How to Do a Walk Test 3. Status Change
NFS-640 Programming Manual P/N 51333:B 10/03/2003 51
Operate the control panel in Walk Test as follows
Basic Walk Test directs the control panel to do the following:
• Activate silenceable outputs associated by programming with each new alarm. (The panel does
not activate non-silenceable outputs.)
• Save and store each test in the History buffer
• Send a TEST Axx status banner for each alarm, and a TEST TXX banner for each trouble, to
the printer (xx equals the number of tests for a detector or input device with this address)
• Turn on the System Trouble LED
• Turn on the System Trouble relay
• Disable activation of the System Alarm relay
Advanced Walk Test
During Advanced Walk Test, when the tester activates an input, all CBE mapped to that input will
activate with the exception of releasing functions. Each input activation is latching; that is, it will not
deactivate until the system is reset. Advanced Walk Test will sound all activated outputs, overriding a
setting of “
*” (silent) in the Walk Test field.
Note: Some detectors, laser detectors for example, can be difficult to place in alarm using a magnet. Advanced Walk
Test facilitates magnet testing of these detectors.
Enter Advanced Walk Test as follows:
Enter LTEST at the password screen. Asterisks will display where LTEST has been
typed. Pressing
ENTER displays the following screen.
Note: The control panel cannot be put into Walk Test from an alarm condition.
Advanced Walk Test directs the control panel to do the same as it does for Basic Walk Test (see “Basic
Walk Test” above) with the following exceptions:
• alarm and trouble messages are sent to the printer, not test messages. (These Walk Test
messages can be distinguished from others at the printer because they begin with the trouble
message generated when Walk Test is entered, and end with the cleared trouble when Walk
Test is exited.)
• all CBE mapped to the test input is activated except releasing functions.
