Calgary Hardwired Smoke Alarms
& Carbon Monoxide Detectors
Code-Compliant, Interconnected Life Safety Systems for Residential Properties
When it comes to protecting your family from fire and invisible, odorless carbon monoxide (CO) gas, reliable infrastructure is everything. Battery-only detectors or outdated, standalone retail units do not meet modern Alberta Building Code standards for residential properties.
Today, provincial and municipal regulations mandate that smoke and carbon monoxide detectors must be hardwired directly into your home’s electrical system and completely interconnected with a dedicated signal wire. This ensures that if a sensor is triggered in a basement laundry room or utility space, every single alarm throughout the entire house sounds simultaneously, granting your household maximum evacuation time.
At Electrek, our certified electricians specialize in retrofitting interconnected safety arrays, replacing expired sensor units, and ensuring secondary basement suites fully comply with strict City of Calgary safety codes.
Complete Life Safety Services We Provide
We manage the layout, wiring integration, and lifecycle maintenance for your home's early detection devices:
Interconnected System Retrofits
We fish specialized 3-conductor structural cables behind your drywall to establish a permanent communication link between alarms across multiple floors. If you are developing a basement development, we ensure the new suite links seamlessly to the upper levels as required by law.
Dual-Sensor Smoke and CO Combo Installations
We install advanced, commercial-grade life safety fixtures utilizing both photoelectric sensors (optimized for detecting slow, smoldering house fires) and electrochemical cells designed to spot dangerous levels of carbon monoxide leaking from furnaces or attached garages.
Comprehensive Compliance Inspections
Are you putting your property on the real estate market or changing insurance providers? We perform system audits to verify that your alarm placement adheres precisely to national standards, documenting that devices are located correctly within 5 meters of all bedroom doors.

Understanding Detector Lifespans & Expiration Dates
Smoke Detector Sensors ➔ Expire every 10 years (Accumulated dust & degradation)
Carbon Monoxide Sensors ➔ Expire every 5 to 7 years (Chemical cell exhaustion)
Backup Batteries ➔ Require replacement every 12 months (Even on hardwired systems)
A common homeownership oversight is assuming that if a test button makes a sound, the device is fully operational. The test button only checks the audible siren and electrical loop—it does not test the effectiveness of the internal sensing chamber. Over time, airborne dust, cooking grease, and chemical breakdown render sensors blind. If your detectors are over a decade old, they must be completely replaced.
Frequently Asked Questions
Why do my hardwired smoke alarms have batteries in them?
The line-voltage electrical feed powers the device day-to-day. The internal 9V or sealed lithium cell serves as an essential backup battery array. If a major structural fire or storm knocks out your main electrical panel, the backup system ensures your alarms continue to monitor the air and sound warnings.
What are Calgary’s strict rules for legal basement suite alarms?
The City of Calgary mandates that secondary suites must have hardwired, interconnected smoke and carbon monoxide alarms protecting both the primary residence and the suite. Furthermore, they must be isolated onto circuits that cannot be easily turned off by a tenant (such as sharing a circuit with a frequently used lighting zone).
Why is my detector making a short chirping sound every few minutes?
A single, rhythmic chirp is typically a warning indicator that the backup battery is low, or that the internal sensor assembly has reached its manufacturer expiration date. The Electrek team can instantly troubleshoot your system configuration to diagnose whether it requires a quick power cell swap or a full system upgrade.
