Design concept: 6 smoke inlet holes are surrounded, and the wall-mounted design is more conducive to the smoke inlet and alarm quickly.
Practicality: 360 surround lights with no dead angle, the conventional smoke is usually a weak green light flickering, and the single-point light is very abrupt. This smoke sense is a full circle of light, and the hanging roof is more like a lighting decoration, flashing once every 60 seconds, like a living life, endless. When an alarm is issued, the red light flashes rapidly and continuously to warn of danger in all directions and inform users to evacuate urgently.
Appearance: circular structure, arc design, elegant and beautiful, divergent ring design, more visual impact.
