Installation/configuration notes
Notice
Current consumption of the connected devices and cable length can be calculated with the Safety Systems Designer (SSD).
• Country-specific standards and guidelines must be considered during planning.
• For operation of the fire detection system according to EN 54-13, it is necessary to terminate every stub and T-tap with EOL-modules.
