Smoke Alarms & CO Detectors
Smoke & CO Detector Installation in Delta & the Lower Mainland
Licensed installation, replacement and wiring for hardwired smoke alarms, carbon monoxide detectors and compatible interconnected alarms in homes, suites, renovations, rental properties and strata units across Delta, Surrey, Burnaby, Richmond, Vancouver, Langley, Coquitlam and nearby Lower Mainland cities.
Hundel Electric reviews the property layout, existing alarm wiring, detector age, interconnection method and manufacturer compatibility before replacing or adding devices. Requirements can differ for existing homes, renovations, secondary suites and new construction.
Detector work may also connect with renovation electrical, an electrical safety inspection, electrical troubleshooting or a smaller electrical service call.
Residential alarm upgrades
Detector replacement is not always a simple one-for-one swap.
Hardwired alarms can be connected through an interconnect conductor, and replacement devices need to be suitable for the existing system. Older alarms may use different plugs, bases or signalling methods, while renovations and suites may require additional locations or new wiring.
Hardwired smoke alarm installation
Installation and replacement of hardwired smoke alarms in homes, suites and renovation projects, including review of power, mounting and interconnection.
Carbon monoxide alarm installation
CO alarm installation and replacement planning for properties with fuel-burning equipment, fireplaces, attached garages or other conditions requiring review.
Interconnected alarm replacement
Review of existing alarm wiring and device compatibility so interconnected alarms operate together instead of creating nuisance alarms or failed signalling.
Renovations, suites and rental properties
Alarm wiring and placement support for basement renovations, secondary suites, sleeping-area changes, rental-property upgrades and older homes.

Common alarm problems
Beeping can mean more than a low battery.
A periodic chirp may indicate a battery issue, end-of-life warning, lost power or device fault. Repeated alarms can also involve dust, moisture, incompatible interconnected devices, wiring problems or an actual smoke or carbon monoxide condition that must not be ignored.
End-of-life and battery warnings
Alarm service life and warning patterns vary by manufacturer. The model label and instructions should be checked before assuming a battery replacement will solve the issue.
Wiring and interconnection problems
Loose connections, failed power, incompatible devices or interconnect faults can cause nuisance alarms, chirping or alarms that do not activate together.
Service scope
Residential smoke and CO alarms are different from commercial fire-alarm systems.
This service focuses on residential and similar hardwired smoke and carbon monoxide alarms. Fire-alarm panels, supervised initiating devices, annunciators, verification, monitoring and commercial fire-alarm testing can require specialized equipment, documentation and qualified fire-alarm service providers.
Hundel Electric’s typical scope
Residential hardwired alarms, combination smoke/CO devices, interconnection review, replacement, renovation wiring, suite upgrades and basic electrical troubleshooting.
May require a fire-alarm specialist
Commercial fire-alarm panels, monitored systems, system verification, annual testing, programming, signalling devices and manufacturer-specific fire-alarm service.

Questions & answers
Common questions about smoke and CO detector installation
These answers explain common replacement, wiring and troubleshooting questions before a homeowner, landlord or renovator requests service.
Do smoke and carbon monoxide alarms expire?
Yes. Alarm service life varies by product, and devices should be replaced according to the manufacturer’s date label and instructions. A recurring end-of-life chirp will not normally be solved by repeatedly changing the battery.
Can you replace hardwired interconnected smoke alarms?
Yes. The existing power, interconnect wiring, plugs, mounting bases and device compatibility should be reviewed so the replacement alarms operate together correctly.
Why does my smoke alarm keep chirping?
Possible causes include a low or missing backup battery, end-of-life warning, lost AC power, device fault, loose connection or incompatible alarm. The chirp pattern and manufacturer instructions help narrow down the cause.
Do I need carbon monoxide alarms?
CO alarm needs depend on the property, fuel-burning equipment, attached garage, sleeping areas, renovation scope and applicable requirements. Hundel Electric can review the electrical installation, while final placement requirements may also involve the authority having jurisdiction.
Can you add smoke and CO alarms during a basement-suite renovation?
Yes. Suite and renovation work is a good time to review alarm locations, hardwired power, interconnection and compatibility before ceilings and walls are closed.
Do you service commercial fire-alarm systems?
This page covers residential smoke and CO alarms. Commercial fire-alarm panels, monitored systems, verification, annual testing and programming may require a qualified fire-alarm service provider.
What should I send for a smoke or CO detector quote?
Send photos of each alarm, the brand, model and date label, the number of floors and bedrooms, whether there is a suite or attached garage, your city and a description of any chirping or failed operation.
