Import Electromechanical Siren Lk-Jdw450 — Buy in Bulk from Supplier in China

The LK-JDW450 electromechanical siren is a 120 dB audible alert device designed for industrial, security, and emergency response use. It operates on multi-voltage inputs, supporting standard AC ranges from 110V to 240V, and draws less than 5A at peak output. The unit features a sealed aluminum housing with an IP54 rating for dust and splash resistance, ensuring durability in outdoor or high-humidity environments. Its internal mechanism uses a rotating cam and striker system to generate consistent, high-decibel tones without electronic amplification.

The siren produces a single, piercing tone at 120 dB at one meter, with a frequency range of 1.8 kHz to 2.2 kHz, optimized for human audibility in noisy settings. The motor is rated for continuous duty cycles up to 30 minutes, followed by a mandatory 15-minute cooldown to prevent overheating. Internal components are shielded against voltage spikes and reverse polarity, making it compatible with standard vehicle and fixed-installation power systems. No external amplifier or control box is required for basic operation.

This siren is commonly purchased by municipal emergency services, construction site managers, and industrial safety teams for alarm activation in fire, intrusion, or evacuation scenarios. Buyers typically order in quantities of 5 to 50 units, with standard packaging in foam-lined cardboard boxes. Trade terms are typically FOB from Shanghai or Ningbo port, with payment via T/T. Lead time is 15 to 25 days after order confirmation, and custom mounting brackets are available on request.
