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 prityio 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.
