The CommCenter can be used for a variety of prioritized signaling purposes, such
as indicating the status of a machine or process, background messages, evacuation,
alarm, start and dismissal, and other audible notification applications. The system
can be automated if external (customer-supplied) devices such as programmable
controllers, heat detectors, switches, or program clocks are connected to the remote
inputs. This product is not listed for fire use.
A CommCenter plays and amplifies messages through signal lines to the remote
SelecTone
®
devices in the system. To connect the SelecTone speaker/amplifier to the
signal line, a Model AM25CK Connector Kit is required in each SelecTone device.
Speakers designed for 25-volt operation can connect directly to the 25-volt output.
Each message can be activated by a contact closure or opening at its associated
remote control input. The remote control inputs can be configured to work with either
latching or momentary contacts.
Each CommCenter can accommodate up to six storage chips, selected from a
library of prerecorded voice messages, melodies, tones, and/or signals. There is one
message per storage chip. Each chip plugs into a 28-pin IC socket. The six sockets
are labeled PRIORITY TONE 1 through PRIORITY TONE 6
.
