FTW 175 SAT Satellite Monitor

The FTW 175 SAT is the satellite-linked variant of Flash Technology's FTW 175 monitoring family, designed for obstruction lighting structures where cellular coverage is absent, unreliable, or not permitted. It uses Inmarsat's IsatData Pro (IDP) network — a two-way satellite data service with published 99.9% network availability — to deliver 24-hour positive communication confirmation and alarm notifications to Flash Technology's web portal from essentially any location across North America.

The unit provides the same core compliance function as the FTW 175 Eagle: satisfying FCC CFR 17.47's 24-hour reporting requirement without a site visit, and supporting FCC quarterly inspection waiver eligibility when paired with Eagle-interface-compatible Flash lighting equipment. Three dry-contact monitoring inputs cover the lighting circuit and auxiliary channels. An integrated SkyWave satellite terminal with environmentally sealed housing requires no antenna aiming, simplifying installation on towers where precise antenna alignment would be operationally difficult.

The operating temperature range of the IDP-6xx series module (-40°C to +85°C) covers Arctic and desert extremes, making this suitable for geographically isolated or climatically demanding sites — offshore platforms, remote desert communications towers, or high-altitude relay stations in the GCC region where cellular infrastructure does not reach. Battery backup of 4+ hours (two hours longer than the cellular Eagle variant) reflects the expectation of extended mains outages at off-grid locations. A 2-year warranty applies. The FTW 175 SAT costs more to operate than the cellular Eagle due to Inmarsat airtime, so it is reserved for genuinely remote applications where cellular is not viable.
