nebula wireless optical smoke detectors

nebula wireless detectors are optical devices that allows a very quick smoke and fire detection.

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. Both models are also available in wired version, extremely practice in cabling thanks to the separate base.
