Product Overview

The PM Range of Paging Microphones are designed for general purpose multizone applications and can also be used with non-Cloud products.

Four models of the PM are available: the PM4, PM8, PM12 and PM16. The models differ only in the number of zone select buttons on the front panel (4, 8, 12 or 16 respectively), and consequently in the maximum of zones that can be supported.

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 digitalpaging microphones. PM microphones and CDPM microphones may be freely intermixed on the
Digital Paging Interface.

             Can interface upto sixteen zones from linked PMs
  • PM8: Eight zones
             Can interface upto sixteen zones from linked PMs
  • PM12: Twelve zones
                Can interface upto sixteen zones from linked PMs
  • PM16: Sixteen Zones



  • Pre announcement chime: Choice of four chimes selected by internal jumper
                                             Chime can be set off/on by internal jumper
