PHARODECK™ TD/PM Circle & H System

The PHARODECK Touch Down and Perimeter Marking (TDPM) System provides a complete Zone 1 and Zone 2 system solution to CAA-UK CAP 437 and ICAO Annex 14 requirements.

PMAPI's PHARODECK TDPM unique design permits an extremely fast and efficient installation time as interconnection cables are incorporated within the pre-assembled deck plates.

The housing of the cables within the deck plates also gives maximum mechanical protection and minimises trip hazard.

Modular Design

The modular design allows for accelerated installation time due to the interconnection of the cables being incorporated into preassembled deck plates.

Pharos Marine Automatic Power’s TD/PM segment design is deliberately engineered such that where an element/segment failure is encountered, a replacement segment can be readily fitted by means of accessing the internal junction box to remove the connections then removing the segment from the mounting plate and replacing the segment/sub-section.

The system is designed to provide our customers with a cost effective offering that can be easily maintained as a long term solution to Helideck lighting.
