You may be familiar with Nullifire's new Technical Drawing Details by now and they hope you’re finding these useful. Each of these documents contain a unique reference number, which you might not find very intuitive at first. This number serves as a key point for our Technical team's future interactions, enabling precise communication and problem-solving.

So, as promised, in this article Nullifire delve into the art of reading and interpreting these unique reference numbers in 8 steps, to empower you to navigate their technical documentation effortlessly.

1. Main Product

This refers to Nullifire's 5 digits product shortcut, for example:

• FB750
• FS709
• FS702
• FP302
• FP170

2. Substrate plus minimum thickness in mm

The substrate can be as per below:

• DW =Drywall
• RW = Rigid Wall
• CF = Concrete Floor
• PC = Plasterboard Ceiling
• MS = Multiple substrates

3. FB750 Construction Type (only when applicable)

The construction types refer to:

• SC = Single Batt Compressed DC = Double Batt Compressed DP = Double Batt Pattress CP = Compressed + Pattress
• BB = Batt box

4. Single / Multiple or Mixed Penetrations

Represented as:

• SI = Single
• MU = Multiple
•MI = Mixed

5. Penetration Type

Which are numbered as per below:

• Combustible pipe
• Non Combustible pipe
• Non Combustible pipes insulated
• Cables / Cable carriers
• Blank seals
• Dampers

6. The Second main product (when applicable) (5 digits)

This again, refers to Nullifire's 5 digits product shortcut, for example:

• FS709
• FP302
• FP170
• FI025

7. Unique number

And last but not least,

8. Type of document

At the moment this refers to:

• TD = Technical detail
• 3D = 3D detail
• 2D = 2D detail

Let's go through a few examples for better understanding…

FB750-DW100-DP-SI-01-00001-TD

This reference number refers to: FB750 - drywall 100 mm – double batt pattress – Combustible pipe - single penetration - technical detail.

FB750-DW100-DC-SI-04-FS709-00001-TD

This second example reads as follow: FB750 - drywall 100 mm – double batt compressed - cable – single penetration – cables - second product – technical detail.
