detectors, improper detector placement near HVAC vents or kitchens, outdated sensitivity settings, or unreported construction activity. Altora cleans and tests detectors, verifies placement against NFPA 72, adjusts sensitivity, and trains staff on proper use to reduce nuisance alarms and avoid municipal fines.

Conventional systems group devices into zones, so a trouble or alarm shows the general area but not the exact device. Addressable systems assign every detector and module a unique ID, pinpointing the exact device and location at the panel and monitoring center. Addressable systems are easier to troubleshoot and maintain, and Altora services both types.

California and NFPA 72 require you to keep inspection and testing reports, deficiency correction records, monitoring account records, and as-built system drawings. Altora provides organized digital records after every inspection and service visit so you are prepared for AHJ, insurance, and fire marshal audits.

A maintenance contract is not legally required, but it is the most reliable way to stay ahead of NFPA 72 inspections, avoid missed battery replacements, and ensure fast response when trouble signals appear. Altora contracts include scheduled inspections, priority service, and digital compliance records.

California requires fire alarm service to be performed by a licensed low-voltage contractor and, in many jurisdictions, by a certified fire alarm technician. Self-service can void warranties, violate insurance requirements, and create liability exposure. Altora's licensed technicians handle service, testing, and AHJ documentation properly.
