The compact design of this smoke alarm has been conceived in such a way that it can be installed with only the integrated battery. There is no need for drilling, as it can be attached to any stable surface in the house using double-sided adhesive tape. It detects smoke early and effectively, and emits an alarm of over 85 dB. Equipped with the NB-IoT wireless standard, the device can also send the smoke notifications to a smartphone, in order to warn the resident immediately of the danger.
