1. Product Overview
The ELRO AS90S Home+ wireless alarm system is a reliable all-in-one solution designed to secure your home or office. This comprehensive system includes a base unit, a control panel, a motion detector, three door/window sensors, and a remote control. It is designed for easy self-installation, typically within 15 minutes, and can be expanded with additional sensors and accessories as needed.
Upon detection of an intruder, the base unit activates an audible alarm of at least 100 dB, sufficient to deter intruders. Additionally, you will receive an alarm notification directly on your smartphone. The ELRO Home+ alarm system features a backup battery and, with a GSM module (SIM card not included), ensures continued operation during power outages.
The dedicated ELRO Home+ App, available for free on the App Store and Google Playstore, allows you to arm and disarm the system remotely. It also sends push notifications for detected intrusions and enables easy adjustment of system and accessory settings.

8. Troubleshooting
This section provides solutions to common issues you might encounter with your ELRO AS90S Home+ alarm system.
8.1. System Not Responding
- Check Power: Ensure the base unit is properly connected to power and that the power adapter is functioning. Verify the backup battery is charged.
- Check Internet Connection: Confirm your home WiFi network is active and the base unit is connected. If using GSM, ensure the SIM card is correctly inserted and has active service.
- Restart System: Disconnect power from the base unit, remove the backup battery, wait 30 seconds, then reinsert the battery and reconnect power.
8.2. Sensor Not Triggering Alarm
- Check Battery: Replace batteries in the sensor if necessary.
- Check Placement: Ensure motion detectors are placed correctly to cover the desired area and that door/window sensors are aligned with a maximum 9mm gap when closed.
- Re-pair Sensor: If a sensor is not communicating, try re-pairing it with the base unit via the ELRO Home+ App. Refer to the app's instructions for pairing new devices.
- Check System Mode: Ensure the system is in the correct arming mode (Full Arm or Night Mode) for the specific sensor to be active.
8.3. App Connectivity Issues
