The SECUMAR Window ALPHA 275 lifejacket/lifevest is more compact and comfortable than ever before. The new buoyancy chamber design makes the lifejacket about 10 cm shorter.

When the lifejacket is inflated the back strap adjusts automatically and ensures an optimal fit of the lifejacket/lifevest.

Lifejackets need a service too

Where the safety of peoples’ lives is concerned, regular inspection of the equipment concerned is absolutely essential. This also applies to lifejackets. Natural aging process can influence the properties of the material and also the functioning of the automatic inflator system is not immune to possible damage (among other things operational errors). In other words: the life of a lifejacket must be limited. The corresponding time frame has been set at 10 years, a decision borne authoritatively by the members of the German Association for Sea Rescue Equipment (FSR), and which complies with the law of safety and product liability.

A prerequisite for this lifetime is an inspection of the lifejacket by an authorized servicing station or the manufacturer at least every two years.

Safety as a visible sign

Regular inspection is documented by the FSR-Service-Sticker, which, similarly to a car’s MOT sticker, signalizes the month and year of the next service due.


The regular system check by the expert comprises testing the buoyancy chamber for air leaks as well as a scrutinizing check of the fully automatic inflation system. Moreover, within the framework of this SERVICE we can offer:

  • Repair
    Removal of any defects discovered in the course of the inspection as well as replacement of the complete protective cover or buoyancy chamber.
  • Conversion / Optional extras
    Converting from manual release to automatic inflation, adding a spray hood, installation of an emergency light and further signalling accessories.

Receipt of the new FSR-Service-Sticker confirms, so to speak, the correct functioning of the rescue equipment and always reminds you of the Date of the next inspection, the sticker being clearly visible from the outside.
