A bus module that protects four wired inputs with adjustable EOL resistance values, four galvanically isolated signal PG outputs and an additional power supply, with an electronic fuse. Besides the resistance of the EOL type, the values of resistors can also be set for the inputs. The outputs are designed as galvanically separated units (two each have a common C-terminal). The module occupies four positions in the control panel and is equipped with one tamper sensor for and one behind.
It is especially suitable for the renewal of wired alarms, where old detectors are used. They are also very often used to control multiple devices through the PG outputs. The auxiliary power makes it possible
