Public Safety Radio Compliance in Delta
Delta Fire Regulation Bylaw No. 5855, 2001 — Section 14 (Radio Amplification Requirements)
The Corporation of Delta sets in-building first responder radio requirements under Delta Fire Regulation Bylaw No. 5855, 2001 — Section 14 (Radio Amplification Requirements).
Where a building may cause poor radio communications for first responders — or where directed by the Fire Chief or designate — the building owner must ensure the building meets a minimum standard of Delivered Audio Quality (DAQ) 3.4.
Fraser Valley RF Solutions supports Delta projects with verification testing, commissioning support, corrections/optimization, and annual compliance testing documentation.

Delta requirements at a glance
For Section 14, Delta defines Delivered Audio Quality of 3.4 as speech over radio that is understandable without repetition (with possible noise/distortion).
If the requirement is triggered, the owner must ensure:
All areas of the building meet the minimum standard DAQ 3.4, certified by a professional engineer registered in BC.
Continual monitoring is always active for any system put in place to ensure DAQ 3.4 is met.
Annual maintenance and testing is conducted by a professional engineer registered in BC to ensure DAQ 3.4 is met.
A record of the annual maintenance/testing is kept and available for inspection by the Fire Chief or designate.
When is a radio amplification system required in Delta?
Delta’s trigger is performance/impact-based. Section 14 applies when:
a building may cause poor radio communications for first responders, or
the owner is directed by the Fire Chief (or designate) to meet the requirement.
Practical takeaway: it’s smart to plan early (pathways, equipment space, and coordination) so you’re not solving the problem late in the project.
What buildings are exempt?
Delta’s Section 14 (specifically 14.2, 14.3, and 14.4) does not apply to:
any building that is no more than three storeys in height with a total floor space no more than 400 m², or
any building that meets all of the following:
constructed entirely of wood frame
no metal cladding
no Low-E reflective glass
no portion of the building with a floor level partially or wholly underground
less than 5,000 m² combined floor space
less than 12 m in height (lowest ground elevation to highest point)
If the building fails DAQ 3.4: what happens?
If a building fails to meet DAQ 3.4, the owner must:
notify the Fire Chief as soon as practicable, and
make repairs/works within five business days to meet DAQ 3.4.
If the owner fails to complete the works to the Fire Chief’s satisfaction, the Fire Chief may have a temporary radio amplification system installed at the owner’s expense, recoverable as a debt (and potentially collected like property taxes).
Delta also includes a clause where, if a new building is deemed to have caused a decline below DAQ 3.4 in an existing building, the owner of the new building must provide repairs/works to return the existing building to DAQ 3.4 to the Fire Chief’s satisfaction.
