• Verify that the control cabinet can support the 8kg unit weight and adequate cooling.

Professional FAQ

• How does the CP451 redundancy function in this unit?
• Two CP451 modules run in parallel; if the active unit fails, the standby takes over in milliseconds.
• What is the recharge requirement for the memory battery?
• The battery requires a minimum of 48 hours of continuous power to provide the full 72-hour backup.
• Can I expand the node capacity beyond 3 units?
• Yes, while LFS1500 supports 3 nodes, adding the LFS1550 package allows expansion up to 14 nodes.
• What happens to the status contact during an FCU failure?
• The AFV10D-S41201 status contact (NC) will open, triggering your external alarm system.
• Is this unit compatible with ER bus nodes?
• Yes, by installing the EB401 Interface Master Module in the appropriate odd-numbered slots.
