The FG318 and FG323 are LPCB-certified conventional photoelectric smoke and heat detectors designed to respond reliably across a wide spectrum of fire types. Factory tested and calibrated for high accuracy and low false alarm rates, they combine advanced detection technology with a sleek, low-profile design that suits any commercial or residential installation.

Two Detection Technologies, One Consistent Platform
The FG318 uses advanced photoelectric smoke detection technology, offering a coverage area of up to 100 m² per detector. The FG323 is a conventional heat detector covering up to 50 m². Both share the same compact form factor and dual 360° LED indicators, ensuring consistent visual alarm confirmation from any viewing angle.

Flexible Wiring Options
Available in 2-wire and 2-wire with LED variants, with a selectable N/C (normally closed) or N/O (normally open) relay output — providing the flexibility to suit a wide range of conventional fire alarm panel configurations. Detector sensitivity is programmable via the FACP.
