Six Isolator Module and Engineering Specifications six isolator module shall be a System Sensor model number ISO 6 Isolator modules automatically isolate wire to wire short circuits on a signaling line circuit SLC loop Each module circuit shall limit the number of modules or detectors that may be rendered by a short circuit fault on the SLC Loop If a wire to wire short occurs the isolator shall automatically open circuit disconnect the SLC loop When the short circuit is corrected the isolator module shall automatically reconnect the isolated section of the loop isolator module shall not require any address setting and its operations shall be fully It shall not be necessary to replace or reset an isolator module after its normal module circuit shall have an LED that is controlled by the panel to indicate module status signals transmitted from the panel can cause the LED to blink latch on or latch off to the control panel technical documentation for module LED status operation Agency Standards ANSI UL 864 Control Units and Accessories for Fire Alarm Systems ULC S527 Control Units for Fire Alarm Systems FM ANSI NFPA 72 National Fire Alarm Code 2009
