Why does your smoke alarm start beeping when you use your treadmill?

The most likely reason your smoke alarm starts beeping when you are on the treadmill is it needs a new battery. It is a coincidence that you are on the treadmill when it is alerting you.

How often should smoke detector batteries be changed?

When the smoke detector first starts signaling low battery with short widely spaced high pitched chirps, or if when you press the test button the alarm does not trigger.After replacing the batteries, press the test button. If the alarm does not trigger with fresh batteries, replace the smoke detector.


How can you keep the smoke detector from beeping temporarily?

Push the button, or take the battery's out (not recommended) In many modern smoke alarms it is impossible to remove the battery, but there may be an on/off switch that can be actuated with a tool. If the alarm is beeping because the battery is dead, replace the battery or the entire alarm unit, which should be done every ten years anyway. Removing a battery in any smoke detector could be criminal "tampering", if anyone gets hurt because of it.


How do you change the battery in a smoke detector?

Smoke alarm batteries are easy to replace, once you find where they go. The design varies from brand to brand. Usually, the battery is located on the side of the alarm, either in a "drawer" or a swinging compartment. There may be a small plastic latch holding it closed. Occasionally, it is necessary to remove the alarm from the wall or ceiling to find the battery compartment. This can be done by rotating the entire alarm counter-clockwise until it releases. The battery compartment is designed not to close if the battery is inserted incorrectly. Many smoke alarms have an option to permanently screw the battery compartment closed. This is typically done in rental units to prevent tenants from removing the battery during a false alarm. In this case, the landlord is required by law to change the battery. If you are the landlord, consult the alarm documentation (which can be found online) for instructions on how to remove the locking screw.

Why does the smoke alarm keep chirping after installing a new battery?

Two thoughts: you may have put the battery in wrong (if it's not all the way in, they chirp) or you may have put in a dead battery.


Does an electric smoke alarm have a battery?

It depends on your city's fire codes, most likely yes. "Wired" alarms could either mean "wired to AC power" or "wired to an alarm panel" or both. Start by calling your local fire alarm installer or electrician. Assuming that the detectors are wired to a central hub in the house/building (fire alarm control panel), the panel would normally have a battery back-up installed. For individual units wired to AC, having a battery back up would be safer, no matter what the laws. Some units will automatically remind you when the battery is low, even though the unit is on AC power, since the smoke alarm must continue to function if power is off for some reason.
