The RF-JZYK-SK01 Central Siren Controller integrates a touchscreen display, numeric coding keypad, and a domestically manufactured 25 W radio. It accurately transmits nationally specified warning commands, including preliminary warning, air-raid warning, all-clear, disaster warning, and fire warning signals.The controller can issue system-wide, individual, and group commands through multimedia control software. It can also operate independently of the software, using its LCD to display transmitted commands and acknowledgment information returned by field terminals.
SYSTEM ARCHITECTURE
◆ Modular architecture comprising an anti-interference wireless digital transmission unit, wired communication unit, control unit, power supply unit, and interface unit.
◆ The wireless transmission, control, power supply, and interface modules form the basic system configuration.
CONTROL, COMMUNICATION & COMMAND FUNCTIONS
◆ Receives and executes commands from the alarm-control computer terminal and forwards acknowledgment information received from alarm controllers back to the computer terminal.
◆ Issues all configured warning commands directly from the local keypad in system-wide control mode without requiring acknowledgment, and supports forced termination of active commands.
◆ Supports remote modification of alarm-controller parameters.
◆ Synchronously transmits commands through multiple communication methods.
◆ Supports data transmission with intermediate stations while operating online.
◆ Commands alarm controllers to return status and execution acknowledgments immediately.
◆ Provides two-way real-time voice communication with alarm controllers and intermediate-station controllers.
◆ Supports voice broadcasting through connected alarm controllers.
◆ Provides network and RS-232C control interfaces.
◆ Includes reserved interfaces for emergency-equipment detection and system integration.
◆ Supports coordinated frequency adjustment; when the central station changes frequency, all terminals synchronize to the same operating frequency.
OPERATIONAL FLEXIBILITY
The controller supports both software-assisted centralized management and stand-alone local operation, enabling dependable warning activation, terminal monitoring, voice communication, and emergency-system integration even when the multimedia control platform is unavailable.
