CO Detector

If you see a “Malfunctioned” error for your Smoke Detector, Carbon Monoxide Detector, or Smoke & Carbon Monoxide Detector, that means that the device should be replaced as soon as possible. 

If your device is still within warranty, our Support team can send you a replacement.

You may encounter a constant yellow light that is not accompanied by a chirp on your Smoke Detector, CO Detector, or Smoke & CO Detector, or a blinking red light on your Smoke & CO Alarm Listener, accompanied by the app error “Tamper Detected”. This is an indication that the device is not fully attached to its bracket, and needs to be adjusted within its bracket to clear the error.

When placing your device back into its mounting bracket, make sure to twist it fully until you hear it snap into place. The warning light should stop immediately.

If you still see that light, it is possible that the mounting bracket itself may be screwed into your wall or ceiling too tightly, causing the plastic to warp slightly. It may help to unmount the unit and slightly loosen the screws. Then try mounting the detector again.

Once the device has been properly mounted, we recommend placing your system into Test Mode and testing your detector to ensure that it is working as intended. To place your system into Test Mode:

1. Locate your Keypad and press the Menu button

2. Enter your Primary PIN

3. Scroll until Test Mode is highlighted

4. Use the rocker and tap to the right to enter Test Mode

You’ll know you are in Test Mode when you see the circle on the Keypad, with the text “Test each device by pressing its button”.

Note: If you have monitoring, you will receive a robo call from the Monitoring Center asking you to confirm you have placed your system into Test Mode.

To test your device, hold down the TEST button on the device for about 1 second. Please note that pressing this button will invoke a loud chirp from your detector Smoke Detector, CO Detector, and Smoke & CO Detector - so be sure to protect your ears during this process. Your Base Station will also confirm the test was successful by announcing the product name. 

To exit Test Mode, pick up your Keypad and use the rocker to press the Exit option on the screen. 

Our Carbon Monoxide Detector sniffs out dangerous leaks that can happen in kitchens, fireplaces, basements, and more. Because it’s an invisible and odorless gas, Carbon Monoxide leaks could otherwise go undetected. 

We recommend having at least one per floor, in a bedroom or in a central location. The Carbon Monoxide Detector should only be installed or mounted to a ceiling to ensure adequate readings.

*This product is designed for residential use. When used in a commercial environment, it should be supplementary to your existing smoke and/or CO detectors and not your sole detector(s).

In accordance with National Fire Protection Agency (NFPA) guidance, SimpliSafe® recommends replacing your Carbon Monoxide Detector within five (5) years of the manufacture date (found on the label on the back of your device).

If you see the “Low Sensitivity" error for the Smoke Detector, Carbon Monoxide Detector, or Smoke & Carbon Monoxide Detector, that indicates that you need to clean your device so it can detect properly. 

To Clean the Device:

1. Twist the detector counterclockwise to remove it from its bracket

2. Remove a battery from the device to ensure it is not receiving power

3. Use your vacuum cleaner’s soft bristle brush to remove any dust buildup

4. Put the battery back into the device and place it back on its mounting bracket

Vacuuming the device monthly should prevent any dust/debris from building up, and can prevent the Low Sensitivity error from occurring. Never use water-based products to clean the Smoke and/or CO Detector, as this can damage the device.
