Bosch FAP-425-OT-R Manual and Automatic Addressed Optical and Thermal Detector

This analog addressed detector combines optical and thermal sensors, with the address assignable automatically from the panel or manually entered on the device itself. The temperature channel reduces response time in fires that spread rapidly without producing smoke. It is used in areas with variable environmental conditions such as warehouses, workshops, and technical galleries. Since the same address can be manually assigned to a replacement device, the panel program does not need to be reconfigured after replacement.
