摘要： An isolator circuit (25) for a unit of a safety system (10) includes a power control line (14) connectable to a first loop of a safety system and a power connection (16) connectable to a second loop of the safety system. A switch (26) is connected to the power control line (14), and the switch has a closed configuration and an open configuration. A controller (28) controls the configuration of the switch (26). If a voltage across the circuit (10) from the power connection (16) to the power control line (14) falls below a predetermined level, the controller (28) opens the switch (26), thereby causing a disconnection to occur in the first loop.

摘要： The system includes an active unit, such as a detector unit, which has a processor, a network port for connection to a central control unit, and an optical data input port. The processor is arranged to enable the optical data input port on receipt of an enable signal received by the active unit from the central control unit via a network.

摘要： The present disclosure provides an alarm call point which is able to discriminate between activation in an alarm situation and activation in a test situation (e.g. activation using a test key). This arrangement allows an alarm system to be tested without needing to put the control panel into a special test mode, making it easier and quicker to install, commission and test the system.
