Most property owners know to test their smoke detectors twice a year, but many don't realize that the units themselves have an "Expiry Date."
A standard smoke detector has a 10-year lifespan. Even if the battery is brand new, the internal sensors degrade over time due to:
➡️ Accumulated dust and debris
➡️ Fluctuations in humidity
➡️ Sensory fatigue
🔥 Pro-Tip for Property Managers: Take a unit off the bracket and check the "Date of Manufacture" on the back. If it was made over a decade ago, it is no longer reliable and needs a full replacement.
Action: Is your building's detection system reaching its 10-year mark? We can help with a full-system audit.
