HY-C136 - The conventional heat detector is designed to ensure reliable fire detection thanks to the highly sensitive A2R thermal sensor, capable of monitoring abnormal temperature changes and quickly triggering the alarm. The 2-wire, non-polarity 4W-B technology simplifies installation and improves compatibility with conventional fire control panels and remote LED indicators. Featuring a non-addressable plug-and-play structure, it offers immediate configuration and simplified maintenance, while the acid- and corrosion-resistant materials ensure a long life. Compliant with the EN54-5 standard, it is ideal for hotels, offices, schools, warehouses and industrial environments. Dahua
