AUTRONICA
BF-502/N
INERGEN RELEASE POINT / MANUAL CALL POINT
IP66 TA = 70°C
EEX NL IIB T4
03ATEX217X EX II 3G
The Autronica BF-502/N is a manual call point designed for use within Inergen gas fire suppression systems aboard marine vessels. Functioning as a manual release trigger, it allows crew members to initiate or abort a suppression sequence at the protected space. As part of a ship’s fire alarm and gas release network, this device plays a critical role in ensuring that fixed firefighting systems can be activated under direct human control — a key requirement in regulated marine fire safety installations. Its robust IP66 enclosure rating and ATEX certification make it suitable for demanding shipboard environments.
Key Features
✓ Designed as a manual call point for Inergen gas suppression release, enabling direct crew-initiated control of fixed firefighting systems.
✓ IP66 ingress protection rating with a maximum ambient temperature rating of TA = 70°C; ATEX certified to 03ATEX217X, classified EX II 3G with EEX NL IIB T4 — suitable for use in potentially explosive atmospheres.
✓ Compatible with Autronica fire detection and gas suppression control systems; subject to confirmation for specific panel or controller compatibility depending on vessel configuration.
✓ Rated for installation in protected machinery spaces, engine rooms, or other hazardous areas where Inergen suppression systems are fitted, in compliance with SOLAS fire safety requirements for fixed gas systems.
✓ Direct replacement component for Autronica-based fire suppression networks; sourcing a like-for-like part supports system integrity and simplifies service documentation during surveys.
Marine Applications
✓ Engine rooms and machinery spaces aboard commercial vessels where Inergen total flooding suppression systems are installed.
✓ Pump rooms, compressor spaces, and other enclosed hazardous areas on tankers and offshore support vessels requiring ATEX-rated fire detection hardware.
✓ Fixed gas suppression control stations on cargo vessels, bulk carriers, and container ships subject to SOLAS Chapter II-2 fire protection requirements.
✓ Offshore platforms and FPSOs where Autronica fire alarm and suppression systems are in service and manual override capability is required.
✓ Naval auxiliaries and specialist vessels operating Autronica-integrated fire safety architectures requiring certified manual release devices.
