How to Test Your Security System Monthly
Safety Warning
Do not test your security system by triggering the alarm without notifying your monitoring company first, as this will likely generate a false emergency dispatch and may result in fines. Always contact your monitoring service before testing and use the "Test Mode" feature on your panel if available. If your system uses cellular or internet backup, ensure these are not disabled during testing. Never attempt to test gas sensors, CO detectors, or smoke detectors by actually exposing them to their triggering substances—use the test buttons only. If you're unsure how to properly test your system, contact your security provider for guidance rather than risking false alarms or liability issues.
A security system only protects your home if it's working properly, yet many homeowners never verify their sensors and cameras function correctly. Testing your system monthly takes less than 30 minutes and ensures you'll actually be alerted if something goes wrong. Anyone with access to your security panel and system documentation can perform these tests safely.
What You'll Need
Supplies
- •Replacement batteries for wireless sensors (CR2032 coin cells)(optional)($5-10)
- •Compressed air canister for camera lens cleaning(optional)($4-8)
Tools
- •Mobile app for your security system (provided by your monitoring company)
- •Flashlight or mobile phone light(optional)
- •Soft cloth for cleaning camera lenses(optional)
Step-by-Step Instructions
Review Your System Documentation
Locate your security system's user manual, installation paperwork, or contact information for your monitoring company. Find the test mode instructions, the list of all sensors and their locations, and emergency contact numbers. Having this information ready prevents confusion during testing and ensures you follow the manufacturer's recommended testing procedures.
Pro Tip: Take a photo of your system's serial number and model from the panel—you'll need this if you call your monitoring company for guidance.
Notify Your Security Monitoring Company
Call your security provider and inform them that you're performing a monthly system test and request that they not dispatch emergency services if the alarm sounds. Provide your account number and the time window you'll be testing. Most companies have a specific protocol for test mode that prevents false dispatch, so ask them to confirm when it's safe to proceed.
Pro Tip: Many modern security companies allow you to activate test mode through their mobile app—check if this option is available before calling.
Test Door and Window Sensors
Starting with one entry point at a time, open each door or window while watching your security panel for a sensor alert. The panel should display the name or zone of the opened door/window within 2-3 seconds. Close the door and verify the sensor shows as closed on the panel. Repeat this process for all perimeter doors and accessible windows.
Pro Tip: If a sensor doesn't respond, check that batteries in wireless sensors haven't died—most wireless door sensors use CR2032 coin batteries that last 3-5 years.
Test Motion Detectors
Arm your system in test mode, then move slowly through each room with a motion detector. The panel should register the motion detection zone activating. Move deliberately within the sensor's field of view for at least 5-10 seconds to ensure it's properly calibrated. Disarm the system after testing each motion sensor.
Pro Tip: Motion detectors can have blind spots due to furniture or room layout—walk multiple patterns through the room to verify coverage, especially near entry points.
Test Security Cameras
Check each camera's view on your security panel or mobile app to confirm it's receiving a clear video feed. Ensure nothing is blocking the lens due to dust, spiderwebs, or objects. Verify that the camera's night vision or infrared mode activates if your system has it. Test any pan-and-zoom functions if available.
Pro Tip: Clean camera lenses with a soft, dry cloth or compressed air—visible dust or cobwebs will reduce image quality and defeat their security purpose.
Test the Alarm Panel Itself
Access your system's test mode menu on the control panel using your master code or through the mobile app. Run the system's built-in diagnostic test if available, which automatically checks all connected sensors and devices. The panel should display the status of every zone—any zones showing as 'not communicating' or 'failed' indicate a problem needing attention.
Pro Tip: Document the date and results of your test in a log—this creates a record of system health and helps you notice patterns if specific sensors fail repeatedly.
Test Battery Backup and Communications
If your system has battery backup, check the panel display to confirm the battery status shows as 'good' or 'fully charged.' For monitored systems, verify the communication status shows 'armed' or 'connected' rather than 'communication failed.' If using cellular backup, check that both internet and cellular connection icons are active on the panel.
Pro Tip: If battery backup shows as weak or failing, contact your monitoring company for a replacement—a depleted backup battery means your system won't work during a power outage.
Document Results and Create Maintenance Reminders
Write down which sensors, cameras, and functions worked properly and note any that failed or responded slowly. Set a phone reminder to repeat this test monthly on the same date. If any zone failed testing, contact your security provider immediately to schedule service rather than leaving a gap in your protection.
Pro Tip: Take a screenshot of your test mode results from the panel or app—this provides proof of your monthly testing if ever needed by insurance or law enforcement.
