Trystar FastLITE Model FST

The Trystar FastLITE Model FST, 525W – 2.2kW, UL924 Emergency Lighting Inverters offer a fast-transfer (≤ 2 millisecond), high efficiency design. The FastLITE is available in wall-mount and floor-mount models. Designed for LED fixtures/drivers, as well as all other emergency lighting loads, the Model FST has an efficiency rating of up to 98.8%.  All models are provided with a “normally on” output and a “normally off/switched” output.

The Model FST meets the NFPA 101 definition of a computer-based, self-testing/self-diagnostic emergency lighting system with data-logging. Both periodic and annual tests are performed automatically, and the results are logged with a date and time stamp. Both alarm and test logs provide a history of events, and the ability to generate an NFPA-compliant report. In addition to periodic and annual testing, the Model FST performs a weekly self-diagnostic to assure reliability.

Whether fed from the AC power source or even while in battery mode, the Model FST has a peak overload capability of 1500% to accommodate inrush current from LED fixtures / drivers. An “FST Interface Application” enables it to communicate directly with a computer, laptop, or Windows tablet.

Trystar FastLITE Model FST Features

• Compatible with LED fixtures / drivers
• Available output “Surge Protection Device” (SPD) with status indicator and alarm; 40kA peak surge current rating protects LED lighting / drivers
• Up to 98.8% operating efficiency
• 90 minute battery runtime
• Optional 30, 60, and 120 minute battery runtimes
• “Normally On” output and “Normally Off / Switched” outputs
• “Normally Off” output can be energized by using an external on/off control device (e.g., wall switch or occupancy sensor). This allows the “Normally Off” output to be switched on/off when utility power is available. During utility failure and test modes (inverter on battery), this on/off control is overridden, and the “Normally Off” output is energized.
• Basic Monitor (LED indicators) or the Intellistat TS (touchscreen) Monitor, allowing access to user-programmable settings
• Weekly self-diagnostic (in addition to periodic and annual testing, per NFPA 101)
• Input breaker and (1) output circuit breaker
• Optional output distribution:
  Up to (10) unmonitored or (6) monitored breakers on 120 VAC or 277 VAC units
  Up to (3) monitored, fused switches on 347V units
  (Consult factory for specific output breaker ratings)
• Battery circuit breaker
• Low battery voltage disconnect
• Form C “General Alarm” relay contacts
• Form C “Battery Test Active” relay contacts
• USB communications port, allowing battery test and alarm logs to be viewed and electronically saved as an NFPA-compliant report
• Optional Intellistat TS network monitoring and reporting via BACnet/IP or BACnet MS/TP, Ethernet TCP/IP, MODBUS TCP, or MODBUS RS485
