The FG901 SOUND series are robust, addressable sirens engineered for reliable fire alarm notification in demanding environments. Built from glossy red ABS with an IP65 ingress protection rating, they are equally suited to indoor and challenging installations. Each unit features an integrated short-circuit isolator, guaranteeing uninterrupted loop communication even in the event of a fault.

Three Models for Every Need

• FG901SI_AP — Addressed siren (audible only), EN54-3 & EN54-17
• FG901SFI_AP — Addressed siren with flashing light, EN54-3 & EN54-17
• FG901SFI23_AP — Addressed siren with flashing light, EN54-3, EN54-17 & EN54-23 (visual alarm coverage W-2,4-5)

Powerful Performance
All three models deliver 80–100 dB sound output at a siren voltage of 24 VDC, with standby consumption of just 120 µA — making them highly efficient for large loop deployments.

Simple Installation
Addressing is handled via programmer or auto addressing — no DIP or rotary switches required. Compatible with “T” connection topologies. Deep extractable terminal blocks accommodate cables up to 2.5mm², and PG7 cable glands ensure the IP65 rating is maintained throughout.
