Luz-Sirene (also known as Luz Berlin or simply Luz/Lutz) was founded by an Ernst Beissel[1]—it was in operation from 1927 to 1977[1] and produced electromechanical warning sirens in Göppingen, BW.[1] It is speculated the company had some relation to Elektror, as Luz-Sirene offered sirens similar in construction to Elektror products; it is possible there was an exchange of technical ideas and designs between both companies for an unknown period of time. Very little is known about Luz-Sirene and few of their products remain today.

Type K
The Type K (German: Typ K) is a small omnidirectional electromechanical siren and is identical to Elektror's Type S2 (German: Typ S2). The Type K utilizes a 9-port rotor and stator and is driven by a 3 ph 0.7 kW (1 hp) 400 V motor below the stator which spins the rotor at around 2890 rpm. A metal mesh screen attached to a circular assembly bolted to the top of the rotor prevents debris from entering the rotor or injury from misuse of the siren. A conical rain shield is held above the stator with support struts, as well as a slightly larger in diameter louver which is bolted to the top of the stator which propagates the siren's sound downwards and outwards. A cylindrical base below the motor allows the siren to be bolted to a flat surface. Little else is known about the siren, due to a lack of units and no documentation known to exist. The siren weighs around 22 kg (48.5 lbs), slightly more than the Type S2 due to heavier materials being used for the construction of the Type K.
Type L
The Type L (German: Typ L) is a small omnidirectional siren modelled after the E57 with minor differences. Like the E57, the Type L is a 9-port siren, with a 3 ph 50 Hz 220 V 1.4 kW (1.8 hp) electric motor underneath the stator that drives the rotor at around 2800 rpm. A metal mesh screen is wrapped around the stator ports to prevent debris from entering the siren or injury from misuse. A flange below the stator directs the siren's sound downwards and outwards and has a rotation arrow cast on, which displays the correct way the rotor is supposed to spin. The motor is enclosed in a cylindrical casing which is bolted to a triangular base with 3 holes in each corner allows the Type L to be bolted to a flat surface. A protective dome, which is smaller and less pronounced compared to the E57, both shielded the siren from the elements and propagated the siren's output downwards. The Type L is smaller in size (around 39 cm (15.3 in) in diameter compared to the 50 cm (19.6 in) E57) and weight (around 35 kg (77.1 lbs) compared to the ~60 kg (132.2 lbs) E57). Little else is known about the Type L, and very few of these sirens exist today.
Type M
The Type M (German: Typ M) is a small omnidirectional electromechanical siren. The Type M utilizes a 9-port rotor and stator and is driven by a tiny 60 V motor below the stator which spins the rotor at around 2890 rpm. A triangular or helmet-like dome is held above the stator with support struts, which shields the siren from the elements and propagates the siren's sound downwards and outwards. A cylindrical base below the motor allows the siren to be bolted to a flat surface. Little else is known about the Type M, and very few of these sirens exist today.
Type P
The Type P (German: Typ P), also known as the Auto-Siren (German: Auto-Sirene), is a small electromechanical vehicular siren, similar in appearance to the Elektror FS 00. It is 7-port and driven by a small 12 V motor encased in a bullet shaped two-piece housing. A grille with 4 cowls covers the front of the siren, and a metal mesh screen wraps around the stator ports, helping prevent debris from entering the siren or injury from misuse. The siren is attached to a swivel mount which allows it to be positioned a certain angle. It has a rhombus shaped base with 2 holes on both edges, allowing for the siren to be bolted to a flat surface. Little else is known about the Type P, and very few of these sirens exist today.
Type S
The Type S (German: Typ S) is a small omnidirectional electromechanical siren. The Type S utilizes a 9-port rotor and stator and is driven by a tiny 60 V motor below the stator which spins the rotor at around 2890 rpm. A triangular or helmet-like dome is held above the stator with support struts, which shields the siren from the elements and propagates the siren's sound downwards and outwards. A cylindrical base below the motor allows the siren to be bolted to a flat surface. Little else is known about the Type M, and very few of these sirens exist today.
