5.4. Wiring and Bus Connection
Connect the CT-Bus GSM Mini to the alarm control panel's bus terminals according to the wiring diagram provided with your specific alarm system and the CT-Bus GSM Mini. Typically, this involves connecting data lines (e.g., DATA+, DATA-) and power lines (e.g., +12V, GND).
Important: Refer to the specific wiring instructions for your alarm control panel model to ensure correct polarity and connection. Incorrect wiring can damage both devices.
5.5. Initial Power-Up and Configuration
- After all connections are secure, apply power to the alarm control panel. The CT-Bus GSM Mini will power on.
- Observe the status LEDs on the device. A blinking LED typically indicates searching for GSM network, while a solid LED indicates successful connection.
- Refer to your alarm control panel's programming manual for instructions on how to recognize and configure the CT-Bus GSM Mini on the system bus. This usually involves assigning an address or enabling the GSM module.
- Program the desired telephone numbers for voice calls and SMS alerts through the alarm control panel's interface.
6. Operating Instructions
6.1. Alarm Event Communication
When an alarm event occurs (e.g., intrusion, fire, panic), the alarm control panel will trigger the CT-Bus GSM Mini to initiate communication. The device will:
- Send pre-programmed SMS messages to designated recipients.
- Initiate voice calls to designated recipients, playing a pre-recorded message or allowing two-way communication if supported by the alarm panel.
6.2. Remote Control via GSM
The CT-Bus GSM Mini allows for remote control of certain alarm system functions (e.g., arming/disarming, checking status) via SMS commands or specific call sequences from authorized phone numbers. Refer to your alarm control panel's manual for the specific commands and procedures.
Note: Only authorized phone numbers programmed into the system will be able to send commands or receive alerts.
