OPERATING THE DMM 4650
General
All adjustments carried out at the appliance remain in memory even if the appliance is not connected to a
power source (EPROM).
Pressing the EXIT-key lets you step back and forth through the levels of the operation menu tree (page 1 1).
The stand-by mode is entered by pressing the EXIT-key when in the ”main menu” ’
If no key is pressed within a period longer than 5 minutes, the appliance enters the stand-by mode automatically
(except during recording and restore).
Stand-by
When the DMM 4650 is connected to a power source, the green POWER-LED lights, the display is dimmed,
and the relay outputs are set to their preprogrammed states according to the system’s configuration. This
stand-by status is remained until a control input starts a sequence. The display shows the sequence’s name
and number for the duration of the sequence. After completion of the sequence, the DMM 4650 re-enters
stand-by mode.
The states of the control ”outputs”, the audio relay ”bypass”, and the ”sum level” setting during stand-by
operation are set in the operation menu ”System setup” (page 26).
Password
Password-protection prevents the DMM 4650 from unauthorized operation. Three distinct user levels are available
which can be accessed by entering the respective password. As factory defaults, ”l 1 1 1 ” is programmed for Level 1
(easy operation), ”2222” for Level 2 and ”3333” for Level 3 (installer). Individual modification for each user is possible.
The menu tree diagram (page 1 1) shows which access is assigned to the respective user level.
Password entry, operation end
Pressing any key on the DMM 4650’s front panel, ”Password ?” appears on the display. Using the cursor keys you
have to enter a 4-digit number and confirm it with the menu key ok. After entering the correct 4-digit password, the
display shows the number of your user level. Using the cursor keys you are able to select the desired menu. The
EXIT-key cancels the operation and the appliance is protected against unauthorized use.
Priority function
With the DMM 4650 provides the opportunity to set priorities from 0 to 99; where 99 represents the highest priority
level. Setting the priority level leads in different results.
The priority of a sequence is defined by its free programmable priority setting (menu ”sequence” ”priority”). This
determines, whether e.g. a fire alarm sequence cancels a gong control sequence. Not the control line of an input, but
the priority number of the triggered sequence determines its priority. With equal priorities, the sequence that had been
started first remains valid.
The selected user level states the priority for the operation on the appliance. User level 1 = priority no. 33, user level
2 = priority no. 66, and user level 3 = priority no. 99. Modifying the default for lower user levels is performed within the
menu ”System setup” ”priority”’. The setting of the user priority controls, whether an operator gets interrupted by an
important sequences (sequence priority).
Users are able to modify messages, gongs, and alarms and save them as user presets. Depending on the actual user
level, the programs are automatically provided with the corresponding user priority numbers (see above). They are
maintained for the case that the original preset’s priority is lower. In this way it is guaranteed that user 1 cannot modify
the presets of user 2. In order to allow access for other users, the priority allocation can be modified downwards (lower
priority) by the respective user before storing a preset
(menu: ”message > priority”, gong” > ”priority”, ”alarm” > ’priority”)
If recording a message via remote recording, the priority number of the recording sequence is transferred to the
message.
