About this trade
Low-voltage and security work used to mean three separate phone calls — one for structured cabling, one for access control, one for CCTV. Some contractors now cover all three, and the job is finding the ones who can sequence cleanly with electrical and ceiling installs.
Syndex sends one request to every reviewed low-voltage member in your area. Each replies for themselves, and you see who said yes before you pick up the phone.

What to know when hiring
Four things GCs check before they sign.
BICSI vs electrical: who pulls what
Low-voltage permits are separate from electrical permits in Calgary. Confirm the sub knows the scope split and isn't waiting on the electrician to pull cable.
Pre-wire before drywall closes
Cabling runs need to be in the wall before insulation and drywall. Schedule the low-voltage sub the day after framing, not after paint.
Confirm platform certifications
Most access control and camera platforms require certified installers for warranty. Ask which manufacturers they're certified by.
Coordinate with the fire alarm vendor
If the building has an existing fire alarm system, any new device adds need ULC-verified programming. Get the fire alarm contact in the first meeting.
How Syndex works for this trade
Post the job once with the scope, the location and the start date. It goes to every reviewed low-voltage member who covers that part of Calgary, and you see the ones who reply Yes or Call me, with their contact details and, where we hold one, the date on their WCB clearance letter.
Name every scope in the request, cabling, access, cameras, fire alarm, so a crew that only does one of them can say so before you meet.
Frequently asked
Low Voltage / Security hiring — questions GCs ask first.
- Do low-voltage subcontractors handle fire alarm work?
- Some do and some do not. Fire alarm device work on an existing system needs ULC-compliant programming and testing. Put fire alarm in the request, and ask the crew who replies for the certified technician who will do it.
- Can the same sub handle data cabling and security cameras?
- Some contractors cover data, voice and security in one crew, others specialize. Name all of them in the request and the replies will tell you which kind you are talking to.
- How do I find a structured cabling contractor in Calgary?
- Post the job on Syndex with the drop count, the building and the start date. It goes to the reviewed low-voltage members who cover that area, and you call the ones who reply.
- Does Syndex cover access control reprogramming or service-only work?
- Yes. You can post service-only or repair-only requests. Subs reply if it fits their availability.
