The F8 module adds 8 Fire Alarm Interface (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 FAI, disable voltage on FAI or provide a constant output voltage. Each output is also programmable to either of the voltages available when used in a FlexPower dual-voltage power system. R8 incorporates OutSmart Color changing LEDs which visually indicate the selected voltage output setting (12V/Green, 24V/Blue). The F8 is typically used for controlling door holders or door locks in fail-safe, fail-secure or egress modes.
