The FG-03127 series are LPCB-certified electronic sounders designed for fire alarm, security, and industrial signalling applications. Delivering up to 114 dB(A) of sound output at ultra-low current consumption, they provide powerful, reliable audible alerting in a compact, durable ABS housing. The FG-03127-BS adds a high-efficiency visual beacon for locations requiring combined audio-visual notification.

Flexible & Easy to Configure
32 selectable signalling tones via DIP switch allow the device to be configured precisely for the application. A built-in volume control offers up to -20 dB of adjustment as standard. Dual 12/24V DC operation in a single unit means no manual adjustment is needed when used across different system voltages — simplifying stock management and installation.

Straightforward Installation
Two sets of IN and OUT terminals facilitate simple loop wiring, and the compact form factor suits a wide range of mounting locations. The high-efficiency lens on the FG-03127-BS maximises visual output for enhanced coverage.
