If you receive the warning “Bell Box Not Responding” it’s possible that it could be the result of low batteries, or a weak connection between the device and Base Station.

Checking the Batteries

As a first step, we recommend ensuring that the batteries are correctly installed.

1. Slide the Bell Box up and off it’s bracket.

1. This may require gentle force to get it to slide upwards.

2. Unscrew the back panel to reveal the four (4) CR123A lithium batteries.

3. Remove a single battery from the Bell Box

4. Wait at least 15 seconds, then reinstall the battery

5. Now, you’ll want to test the Bell Box by placing your system into Test Mode using the Keypad

1. Menu > Enter Master PIN > Test Mode

1. You’ll know you’re in Test Mode when the Base Station announces it. You may also check the timeline within the SimpliSafe® Mobile App for a “User Initiated Test” event.

6. Press and release the test button on the top of the Bell Box

1. NOTE: If you press this button for too long it may emit a quiet chirp. Be sure to protect your ears while testing this device.

7. You should hear the Base Station announce “Bell Box” and see a timeline event within the SimpliSafe® Mobile App that reads “Bell Box Test”

If you do not hear the Base Station respond or see a timeline event for this test, it is likely the batteries for your Bell Box need to be replaced.

Checking the Placement of Your Bell Box and Base Station

If you have replaced the battery and are still encountering the ‘Not Responding’ error, it likely is the result of a weak connection to the Base Station. A weak connection to the Base Station can often be caused by something environmental, like brick walls or dense home construction. 

To test this, temporarily move the Bell Box closer to the Base Station and see if the error stops. If the device does work in a new location, it is likely the result of the environment near the prior location that is causing the conflict. You’ll have two options from here; Keep the Bell Box in its’ new location closer to the Base Station, or try to identify and clear the interference in the devices existing location. If you choose to keep the Bell Box in the location where it has encountered the error, you’ll want to look for environmental factors, such as dense building materials, or wireless devices that are nearby that could be interfering with the RF signal between the Bell Box and the Base Station. If you have any devices that output a wireless signal, we recommend trying to keep them at least 3-5 feet away from your siren. That should help to clear up communication between the device and the Base Station.
