What Class Code 7605 Covers
This code covers on‑site installation, testing, maintenance and repair of security and fire alarm systems, including intrusion sensors, smoke/heat detectors, pull stations, strobes, annunciators, alarm control panels, communicators and associated low‑voltage wiring and conduits. Work includes mounting devices, routing and terminating cable in ceilings, attics and walls, programming panels and networked communicators, troubleshooting system faults and coordinating final acceptance with authorities having jurisdiction. It applies to both new system installs and retrofit/service work, whether performed in residential, commercial, industrial or institutional settings. Activities such as system commissioning, periodic inspection, component replacement and emergency service calls are included under class 7605.

Common Injury Risks
Understanding the $2.678 Rate
The approved pure premium rate of $2.678 per $100 of payroll represents the estimated cost of future losses for workers classified in 7605, expressed per $100 of payroll. To calculate pure premium, divide total payroll by 100 and multiply by 2.678 (for example, $100,000 payroll yields $2,678 pure premium); insurers then add expense loads, state assessments, and any discounts or credits to produce the final premium. Your actual cost is affected by experience modification, accuracy of payroll classification, safety programs, claims history and underwriting adjustments.
Cal/OSHA Compliance Requirements
California employers must maintain an effective Injury and Illness Prevention Program (IIPP) and provide task‑specific training for ladder use, electrical safety and confined‑space awareness. Relevant Cal/OSHA standards include ladder and fall protection rules, Electrical Safety Orders, control of hazardous energy (lockout/tagout) where applicable, and heat illness prevention for outdoor work. Keep thorough training records, equipment inspections and corrective action logs to meet Cal/OSHA expectations and simplify inspections.
How Key HR Helps Employers Under Class Code 7605

Get a QuoteFrequently Asked Questions
Are mobile technicians who travel between jobs classified under 7605 while driving?
Yes — technicians whose primary duty is installation or repair of alarms remain in class 7605; travel time to and from job sites is payroll and should be reported. If an employee’s primary duties are sales or installation is incidental, employers must document time splits and consult the carrier or PEO to confirm correct classification.
Do fire alarm installers need special licenses or permits in California?
Many jurisdictions and general contractors require installation by a qualified technician. Low‑voltage system contractors typically operate under a C‑7 (Low Voltage) license; some fire‑related wiring may require a C‑10 (electrical) license or coordination with a licensed electrician. Local fire authority acceptance and permit inspections are common for fire alarm work.
What practical steps reduce workers' comp costs for alarm installers?
Implement a written IIPP, provide ladder and aerial lift training, require PPE and electrical safety practices, enforce job hazard analyses for attic/ceiling work, maintain prompt injury reporting and light‑duty return‑to‑work options, and keep accurate payroll/classification records. A PEO can help deploy these measures consistently and document safety performance for better underwriting.
