The ANWETECH AT-F328 Gas Discharge Alarm is a two-wire visual warning device designed for gaseous fire suppression systems.
When activated by the discharge warning output of a gas extinguishing control panel, the AT-F328 provides a high-visibility flashing warning indication to alert personnel that gas discharge is imminent or in progress.
The unit features a durable iron enclosure, wall-mounted installation and a clear GAS DISCHARGE warning indication.
The AT-F328 Gas Discharge Alarm is designed to provide a clear visual warning as part of a gaseous fire suppression system.
The device connects to the designated discharge warning output of the gas extinguishing control panel through a 2-wire circuit.
When the control panel activates the discharge warning output, the AT-F328 flashes continuously while the warning signal remains active, providing a highly visible indication of the gas discharge condition.
The unit is typically installed in a clearly visible position outside the protected area or along the evacuation route, according to the approved fire suppression system design.
With its compact 302 × 98 × 43 mm iron enclosure, low current consumption and wall-mounted construction, the AT-F328 provides a practical gas discharge warning solution for fixed gaseous fire suppression installations.

The AT-F328 connects to the discharge warning output of a gas extinguishing control panel.
The connection is made through a 2-wire warning circuit.
When the gas extinguishing control panel activates its discharge warning output, the AT-F328 is activated and flashes continuously while the warning output remains active.
Basic Connection Principle:
Gas Extinguishing Control Panel → Discharge Warning Output → 2-Wire Circuit → AT-F328 Gas Discharge Alarm
Installation and wiring should follow the approved project wiring diagram, the gas extinguishing control panel documentation and the terminal markings on the supplied AT-F328.
The AT-F328 should be installed in a clearly visible position where the gas discharge warning can be easily observed.
Recommended installation locations include:
The warning indication should remain unobstructed and clearly visible from the normal approach direction.
Install the unit in a dry location and avoid direct water exposure.
For wiring, use BV cable with conductor cross-sectional area ≥1.5 mm², or cable specified by the approved project design and applicable local requirements.
The AT-F328 is intended for use as a visual gas discharge warning device in:
Actual installation shall follow the approved fire protection system design.
