Operating Instructions
Walktest
4.18 Walktest
Walktest is a feature which allows one person to test the fire alarm system. An audible walktest
will momentarily sound the Notification Appliance Circuits in the building and store the walktest
information in a file at the panel. A silent walktest will not sound the NACs but will store the walk-
test information in a file which can be viewed at the panel. Disabled NAC devices will not activate
during walktest. In addition, i
3
smoke detectors will enter their own test mode causing their LEDs
to flash twice every five seconds (refer to i
3
specification document).
Alarm/Shorted Condition
When in audible Walktest, the panel responds to each new alarm and activates the NACs for four
seconds. It also stores each alarm in the walktest history file which can be sent to an optional
printer. The stored display will be the same as if the device actually activated except the colon (
:
)
in the time stamp is replaced with an asterisk (
*
).
Open Condition
IDCs and all main circuit board NACs are monitored for fault conditions during Walktest mode.
When an open condition occurs on an IDC, the FACP will activate all enabled NACs during an
audible Walktest and remain activated until the open condition is cleared.
While in Walktest, the trouble relay is activated and the system Trouble LED flashes (as in all of
the Program and status change operations). The alarm relay is not activated.
4.19 Read Status
Read Status functions do not require a password. The control panel will continue to provide fire
protection while in Read Status mode. This mode can be entered while the control panel is in alarm
or trouble. If a new alarm or trouble occurs during these functions, the Read Status is exited to pre-
vent confusion.
Read Status Entry
When the operator presses the control panel
Enter
key, the LCD will display the following:
Pressing
1
, while this screen is being displayed, will cause the control panel to enter the Read Sta-
tus mode which allows the user to view and print the programmed features and status of the control
panel.
NOTE:
In Walktest, a NAC open or short fault will not cause the NACs to activate.
