Introduction Safety Information Cloud PM paging microphones operate from a low DC voltage, supplied by either an AC adaptor or the Cloud host device to which the microphone is connected. As such, the microphone requires few safety precautions. However, note that both the metal base of the unit and the mic gooseneck will be electrically connected to the chassis of the host device (e.g., Cloud zoner or mixer/ amplifier) once the installation is carried out.
Overview Thank you for purchasing this Cloud PM paging microphone. Six models of the PM are available: • The PM4, PM8, PM12 and PM16 are Digital Paging Microphones able to page to 4, 8, 12 or 16 zones respectively. • The PM4-SA and PM8-SA are Digital Paging Microphones with built-in Message Announcer capability. They can page, or send messages to 4 or 8 zones respectively.
Multiple PMs may be interconnected (via the Digital Paging Interface) to permit paging from more than one location. A total cable run of up 1 km is permissible, with a maximum of 32 PM units. Different models of PM may be intermixed on a single network. It is also possible to configure a PM to address only a subset of the available zones. The PM is also compatible with the older Cloud CDPM range of digital paging microphones.

Memory cards SA models of the PM accept standard SD cards with a capacity of up to 2 GB or SDHC cards up to 32 GB. MiniSD/MiniSDHC or MicroSD/MicroSDHC cards can also be used with the appropriate adapter, up to the same maximum capacities. To access the memory card slot, first disconnect the PM from its power supply source (if necessary) according to the powering method - by unplugging the external PSU, the Digital Paging Interface CAN OUT connector, or by turning off the host mixer.
UNLOCK (for recording) SD CARD WRITE-PROTECT TAB LOCKED (when installed) Filenames SA models of the PM will recognise files of the above types with the following filenames: Message files: M_x.mp3 or M_x.wma Chime files: C_x.mp3 or C_x.wma In both the message and chime filenames, x must have a value between 1 and 8. Thus valid message filenames are M_1.mp3 to M_8.mp3, and valid chime filenames are C_1.mp3 to C_8.mp3 (or their *.wma equivalents). All other files on the memory card will be ignored.

Installation Accessing the internal PCB With most installations, it will be necessary at some point to access the PM’s internal PCB. Access is required to make connections to the analogue interface (possibly including DC power connections) and to connect the associated audio output, to move the various configuration jumpers, to adjust the mic or chime levels and, on the SA models, to connect to the external message trigger inputs, if used.
replacement before mounting the PM on the wall. The metal baseplate of the PM is fitted with two keyhole slots which provide a simple method of wall mounting. The PM can be wall-mounted on two round-head or pan-head screws with heads of between 5 and 10 mm dia. At the desired location, drill two holes in the wall 183 mm apart horizontally. Use a drill appropriate for the wall construction and type of wall fixing employed.
of this connector). (Note that this connector is also used for the internal chime speaker.) Disconnect the gooseneck by undoing the three relevant screw terminals on the connector. The gooseneck itself may now be removed by undoing the 14 mm nut securing it to the casing – a box spanner is the best tool for this. Fitting the MI100166 gooseneck assembly is the reverse procedure.
Powering standard (non-SA) models from a Cloud host mixer If the PM is to be connected to a Cloud host mixer, DC power may be obtained from the mixer as long as it has a suitable power supply connection, and the spare current capacity of the mixer is sufficient. As a general rule, a mixer cannot supply power to a PM that has more zones than itself.

