7.8.11 System Fault
The Walk Test™ has the ability to test signal circuits for fault (i.e. open/short)
conditions. This is accomplished by using the Walk Test™ output lists (L50 through
L57) as the input lists for signal fault conditions.
For example, if a signal circuit fault occurs on a point in Walk Test™ output list L50
(Group 0), and Walk Test™ Group 0 is enabled, the Walk Test™ fault code will play
on all signal/speaker circuits in Walk Test™ list L50. Note that the signal fault is not
inhibited. An actual fault condition will occur at the operator interface panel, but will
be logged as a Walk Test™ fault for that signal. This fault automatically clears when
the signal circuit is returned to normal in a Global Acknowledge system. In an
Individual Acknowledge system, Point P4 (FORCE GLOBAL ACKNOWLEDGE)
must be turned ON before performing a signal circuit Walk Test™. If Walk Test™ is
not enabled for the group containing the signal circuit in fault, the fault condition
passes through without playing the Walk Test™ code.
7.8.12 Fault Audible
When a zone fault is detected, the Walk Test™ signals sound continuously for four
seconds.
7.8.13 Zone Code/Zero Code
The <F3> key is used to enable/disable Zone Coding. By default, Zone Coding is
enabled.
7.9 Walk Test™ PROCEDURES
Before the Walk Test™ can be performed, the operator must enter the correct
passcode.
7.9.1 How to Enter a Walk Test™ Passcode
