About Fire Alarm Course

Fire Alarm Course is an engineering reference and educational site for working professionals in fire detection, fire alarm, and life safety systems. The site is run by John Kelly, a fire and security engineer based in Ireland with over twenty years of field experience across detection design, commissioning, and system specification.

What the site is for

The articles, guides, and glossary entries on this site are written for working engineers, designers, consultants, commissioning engineers, and informed facility managers. The aim is to provide deeper, applied treatment of detection and suppression topics than is usually found in product literature or short trade-press summaries, while staying clear of content that should rightly remain in the published standards (BS 5839, IS 3218, NFPA 72, EN 54, and others) rather than being paraphrased online.

The site is vendor-neutral. Where specific products are referred to, it is because they have become genericised within the trade (VESDA for aspirating smoke detection, for example), or because they are useful as concrete examples of a wider technology. Manufacturer rankings, comparisons, and recommendations are not part of the editorial remit.

Who writes the content

All content is written by John Kelly. The voice is deliberately that of one engineer talking to another: direct, technically precise, without the marketing register that has become standard in fire alarm trade content over the last decade. Where John does not have first-hand experience of a topic, the article says so plainly and points at the standards and the sources where the authoritative treatment lives.

What is on the site

The Guides section contains the major topic-area overviews: fire alarm fundamentals, addressable system architecture, aspirating smoke detection, voice alarm and emergency communication, and others. The Detection, Suppression, Applications, Troubleshooting, and Concepts sections contain the supporting articles that go deeper on specific technologies and design questions. The Glossary defines the trade vocabulary, acronyms, and standards-derived terms that recur across the site.

Fire Alarm Course currently focuses on free reference content. Structured online courses, where the design methodology and worked design examples will live, are in development.

Editorial principles

Three principles shape what gets published. First, usefulness to a working engineer: articles must say something the reader could not get from skimming the manufacturer's spec sheet. Second, copyright respect: standards text is not paraphrased here; the relevant clauses are pointed at, and engineers needing the authoritative wording are directed to the source. Third, vendor neutrality: the site does not rank, recommend, or compare specific manufacturers' products against each other.

Get in touch

Questions, corrections, or topic suggestions are welcome via the Contact page. The site benefits from feedback from working engineers; most of the deeper articles started as someone asking why something works the way it does, or pointing out where a published source had it wrong.