Powering SA models from a Cloud DCM-1 SA models of the PM may be powered from a Cloud DCM-1 Digitally Controlled Mixer. Other Cloud host mixers, such as the Z4II/Z8II or 46/50, have insufficient spare current capacity to power SA models of the PM. Note that if the PM is being powered from a DCM-1, an external PSU should not be simultaneously connected.
Cables and Connections Connecting the PM to a mixer via the digital interface The rear of the PM is fitted with two RJ45 sockets labelled CAN PORTS. These constitute the Cloud Digital Paging Interface, which connect the PM to the host mixer, and/or to other PMs on a network in a multiple-PM system. Where a mixer has facility for both digital and access contact connection, the digital connection should be used.
IMPORTANT: The Digital Paging Interface is a data network, and thus must be terminated at both ends. In a system comprising a single PM, this means terminations must be set in both the PM and the host mixer. In systems with multiple PMs, it means terminations must be set in the PM at the ‘end’ of the chain and the host mixer. See “Terminating the Digital Paging Interface” on page 42 for details of how to set terminations.
2. Zone Selection Control Cable: The zone selection control cable should be a multicore stranded type with an overall screen. The number of cores required depends on the number of zones supported by the particular PM model (PM4, PM8, etc.), and whether DC power is to be derived from the host mixer via the control cable (see “Power Requirements” on page 22). One core is required for each zone to be connected, plus a core for the 0 V connection, plus one further core for DC power, if needed.
Typical example The diagram below shows the overall cable connections between a PM4 and a Cloud 46/50 host mixer (which has a typical 4-zone short-to-ground access port). PM4 PAGING MICROPHONE TERM1 +V TERM2 0V 0V Z1 Z2 Z1 Z2 Z3 Z3 Z4 +V TERM8 Z4 PAGING ACCESS HOT COLD GND HOT COLD GND MIC 1 IN 46/50 MIXER Note in this example that as Zones 5-16 are not in use, no connections need to be made to Z5-Z8 on TERM2, or to Z9-Z16 on TERM4.
Connecting a PM-SA for external message triggering: These connections are optional, and will only be required if the PM-SA’s internal messages are to be triggered by external contact closure. Examples of such applications include: • • • • • • Programmed triggering via relays in external control systems (e.g., Crestron, AMX, etc.
The external message trigger inputs should ideally be connected to volt-free switch or relay contacts, which may be either NO (normally-open) or NC (normally-closed). This choice is set by moving J20, J21, and, (on the PM8-SA only), J22. The three jumpers allow selection of NO or NC independently for: M1 and M2; M3 and M4; M5 to M8 (PM8-SA only). See “PCB layout diagrams” on page 49 for location of the internal jumpers. The triggers are momentary – i.e.
Configuring the PM Zone Groups Zones may be ‘grouped’ together to simplify the procedure for paging several zones simultaneously. Up to four groups (A to D) may be defined on PM models PM4, PM8, PM12, PM16 and PM4-SA, and up to eight groups (A to H) on model PM-8SA. Using groups simplifies operation for the user; when a GROUP button is pressed, the LEDs corresponding to the zones comprising the group illuminate, to give confirmation of which zones are to be addressed.
Assigning a message to a zone group (SA models only) On the SA models, any one of the message sound files on the SD memory card may be assigned to a zone group. In this case, when a GROUP is selected, the LED corresponding to the message will illuminate as well as those for the zones comprising the group. When the TALK/SEND button is pressed, the message that has been assigned to the group will automatically be broadcast to the zones comprising the group.
7. Release the GROUP button. Note that once a chime is assigned to a group, it is not possible to check which chime it is, as pressing a GROUP button will illuminate the zone and message LEDs, but gives no indication corresponding to the chime. Note also that if a chime number is assigned for which no chime file exists, the group will operate normally, though there may be a slight delay before a message starts. Setup options The PM has a number of setup options which can be configured during installation.
Zone offset applies only to the whole set of zone buttons on a PM, not to individual zone buttons. Thus the zone buttons can only ever address a numerically-consecutive subset of the available zones. If an offset is applied which makes one or more buttons address a zone number higher than the system maximum of 16, the numbers “wraparound” back to 1. Thus applying an offset of 13 to a PM4 would result in its four zone buttons selecting Zones 14, 15, 16 and 1 respectively.
Auto-Reset of Zone and Message Selection By default, the last zone selection and message selection (SA models only) made remain in place after the announcement (or message broadcast) has been made. This enables a supplementary announcement to be made to the same set of zones without selecting them a second time, or for the pre-recorded message to be repeated without re-selection. The retained zone and message selections are indicated by the front panel LEDs.
Priority settings NOTE: This configuration option is only relevant to systems with more than one PM. A PM microphone may be set to either NORMAL or HIGH priority; the factory default is NORMAL. Paging (or message initiation) on a network with multiple PMs all set to NORMAL priority will operate on a ‘first-come-first-served’ basis.
a diagram showing jumper and level adjustment locations. Chime selection is permicrophone, and setting the chime on a PM will not affect any other PMs on the network. The table below gives the jumper settings for each chime: Selection J3 J2 J1 J5 No Chime ANY ANY ANY OFF Chime 1 ANY OFF ON ON Chime 2 ANY ON OFF ON Chime 3 ANY ON ON ON Chime 4 ON OFF OFF ON Additionally, the internal speaker can be turned off, by setting jumper J6 to OFF.
Message chimes Pre-recorded messages may also be preceded by a chime, and the selection of this is independent of the page chime. Jumper J2 enables or disables the message chime. It is often considered desirable to precede pre-recorded announcements by a different chime to spoken announcements, and thus J3 allows the message chime file to be either C_1 or C_2*.
Disabling Zone buttons It may occasionally be desired to restrict the zones which a microphone can access. To permit this, zones may be disabled. Note that the disabling of zones is on a perunit basis, and other microphones in a multiple-PM system will still have free access. On SA models, disabling zone buttons affects both paging and messaging functions. To disable particular zones on a PM, proceed as follows: 1. 2. 3. Set jumper J7 to ON, and power the unit on (thus performing an NVM reset).
Terminating the Digital Paging Interface The Cloud Digital Paging Interface must be correctly terminated at its ends for errorfree operation. In systems using a single PM connected to a host mixer via the digital interface (such as the Cloud DCM-1), the terminations should be ON at both the PM and the mixer. In systems with multiple PMs, only the mixer and the PM at the ‘end’ of the chain should have their terminations set ON; ‘intermediate’ PMs should have their terminations set to OFF.
Setting the terminations on the Cloud DCM-1 The Digital Paging Interface is referred to in the DCM-1 documentation as the ‘CDPM bus’. The termination is set by the DCM-1’s internal jumper J2, and is ON when J2 is in place. This is the factory default setting, and is unlikely to require changing. The diagram below shows the jumper’s location. (UPPER PCB) J2 (LOWER PCB) KEY: Jumper with one position (i.e.

