PRODUCT DESCRIPTION of Siemens 500-033090

The Siemens 500-033090 DLC Device Loop Card is a high-quality fire alarm system expansion module designed to interface intelligent fire safety field devices with advanced control panels. It is a key component in Siemens fire protection systems such as FireFinder XLS, FireFinder XLSV, and Desigo Modular/Cerberus PRO Modular platforms.

This device loop card enables connection and monitoring of fire and safety devices on dual isolated loops, supporting up to 252 intelligent field devices per loop including smoke detectors, multi-criteria detectors, manual stations, relay bases, audible bases, and remote lamps.

Siemens 500-033090 features an onboard microprocessor that actively manages loop communication, diagnostic status, and isolator control. In the event of a short circuit on one zone, the loop isolator ensures the other zone continues to operate normally. This design enhances system reliability and helps maintain fire safety operation even under fault conditions.

Equipped with multiple LED indicators, the card provides clear visual feedback for power status, card health, communication failures, shorts, and other diagnostic conditions, making installation, testing, and maintenance more efficient.
