CDPM Digital Paging Microphone
Setup And Installation Guide
CLOUD ELECTRONICS LIMITED
NOTE:
Setting the display only offsets the current microphone’s display, the offset does not
apply to the network zones. Thus, setting the display on a microphone will not effect any other
microphones on the network.
The automatic zone reset facility suits applications where the combination of selected zones
varies from one announcement to the next. This facility will automatically reset all previously
selected zones whenever the ‘TALK’ or ‘CALL ALL’ buttons are released or 30 seconds after the
last key-press. This feature is enabled by setting jumper J10 such that the header links the two
pins.
J10: Link indicates that zones should remain selected once talk button is released.
To reset the CDPM microphone to the software factory defaults (group memory empty, all zones
enabled), the unit will need to be powered up with jumper J7 linking the pins. Once the reset
has been performed, ensure that the header does not link the pins for subsequent power-ons.
J7: Resets all groups when power is reconnected to the CDPM.
Once the groups have been set and stored in memory, linking the pins on internal jumper J9 will
lock these group settings, to prevent groups being set during operation.
J9: Locks the groups.
NOTE:
J7 (non-volatile memory reset) takes precedence over J9(group lock). This means that
even if group lock is on when a NVM reset takes place, the group memory will be cleared.

There are two priority groups available for a CDPM microphone; high priority and normal priority.
All units come configured to operate at normal priority and as such will operate using a
'first-come-first-serve' protocol. To make a microphone high priority, link the pins on jumper J8.
J8: Link indicates that the unit is high priority
CDPMs that are on the same priority level will operate using the 'first-come-first-serve' protocol.
If announcements collide between a normal priority microphone and a high priority microphone,
the high priority microphone will take precedence (see section 3.5).
Microphones that are set to operate with high priority can still make an announcement if the
system is busy and not held by another high priority microphone. If the system is being used in
conjunction with other paging microphones which use the short-to-ground paging system, then
announcement collisions could occur between the high priority CDPM microphones and the
short-to-ground microphones.
