General Information

The TS959 is a microprocessor-controlled tone/speech generator that produces alarms or warning tones to
alert people of emergency conditions. It generates up to seven prioritized tones selected from an internal
library of 42 tones. (The unit can be factory-modified to extend this range to 14 prioritized tones.) With
an optional add-on speech board, the unit can generate digitally-recorded speech messages in addition to
tones.

Several user-programmable parameters are available with this unit including: the method used to activate
the tones, the duration of each tone, and the control and operation of the Volume Level Control (VLC).
These options are explained in detail in the Programming Instructions beginning on page 2.

The alarm activation inputs are priority encoded so that in the case of simultaneous alarms, only one alarm
is broadcast at a time. The priorities are established to ensure that the most important tone gains access to
the page line first. An alarm with a higher priority temporarily mutes an in-progress alarm of a lower
priority. After the higher priority alarm has been reset, the lower priority alarm is then broadcast.

The TS959 is activated by user-supplied switches or relay contacts. One switch is required for each tone.
In addition to the seven input switches, you may connect a reset switch to deactivate all seven tones. The
TS959 is equipped with circuitry to activate GAI-Tronics’ VLC devices. VLC receivers can be purchased
as add-on units for the 700 Series amplifiers. The VLC can override volume control settings, ensuring that
the alarm is heard in all areas regardless of the volume control adjustment of individual amplifiers. VLC
transmitter activation can be programmed for any or all of the alarm inputs. This feature allows only the
specified, higher priority alarms to override all volume control settings while lower priority tones do not.

WARNING

This equipment generates, uses, and can radiate radio frequency energy. If not installed and used in

accordance with the instruction manual, it may interfere with radio communications. It has been tested and
found to comply with the limits for a Class "A" computing device pursuant to Subpart J of Part 15 of the
FCC Rules, designed to provide reasonable protection against such interference when operated in a
commercial environment. Operation of this equipment in residential areas is likely to cause interference - in
which case the user, at their own expense, will be required to take the necessary measures to correct this
interference.

Do not attempt to install an older generation Model 69107-001 Speech Module from a TS958
Tone/Speech Generator into this unit—equipment damage will occur.

Programming Instructions

The TS959 is provided with default settings which can be reprogrammed to meet your needs. The
individual settings can be changed without disturbing the rest of the parameters. Make sure you follow the
necessary steps before programming the unit. After performing the actual programming, refer to the
Required Post-Programming section on page 11.

Note: If the TS959 is a new unit and has never been installed, it is generally easier to program the unit on
the bench prior to installation.

GENERAL INSTRUCTIONS

1. To begin programming, open the unit by loosening the 4 captive screws on the front cover. There are 7

programming switches, labeled SW1 through SW7, provided on the termination PC board. In addition,
a mode switch, SW8, is also provided and used during programming.

CAUTION

The unit must be powered on during programming. High voltages are present on TB1 and within
the power supply. Only qualified personnel should attempt programming this unit.

2. If the TS959 is new and has never been installed, it can be programmed on the bench:

• Connect a small 8- to 100-ohm speaker to the page terminals (TB2-25 and TB2-27).

• Connect a 3-conductor power cord to TB1-1 (black), TB1-2 (white), and the safety ground (green)

to the safety ground lug at the top or bottom of the box.

• Connect the TS959 to 115 V ac and program using the programming push-button switches.

• Set the tone level through the speaker using potentiometer R25 located near the top of the front

cover. See Figure 7 for details.

3. If the TS959 has already been installed in an operating GAI-Tronics system:

• Temporarily remove the audio connections from TB2-23, -25, and -27.

• Connect a temporary speaker (8- to 100-ohm) to the 33-ohm page audio out terminals (TB2-25 and

TB2-27). Listen to the tones and determine which are appropriate for the application while
avoiding the distraction of tones over the plant system.

• Disconnect the activation remote switches (unless they are normally open momentary switches)

from the TS959 while programming to avoid programming error. When all wiring is complete,
apply power to the unit.

