The AT-F323 Emergency Start/Abort Station provides manual control inputs for a gas extinguishing or clean agent fire suppression panel. In an emergency, operators can break the seal, lift the protective transparent cover and press the START glass to send an emergency release command to the control panel. After the panel’s preset delay, the solenoid valve is energized and the extinguishing agent is discharged.
If personnel confirm that there is no real fire during the countdown, they can open the lower small cover and press the STOP/ABORT button. This immediately interrupts the delay and inhibits the discharge output, preventing an unwanted release and protecting cylinders, piping and protected assets.
AT-F323 is a non-addressable, multi-wire device powered from a DC 16–32 V loop, with very low operating current and LED status indication for normal/run, emergency start and emergency stop states. The unit can be mounted in a standard 86 mm recessed box or with a surface back box, making it suitable for both new installations and retrofits.
