The Explosion Proof Sirens series is a series of explosion proof electromechanical sirens produced by Taizhou Lion King Signal, or simply Lion King, based in the People's Republic of China. The series was first introduced sometime in the mid-to-late 2000s and has been produced ever since.

Design

Model LK-JDW245B

The Model LK-JDW245B is the explosion proof variant of the Model LK-JDW245, and the midrange option in the Explosion Proof Sirens lineup. The Model LK-JDW345B consists of a 7-port rotor and stator, driven by a dual-ended 0.75 kW (1 hp), 50/60 Hz, 380 V AC explosion proof motor. Mesh screens are located around and in front of the stator to prevent injury from misuse of the siren, as it is small enough to be handheld. The siren is mounted upon a small rectangular base (which differs from the one used on the original siren), with 4 holes in each corner, allowing for the siren to be mounted. The siren reaches 130 dB @ 1 m (3 ft), 7 dB louder than the Model LK-JDW245.

Model LK-JDW400B

The Model LK-JDW400B is the explosion proof variant of the Model LK-JDW400, and the midrange option in the Explosion Proof Sirens lineup. The Model LK-JDW400B consists of a 10-port rotor and stator (as opposed to the original siren's 2) driven by a single-ended 3 kW (4 hp), 50/60 Hz, 380, 400, or 440 V AC explosion proof motor. 10 beams are in front of the stators, with each connecting to a large cylindrical center, likely to make it harder for birds to nest into the rotor. A grille is also present behind the beams. The siren is mounted upon a small rectangular base, with 4 holes in each corner, allowing for the siren to be mounted. The siren reaches 128 dB @ 1 m (3 ft).

Model LK-JDW450B

The Model LK-JDW450B is the explosion proof variant of the Model LK-JDW450, and the largest option in the Explosion Proof Sirens lineup. The Model LK-JDW450B consists of a pair of 10-port rotors and stators, each driven by a dual-ended 7.5 kW (10 hp), 50/60 Hz, 380, 400, or 440 V AC 3 ph explosion proof motor. 10 beams are in front of each of the stators, with each connecting to a large cylindrical center, likely to make it harder for birds to nest into the rotors. A grille is also present behind the beams. The siren is mounted upon a small rectangular base, with 4 holes in each corner, allowing for the siren to be mounted. The siren reaches 133 dB @ 1 m (3 ft).
