FastLITE Model FST
(525W to 2.2kW)
Description:
Emergency lighting inverter with fast-transfer, high efficiency design.
The FastLITE Model FST is a fast-transfer (≤ 2 millisecond transfer time) emergency lighting inverter offered in wall-mount and floor-mount models, and has an efficiency rating of up to 98.8%! It is designed for LED fixtures / drivers, as well as all other emergency lighting loads. 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.
Meeting the NFPA 101 and NFPA 111 standards, the Model FST is considered “Life Safety Equipment”. It is UL 924 listed as “Emergency Lighting Equipment”, providing the required 90 minutes of emergency backup power. Other runtimes up to 120 minutes are available. It is also C-UL listed to CSA C22.2 No. 141-15 with 30, 60, or 90 minutes.
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 the Model FST to communicate directly with a computer, laptop, or Windows tablet. Customers can download this FREE interface program and interactive PDF user’s manual.
Single Phase Sizes: 525W, 750W, 1.1kW, 1.44kW, 1.5kW, 1.7kW, 2kW, 2.2kW

- 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
- Nominal Input Voltage: 120V or 277V or 347V, 1 phase, 60 Hz
- Input Operating Voltage Range: Programmable ± 10% or +10%, -15% (without battery usage)
