Motor siren replacement
The motorized siren was used throughout the country during the Cold War. Originally intended to warn the population, the standard siren, E 57 for short, was decommissioned in many places in 1957 after the immediate threat. Nowadays, however, it is still used by many municipalities and communities to alert fire departments.
These motorized sirens are usually overhauled, but are still state of the art from the 1950s.
We recommend replacing old motorized sirens with more economical and efficient electronic sirens from SONNENBURG!
MOTOR SIREN E57
High Maintenance: The mechanical components and motor require regular maintenance, as bearings, grease and many small mechanical wear and tear. This results in high maintenance costs.
High power requirements: Motorized sirens rely on a continuous power supply and consume more energy than their electronic counterparts.
No alternative power supply: It will not will not work in the event of a power failure.
Limited alarm options: A motorized siren only has one signal tone with a limited number of alarms. The technology cannot be extended and voice announcements are not possible.
Negative effect on roof construction: If an imbalance occurs on the rotating parts, this causes a strong vibration that can have a negative effect on the roof structure.
Less efficient sound propagation: Directional sounding is not possible and is less effective than with an electronic siren
ELECTRONIC SIREN
Less maintenance: As electronic sirens have no moving parts, they require less maintenance and are more reliable over longer periods of time.
Energy efficient: They generally consume less power than motorized sirens as they use more efficient amplifier technologies and can be backed up by batteries.
Independence from the power grid: Electronic sirens can be powered by batteries, which means they can work even in the event of a power failure.
Variety of alarm signals: Electronic sirens can produce a greater variety of alarm signals, allowing for more sophisticated warning of different hazards.
Environmentally friendly: If desired, our sirens can be operated autonomously using solar cells.
Flexible expandability: Modern electronic sirens can be easily adapted to new requirements and expanded with additional functions.
