Fire systems are sourced from approved manufacturers through authorised channels, because certification and approved installer status are part of what is being bought.
Extinguishers, signage and emergency luminaires can be consolidated across sites; panels and detection equipment are matched to the approved system design.
Direct manufacturer supply is used where it is genuinely available for the category and volume. Where a brand supplies only through authorised partners, we buy that route to protect warranty and benchmark it so the difference is visible.
