Key Takeaways
1Fire alarm symbols on UK drawings follow BS 5839-1 (commercial), BS 5839-6 (domestic) and BS EN 54 component standards.
2Smoke detector, heat detector, CO detector and aspirating detector symbols differentiate by internal element — circle with smoke streaks, circle with heat element, etc.
3BS EN 14604 covers single-station domestic smoke detectors required under the Smoke + CO Alarm Regs 2022 (England) — separate from BS 5839-1 commercial systems.
4Manual call points (break-glass) to BS EN 54-11 are required at every escape exit and on escape routes — symbol is a small square with a diagonal line representing the breakable element.
5Disabled toilet emergency call point symbols (BS 8300) include the pull-cord activator, reset button and exterior indicator/sounder.

Smoke Detector
An optical or ionisation smoke detector to BS EN 14604 (single-station, domestic) or BS 5839-1 (fire alarm system). Interlinked types signal one another via wire or RF.
Used in: Every level of a domestic property, escape routes, places of assembly per regulations.
A fire detector that triggers on a fixed temperature (typically 58°C) or rate-of-rise. Used where smoke detectors would false-alarm (kitchens, garages, dusty areas).
Used in: Kitchens, garages, lofts, plant rooms, smoking areas; never in dwellings without an SD elsewhere.
A carbon monoxide detector to BS EN 50291. Required in rooms with combustion appliances under the Smoke and CO Alarm Regs 2022 (England) and similar in Wales/Scotland.
Used in: Living rooms with gas fires, bedrooms above garages, rooms with solid-fuel stoves or boilers.
A combined audible + visual alarm device to BS EN 54-23. The visual indicator is required for the hearing impaired and in high-noise environments where audible signals alone may not be heard.
A manual call point to BS EN 54-11. The break-glass/press-glass element used to manually trigger the fire alarm system. Sited near exits and on escape routes.
Used in: Every fire-alarm system; on escape routes, at exits, at landing levels.
A disabled-toilet emergency assistance alarm to BS 8300. Pull-cord activator + reset button + indicator outside the WC. Required under Building Regs Part M.
Used in: Accessible WCs in commercial buildings, hospitality, public buildings.
A two-way emergency voice communication point at a disabled refuge to BS 5839-9. Allows people awaiting evacuation to communicate with the main control room.
Used in: Stairwells in multi-storey commercial buildings, evacuation lift lobbies.
A PIR or microwave motion detector for an intruder alarm system to BS EN 50131. Typically wall-mounted at 2.0-2.4 m with coverage of 12 m × 12 m for standard PIR.
Used in: Hallways, large rooms, garages; works with door contacts to form a complete zone.
A proximity card, fob or biometric reader controlling a maglock or electric strike. Networked to a central controller. Often integrated with the fire alarm for auto-release on alarm.
Used in: Office entrances, server rooms, restricted-access plant rooms, multi-tenant lobbies.
A green push-button that releases an electrically-locked door from inside (the egress side). Required where access control restricts movement out of a space.
Used in: Inside doors with maglocks/strikes, server rooms, secure office areas.
A domestic bell or chime triggered by a push-button at the door. Often supplied via a 12 V transformer in modern wired systems, or battery for wireless.
Used in: Front door, back door, tradesperson entrance; symbol used on domestic drawings.
A wall- or ceiling-mounted extract fan. Bathroom fans typically interlocked with the light circuit and overrun timer; kitchen fans on a separate switch.
Used in: Bathrooms, kitchens, WCs, utility rooms; needs 3-pole isolator for safe maintenance.
A wiring junction box where cables are joined. Must be accessible per BS 7671 526.3 unless maintenance-free (MF) type. Modern MF boxes use spring terminals.
Every life-safety and security symbol — fire detection to access control — drawn to BS EN 60617 with BS 5839, BS EN 54 and BS 8300 cross-references.
Each symbol is drawn to BS EN 60617 — the UK adoption of the international IEC 60617 standard for graphical symbols on electrical diagrams. The same symbols appear on EICR forms, distribution board schedules, single-line schematics and installation layout drawings.

Elec-Mate is my go to app for business and electrical work. It's feature rich without feeling cluttered. A true all in one app for quotes, certs, calculations, RAMS, EICRs, and more. I use it every day without fail, and it makes my workflow much smoother since I'm not jumping between apps anymore. The price-to-feature ratio is excellent. Any issues I've had, the developer responds within the hour and usually fixes them the same day. 100% recommend.
Fantastic app for electricians
I've used the app and the web based version for a while now and it's well worth the investment. If you're an apprentice or experienced Spark give it a go, you won't be disappointed.
Absolutely amazing
I've been using Elec-Mate for a while now, and honestly, it's one of the best apps I've ever downloaded. Every aspect of it feels thoughtfully designed, from the clean and intuitive interface to the powerful features that make everything so easy to manage. It's clear that a lot of care and attention went into building this app, and it shows in every detail.
