Modern security and fire alarm systems frequently utilize radio channel technology to exchange information over frequencies such as 433 MHz or 868 MHz. These systems, which do not require additional licensing for properly certified equipment, come in various configurations for different applications. They are typically divided into two main groups:
1. System Types by Application
-
Object-Based Systems:
These wireless systems operate within a single facility—such as a home, office, or retail store—linking sensors directly with local control devices (PCP or similar units). -
Centralized (Control Center) Systems:
These systems relay information between a receiver/transmitter installed on the protected site and a centralized monitoring station (PSC). This setup is ideal for properties requiring oversight from a central control center.
2. Distinctions from GSM Systems
While both radio channel and GSM alarm systems use radio frequencies, they differ in their coding and data transmission methods. Radio channel equipment is purpose-built for alarm applications, ensuring robust performance within its designated operational environment. In contrast, GSM systems incorporate cellular network standards and are typically used for broader communication, particularly when remote monitoring is desired.
3. Radio Channel Security Alarm Systems
Popular among manufacturers, wireless security systems leverage a wide range of sensor types including:
- Acoustic Sensors: Detect sounds such as glass breakage.
- Magnetic Contacts: Monitor the opening of doors and windows.
- Infrared Sensors: Sense motion via changes in infrared radiation.
Leading brands in this field include:
- Teko’s "Astra RI-M" and "Astra-Zitadel" Series: Renowned for their comprehensive product ranges.
- Bolid: Offers a more streamlined lineup, focusing on magnetic contacts and opto-electronic sensors.
- Strelets (Argus Spektr): Although less varied in sensor types, they are recognized for their reliable performance.
These systems can be further enhanced with accessories such as repeaters, signal extenders, and integrated control panels, allowing for flexible, scalable security solutions.
4. Radio Channel Fire Alarm Systems
For fire protection, radio channel systems are designed with specialized detectors including:
- Point-Type Smoke Detectors
- Linear Detectors
- Heat Detectors
- Manual Call Points
These devices work in unison to provide comprehensive fire detection and can also support radio-based fire alarm notification systems. Manufacturers like Strelets and Bolid offer balanced product lines that meet stringent fire safety regulations. Key requirements—such as built-in secondary batteries and continuous functionality tests—ensure these systems comply with strict fire safety standards.
5. Radio Channel Emergency (Alert) Systems
For mobile applications—such as cash-in-transit vehicles or valuables during transport—portable emergency alert devices are essential. These typically include wearable panic buttons or keychain transmitters that communicate via radio channels with a central receiver.
Key Considerations:
- Transmission Range: Specified under ideal line-of-sight conditions, though actual performance may vary in urban environments with obstacles like concrete or steel.
- Battery Life: Maintaining reliable power is critical; low battery conditions may compromise signal transmission.
- Additional Features: Some devices feature tilt sensors that trigger alerts if the device is moved beyond a preset angle, although this may increase the risk of false alarms if not properly configured.
Final Thoughts
Radio channel alarm systems—whether deployed for security, fire protection, or emergency alerting—offer a reliable, dedicated method for transmitting critical information. By utilizing frequency ranges such as 433 MHz or 868 MHz, these systems provide robust performance in both object-based installations and centralized monitoring environments.
