An Overview of the Product

The Model 300VSC SelecTone® Command Unit is a central control device that is capable of generating up

to four different tone signals on a line that is connected to remote speaker/ampliers in a SelecTone System.

The 300VSC can control signal lines to Federal Signal Models 300GC, 300GCX, 300X, 302GC, 302GCX,

302X, and 50GC speaker/ampliers and to other devices designed to operate with a SelecTone system. It

can also control signals to speakers designed for 25 Vrms line operation. The 300VSC has a public address

(PA) function so that voice messages or instructions can be announced over the SelecTone system through

an optional Model MSB-1 or MNC-1 microphone. The unit can also be used to play background music

generated from an external source over the SelecTone system.

Installation and Maintenance Manual

Model 300VSC-1 and Model 300VSC-1044SB SelecTone Command Units

The Model MNC-1 microphone is a hand-held, noise canceling microphone that is ideal for use as a local

microphone. The Model MSB-1 microphone is a base-station type microphone designed for desktop

operation.

The Model 300VSC-1 is intended to be installed indoors on a desktop or other at surface.

The Model 300VSC-1044B is a rack-mountable unit complete with mounting hardware. It ts any standard

19-inch rack-mount cabinet.

The Model 300VSC can be used for a variety of prioritized signaling purposes, such as playing background

music, auxiliary re 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 300VSC include

economical system expansion along with long-term system exibility.

The Model 300VSC generates and amplies tone and audio signals and applies them through signal lines

to the remote SelecTone devices in the system. The Model AM25CK Connector Kit is required in each

SelecTone device to connect the them to the signal line. Speakers designed for 25-volt operation can connect

directly to the 25-volt output. The 300VSC 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 front panel or by a contact closure at the associated remote

control input. Whenever a tone is activated, either locally or remotely, its associated front panel pushbutton

LED 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 300VSC controls are located on the front panel.

Product details and features are described in the next sections. For complete product specications, see

Table 1 on pages 8 through 10.

Chassis Dimensions and Features

The Model 300VSC-1 is assembled in a black, brushed-aluminum, two-piece housing approximately

10.50 in (26.67 cm) wide by 9.25 in (23.50 cm) deep by 2.44 in (6.2 cm) high. It is intended to be placed

on any at horizontal surface, or it can be wall-mounted using the wall mounting brackets supplied in

the accessory kit. The housing is held together with four screws: two on the bottom near the front and

two at the back near the terminal blocks.

The Model 300VSC-1044SB is assembled in a three-piece aluminum housing. The housing is painted

black and is 19.0 in wide x 10.0 in deep and 3.5 in high. This unit is installed in a standard 19-inch rack-

mount cabinet.

Front Panel Features

The front panel switches are designated as TONE 1 through TONE 4, AUX, TEST, and CANCEL. The

tone corresponding to each switch can be labeled in the white area next to the switch with a permanent

felt-tip marker. If you are changing a tone or message, remove the marking by lightly rubbing it with a

rag dampened with denatured alcohol. To avoid damaging the switches, ensure that the alcohol does not

come in contact with them.

Control Circuitry Features

The control circuitry in the 300VSC has a built-in priority-level feature. If a given tone is already

sounding when a higher priority tone is locally or remotely activated, the higher priority tone

automatically overrides the lower priority tone. However, the pushbutton LED for the lower priority

tone remains lit to indicate that the lower priority tone remains activated. When the higher priority tone

is deactivated, the LED in the pushbutton turns off and the lower priority tone resumes sounding.

Pressing the CANCEL pushbutton deactivates any currently active tones. The local microphone has the

highest priority. All of the tones have priority by number sequence and all have priority over remote PA

and background music.

Because Tone 1 has priority over all tones, the TM9 “Slow Whoop” tone module is frequently installed

in the Tone 1 position as a “Fire” signal. Whenever the 300VSC is activated and is not in the Test Mode

(see "TEST Pushbutton" below), a built-in relay opens a set of normally closed contacts and closes a set

of normally open contacts, which makes it possible to send an alarm signal to other emergency services

or circuits. Check local codes for specic requirements regarding the types of tones to use.

CANCEL Pushbutton

The CANCEL pushbutton resets all the manually activated signaling functions of the 300VSC. It also

provides a momentary dry contact closure to facilitate remote resetting of any other alarm circuit. The

contact stays closed as long as the CANCEL pushbutton is pressed. Resetting of remote activation will

not occur if the closure occurring at the remote input has not been removed.

TEST Pushbutton

The TEST pushbutton enables the testing of tones without activating speakers on the unbalanced signal

lines. During the test the tone is heard only from the monitor speaker inside the enclosure. The TEST

pushbutton also cancels false alarms. Whenever the pushbutton is pressed, the LED remains illuminated

to remind the operator to press the CANCEL pushbutton after the test is completed or the false alarm is

corrected.

Power Requirements

SHOCK HAZARD — To prevent power to the 300VSC from being turned off

accidentally, it does not have a power switch and remains energized unless

power is disconnected. Before performing any installation or maintenance,

disconnect power to the 300VSC.

The front panel has a green LED to indicate the presence of primary power. The 300VSC can be

operated from either a 120 Vac or a 24 Vdc power source. The 120 Vac power is connected via the

power cord, and the 24 Vdc power connects via the rear terminals.

Audio Inputs

A microphone can be connected directly to the 300VSC through modular jacks provided in the front

of the 300VSC. The microphone has the highest priority. There are, however, screw terminals for a

low-level, low-impedance audio signal to be input in the back of the 300VSC. The terminals enable

audio to be coupled from a PBX telephone system with the proper interface equipment supplied by the

phone company. This input is designed to also enable the direct connection of a low-impedance remote

microphone with separate PTT, which has a priority below the tones. An RCA jack in the back of the

chassis accepts a standard 1-volt audio signal from a background music source such as a radio receiver,

CD player, or a tape player.

Recommendation for the Signal Lines

REDUCED SOUND OUTPUT —If too small a diameter cable is used, unacceptable

signal voltage drop in the signal line will cause reduced sound output from the

remote signal device. Only use a cable having wire diameter greater than 22 AWG.

The signal lines transfer tone signals and verbal messages from the 300VSC to the remote SelecTone

devices. To reduce the possibility of cross talk, hum, and static-noise pickup, the signal lines must be

twisted-pair, shielded audio cable. In the majority of systems, use AWG 18 shielded twisted-pair audio

cables. Federal Signal does not recommend that new or existing telephone lines be used as signal lines in a

SelecTone system for the following reasons:

✓Interference from other services or systems, or interference from the system to other services

✓Cross talk, interference, or hum induced by other telephone lines

✓Extended downtime because of the second party involvement required to service the lines

✓The additional cost of installation, interfacing devices and monthly charges as opposed to a one-time

cost of performing the installation
