Hekatron optinen savukytkin ORS 2 / LRS 01 / LRS 02 (5000614-0201)

This optical smoke switch is built for smoke control systems that must react quickly and reliably. Unlike generic detectors, it is purpose-matched to Hekatron ORS 2, LRS 01, and LRS 02 control units, providing a potential-free changeover contact for direct integration into building automation and fire protection circuits.

Highlights

• Optical scattered light detection principle
• Compatible with Hekatron ORS 2, LRS 01, and LRS 02 control units
• Potential-free changeover contact (relay output)
• Contamination compensation and self-monitoring
• Test function and alarm memory
• White ABS housing (RAL 9010)

In daily use

The switch operates from a 24 V DC supply (18–30 V DC range) and draws only 100 µA in standby, making it suitable for continuous monitoring in smoke control systems. In alarm condition, current consumption rises to 10 mA and the relay changes state to signal the control unit. The device is designed for ceiling mounting using a separate detector base.
