Fire alarm

The D9057B is an isolator base used to protect the fire alarm system from short-circuit faults. When a short circuit occurs on the loop, the base responds quickly and automatically isolates the damaged section. Once the fault is cleared, the base automatically exits isolation mode and reconnects the previously disconnected part back into the system. The device does not require coding and does not occupy an address in the system loop. Features: - Operates without occupying an address and takes up no space in the system loop - Can be used for an individual device (point isolation) as well as for a group of devices (area isolation) - Equipped with a yellow LED indicator that remains constantly lit during active isolation and turns off during normal operation

The SEC3008_HL_9000 is a loop module that includes two independent loops and is designed to work with LPCB and 9 series products. The board features LED indicators that display the fault/open circuit status of both loops, as well as the communication status between the loop board and the processor. The device is ready to use immediately upon installation, without the need for manual address assignment on DIP switches. Features: - 2 loops integrated on 1 board (supporting LPCB and 9 series products) - LED indicators for monitoring loop statuses and communication with the CPU
