Congratulations on purchasing the Original SimpliSafe® security system! Peace of mind is important, and now whenever you are away from home you will be at ease knowing your house is protected. This page will walk you through the installation and setup for your new system. In addition to following this guide, please download our step-by-step setup guide: Original SimpliSafe® Setup Guide.

Installing your SimpliSafe system has three core steps and one optional step: 

  1. Install Core Devices

    • Base Station

    • Keypad(s)

  2. Install Other Devices

  3. Activate Monitoring (Optional)

  4. Test Your System 

Install Core Devices

The first step to installing your SimpliSafe® security system is to set up your Base Station. We recommend installing it in a central location to ensure that you can hear it’s built in 85 decibel siren from anywhere in your home. We also advise users to install the Base Station 3-5 feet off of the floor, and 5 feet away from all major electronics. 

First, you will want to remove the Base Station from the box. Next, plug the Base Station into a power outlet using the power adapter included in the packaging.The Base Station will display a blue light, and provide a voice prompt stating that your Base Station is in test mode. Once your Base Station is finished speaking you can continue with installing your core devices. 


The next step to installing your Original SimpliSafe® security system is to install your Keypad(s). First, pull the battery tab from the Keypad that you are installing. The Keypad screen will display, “Welcome to SimpliSafe®.” Remove the liner from the adhesive strips attached to the Keypad bracket, and adhere it to the wall. Press and hold the Keypad to the wall for 30 seconds to ensure that it is firmly attached to the wall. The Keypad comes with screws for installation as well if you would prefer your Keypad to be more secure. Simply slide the Keypad up off of it’s bracket, and you can screw the Keypad bracket to the wall. Once the bracket has been screwed into the wall slide the Keypad back on to it’s bracket. We suggest installing your Keypad near the door you use the most to enter and exit your home.



Install Other Devices

For all sensors other than the Base Station, initial Keypad, and Cameras, follow the below instructions on where and how to install them.

Once you've installed the rest of your sensors we suggest installing your Cameras. For Indoor Cameras, refer to this article. For Video Doorbell Cameras, refer to this one.

*Please note that we no longer offer CO Detectors for the Original SimpliSafe® system. If you are having an issue with your Original SimpliSafe CO Detector, please contact support to find out how to upgrade your system.

Activate Monitoring (Optional)

Once you’ve finished installing your system, activate monitoring by visiting https://simplisafe.com/activate. You may need the serial number listed on the bottom of your Base Station.

We strongly recommend that you subscribe your security system to professional monitoring. Our monitoring centers are open 24 hours a day 365 days a year, so you can be confident whether you are at work or going to sleep that your home is protected. You can be notified immediately via email or text message as well with push notifications, if you are enrolled in our interactive professional monitoring. Still uncertain about professional monitoring? We’ve written up the top reasons you should get it.

Test Your System

We recommend testing your sensors and system to ensure that you have installed everything correctly. Test mode can be accessed by navigating the menu of your Keypad.

  1. Press Menu.

  2. Enter Your Primary PIN (If not set up the default PIN is 1234).

  3. The Keypad screen will display, “To navigate menu use keys below icons.” 

  4. Press “5” on your Keypad.

  5. Test your sensors. 

If you are subscribed to professional monitoring a test signal will appear in your online dashboard.


Press Menu on your Keypad twice to exit test mode. 

Congratulations! Your home is now protected with SimpliSafe®.
