nebula optical smoke detectors
nebula detectors are optical devices that allows a very quick smoke and fire detection respecting DIN EN 54-7 normative (wired version) or EN14604:2005 (stand-alone version). They can be directly wall-mounted (in vertical) or at ceiling. Both models are fitted with a separate base available in silver and white. Thanks to the handy bayonet the installation is completed by screwing the detector on the base. There are two versions: the first with silver mesh, the second with circular glass design. Both versions of the device have a red LED for alarm event.
All models are also available in wired version, extremely practice in cabling thanks to the separate base.
