- Base station volume set low
- Base tucked away/enclosed muffling the siren
- Only relying on the base siren
Problem Description
Your SimpliSafe siren is too quiet and you want it louder. Check the base station volume setting first — the siren volume is controlled from the keypad or the SimpliSafe app. The base station has a built-in 95dB siren. If you need louder coverage, SimpliSafe sells an auxiliary siren (105dB) that pairs with the base station. This guide covers volume settings and adding an extra siren.
Why This Happens in Real Homes
The base station's built-in siren is loud, but two things make it seem quiet: the volume setting is turned down, or the base is tucked in a cabinet or closet that muffles it. It also has to fill the whole house from one spot.
Start by raising the siren volume in the base station settings and moving the base into the open rather than an enclosed space. For a large or multi-story home, one base siren won't reach everywhere — adding SimpliSafe's extra sirens gives audible coverage where the base alone falls short.
Symptoms
- Siren too quiet
- Alarm not loud enough
- Volume seems low
- Cannot hear it in other rooms
- Base siren muffled
- Only keypad chimes loud
- Want a louder alarm
- Siren volume will not change
Recognize these? Here's what usually causes it.
Common Causes
- Base station volume set low
- Base tucked away/enclosed muffling the siren
- Only relying on the base siren
- Large home needs extra sirens
- Volume setting controls chime too
- Base placement absorbing sound
- Firmware/setting issue
- Expecting more from one base
Most fixes happen in the first 3 steps.
Always notify your monitoring provider before performing system tests to prevent dispatching emergency services unnecessarily. Never disable your security system for extended periods. If you smell gas or suspect a real emergency call 911 directly rather than relying on your smart system.

Step-by-Step Solution
Check the base station volume setting
The SimpliSafe base station has a volume setting that controls the siren output and keypad sounds. On the keypad, go to System Settings and check the volume level. Set it to maximum for the loudest siren. Some users accidentally reduce the volume while adjusting other settings, which makes the alarm siren much quieter than its rated 95dB.
Check the base station location
The siren is built into the base station. If the base station is in a closet, behind furniture, or in a corner, the sound is muffled. Move the base station to an open location, ideally in a central hallway at chest height. Sound travels better from a central, unobstructed position. An open hallway amplifies the siren naturally.
Add the SimpliSafe Extra Siren
If the built-in siren is not loud enough for your space, SimpliSafe sells an additional wireless siren accessory (105dB). It plugs into a wall outlet and pairs with your base station. When the alarm triggers, both the base station siren and the extra siren sound simultaneously. Place the extra siren in a different part of the home for better coverage — near bedrooms or the garage entry.
Test the siren at full alarm
The siren may seem quieter during test mode than during an actual alarm. Some SimpliSafe systems reduce siren volume during testing. To hear the full volume, trigger a real alarm (open a door while armed and let the entry delay expire without disarming). Be prepared — the full-volume siren is very loud. Notify neighbors and any monitoring service before testing.
Check for a failing speaker
If the siren used to be louder and has gotten quieter over time, the speaker in the base station may be degrading. This happens after several years, especially if the siren has been triggered many times. A buzzy or distorted siren is another sign of speaker wear. Contact SimpliSafe for a replacement base station if the speaker is failing.

Still having issues? This is usually the deeper cause below.
If this comes back after following these steps, check whether a recent app or firmware update reset a default setting — the fix works, but the setting gets reverted silently.
Set up geofencing so your system arms automatically when everyone leaves home and disarms when the first person returns. This eliminates the chance of forgetting to arm the system and provides seamless daily security.
This issue almost always looks more complex than it is — the majority of cases trace back to a single setting, a stale credential, or a default that shipped wrong.
