Fire alarm device layouts, loop and riser schematics, cause-and-effect and cable schedules, drafted in AutoCAD to your title block and symbols, so your engineers can stay on site.
We draft fire alarm drawings for fire and security integrators, M&E contractors and consultants in the UK, the US, the Middle East and beyond. You give us the design intent (a marked-up plan, a device schedule or the previous revision) and we turn it into a clean, consistent drawing set ready for submittal, installation or handover.
Fire alarm drawings are life-safety documents, so we keep the roles clear. We draft to your system design and to the standard your project works to, such as BS 5839-1 or NFPA 72. Detector selection, coverage, calculations and approvals stay with your designer and the authority having jurisdiction. Where a markup is unclear or clashes with the backgrounds, we raise an RFI instead of guessing.
Drafters who understand low-voltage and life-safety systems, not just CAD lines.
Your title blocks, layers and conventions, every time.
Delivered in days, quote in one business day.
Accurate, submittal-ready drawings, checked twice.
Backgrounds (DWG or PDF), your markups or design, your title block and the date you need the drawings.
We confirm the sheet list, price and delivery date within one business day, before any work starts.
Your title block, layers and symbol legend. Every sheet goes through a two-stage check.
PDF and DWG, an updated drawing register and a note of what changed since the last revision.
No. We draft to your design. Your fire alarm designer stays responsible for detector selection, coverage, cause and effect and calculations; we make sure the drawings show that design clearly and consistently, and we flag anything that looks inconsistent.
The one your project works to, such as BS 5839-1 in the UK or NFPA 72 in the US, using your symbol legend. If you do not have a legend, we set one up and agree it with you on the first sheet.
Yes. We draft the cause-and-effect matrix from your engineer's schedule and mark the interface points (door holders, lift recall, sprinkler flow switches, plant shutdown) on the plans, so installers can see where each interface physically sits.
Yes. Send red-line markups or photos of marked-up prints. We update device positions, addresses and cable routes and reissue the set with a clear revision note, ready for handover.
