Patent number: 10069293Abstract: 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.Type: GrantFiled: March 2, 2016Date of Patent: September 4, 2018Assignee: Tyco Fire & Security GmbHInventors: Faruk Meah, Andrew D.
