Step-by-Step Solution
Check Base Station Power and Internet
The base station is the brain of your security system. Verify it is plugged into a working outlet and the power LED is solid. Check that the ethernet cable connecting it to your router is firmly seated at both ends or that WiFi shows connected. If the base station has cellular backup ensure the SIM is installed. Without a connected base station, sensors cannot report events and you will not receive alerts on your phone.

$5.99Verify All Sensor Status and Batteries
Open your security app and check every sensor. Each door sensor, window sensor, motion detector, and glass break sensor should show online with good battery. Replace batteries on any sensor showing low. For sensors showing offline check placement and range from the base station. Remove and re-pair persistently offline sensors. A single offline sensor can prevent the system from arming properly.

$83.98Test Arming and Disarming Modes
From the app or keypad arm in Home mode which activates entry sensors but not motion detectors. Then disarm. Next arm in Away mode which activates all sensors including motion. Walk through to test that motion detectors trigger and entry sensors report when opened. Verify the base station sounds appropriate warning tones and the app shows correct real-time status for each mode.
Verify Monitoring Service and Emergency Contacts
If you have professional monitoring verify your subscription is active in account settings. Confirm your emergency contact list is current with correct phone numbers. Test the monitoring connection by contacting your provider and requesting a communication test to verify the base station can send alarm signals. Update your home address if you have moved. Outdated contact info means delayed emergency response.
Test Siren, Notifications, and Delay Timing
Trigger a test alarm by opening a door while armed. Verify the siren sounds within the entry delay period, you receive a push notification, and if monitored the center calls you. Check that entry and exit delay times give you enough seconds to arm and leave or enter and disarm without false alarms. Adjust delay times in settings if needed. Most systems allow 30 to 60 seconds for entry and exit.
Update Firmware and Review Automations
Check the app for base station and sensor firmware updates. Install updates which improve sensor communication and fix security vulnerabilities. Then review automation rules such as lights turning on when motion is detected at night or doors auto-locking when you arm the system. Delete outdated rules and create new ones matching your routine. Test each automation to confirm it triggers correctly.
Quick Solutions
Still having issues? This is usually the deeper cause below.
If the keypad rejects valid codes, a lockout timer may be running — five failed entries locks most keypads silently for 5–10 minutes.
Write down your PIN and store it securely. If you forget it, you'll need to reset through the app or contact support. **Product Intelligence:** - 4x AA batteries - Within 100ft of Base Station
Three-beep rejections are usually a lockout nobody noticed — five wrong attempts locks the keypad silently and most users don't know the timer exists.
