The GSM SMS Controller is a versatile and user-friendly device designed for remote access control, equipment management, and asset protection through SMS text messages from your mobile phone. It serves as a digital input monitoring alarm unit, capable of remotely switching machines and providing real-time alerts.
Function Description
The core function of the GSM SMS Controller is to enable remote control and monitoring of various systems and equipment. It allows users to turn devices ON/OFF remotely using SMS commands, making it ideal for applications where physical presence is inconvenient or impossible. Beyond simple switching, the controller incorporates multi-digital inputs, which, when triggered, can automatically activate a siren or switch on a light. Simultaneously, it dispatches SMS alerts to designated owners, providing immediate notification of events. This feature is particularly valuable for low-cost asset protection solutions.
Typical applications for this controller are broad and diverse, encompassing security, monitoring, and automation across various industries. It can be integrated into security alarm systems for comprehensive protection, and used for supervision and monitoring alarm systems in critical environments. For automated processes, it functions as an automatic monitoring system, ensuring smooth operation and prompt alerts in case of deviations.
In the realm of vending machines, it offers security protection, safeguarding assets and ensuring operational integrity. It's also suitable for monitoring pumping stations, tanks, and levels of oil or water, providing crucial data for resource management. Buildings and real estate benefit from its ability to monitor various parameters and provide security. Weather stations can utilize it for remote data collection and alert generation, while river monitoring and flood control systems can leverage its capabilities for early warning.
For industrial infrastructure, the controller is applicable to oil and gas pipelines for monitoring and corrosion protection, ensuring the safety and longevity of these critical assets. It supports temperature and water leakage applications, preventing potential damage and costly repairs. The device is also useful for monitoring wellheads, boats, and vehicles, offering security and tracking capabilities.
In energy management, it can be used in energy-saving and street light control systems, optimizing power consumption. Valve controls can be automated and monitored remotely, enhancing operational efficiency. Transformer stations and unmanned machine rooms can benefit from its monitoring capabilities, ensuring stable operation and alerting personnel to issues. It finds application in control room environments for centralized monitoring and in broader automation systems (M2M) for seamless machine-to-machine communication. Furthermore, it functions as a GSM access control system and a GSM gate opener, providing secure and convenient access solutions.
Usage Features
The GSM SMS Controller is designed for ease of use and configuration. It can be operated from anywhere, without distance limitations, thanks to its GSM/3G/4G capabilities. The device supports quad-band GSM GPRS modules (850/900/1800/1900Mhz), with optional 3G UMTS/HSDPA/4G modules available for broader network compatibility.
The unit is built with a 32-bit MCU and features an in-built watchdog, ensuring reliable performance. It offers two relay outputs, capable of handling significant loads (7A@125VAC, 5A@125VAC, 20A@14VDC). One relay output is dedicated for alarm linking, which can be switched on for a duration of 0-120 minutes if the controller is triggered. The other relay output can be independently controlled via SMS commands.
The controller provides 2, 4, or 8 alarm logic digital inputs, with options for Normally Closed (NC), Normally Open (NO), and End-Of-Line (EOL) configurations. It is compatible with wet contacts and includes reverse protection to prevent damage from incorrect wiring. A dedicated siren output allows direct connection to a siren, which will activate upon an alarm event.
For alert notification, the device supports three SMS alert numbers and five alarm dial telephone numbers, ensuring that critical messages reach the right personnel. Users can arm, disarm, inquire about the system status, and switch the independent output relay ON or OFF using simple SMS commands. Password protection is implemented to prevent unauthorized access and control.
Configuration and programming are made easy through a PC Configurator software, connected via a USB cable. This allows for detailed setup of parameters and loading of profiles. For mobile convenience, the controller supports Android and iOS apps, providing a user-friendly interface for operation and configuration.
The device includes an in-built rechargeable battery, which provides power lost/recover alarms, ensuring continuous operation and low maintenance. It is designed for 24x7 operation. The physical design supports both wall mounting and 35mm standard DIN rail installation, offering flexible deployment options. Its metallic cover and small dimensions (L70W88H30mm) make it compact and durable.
Maintenance Features
Maintenance of the GSM SMS Controller is straightforward. The device supports firmware upgrades via its USB port, allowing users to keep the unit updated with the latest functions and improvements. If new requirements necessitate a firmware update, the user can easily perform this process by connecting the device to a PC via USB.
The manual provides clear instructions for initializing or resetting the GSM unit to factory default settings, which is useful in case of programming errors. It also includes a comprehensive trouble-shooting guide to help users diagnose and resolve common issues, such as GSM module initialization failures, automatic restarts, false alarms, and SMS/dialing problems. This guide covers potential causes and provides actionable solutions, including checking battery voltage, signal strength, wiring, and SMS command formats.
The device is warranted to be free of defects in material and workmanship for one year, though this warranty does not cover defects or failures caused by abuse, misuse, or deviation from the operating instructions. Maintenance should only be carried out by qualified personnel to ensure proper functioning and safety. The design, including the in-built rechargeable battery, contributes to low maintenance requirements, supporting continuous operation.