Systems with multiple paging microphones Connecting a single Cloud PM microphone to a host mixer is quite straightforward.

All other PMs on the network must be powered individually by external PSUs. DC power is only connected internally at the CAN PORT OUT socket, so the ‘daisychain’ data/audio connection cannot be used to pass power between PM units.
Communication between PMs will be via the digital interface, and between the last PM (effectively the whole network) and the host will be via the analogue interface. Consideration needs to be given to any zone offsets applied to the various PMs on the network. For example, in a 12-zone system with three PM4s configured to page Zones 1 to 4, 5 to 8 and 9 to 12 respectively, analogue port terminals Z1 to Z12 inclusive will need to be wired to the host mixer(s) for correct operation.
Using the analogue interface with third-party paging microphones. It may sometimes be necessary to interface a system consisting of one or more PM microphones to a third-party paging system which uses short-to-ground contacts for paging access. This implies that the host mixer has an analogue paging access port. Only one PM in a network will require the analogue interface for the whole network to be connected to a short-to-ground paging system.
Appendix PCB layout diagrams When removing jumpers we recommend that the link is left connected to one leg of the header to prevent loss of the link. When making internal adjustments please ensure that you: • • Disconnect power to the unit before accessing the PCB. If the microphone is powered from another unit, this will mean removing the appropriate connection. Only reassemble the unit using the original screws.
