The Model LK-JDWPK is a sub-series of electromechanical omnidirectional sirens in the Large Electric Motor Siren series produced by Thành Công Vietnam Co., Ltd., a Hanoi-based rebadger of Lion King. Interestingly, these sirens seem to be a creation of Thành Công as opposed to Lion King themselves, as they are not sold on any of Lion King's websites. They are intended to be used as flood/dam sirens and can be found in several places in Vietnam.
Design
Model LK-JDW480PK
The Model LK-JDW480PK is the single-rotor option in the series and seems to be based upon the LK-JDW480, specifically the 380 V model. The siren consists of a standard LK-JDW480, a 10-port siren powered by a 380 V AC 50/60 Hz 2.2 kW (3 hp) motor. A large, thin rain shield is bolted above the stator, which protects the siren from the elements. A small eyebolt is located above the rain shield. The rain shield on the Model LK-JDW480PK is slightly different compared to the one on the Model LK-JDW480, being triangular as opposed to rounded. A ring with 10 holes, which 10 horns connect to, are fitted around the stator. On some units, the horns are angled to the right, in a similar manner to various French sirens, of which Thành Công likely took inspiration from. The motor is protected by a large cylindrical enclosure below the rotor and stator. The siren is held up by a Federal-esque angle iron mount.
Model LK-JDW245PK
The Model LK-JDW245PK is the dual-rotor option in the series and seems to be based upon the LK-JDW245. The siren consists of a standard LK-JDW245, a 6/6-port siren powered by a 220 V AC 50/60 Hz 0.75 kW (1 hp) motor, which is flipped vertically and lacks a stand. A ring with 10 holes, which 10 horns connect to, are fitted around each stator, with the siren having 20 in total. Interestingly, the number of horns does not match the number of ports on a LK-JDW245, similarly to a Darley STH-10. The motor is protected by a large cylindrical enclosure. 4 legs mounted to the top stator support a large rain shield, which protects the siren from the elements. This is all mounted to a large cylindrical stand below the bottom stator, which rests upon a circular base with 6 holes around the edge, which allow the siren to be mounted to a flat surface. This stand also functions as an intake, with 4 rectangular openings cut in to it, allowing air to reach the bottom rotor. The stand often varies in width and height between units, as evidenced by the photos of the siren provided by Thành Công's website. The siren reaches 135 dB at 1 m (3 ft).
