speakers designed for 25 Vrms line operation (15 W max.). The 300SCW-1 has public address (PA)
capability, allowing voice messages or instructions to be announced over the SelecTone system through an
optional Model MNC-1 microphone. The microphone is a handheld, noise-canceling microphone that is
ideal for use as a local microphone. The Command Unit can also play background music generated from an
external source over the SelecTone system.
The Model 300SCW-1 must be installed only in indoor (NEMA 1) or other protected installations. It can be
mounted on any horizontal surface using #10 screws, appropriate for the type of mounting surface material,
and the four mounting holes in the 300SCW-1 housing (see Figure 1).
The Model 300SCW-1 can be used for a variety of prioritized signaling purposes, such as playing
background music, auxiliary fire alarm, evacuation alarm, start and dismissal, paging, and other emergency
warning applications. The system can be automated if external devices such as heat detectors, switches or
program clocks are connected to the remote control inputs. Additional advantages of the Model 300SCW-1
include economical system expansion along with long-term system flexibility.
The Model 300SCW-1 generates and amplifies tone and audio signals and applies them through signal
lines to the remote SelecTone devices in the system. A Model AM25CK Connector Kit is required in
each SelecTone device to connect the SelecTone devices to the signal line. Speakers designed for 25-volt
operation can connect directly to the 25-volt output. The 300SCW-1 has provisions for up to four SelecTone
tone modules of your choice. The tones are designated as Tone 1, Tone 2, Tone 3, and Tone 4. Each tone can
be manually activated locally by its associated pushbutton switch on the control panel or by a contact closure
at the associated remote control input. Whenever a tone is activated, either locally or remotely, its associated
LED on the control panel pushbutton lights to indicate that the tone has been activated. The LED remains lit
until the tone is deactivated and the contact closure is removed. All 300SCW-1 controls are located on the
control panel.
