Why 3G’s sunset could leave your fire alarm signals in the dark.
Canada’s major telecom providers are in the process of shutting down their 3G networks. While most people think of this change in terms of cell phones, there’s a critical detail that’s often overlooked: many fire alarm panels, intrusion monitoring systems, and security communicators still rely on 3G SIM cards to transmit signals to central monitoring stations.
Why This Matters
- Fire alarm systems on 3G: Once the network is decommissioned, panels using 3G communicators will no longer send alarm signals.
- Non-ULC systems: If 3G is the sole communication path, there will be no automatic notifications to emergency services, property staff, or owners during a fire alarm or break-in.
- ULC-certified systems: ULC standards require two communication methods (commonly 3G plus a phone line or internet). If 3G is one of them, the system technically still works—but certification requires both paths. You’ll only have 15 days to correct the deficiency before losing ULC compliance.
Losing ULC certification can trigger higher insurance premiums and force costly administrative changes, such as updating fire safety plans and condominium declarations.
A Common Issue for Building Owners
We’ve seen many property managers only become aware of this issue when their provider notifies them—often after the shutdown has already started. This leaves buildings scrambling to schedule upgrades, risking lapses in coverage or losing their ULC status. Given how critical fire and intrusion monitoring is, these delays create unnecessary risk.
What SMS Recommends
The most important step is to confirm how your panel currently communicates:
- Ask your provider if your system uses 3G for primary or backup communication.
- Schedule an inspection to confirm if your equipment is compliant.
- Plan upgrades early to avoid last-minute disruptions and loss of certification.
If you’re unsure who your provider is, SMS can help. We’re offering no-cost inspections to confirm whether your system is up to date. In addition, when you sign a three-year contract with us, you’ll receive six months of free fire alarm monitoring as well as complimentary elevator phone monitoring for the full duration of the agreement.
Staying Ahead of the Change
The 3G shutdown is already underway, and networks will continue to be decommissioned over the coming months. By acting now, building owners and managers can:
- Maintain continuous alarm monitoring and life safety coverage
- Protect their ULC certification (and avoid insurance implications)
- Eliminate last-minute disruptions and unnecessary risks
Don’t wait until the network goes dark. Contact SMS today to schedule your inspection and keep your monitoring systems reliable, compliant, and ready when you need them most.
