The Cloud PM-SA range of Digital Paging Microphones have been developed from the recently-introduced PM range, which were themselves designed to improve on the well-known CDPM Series. As well as being a simple-to-use and elegant paging mic, the PM-SA models incorporate a digital sound store for pre-recorded messages. These can be triggered either manually, or via external contacts from third-party equipment, such as PIR sensors, timing systems, or similar. The PM-SA models have a powerful range of options that make them suitable for almost any situation, yet are easy to install and configure.
Spot Announcer messages are stored on a standard SD memory card, and can be in the form of either WMA or MP3 files, at most common sample and bit rates. Pre-announcement chimes are also stored on the card in the same formats, and the unit may be configured to precede paged and pre-recorded announcements with different chimes.
An important feature of the PM-SA is its ability to store specific messages (and chimes, if wished) as part of the PM's zone group feature. A zone group allows multiple zones to be selected for paging or messaging with a single key press. When a message is programmed as part of a group definition, the message may be triggered by an external command, when it will be automatically broadcast in all the zones forming that group. This opens up many possibilities for automatic messaging, such as connecting the external trigger inputs to third-party timers to automatically repeat messages at fixed time intervals, or to PIR sensors for security applications.
