Walktest Mode
The MS-5024UD provides the capability to perform a one-man walktest of the system without triggering the commu-
nicator, the zone relays or the alarm output relay. Walktest allows for testing of the five zones (Initiating Device Cir-
cuits). The first initiating device activated on a zone will cause the Notification Appliance Circuits to turn on for four
seconds. Subsequent device activations on the same zone will cause the NACs to turn on for one second. Any smoke
detectors that are activated will be reset. Zonal faults (open circuits) will cause the NAC to remain on steady. Prior
to entering Walktest Mode, check to be certain that all system faults have been cleared.
Note that the trouble relay
will be activated while the control panel is in Walktest Mode. Placing the control panel into this mode will only be
possible if the system has no active alarms.
Pressing the
MODE
key followed by the 4-digit code
9255
and then the
[ENTER/STORE]
key will place the con-
trol panel into Walktest Mode.

Once in Walktest Mode, the control panel will immediately:
✓
Blink the trouble LED
✓
Activate the trouble relay
✓
Turn on the NACs for four seconds for the first alarm on a zone. Subsequent alarms on the same zone
will sound for one second. Troubles cause the NACs to remain on
✓
Disable the alarm relay
✓
Display all alarm conditions as they occur
✓
Display all zone troubles as they occur
✓
Display ground faults as they occur
✓
Transmit 'off normal' message to Central Station(s)
✓
Continue to communicate any events not acknowledged at a Central Station prior to entering Walktest
Mode
During Walktest Mode, zonal activity is displayed in real-time as it occurs. At the end of walktesting the system, the
display will show the last event that occurred. To view all events stored during Walktest, use the Up arrow, Down
arrow and 1st Event keys. The Down arrow key moves the Walktest list to show older (previous) events. The Up
arrow key moves the Walktest list to show newer (more recent) events. Pressing the 1st Event key at any time will
cause the display of the first event stored upon initial entry into Walktest Mode. While in Walktest Mode, the control
panel will store up to 128 events in the Walktest File for later recall and display. A printer may be connected to the
panel during Walktest. All Walktest events are printed in real-time as they occur.
To return the control panel to Normal Mode, press the
MODE
key followed by the code
6676
and then the
[ENTER/
STORE]
key. Any delay between key presses greater than 10 seconds causes the control panel to remain in Walktest
Mode.
The control panel will automatically return to Normal Mode if no system activity has occurred for 60 minutes. This
includes pressing any keys or activity on any zone. Exiting Walktest Mode leaves the Walktest file in memory such
that it may be printed in Print Mode. Subsequent entries into Walktest Mode will delete the Walktest file.
Note that remote site upload or download is not possible while in Walktest Mode.
