23 PRS-CRF Call Stacker

23.1 Introduction

The Call Stacker is a small unit that records specific calls that cannot be send to all required zones because some are occupied by a higher priority call. The unit can store up to 16 calls in high-quality format with a maximum of three minutes for each call, including chimes and pre-recorded messages. Playback of a call can start while it is still being recorded. The unit can record and/or playback up to eight calls simultaneously.

More units can be added to a system in order to increase the number of recordable calls. Units can be connected to the Praesideo network at any place.

The call stacker can also be used as time shifter to avoid acoustic feedback from a loudspeaker to the active microphone. The call is recorded and broadcast after the recording has finished. The call can be pre-monitored before broadcast with the option to cancel the call. Time shifting and call stacking can be combined.

Logging of the call and all its playbacks is supported, but the recorded calls do not survive a power down and are not supervised, so the call stacker function should not be relied upon for emergency calls.
