Cloud Electronics PM16 - Manual (Page 8)

PM4/8/12/16 & PM4/8-SA Installation and User Guide v1.0 8
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. PM microphones and CDPM microphones may be freely intermixed on
the Digital Paging Interface.
Scope of this manual
The bulk of this manual is intended to guide you through the installation and
configuration of the PM. Sections of the manual cover aspects such as power
requirements, connecting the unit to various types of host mixer, and configuring
the PM to suit the particular requirements of the installation. These sections will be
adequate for situations where there is only a single PM. A separate section covers
the various additional points that need to be considered when multiple PMs are
interconnected on a network.
The manual covers both standard PM microphones and the SA models, which include
a digital sound store for pre-recorded messages. The installation and operation of
the two models is similar in many respects; nevertheless there are some important
differences between the models. These include the additional wiring needed if the
stored messages are to be triggered externally, and the internal PCB layout and
jumper locations.
The sections of the manual which are specific to the PM4/8-SA are clearly indicated
by the use of a this icon
Wherever the term “PM” is used in this manual, the text can be taken to apply to all
models (both SA and non-SA) of the microphone. Similarly, the term ‘TALK’ can be
taken to correspond with the term ‘TALK/SEND’ on the SA model.
The procedures for mounting a PM on a wall and changing the standard gooseneck
mic for a shorter one are also described.
In addition to the installation aspects, a User Section includes a simplified
description of the PM’s operation; it is recommended that installers should
photocopy this section (or download a PDF copy of this manual from the Cloud
website and print the section off), and leave a copy for the operator.
