1 General information This operating manual describes the following variants of the duct smoke detector: • RM-O-3-D for 24 V DC supply • RM-O-3-D for 230 V AC supply To ensure correct functioning of the RM-O-3-D duct smoke detector it is essential to read the provided operating manual before starting any work, and to comply with it. This manual must be given to the system owner when handing over the system. The system owner must include the manual with the system documentation.
2 Safety and correct use General information regarding safety Correct use Only specialist personnel are allowed to perform the described work on the duct smoke detector. Only skilled qualified electricians are allowed to work on the electrical system.
3 Product description Functional description To prevent smoke from spreading in buildings, it is extremely important that it is detected at an early stage. The RM-O-3-D duct smoke detector is used to signal to and release fire dampers and smoke protection dampers. The duct smoke detector operates on the principle of light scattering and detects the smoke regardless of its temperature so that fire dampers can be closed before the release temperature is reached.

1 PageHeaderToc Installation The RM-O-3-D duct smoke detector can be installed into the inspection access of FK-EU fire dampers. For the exact position see the illustration on the right. If FK-EU is used as an air transfer damper according to general building inspectorate licence Z-6.50-2031: Install the RM-O-3-D duct smoke detector in the upper inspection access of the fire damper. Proceed as follows: 1. ③ ② ④ panel is used for centering). 2. Remove the inspection access panel by turning and lifting it.
2 6 Einbau 1 PageHeaderToc Installation into a duct or an extension piece Duct installation ① Proceed as follows to install the RM-O-3-D duct smoke detector: ② ③ Note The sensor head has to be permanently in the airflow as otherwise its function will be impaired. Consequently: • 1.5 × H minimum distance between duct smoke detector and any bend, control unit or other obstacle. • Place the duct smoke detector in the upper third of the duct (not near a corner). 1.
