The RF-JDSK-SK01 Electronic Siren Controller features an LCD display and a numeric coding keypad. Operators can assign device identification codes directly from the membrane keypad, transmit acknowledgment signals to the host system, and view control status and command information on the display.
CORE CAPABILITIES
◆ Controls electronic and electromechanical sirens and supports more than five alarm signal types.
◆ Executes each alarm signal according to a preset program, displays a countdown, and stops automatically when the sequence is complete.
◆ Supports immediate termination of an active alarm by remote command or manual operation.
◆ Receives commands from central stations, intermediate stations, relay stations, and remote-control terminals.
CONTROL, COMMUNICATION & DIAGNOSTIC FUNCTIONS
◆ Supports manual initiation and termination of all configured alarm signals from the local keypad.
◆ Returns the execution results of alarm and test commands to the central station immediately.
◆ Provides terminal-to-central-station remote acknowledgment and status-return functions.
◆ Receives alarm activation, cancellation, and test commands from central and intermediate stations and controls the siren accordingly.
◆ Supports two-way real-time voice communication and voice broadcasting.
◆ Allows remote switching of the siren host power supply.
◆ Allows remote activation of internal and external loudspeakers.
◆ Includes password protection to prevent unauthorized operation.
◆ Provides built-in self-test functions and generates fault alarms when a major internal unit fails.
◆ Maintains normal reception under 0 dB co-channel interference, even when the interfering signal has the same strength as the desired signal.
◆ At channel data rates of 600 bps, 300 bps, and 150 bps, receiver sensitivity is more than 10 dB better than that of a standard FM radio.
OPERATIONAL RELIABILITY
The controller combines remote command reception, local manual operation, immediate result feedback, self-diagnostics, and interference resistance to support reliable siren activation and status monitoring across centralized warning networks.
