IA Fire Alarm cheat sheet
IA Fire Alarm · Keep the key ideas within reach.
Alarms & Fire Safety
A fire alarm system is classified by its signaling type: conventional (zones share a circuit) versus addressable (each device reports a unique identifier to the control panel).
NFPA 72 defines four initiating device circuits (Class A/B) and notification appliance circuit classes; Class A circuits continue to operate through a single open or ground fault, Class B circuits do not.
Detector spacing on a smooth ceiling is generally 30 ft for smoke detectors under NFPA 72, with the first detector within 15 ft of any wall; higher ceilings widen spacing per the applicable table.
Smoke detector spacing must be reduced where ceiling height, beams, or joists create compartments; beams deeper than 18 in. typically require detectors in each bay.
A manual pull station must be mounted 42-48 in. above the finished floor to the operable handle and within 5 ft of the exit door on the latch side.
Notification appliance circuits (NACs) must provide a sound level at least 15 dBA above ambient and at least 75 dBA at the pillow in sleeping areas; audible appliances must be synchronized when installed in the same area.
Initiating devices and NACs require separation from other systems; surge protection and dedicated circuit disconnecting means are required at the panel per NFPA 72 and NFPA 70 Article 760.
Fire alarm cable classes: FPL (power-limited fire protective signaling) and FPLR (riser-rated) and FPLP (plenum-rated); plenum cable is required in environmental air spaces.
Supervising station types include central station, proprietary, remote supervising, and auxiliary; each has distinct retransmission and recordkeeping requirements under NFPA 72.
Iowa Code Chapter 103 - Electricians and Electrical Contractors
Iowa Code Chapter 103 establishes statewide licensing for electricians and electrical contractors, administered by the Iowa Electrical Examining Board within the Division of Labor.
License classes include master electrician, journeyman electrician, apprentice, and electrical contractor; each class has separate qualification and supervision rules.
An electrical contractor license is held by a business entity and must have a licensed master electrician designated as the responsible managing employee.
Apprentices must be registered and work under the direct supervision of a licensed journeyman or master electrician; hour ratios and supervision limits are set by board rule.
Chapter 103 authorizes the board to investigate complaints, hold hearings, and impose discipline including suspension, revocation, and civil penalties.
Local jurisdictions may adopt local amendments to the electrical code, but statewide licensing under Chapter 103 preempts local licensing of electricians.
Continuing education and license renewal intervals are set by board rule; failure to renew within the grace period may require reexamination.
Unlicensed practice or contracting without a license is a violation subject to enforcement by the board and may be referred for criminal prosecution.
Iowa Administrative Code Chapter 401 - Licensing Requirements, Procedures & Fees
Iowa Administrative Code 401 IAC governs board procedures for electrician and electrical contractor licensing, including application, examination, and renewal.
Applicants must submit a completed application with documented hours of practical experience, fees, and proof of any required education before examination approval.
Examination is administered by a board-approved testing provider; passing scores and exam content outlines are published by the board.
License renewal cycles and required continuing education hours are specified in 401 IAC; late renewal may require payment of a penalty fee.
Reciprocity or license by endorsement may be available for licensees from jurisdictions with substantially equivalent requirements, subject to board approval.
Fees are set by rule and include application, examination, license issuance, and renewal fees; fee schedules are published by the board.
The board may deny, suspend, or revoke a license for fraud in obtaining the license, incompetence, or violation of the electrical code or board rules.
Licensees must notify the board of changes in name or address within the timeframe specified in rule, and contractors must report changes in responsible managing employee.
Iowa Administrative Code Chapter 403 - Education
Iowa Administrative Code 403 governs education and training requirements related to electrician licensing, including approved apprenticeship and instructional programs.
Approved educational hours may substitute for a portion of the required practical experience hours, as specified in the board's rules.
Instructors in approved programs must meet qualification standards set by the board, including documented field experience and instructional credentials.
Approved training programs must maintain records of attendance and completion and make them available to the board upon request.
Continuing education courses must be board-approved and cover topics such as code updates, safety, and technical electrical content.
Course providers must apply for approval and demonstrate that course content and instructional hours meet the board's criteria.
Apprenticeship programs must be registered and provide structured on-the-job training with documented supervision by licensed electricians.
The board may audit education providers and revoke approval for noncompliance with recordkeeping or curriculum requirements.
