Mentrex Flamestop GS599

Wireless network with up to 30 participants, even without a gateway. In case of an alarm, all detectors trigger the alarm sound and can be silenced together by pressing a mute button. Can be connected to a smartphone via a gateway (not included) and Wi-Fi. Features a photoelectric sensor, maintenance-free and user-friendly. Compatible with the Flamestop GS188 gateway. Comes with 2 replaceable AA batteries. The GS522 is a photoelectric smoke detector. It responds sensitively and reliably to slow smoldering fires that produce thick, black smoke at low heat before open flames develop. The red LED blinks once every 50 seconds to indicate operational readiness. When the battery is low, a periodic beep sounds, which can be silenced for 10 hours using the mute button. At least one smoke detector should be installed in every room of the house, except for the kitchen and bathroom.
