Fire Block Plans in Melbourne: What Goes at the Panel and How to Get One Drawn

A fire block plan is the orientation drawing that sits at your fire indicator panel (FIP) so arriving firefighters can work out, in seconds, where they are, where the alarm has come from, and where the hydrants, boosters and valves are. If your Melbourne building has an FIP, AS 1670.1 expects a block plan displayed at it, and a missing, faded or out of date plan is one of the easiest things for an inspecting officer to pick up.

Below is what the plan has to show, what makes one wrong, and what you need to send through to have one drawn.

What a block plan actually is

It is a simple plan view of the site, not an architectural drawing. It is drawn for someone who has never been to your building, standing in a smoke-filled lobby at 2am, trying to decide which way to walk.

A block plan will normally show:

• The outline of the building or buildings on the site, with the site boundary
• A north point, and the names of the surrounding streets
• The location of the FIP itself, marked "You are here"
• Alarm zone facilities and zone boundaries, labelled to match the panel
• Fire hydrants, hydrant and sprinkler boosters, and sprinkler control valves
• Fire brigade vehicle access, gates and any locked access arrangements
• Stairs, lifts and main entries where they help with orientation
• Level or building references where the site has more than one

The detail that matters most is the zone labelling. If the panel reports "Zone 7" and the block plan does not say where Zone 7 is, the plan has failed at the only job it has.

Block plan, evacuation diagram or flip chart?

These three get mixed up constantly, usually at the point someone is told "you're non-compliant" and does not know which document is being talked about. They are different documents, for different audiences, in different places.

Most sites need all three. If you are sorting out a compliance letter, it is worth checking which one is actually being asked for before you order anything. Our block plans and emergency evacuation diagrams are drawn separately for exactly this reason.

Who looks at block plans in Victoria

In practice, the people who notice a bad block plan are Fire Rescue Victoria or CFA crews attending an alarm, your fire protection contractor during routine servicing, and whoever is preparing the building's annual essential safety measures reporting. Maintenance of essential safety measures in Victoria sits under the Building Regulations, and the fire detection and alarm system is one of those measures, so the documentation at the panel tends to come up during that process.

One point worth being clear about: the Annual Fire Safety Statement is a New South Wales requirement, not a Victorian one. If you manage buildings in both states, the annual fire safety statement process applies to your NSW sites, while your Melbourne sites report under the Victorian essential safety measures framework. The block plan itself is required on both sides of the border because it comes from the alarm system standard, not the state regulation.

What makes a block plan fail

From the things that get flagged most often:

• Zones that do not match the panel. A tenancy is split, a zone is added, and nobody redraws the plan.
• Building works not reflected. New wing, new carpark, new booster location, old plan.
• Fading and UV damage. Panels near glazing bleach out. Red and orange go first, which is exactly what you need to read.
• No north point or street names. The plan is technically correct and practically useless.
• Mounted where it cannot be read. Behind the panel door, too high, or in a cupboard that is locked.
• Wrong scale of detail. Furniture layouts and room names crowd out the hydrants and zones.

Getting one drawn for a Melbourne site

You do not need to commission a new survey in most cases. The fastest path is usually:

1. Send what you already have. Architectural floor plans, fire services drawings, an as-built PDF, or even a clear photo of the existing block plan if one is up.
2. Send the panel zone list. A photo of the zone chart or the printed zone schedule inside the FIP is the single most useful thing you can provide.
3. Confirm the services. Booster location, hydrant locations, sprinkler valve room, and any brigade access arrangements such as key boxes or gate codes.
4. Confirm mounting. Where the plan will hang, and how much wall you have. Size is driven by how much site there is to show and how small the text would end up, not by a fixed rule, so a photo of the panel wall helps.
5. Check the proof. A draft comes back for someone who knows the building to mark up before printing.

Where drawings do not exist or the building has changed a lot, a site visit is the sensible option rather than guessing. Sites in regional Victoria can often be handled the same way as Melbourne metro if the information supplied is good.

Materials and mounting

Block plans are normally printed and laminated or mounted on rigid board so they survive being touched, wiped and knocked. In a plant room or an external FIP cabinet, ask for something that will not curl in the heat. If the panel is in direct sun, expect to replace the print sooner than you would indoors, and consider a location a metre either side rather than accepting the fade.

If you are ordering plans for a site, it is worth looking at your warden documentation at the same time, since the same site information feeds an emergency procedure flip chart and saves doing the work twice.

FAQ

Does every building need a block plan?
The requirement follows the fire alarm system. If the building has a fire indicator panel connected to the brigade, a block plan belongs at it. A small building with nothing more than smoke alarms and extinguishers will not have an FIP and so will not have a block plan, though it may still need evacuation diagrams.

How often does a block plan need updating?
There is no fixed expiry. It needs to be current, which means it is updated whenever the zones, the services or the building layout change, and replaced when it is no longer legible. Most sites review it at the same time as their annual fire system reporting.

Can I just amend the existing plan by hand?
Handwritten amendments on a laminated plan are a common short term fix and they are better than a wrong plan, but they do not last and they read badly during an inspection. If a zone has genuinely changed, get the drawing updated and reprinted.

If you are not sure which document your Melbourne site is short on, start with the full list of services and work from the panel outwards: block plan at the FIP, diagrams through the building, flip charts with the wardens.
