What Voltage Are Hardwired Smoke Detectors

By | August 3, 2022



Smoke detectors save lives, and as such, it’s important that you know what voltage power supply your smoke detector needs. Hardwired smoke detectors require a specific voltage level in order to function correctly, and while this voltage is typically consistent throughout the nation, it is still important to check your specific smoke detector’s manual to ensure that you are using the right voltage.

Typically, hardwired smoke detectors require 120 volts of electricity, though some detectors may require a 24-volt transformer. It’s also important to note that smoke detectors should never be plugged into an outlet, as regular household voltage can be too hot for smoke detectors, potentially causing them to malfunction over time.

When it comes to the safety of your home or business, it’s essential to make sure your smoke detector is operating at the correct voltage. By ensuring that your smoke detector is properly installed and powered, you can rest assured knowing that it will be able to alert you if a fire does occur. Check your smoke detector’s instructions and contact your local electrician if you have any questions about the voltage for your smoke detectors.
