The training covers the following references:

• NFPA 70: National Electrical Code, 2014 Edition
• International Building Code, 2015
• NFPA 72 National Fire Alarm and Signaling Code, 2016

Each reference serves a different purpose. The National Electrical Code covers electrical installation requirements, wiring methods, conductors, cables, boxes, raceways, grounding, bonding, power supplies, and power-limited fire alarm circuits. The International Building Code addresses the building conditions and occupancy requirements that determine when alarm, detection, notification, and emergency communication systems are required. NFPA 72 provides detailed requirements for fire alarm and signaling system components, performance, installation, inspection, testing, and maintenance.

Because this is a seminar-style training program that covers fire alarm systems, fire detection equipment, emergency voice communication systems, signaling circuits, initiating devices, notification appliances, power supplies, control wiring, building-code requirements, and National Electrical Code provisions, you only need to attend the sessions covering the books included on your specific exam.

Exam Details

The City and County of Denver requires ICC Exam #380, Journeyman Electrical Signal Operator, for applicants pursuing the Electrical Signal Journeyman certificate. The exam identifier may appear as 380_CO_D in the ICC examination system.

The examination evaluates knowledge associated with installing and repairing electrical wiring and equipment for fire alarm systems, fire detection systems, emergency voice communication systems, burglar alarms, and electrical signaling and control wiring.

Candidates should be prepared to move between three different code books. The correct reference depends on the subject of the question. Building occupancy and alarm-system requirements may direct you to the International Building Code. Electrical wiring, conductor, cable, grounding, or power-limited circuit questions may direct you to the National Electrical Code. Questions involving system operation, initiating devices, notification appliances, alarm signals, supervision, testing, and maintenance may direct you to NFPA 72.

Important study areas include:

• Fire alarm system fundamentals
• Electrical signaling and control wiring
• Power-limited fire alarm circuits
• Fire alarm control units and power supplies
• Initiating devices and initiating device circuits
• Notification appliances and notification appliance circuits
• Alarm, supervisory, and trouble signals
• Emergency voice communication systems
• Building occupancy and alarm requirements
• Wiring methods and cable installation
• Grounding and bonding
• Boxes, raceways, supports, and protection
• System documentation and acceptance
• Inspection, testing, and maintenance

Efficient reference navigation is an important part of preparation. Candidates should practice identifying the subject first and then selecting the book most likely to contain the answer. This method is more efficient than searching every reference for each question.

Open Book Test

The ICC Journeyman Electrical Signal Operator examination uses approved code references during testing. Candidates should prepare the exact editions assigned to the exam and follow the current ICC rules governing books, notes, tabs, and other materials.

The approved reference set for this training includes NFPA 70: National Electrical Code, 2014 Edition; International Building Code, 2015; and NFPA 72 National Fire Alarm and Signaling Code, 2016.

Having the books available does not eliminate the need for preparation. Candidates need to understand how the references are organized and which book applies to each subject. Learning the table of contents, index, definitions, chapter structure, NEC article structure, and NFPA 72 system organization can reduce search time.

Books should be prepared before the examination in accordance with current ICC reference-material policies. Reference materials may be inspected before testing. Unauthorized loose papers, separate study notes, or materials outside the permitted rules should not be taken into the testing area.

Permanent tabs can help identify major subjects, but the books should remain easy to navigate. Useful tab categories may include fire alarm systems, power-limited circuits, wiring methods, grounding, initiating devices, notification appliances, emergency communications, inspection, testing, and building alarm requirements.

Candidates should not rely only on tabs. A question may use terminology that differs from the tab label. Practice using indexes, definitions, chapter headings, cross-references, and tables so you can locate material through more than one method.

Licensing Steps

1. Review the certificate scope. Confirm that the Denver Electrical Signal Journeyman certificate matches the fire alarm, detection, emergency communication, burglar alarm, signaling, and control wiring work you intend to perform.
2. Document qualifying experience. Gather records showing at least two years as an apprentice or trainee under a licensed electrical contractor or electrical signal contractor.
3. Prepare notarized experience letters. Each letter should describe what work you performed, when you performed it, and where each project was located.
