2.2 Initial Setup
- Insert SIM Card: Insert a valid SIM card into the designated slot on the back of the main panel.
- Connect Power: Plug in the power adapter to the main unit. All LED lights will illuminate for 2 seconds, followed by a long beep.
- System Initialization: The system will enter initialization mode. The LCD screen will display the time, and the [SGM] indicator will flash as the system detects the GSM network. Once a long beep sounds and the [SGM] indicator turns off, the system is in disarm status.
- Activate Backup Battery: Turn on the backup battery switch located on the back of the main panel.
2.3 GSM Signal Checking
Before final installation, check the GSM signal strength to ensure optimal performance:
- In setup status, input
[81]then[#]. - The main unit will beep and display
00+XX(where XX is the signal intensity). - The intensity should be between 07-31. If it's less than 07, consider relocating the panel.
2.4 Coding Remote Controllers and Detectors
Remote controllers and wireless detectors must be coded to the alarm host to function correctly.
Coding Remote Controllers:
- Enter setup state (see Section 3.1).
- Input
[0201]. - Press any button on the wireless remote controller.
- The main unit will beep and announce "coding completed".
Coding Wireless Detectors:
- Enter setup state (see Section 3.1).
- Input
[0202]. - Trigger the wireless detector (e.g., open a door sensor, activate a PIR sensor).
- The main unit will beep and announce "coding completed".
2.5 Wired Terminal Block Connection
The system supports 7 wired defense zones. Refer to the diagram for connecting wired sensors:
Connect wired sensors (e.g., loudspeaker, wire PIR sensor, wire siren, wire water sensor, wire smoke sensor, wire glass sensor) to the corresponding terminals (LB+, LB-, GND, Z1-Z7, SP-, SP+).
3. Operating Instructions
3.1 Entering/Exiting Setup Mode
- Enter Setup: In disarm status, input your 4-digit password (default:
8888) and press[#]. The system will announce "please enter instruction" and the [SET] indicator will light up. - Exit Setup: Press
[*]then[#]. The system will emit a long beep and return to disarm state.
3.2 Arming and Disarming the System
The system has three main arming modes:
- Out Arm: Guards all around your house when everyone is out. All detectors are active. Activate by pressing the
button on the keypad or remote. - Home Arm: For safety when someone is home. Activates peripheral sensors (door, window, balcony) but bypasses indoor detectors to prevent false alarms. Activate by pressing the
button on the keypad or remote. - Disarm: Stops the alarm and puts the system in a non-warning state. Detectors will not trigger an alarm (except 24-hour zones). Disarm by inputting your password and pressing
[#]on the keypad, or pressing the
button on the remote.
3.3 Phone and SMS Functions
Setting Alarm Phone Numbers:
The system can store up to 6 phone numbers for alarm calls and 3 numbers for alarm SMS.
- In setup state, input
[51]to[56]for alarm call numbers, or[57]to[59]for SMS numbers. - Input the desired phone number and press
[#]. The system will confirm with a beep and "setting completed".
Answering Alarm Calls:
When the system calls a preset number, you can answer and interact:
- Press
[*]to read alarm information. - Press
[1]to arm and stop calling users. - Press
[2]to disarm and stop calling users. - Press
[3]to turn off the siren and monitor the scene for 30 seconds. - Press
[4]for a 30-second two-way intercom.
System Dialing Function:
In disarm status, you can use the main unit as a telephone:
- Dial the desired telephone number on the keypad.
- Press the
button to initiate the call. - Press the
button again to end the call.
3.4 Timing Settings

4. Maintenance
4.1 System Checking
Regular maintenance is crucial for ensuring the alarm system operates reliably. Perform thorough tests periodically:
- Main Unit: Check if it can arm/disarm normally, dial numbers for alarms, receive wireless signals, and if the backup battery is working.
- Detectors: Trigger wireless detectors to confirm they alarm normally. Check all detector batteries for low voltage. Verify wireless detectors send signals to the main unit.
- Frequency: Perform a thorough test on the main unit every three months. Check detectors at least monthly, or as frequently as possible.
4.2 Power Outages Alarm
The G2B/M2B system features a built-in rechargeable battery that provides continuous operation during external power supply interruptions. In case of a power outage, the system will automatically switch to battery power and send an SMS notification to your configured numbers.
5. Troubleshooting
- No Alarm Trigger: Ensure sensors are correctly coded and have working batteries. Check the defense zone programming to ensure the zone is not bypassed or set to a non-alarming mode.
- No SMS/Call Notification: Verify that the SIM card is properly inserted, has credit, and the alarm phone/SMS numbers are correctly configured. Check GSM signal strength.
- False Alarms: Ensure sensors are installed correctly and not in areas prone to false triggers (e.g., direct sunlight for PIR, loose windows for door sensors). Consider adjusting defense zone programming.
- System Unresponsive: Check power supply and backup battery. Perform a factory reset if necessary (see Section 3.1).
Important Notes:
- Do not disassemble, repair, or alter the products without permission to avoid accidents or faults.
- Avoid dropping the product on hard surfaces.
- Do not set emergency numbers (e.g., 110, 119) as alarm phone numbers without proper authorization.