EXPLANATION OF THE PROGRAMMING PROCESS

Switch (S1) is used to set the TS959 to various program modes. It is located on the back in the top left
corner of the unit. S1 is a four-position, dual in-line package (DIP) switch. The switch positions are
labeled 1, 2, 3, and 4. The bottom of the switch is labeled OPEN and is referred to as O in the following
program steps. The top of the switch is labeled CLOSED and is referred to as C in this procedure. In this
manual, the position of the four switches is represented by a row of four characters, representing the four
positions of the DIP switch from left to right. For example, the position represented by OOCO:

DIP 1 2 3 4

OOCO 0 0 1 0

=

After a programming step has been completed, S1 must be set to (OOOO). The red light emitting diodes
(LEDs) on the front panel of the TS959 indicate unit status during programming. You can document your
programming selections on the Programming Summary chart provided on page 13.

DEFAULT RESET

The Default Reset function returns the TS959 to the factory-set operating parameters. Perform the
following procedure if you want to return all the settings to their original, default conditions.

1. Set S1 to CCCC.

2. Press SW8. The LEDs on the front cover will flash through 3 sweeps. This LED sequence notifies

the programmer that the unit is resetting to the default parameters.

3. Reset S1 to OOOO, the normal operating mode.

SWITCH TYPE (ALARM ACTIVATION CONTACTS)

The TS959 is designed to accept either normally open (N.O.) or normally closed (N.C.) switch inputs
(alarm activation contacts). The unit automatically detects the type of switch being used and sets the
program parameters during this step. This step must be repeated after the rest of the programming has
been completed, and the permanent, operational alarm activation inputs are connected.

1. Set S1 to COOO. The LEDs on the front panel indicate the type of switch. Lit LEDs indicate an N.C.

switch, while unlit LEDs indicate an N.O. switch. During programming, only momentary N.O.
switches can be used, so no LEDs should be lit.

2. Press SW8. The LEDs will flash through 3 sweeps indicating that the unit has accepted the new

parameters and is storing them in memory.

3. Reset S1 to OOOO.

ACTIVATION

You may now select the way the alarm will be activated. Each of the seven alarm inputs can be set to
either momentary or maintained activation.

With momentary activation, the input switch needs to be pressed only briefly to activate the tone. It will
then sound for the programmed length of time. See the Signal Duration section.

If you want to control the duration of the alarms, select maintained activation. The tone sounds for the
length of time that the switch contact is activated. A typical application for maintained activation would be
to use a two-position switch that is manually turned ON to start the tone, and manually turned OFF to
discontinue the tone. Another application for maintained activation would be when an automatic system
controls the inputs with a relay contact. With maintained activation, the automatic system can control the
duration of the tone.

1. Set S1 to OCOO. The front panel LEDs show the existing configuration. Unlit LEDs indicate that

tone activation will be maintained. Lit LEDs indicate that tone activation will be momentary.

2. Press the switches of the tones that need to be changed until the LEDs reflect the configuration desired.

3. Press SW8. The LEDs will flash through 3 sweeps indicating that the unit has accepted the new

parameters and is storing them in memory.

4. Reset S1 to OOOO.

TONE SELECTION

You can select the desired tone for each of the seven inputs from an internal library of 42 tones. Figure 1
gives the tone names and their corresponding LED pattern. You should sample the tones as explained in
step 4 below.

Keep in mind that input 1 is the highest priority, and input 7 is the lowest. For example, if input 6 is
sounding when input 2 is activated, input 2 will interrupt. After input 2 is deactivated, or times out, tone 6
will sound again, starting from the beginning of its time duration. In this way, lower priority
announcements are not lost.

1. Set S1 to OOOC.

2. Press the programming switch of the tone that you want to program (1 to 7). The corresponding LED

will light to verify your selection.

3. Press SW8. LEDs 2 through 7 will display a pattern. See Figure 1 to identify the tone that is presently

selected.

4. Use the following switches to change tones, if desired:

• Switch 1: advances the tone number by 1

• Switch 2: advances the tone number by 10

• Switch 3: clears the tone number to 0

• Switch 4: enables the programmer to hear the tone through the speaker. Press Switch 4 a second

time to turn the tone off. If you cannot hear the tones, the volume control (potentiometer R25) may
need to be turned up. It is located to the right of S1 on the inside front cover.

Figure 1. Tone Selection Library

1. When the desired tone is identified, press SW8 to store the tone selection. The LEDs will flash

through 3 sweeps indicating that the unit has accepted the new parameters and is storing them in
memory.

2. If only one input is to be changed, proceed to step 7. If additional tones must be changed, repeat

steps 2 through 5 until all new tones have been programmed, and then proceed to step 7.

