The F8 module adds 8 FAI-controlled voltage outputs to a FlexPower power supply and is typically supplied as part of a system or purchased as an expansion piece to an existing system.

Each module provides 8 protected outputs, each output programmable to enable voltage on activation of the fire alarm interface (FAI), disable voltage on FAI or provide a constant output voltage.

Each output is also programmable to either of the two voltages available when used in a FlexPower dual voltage power system. Red F8 boards are GEN II which adds add OutSmart dual color LEDs to visually indicate voltage levels by Buss input (Green for 12V, Blue for 24V).

The F8 is typically used for controlling door holders or door locks in fail-safe, fail-secure or egress modes.
