RELEASE DEV. DISABLE Releasing devices have been disabled.
SELF TEST FAILED Diagnostic test failed.
STYLE 6 POS. LOOP x There is an open circuit on the positive side of loop x. Style 6 and Style 7 are supervised methods of
communicating with addressable devices. If the control panel detects a trouble (open), it will drive both ends of
the loop, maintaining communication in an unsupervised method. The latching trouble will display on the panel as
a Style 6 trouble until you correct the condition and press
of ISO-X isolator modules.
STYLE 6 NEG. LOOP x There is an open circuit on the negative side of loop x. Style 6 and Style 7 are supervised methods of
communicating with addressable devices. If the control panel detects a trouble (open), it will drive both ends of
the loop, maintaining communication in an unsupervised method. The latching trouble will display on the panel as
a Style 6 trouble until you correct the condition and press
of ISO-X isolator modules.
STYLE 6 SHORT LOOP x Style 6 and Style 7 are supervised methods of communicating with addressable devices. If the control panel
detects a trouble (open or short), it will drive both ends of the loop, maintaining communication in an
unsupervised method. The latching trouble will display on the panel as a Style 6 trouble until you correct the
