If the problem remains, or if it is connected to the auxiliary power supply and the bus
simultaneously, follow the steps indicated in chapter 6.1
6.4 THE VOICE ANNOUNCEMENT IS VERY LOUD/LOW.
If this situation is similar in all the elements connected to the bus, check the con figuration
of the equipment where it is connected (NEO).
In case there is a speci fic MPS-8Z unit, check the con figured volume according to chapter
4.4.6.
RESET the unit (the equipment must be con figured again). In this case, press
simultaneously the buttons “CANCEL”, “EVENTS” and “MEMORY” for 5 seconds. The equipment
will restart. Con figure the address accordingly (see 4.2).
If this procedure does not work, disconnect the unit from the ACSI bus and contact LDA's
Support Department. Once the unit is removed, if there are more units connected in the bus,
connect the inputs and outputs lines of the ACSI bus in order to keep the system functioning in
normal operation.
6.5 IS NOT POSSIBLE TO HEAR THE VOICE ANNOUNCEMENT
Check that the output volume con figured in the equipment is correct according to chapter
6.4.
If the problem remains, activate the gong signal according to chapter 4.4.2. Perform a call
and check that the gong signal can be heard correctly. If this is the case, the microphone's
gooseneck might had been damaged. Contact LDA's Support Department/RMA and ask for a
replacement.
You can keep using the equipment while the gooseneck is being replaced, by using an
external microphone and following the steps of chapter 4.4.3.
If the gong signal does not sound, perform a RESET (the equipment must be con figured
again). In this case, press simultaneously the buttons “CANCEL”, “EVENTS” and “MEMORY” for
5 seconds. The equipment will restart. Con figure the address accordingly (see 4.2).
If this procedure does not work, disconnect the unit from the ACSI bus and contact LDA's
Support Department. Once the unit is removed, if there are more units connected in the bus,
connect the inputs and outputs lines of the ACSI bus in order to keep the system functioning in
normal operation.
6.6 THE EXPANSION KEYBOARD DOES NOT ADDRESS THE SELECTED
ZONES.
If when pressing the memory button several zone memory indicators of different
keyboards are switch on, the identi fier of one keyboard is not correct, or is the same as other unit.
Check the identi fier according to chapter 4.3
If the problem is still present, check the connection between the MPS-8Z and the
expansion keyboard, as indicated in chapter 4.3
If previous actions do not solve the problem, perform a RESET (the equipment must be
con figured again). In this case, press simultaneously the buttons “CANCEL”, “EVENTS” and
“MEMORY” for 5 seconds. The equipment will restart. Con figure the address accordingly (see
4.2).
