Program Change - Level 2
3.4.2 Clear History
Pressing '2' displays the following screen:
Press the ENTER key to clear the 500-event History file. Press the left arrow key (backspace) to exit without clearing
the History file. Caution: Pressing Enter will clear all History events associated with this panel. Care should be taken
to ensure this is the appropriate action.
3.4.3 Walktest
If '3' is pressed, followed by ENTER, the following is displayed:
Press '1' to perform a silent walktest with all sounding devices, control modules and the NAC 1 and NAC 2 outputs
OFF. Select '2' to perform an audible walktest which sounds all silenceable control modules and NAC 1 and NAC 2
(if programmed as 'BELL_CKT' as explained in "Point Edit" on page 60) output during walktest. Disabled NAC out-
puts will not activate during walktest. Each alarm and trouble condition (short and open) will be printed in real-time
and stored in the 500 event history buffer. After pressing either '1' or '2', the screen shown below will appear:
If ENTER is pressed, the second line goes blank and the unit is in Walktest mode. Walktest may be stopped at any
time by pressing the left arrow key (backspace), returning the unit to the main screen. A one hour time-out automati-
cally returns the system to normal operation.
Shorted/Alarm Condition
When in Walktest, the panel responds to each new alarm and activates its programmed control outputs for four sec-
onds, if those control outputs have been programmed for silenceable activation. It also stores each alarm in the his-
tory file and printer with a 'TEST XX' status label. XX is a count of the number of times a device with this address
has been tested. Note that this is a convenient way to identify two detectors that are erroneously set to the same
address. A complete Walktest will cause a 'TEST 02' indication for the addresses to which both devices are set and no
TEST report for the address that one of the devices should have been set to.
