| PST-WG103T Product FAQ | |
| Q1: What is this product? A: It's a Tuya - powered GSM alarm system. It uses GSM and Tuya smart tech to monitor your home/property, with functions like arming, disarming, and sending alerts. |
|
| Q2: Which networks does the GSM alarm system support? A: It typically supports 2G/3G/4G GSM networks. But PST-WG103T supports 2G GSM 850/900/1800/1900MHz). |
|
| Q3: Can it work with WiFi only, without GSM? A: Yes, GSM network is for calling and sending SMS alert; |
|
| Q4: Is it compatible with all Tuya - enabled devices? A: It works within the Tuya smart ecosystem. Most Tuya - certified sensors/devices can integrate, but double - check compatibility in the Tuya app or with us. |
|
| Q5:What’s the power supply for the main unit? A: The main alarm panel is powered by a DC adapter 5V 2A . It also have a backup battery 3.7V 1000mA for power outages. |
|
| Q6: How to install the main alarm panel? A: Fix it on a wall (ideally near the entry, at eye level) with screws. Connect the power adapter, insert a valid GSM SIM card (with call/SMS plan), then follow Tuya app setup steps. |
|
| Q7: How to pair sensors (door/window, PIR) with the main unit? A: Put the main panel in pairing mode (via menu or app). Activate the sensor (e.g., open/close door sensor, trigger PIR). The panel should detect and pair them automatically. |
|
| Q8: Can I install it outdoors? A: The main panel is for indoor use (to protect from weather). Outdoor - rated sensors (if available) can be placed outside, but check their IP rating (e.g., IP65 for water/dust resistance). |
|
| Q9: Do I need a professional installer? A: Basic installation is DIY: mount the panel, pair sensors, set up Tuya app. But if you’re unsure about wiring/SIM setup, consult a pro or the seller’s support. |
|
| Q10: How to connect to the Tuya app? A: Download the Tuya Smart app. Power on the alarm panel, open the app, add a new device (scan QR on the panel or search for “GSM Alarm System”), and follow the in - app pairing guide. |
|
| Q11: What do “Arm/Disarm”, “Away arm”, “Home arm” mean? A: Arm/Disarm: Full on/off of the alarm. Away arm: Activates all sensors (for when you’re out, e.g., PIR, door sensors). Home arm: Maybe disables some sensors (like PIR inside, so you can move around at home but door sensors still work). |
|
| Q12: Can I set auto - arming/disarming schedules? A: Yes, in the Tuya app. You can schedule times for the system to arm (e.g., nightly) or disarm (e.g., when you usually get home). |
|
| Q13: Does the sensor work with voice assistants? A: It supports Amazon Alexa and Google Assistant. |
|
| Q14. Does it support voice prompts? A: Yes, the main panel has voice prompts for status changes (e.g., “System armed”, “Sensor triggered”) to help you know operations. |
|
| Q15. What triggers an alarm? A: Opening a door/window (if sensor is armed), motion detected by PIR (in away/home arm modes), or pressing the panic button. Also, tampering with the panel or low battery can trigger alerts. |
|
| Q16. How to stop an alarm once triggered? A: Disarm the system via keypad, remote, or Tuya app. Enter the correct PIN or use authorized disarm methods to silence it. |
|
| Q17. What if my WiFi network is a 5GHz network? This sensor typically only supports 2.4GHz WiFi networks. You may need to switch to a 2.4GHz band or use a dual - band router's 2.4GHz option. |
|
| Q18. Can I get alerts on my phone even if I’m abroad? A: Yes, as long as your phone has network (cellular/WiFi) to receive Tuya app notifications or SMS/calls (if your GSM plan works internationally). |
|
| Q19. Can someone else access my sensor's data? A: As long as you keep your app account credentials secure, and your Wi - Fi network is protected, it's very unlikely that others can access your sensor's data. |
|
| Q20. Can I share the sensor data with other family members? A: Yes, in the Tuya Smart app, there's an option to share the device with other users. You can add their email addresses or phone numbers associated with their Tuya accounts. |
|
| Q21. System won’t arm. What to do? A: Check if all sensors are closed/normal. Ensure no low - battery alerts. Restart the panel (unplug power, wait, replug). If issue persists, reset to factory settings (via menu or app) and re - set up. |
|
| Q22: No SMS/call alerts. Why? A: Check SIM card: valid, has credit, correct APN settings (if needed). Ensure preset numbers are correct in the app. Test GSM signal strength (check panel’s signal icon). |
|
| Q23:Tuya app can’t connect to the panel. How to fix? A: Ensure panel is powered on and GSM/WiFi (if applicable) is working. Restart your phone and the app. Re - add the device in the app or check for firmware updates. |
|
| Q24: Sensor not working. What’s wrong? A: Check sensor battery (replace if low). Re - pair the sensor with the panel. Ensure no physical obstructions (for PIR, keep it clean and unblocked). |
|
| Q25: The sensor is not showing up in the app. What should I do? First, make sure the sensor is powered on and in pairing mode. Check your WiFi connection and try resetting the sensor by pressing the reset button for a few seconds. Then, try adding the device again in the app. |
|
| Q26: The anti - tamper function is triggering falsely. What could be the problem? A: Make sure the siren is properly mounted and not loose. Sometimes, vibrations from nearby machinery or heavy traffic can cause false detections. Check the mounting and consider adding additional stability if needed. |
|
| Q27: The sensor is offline in the app. How do I fix it? Check your WiFi router to ensure it's working properly. Try restarting the sensor and the router. If it's still offline, check the sensor's connection settings in the app. |
|
| Q28: The app is not receiving notifications from the siren. What can I do? A: First, check your app's notification settings to ensure they are enabled for the alarm system. Also, verify that the siren is connected to the WiFi network and has a stable connection. If the issue persists, try logging out and logging back into the Tuya app. |
|
| Q29. Can make OEM? A: Yes, we can. PID OEM:500PCS Box & manual OEM: 1000PCS, if only 500PCS extra charge 0.5USD/PCS; Laser Logo: 100PCS |
