Description
The SLB 406 (Survivor Locator Beacon) is a Type S (Survival) Emergency Locator
Transmitter that provides world-wide alerting in emergency situations via a network of
satellites of the Cospas-Sarsat distress alerting system. This system enables the location,
nationality, unit serial number, and user specific registration data of the personal locator
beacon to be immediately identified with the receipt of the alert.
The SLB 406 was developed to meet demanding environmental standards for individual’s
onboard aircraft, on land and at sea. The beacon is made of tough poly-carbonate
plastic, and is designed to withstand the rigors of severe outdoor use. The flip face
cover (see Figure 4) protects the buttons and indicators against damage and inadvertent
activation. It is fully waterproof to 10m, operable over the -20°C to +55°C temperature
range. This ensures that should a survivor need help, the message will get through.
The SLB 406 user interface is intuitive and easy to use, no matter the condition of the
survivor. The SLB 406 can be used equally well with either the right or left hand, with
buttons large enough to be operated while wearing gloves. Activating the beacon is
simple and can be done with one hand, or can be activated automatically upon life vest
inflation. For manual activation, the survivor simply flips open the face cover and
presses the activate button, which immediately activates the beacon. Visual indications
of beacon activation is provided. The beacon can be switched off by the rescue crew
after the survivors have been rescued or by the survivors if multiple beacons are active.
A beacon that has been turned off can be reactivated simply by pressing the activate
button. The safety lanyard can be attached to the user’s equipment to ensure that the
beacon is not lost or otherwise separated from the person in distress.
Examples of the information that can be contained in that message are shown below:

Serial Number of the transmitter or Aircraft ID (24-Bit Address or Tail Number)

Country Code

Cospas/Sarsat ID Code (Serialized Only)
The 406.028 MHz transmitter with the supplied battery will operate for 24 hours, and
then shut down automatically. The 121.5 MHz transmitter will continue to operate until
the unit has exhausted the battery power which will be greater than 50 hours.
