CJB-U1 Luxury Intelligent Siren
PARZ Introduces CJB-U1 Luxury Intelligent Siren: Touchscreen & Voice-Controlled, Integrated Light & Siren Management
WENZHOU, China – PARZ, a leading supplier of public safety and emergency equipment, today launched the CJB-U1 Luxury Intelligent Siren Amplifier – a new-generation vehicle siren system that combines a tempered glass touchscreen hand controller, integrated light control, and voice recognition for hands-free operation. Designed for police, fire, ambulance, and other special service vehicles, the CJB-U1 delivers a smarter, safer, and more efficient warning solution.
One System, Full Control – Siren + Lights + Voice
Unlike traditional sirens, the CJB-U1 functions as a central command hub:
18‑button high‑sensitivity touchscreen controller with durable tempered glass, strong anti‑interference capability, and an attractive flush‑mount design.
3‑channel light control (LAMP1 / LAMP2 / LAMP3), each supporting up to 10A, allowing direct on‑off control of warning lightbars or strobes without a separate switchbox.
Built‑in voice recognition (ASR) : wake the system by saying “Hey you two”; the siren responds “Ready for action” and accepts spoken commands for all major functions – keeping the driver’s hands on the wheel.
Rich Tone Selection for Any Scenario
The CJB-U1 offers nine independent siren tones, selectable via touch or voice:
MAN (Manual), HORN1 (bass), HORN2 (high), YELP, WAIL, MECH (Mechanical), PHSR (Phaser), HI-LO, TOOL
For dual‑channel models, DUAL TONE mode mixes two tones simultaneously. On single‑channel 100W/150W versions, this key can be re‑assigned as Flash Mode for light synchronization.
Intelligent Audio & Recording Features
USB input – store and play multiple MP3 files; supports single‑loop or continuous playback
SEL – next file / track selection
REC – voice recording with up to one minute of capture; repeatable overlay and loop playback
MUTE – instant silent mode
4‑step volume memory – cycle and store preferred levels
