Flash Technology’s Vanguard LED obstruction lighting system has been protecting towers from air traffic for nearly 5 years. We have continuously improved our product and today, the Vanguard II version is the industry standard for tower lighting quality, performance, and durability.
In the spirit of continuous improvement, we’ve continued to seek feedback from our customers so that we can improve product robustness and meet your needs. As a result of your feedback, we’re excited to announce the new FTS 370 Vanguard Medium tower lighting series which will begin shipping in September 2017.
As a result of customer feedback, Flash Technology announces the new FTS 370 Vanguard Medium tower lighting series which has begun shipping.
The input power terminal block has been upgraded with a double-pole breaker switch. This switch improves user protection and safety by tripping both legs of the circuit during an incoming voltage surge, eliminating the chance of working on a “hot” neutral. Fuse replacement costs are also removed.
The PHD516 photodiode, which features a metal condulet fitting for improved harsh environment resistance, has replaced the PHD512 that was previously used in the unit. Moisture protection has been enhanced by potting the fitting interior. Additionally, RF noise resistance and induced surge protection for the controller have been improved through incorporation of a shielded cable. To accommodate the drain wire of the shielded cable, a third position has been added to the connector on Rev B of the surge board (F2420600 AC, F2420601 DC) where the PHD is terminated.

Similar to the PHD516, the cable used to connect each marker to the marker interface enclosure is now shielded. The drain wire for the cable will be connected to the EARTH connection for each marker channel on the marker board (F2422000).
The FCC recommends that radiator equipment is separated by a distance of 10 ft from the marker or flashhead equipment to ensure that interference levels are acceptable. A buffer zone of this size is not always available on a tower and could result in interference to the RF transmitters.
The new FTS 370 Vanguard Medium series features a series of improvements to the flashhead core board, surge board and the marker interface board to lessen the likelihood of interference with other equipment on the tower. The diagram below shows how frequencies that approached the interference limit have been truncated in the new Vanguard Medium series.