3. Reset S1 to OOOO.

SIGNAL DURATION

This step need only be completed for tones selected to have momentary activation. See the Activation
section. Tones programmed for maintained activation will continue as long as the corresponding alarm
input switch is activated. If the duration of momentary activation inputs is not programmed, the unit will
default to continuous operation. In the continuous mode, the alarm will remain “latched” after activation
until the reset switch on the front panel or an external reset switch (N.O.) connected between TB2-18 and
common (TB2-22, TB2-24, or TB2-26) is closed.

Note: Activating the reset input will clear ALL alarm activations.
The programmed time duration of an input can be determined by observing the front panel LEDs and

comparing them to Figure 2. LEDs 1, 2, and 3 represent the units of time: minutes, increments of 10
seconds, and single seconds, respectively. LEDs 4, 5, 6, and 7 represent the number (quantity) of the units
described by LEDs 1, 2, and 3.

A timed duration activation of between 1 second and 15 minutes can be programmed for each of the seven
alarm inputs. The front panel LEDs will again be used to indicate program status.

1. Set S1 to CCCO.

2. Press the switch of the input that you want to program (1 to 7). The corresponding LED lights to

verify your selection.

3. Press SW8 to determine the present duration status. To interpret the number, see Figure 2. For

example, if LEDs 5 and 6 are lit, the duration is 6 units.

Figure 2. Signal Duration Settings

1. If the duration must be changed, press switch 1, 2, or 3 to select the time unit to be changed.

• Switch 1: minutes (for durations of 1 to 15 min.)

• Switch 2: increments of 10 seconds (for durations of 10 seconds to 150 seconds)

• Switch 3: seconds (for durations of 1 to 15 seconds)

2. Now press switch 4, 5, or 6 to get the appropriate number of time units.

• Switch 4: advances the time units by 1

• Switch 5: advances the time units by 10

• Switch 6: resets the units to continuous duration

3. When the LEDs reflect the desired duration, press SW8 to store the data. The LEDs will flash

through 3 sweeps indicating that the unit has accepted the new parameters and is storing them in
memory.

4. If only one input is to be changed, proceed to step 8. If additional input time durations must be

changed, repeat steps 2 through 6 until all inputs have been programmed, and then proceed to step 8.

5. Reset S1 to OOOO.

Figure 3. Mute Attenuation

Model TS959 Tone/Speech Generator Pub. 42004-278A

MUTE ATTENUATION AND DURATION

The mute function lowers the sound volume of alarm tones and suspends speech messages. It can be
programmed to activate for a maximum of 75 seconds for a single contact closure. This prevents
emergency tones from being muted for too long. The mute function is active until either the contact closure
is removed or the programmed mute duration elapses. You may resume page override by reactivating the
contact closure which resets the mute duration time.

You may also choose “No Time-out” for the mute duration. This setting allows muting of alarm tones and
suspension of speech messages for an unlimited length of time.

The mute feature serves two functions:

1. Automatic Mute: The sound volume of generated tones is automatically reduced during each speech

message. The amount of reduction is the programmed amount for mute attenuation. The tones return
to full volume between speech messages.

2. Manual Mute: When the mute input is activated, the sound volume of tones is reduced by a

programmed amount, and pre-recorded speech messages are suspended temporarily after the in­progress message is completed. Speech messages will resume from the beginning of the message when
the mute input is deactivated. During live voice pages, tones are audible just as they are during speech
messages. This feature ensures that voice pages are heard clearly over tones and that speech messages
do not interfere with voice pages.

Note: Activation of the mute input feature is accomplished by providing a contact closure on the tone

generator’s mute input.

Additional equipment is required for Page/Party® stations to
activate the mute feature (page override). The provision for
this option is included in Centra-Page stations, and no
additional equipment is required.

The Mute attenuation function sets the muted sound volume
level for tones during the broadcast of programmed speech
messages or live voice pages. The factory default setting is

-7.0 dB. The setting can be changed as described in the
programming instructions that follow.

Eight different attenuation values are available. See Figure 3
to interpret the LED pattern corresponding to the attenuation
levels.

The value programmed for mute duration is assigned to all
tones. A contact closure between TB2-20 and common (TB2-22, -24, or -26) activates the mute function.
The default setting for mute duration is “No Time-out.” Voice pages are then made “over” the alarm tones
and speech messages.

Voice page function requires additional equipment. Consult GAI-Tronics for additional information.
