Fire Alarm Zone

Paint detection zones, wire BS EN 54 devices onto loops, place panel markers, and export a per-marker zone plan.

The Fire Alarm Zone engine colours rooms by detection zone and produces a panel-ready zone plan. See the feature overview; this is the how-to.

Add the engine

Add the Fire Alarm Zone engine and set the region so the footer cites the right standard.

Zones

Use the Zones mode:

1. Create a zone — it gets the next number automatically, plus an optional name and a fill colour.
2. Arm a zone and tap rooms to paint them; each assigned room fills with the zone colour and shows the zone number in a white badge at its centre.
3. Erase clears a room’s zone. Each room belongs to at most one zone.

Fill opacity is adjustable plan-wide (default 30%). Edit a zone’s number, name or colour from its pencil; deleting a zone clears its room assignments.

”You are here” markers

Place up to four markers for panel and repeater locations. Markers drag to reposition, and each one becomes its own page in the export — so one plan can be posted in several places, each oriented to its viewer. A marker’s caption is editable and appears on the plan and as the PDF page caption.

Devices & loops

Switch to Devices mode for the addressable layer:

• Device catalogue (the BS EN 54 family): smoke detector, heat detector, multi-sensor, manual call point, sounder, sounder/beacon, beacon (VAD) and control panel. Each draws as a recognisable shape (detector = circle, call point = square, alarm = triangle, panel = rounded rectangle) with its abbreviation.
• Loops — create SLC loops (numbered, with a bold colour). Arm a device type and loop, then tap to place devices.
• Wiring — each loop draws a dashed line connecting its devices in placement order, in the loop colour. Deleting a loop unlinks its devices (they stay, just unlooped).

Compliance

The region drives the cited standard and a completeness checklist:

Completeness warnings nudge you toward a full plan — zones defined, rooms assigned, site and installer details, at least one marker — and flag a duplicate zone number.

Export

Export a multi-page PDF — one page per marker (a single page when none), A4 landscape (US Letter for the US region). Each page has a header (title, site, standard, revision, date), the plan with the zone fills under the linework and that page’s marker, and a footer with the zone legend, the device/loop key, the compliance statement, installer details, a north point and a scale bar.
