It works! 10 1

I bought this equipment to equip rental apartment and I can say it works quite correctly since he already had a trip to one of my tenants who had left the door of the kitchen and makes grills. The little smoke which has passed through the entrance, where the detector is installed, was enough to trigger it.

For the record, as the battery is new, the noise level is high and it was heard throughout the building, which triggered a (small) panic as she opened the door on the landing to ask for help, not knowing how to stop (it does not stop, we must drop the unit and disconnect the battery until the smoke clears).
