The 500 series of Personal Locator Beacons or Survival Emergency Locator Transmitters offers a wide range of options to suit any requirement. The 500 series of Personal Locator Beacons has been chosen by a wide customer base, including armed forces, commercial airlines, off-shore helicopter operators, life raft manufacturers and ejection seat manufacturers.
For all the 500 series Personal Locator Beacons, Techtest has obtained full certification to aircraft standards so these products should not be confused with inferior quality beacons intended for hobby use.
The 500-1 Personal Locator Beacon is a compact light-weight unit operating on 121.5 MHz and 243 MHz and has been favoured by customers requiring a small beacon for many years.
The 500-12 Personal Locator Beacon is designed to work with the COSPAS-SARSAT search and rescue satellite system and features 406 MHz as well as 121.5 MHz and 243 MHz distress signals. It also incorporates a speech function which allows survivors to have two way voice communication with a rescue craft. In addition to the normal aircraft approvals the 500-12 also has full Boeing and Airbus approvals making it the natural choice for commercial airline operators due to its compact size and low weight. The 500-27 shares all the functionality of the 500-12 but also incorporates embedded GPS to minimize location time in the event of an emergency.
The latest 500-27-07 PLB (above right) utilizes all the proven electronics of its predecessors but updates the casing design to give a modern stylish appearance without losing the rugged and durable qualities associated with Techtest SAR products.
The new 500-32 PLB (above left) offers similar features to the 500-27-07 but in a significantly smaller package (35% reduction in volume). This has been achieved by using state-of-the-art battery technology and optimised electronics.
After rigorous testing the 500-32 series of ELT(s) or PLB has recently been awarded a COSPAS SARSAT type approval (Certificate No. 223).
500-30, 406 MHz Ejection Seat Compatible PLB
The 500-30 is the latest member of the highly successful Techtest PLB range offering 406MHZ transmission and Guard frequency transmission combined with embedded GPS to provide positional accuracy of 100m.
With both manual and automatic activation capability the beacon offers maximum flexibility across a fleet of aircraft. Providing interface solutions for inclusion in PSPs within ejection seats such as ACES II/III and in combination with parachute activation mechanisms such as the BA22. Once activated upon ejection the PLB will transmit SAR frequency signals via remote antennas allowing rapid recovery.
Once on the ground aircrew can continue to transit using remote or integrated dual frequency antennas including GPS providing portable functionality and the ability to control beacon transmission according to circumstance. With 5 year battery life, 48 hours transmission on 121.5MHz and 24hours on 406MHz at -20 Â°C the 500-30 meets COSPAS SARSAT, ED-62A, STANAG 7007 and MIL-STD 810F specifications.
