5.1 Walktest Mode
The MS-2410BC provides the capability to perform a walktest of the system without triggering the ACM-8RF zone
relays, the system annunciators or the alarm output relay. Walktest Mode allows for testing of the 10 zones (initiating
device circuits). An audible or silent walktest may be performed.
For an audible walktest, 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 Notification Appliance
Circuits 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 steadily. Prior to entering Walktest Mode, check to be certain that all system faults
have been cleared.
Note that trouble relays will be activated while the control panel is in Walktest Mode. Placing the control panel into
Walktest Mode will only be possible if the system has no active alarms.
The keypad is enabled, to allow switching from Normal Mode to any other mode, by inserting the Security Key into
connector J4 on the MS-2410BC main circuit board.
Insertion of the Security Key alters the functions of the keypad. Insert the supplied programming keys function label
C to view the new key functions. Keys labeled 1 through 4 may now be used for entering a numerical password.
Walktest Mode is entered by keying in the Walktest Mode password (1231233) and pressing the Enter key. If an
incorrect key is pressed, wait 10 seconds and then reenter the proper password before pressing the Enter key.
A pause of up to 10 seconds is allowed between each key press while entering the password. After pressing the
Enter key, the control panel will be in Walktest Mode with the keypad key functions configured for this mode. The
System Trouble LED and AC Power LED will blink at a rate of 1 second On and 1 second Off and the trouble relay
will activate. A pause of up to 30 minutes is now allowed between each key press and device activation while in
Walktest Mode. Delays longer than 30 minutes will cause the control panel to exit Walktest Mode. If the Security
Key remains inserted when the control panel returns to Normal Mode, the panel and keypad will function as expected
in Normal Mode. The Security Key must be removed and then reinserted in order to reenter Walktest Mode or to
enter any other mode.
Once in Walktest Mode, the control panel will immediately:
• Flash the Trouble LED and AC Power LED
• Activate the trouble relay
• Turn on the Notification Appliance Circuits for four seconds for the first alarm on a zone if an audible walk-
test is performed. Subsequent alarms will sound for one second. Troubles cause the NACs to remain on. For
a silent walktest, all NAC outputs remain off
• Disable the alarm relay
