The SARBE 7 Personal Locator Beacon is a compact lightweight radio beacon designed for use as a military or civil survival aid.

Activated by removal of an operating pin - either manually or automatically by such functions as liferaft inflation or ejector seat operation, the unit transmits an internationally recognised swept-tone radio distress signal on both UHF and VHF distress frequencies.

Simultaneous, omnidirectional transmission of both 121.5 MHz and 243 MHz signals then continues automatically for a minimum of 48 hours. This enables maximum detection opportunity by the orbiting COSPAS/SARSAT satellite system and provides scene of search homing ranges of 50 nautical miles with receiving aircraft at 10,000 ft.

Built in test (BITE) facilities allows the user to check battery condition, circuit integrity and RF output to the antenna via a 'GO' green LED confidence indicator. Operated by lifting a 'Test Lever' mounted on the side of the unit, SARBE 7 can be quickly cleared before the commencement of a flight or at regular intervals.

The SARBE 7 is waterproof to a depth of 10m (30ft) and the battery has an unsed shelf life of 5 years when stored in continuous temperate conditions.

Fully approved by the CAA (Approval No. WR01012), FAA to TSO C91a and meeting NATO STANAG 3281, 5th edition, the unit is COSPAS/SARSAT compatible.
