SETUP MODE PASSWORD PROTECTION
ACCESS
The MPM4 is equipped with a lockout function to prohibit
unauthorized modification of the system setup
parameters. Setup Mode is accessible to the system
installer in new units and the Mode Select button is
illuminated to indicate this condition. A default password
sequence (Zone 1, Zone 2, Zone 3, Zone 4) is encoded in
the unit, but only becomes effective when the Mode Select
button is held in for four seconds, which activates the
password and denies access to the Setup mode. The
Mode Select light goes out and only Normal Mode is
available to the system operator.
Unlocking Setup Mode
To gain access to Setup Mode, press and hold the Mode
Select button until the In and Zone buttons on the left
illuminate. Enter the password code sequence on them
and then press and release the Mode Select button. The
Routing display will blink once if the correct code sequence
has been entered, and the Mode Select button will
illuminate to indicate that the Setup Mode functions are
unlocked. Entering an incorrect code will return the MPM4
to Normal Mode.
Changing the Password
Custom passwords can be created by the system installer
to protect the settings of the Setup Mode. Passwords can
be from 0 to 8 characters long and are created from
pushing a pattern of the In and Zone buttons.
To change the password, simultaneously push and
release the Zone 1, Zone 4 and Mode Select buttons. The
In and Zone buttons on the left all illuminate. Push the
desired sequence of buttons and then activate it by
pushing the Mode Select button, which will begin flashing.
The password sequence must then be correctly repeated,
followed by pushing the Mode Select button to validate it.
Successful reentry will cause the Routing display to flash
twice and the Mode Select button to be fully illuminated.
An incorrect verification sequence will cause the MPM4 to
exit the Password Change mode. Setup Mode is still
accessible and the previous valid password is still
recognized by the MPM4.
In the event Setup Mode adjustments are required and the
password is unknown, it is possible to reset the MPM4
back to the default password. Disconnect the power from
the unit and locate the two-pin shorting jumper on the back
of the display circuit board behind the LED matrix inside
the MPM4. Remove the jumper plug and push it onto the
Password Reset pins #2 and #3 located on the three-pin
reset header to the left. (See diagram.)
Apply power, wait for the turn on sequence to complete and
remove power. Return the two-pin jumper plug to its storage
pins. The password is now reset to (Zone 1, Zone 2, Zone 3,
Zone 4) and Setup Mode is automatically unlocked.
