This product is designed to display and announce information with LED lighting and alarm* functions for the operation state
of major applications, such as equipment status, to indicate elapsed time, factory automation applications, waiting in line at
institutions, such as stores and banks, etc.
This product can be controlled with signal inputs to drive the Alarm and signal towers like a standard Signal Tower in the “Signal
Tower Mode”, but also has a new function, the “Smart Mode.” In the “Smart Mode”, the customer can use the binary input to
create a diverse display of light ashing controls, like a level meter, dimming or chase-light controls, etc., with the setup of
programmed data.
* Only for Flashing/Alarm Type
Please
• Connect an external fuse between the power supply circuit and the internal circuit to protect the Main Unit.
• Do not use in an environment exposed to strong radio waves or inductance noise. Failure to comply will result in
malfunction due to the inuence of noise.
• Do not use in an environment where corrosive gas is present. Possible cause of failure may occur.
• Discharge any static electricity from the body before handling static sensitive parts, such as the Micro-USB Cable. To prevent
damage from static electricity, touch hands or other body parts to metals or an earth ground to discharge the body from
static charge.

5. Wiring
WARNING
• The power supply should be turned o prior to wiring, at any cost. Failure to comply may result in electric shock.
• Be sure the wiring is correct. If an error is made in wiring, the internal circuit will be damaged and may cause a re.
• When transferring data via USB connection, do not allow the supply voltage from this product to contact with the personal
computer, or it’s peripheral devices. Failure to comply will result in product damage due to combustion or re.
- As an example, if the positive power terminal is connected to ground and the personal computer, FG (housing), which
in turn, makes a connection with this product via the USB connection, it should not be grounded because of the reverse
polarity. There are some personal computers which have the USB port connector and negative terminal of the personal
computer in contact with the FG (housing). Personal computers with such USB connections made, should have the FG
(housing) of the personal computer and the negative terminal of the USB port of the product connected. If the case is
where the personal computer has the metal part as the positive grounding of the supplied power source to the product,
the product will have a 24V potential applied to the negative terminal of the USB port of the product, thus will lead to
damage of the product by burning.
CAUTION
• Strip 9mm (±1mm) of wire insulation from the wire to insert it in the Terminal Buss. If longer than this, it may result in electric
shock or short-circuiting. (For (TN) Direct Mount/ Terminal Buss)
• Wire the product so that the lead wire does not protrude from the terminal. Failure to comply may result in electric shock or
short-circuiting. (For (TN) Direct Mount/ Terminal Buss)
• It is not necessary to connect to an external lead for tiers not used. When an extra lead is not connected, it should be
individually insulated with electrical tape or something similar. Failure to comply may result in electric shock or short-
circuiting.
• Do not pull the lead wire or push it inside the body. Failure to comply may result in product damage or short-circuiting.
• If wiring is extended beyond its factory length, a relevance in the length of the wire and wire gauge will cause a voltage
drop.
[ B Flashing/Alarm Type]
• By all means, do not apply voltage to the“Flashing/Pulse Enable Common” line (Refer to “5.1. Wiring Examples”on page 14).
Failure to comply may result in damage to the product.
[ A AC 100 - 240V Type]
• Do not apply voltage, or connect the source line to the signal line. Failure to comply may result in damage to the product.
Please
• Be sure to check for proper wiring before connecting the power.
• To counter against noise, shorten all wiring as much as possible, and use shielded wire when possible. In addition, separate
any signal lines which pass along high voltage cables or is susceptible to receive induction noises.
• If a non-voltage contact, such as a relay or switch etc., is used for the power supply line, consider inrush current capacity
when selecting the contact. Contact welding and malfunction will occur if current capacity is insucient.
Note
• Even when starting two or more units simultaneously, a lag will occur during ashing or the Alarm sound.

LA6 Signal Tower Complete Operation Manual
6. Operating Directions
This product contains a multi-function button (Refer to”3.2. Part Names and Outer Appearance” on page 7) under the Head
Cover in the upper section, which can be operated as follows:
- Alarm Sound Control: Adjustable up to four steps.
- LED Color Change: The luminescence color of each tier can be changed.
- Version Conrmation: The current version of the product can be checked.
- Product Initialization: The memory contents of the product can be cleared and returned to factory default values.
(Returns to the “Signal Tower” mode. The alarm sound pattern and the “Smart Mode” setup conditions have not changed.)
The operation of this product contains two modes; “Signal Tower” mode and “Smart Mode.” The explanation for each mode
shows fairly signicant dierences to them.
Changing between the “Signal Tower” mode and the “Smart Mode” is a simple ON/OFF input from the “Mode Change” signal
input wire.
Signal input “Mode Change” ON: Smart Mode
Signal input “Mode Change” OFF: “Signal Tower” mode
Although a continuous hold input controls the inputs, only a trigger input in the pulse trigger mode for the “Smart Mode”
turns into a one shot input. With the “Mode Change” in the OFF condition, the Multi-function button can be used for the
recombination of colors, changing the amount of alarm sounds, and other product functionalities.
6.1. “Signal Tower” mode
The “Signal Tower” mode controls operation with ON/OFF inputs from the wires currently assigned to each LED and alarm, like
our conventional Signal Towers. When short-circuiting each input to the “Flashing/Pulse Enable Common”, The LED will ash,
and an intermittent alarm sound will occur.
The “Signal Tower” mode set up can be done in our “EDITOR for LA series” software application (Visit our homepage at http://
www.patlite.com/ to download the software.).
• Setup Parameters
This mode has parameters that can be set up as shown in the following table.
Setup Index Description
LED lighting/ashing for ash per
minute(fpm) rate
Flashing rates are selectable from 30fpm, 60fpm, or
120fpm.
Alarm Tone Alarm sound muting or one tone can be selected from
11 varieties.
LED Color LED lights can be selected for ON or OFF.
• LED Input Conversion Table
For inputs 1-7, LED and Alarm ON/OFF can be entered as indicated in the “Signal Tower” mode operation example.
Table 4. “Signal Tower”mode Input Conversion Table
1 LED Tier 1 (Red)
2 LED Tier 2 (Amber)
3 LED Tier 3 (Green)
4 LED Tier 4 (Blue)
5 LED Tier 5 (White)

6.2. “Smart Mode”
There are three kind of modes, ““Time-trigger” mode”, ““Pulse-trigger” mode”, and “Single-display” mode”.
The factory default input is the “Time-trigger” mode, but there is a “Pulse-trigger” mode and “Single-display” mode, of which
each type can be changed by the setup, which means it is necessary to create the setup data and transmit it to the product with
a personal computer which has the “EDITOR for LA series” software application (Visit our homepage at http://www.patlite.com/
to download the software.) installed in it. (Refer to “7. Changing Data” on page 37 for details on how to change the data)
For details, please refer to the software help section.
The main mode has common functions for each type and has the following at this mode.
• Input 6 (“Mute”input)
The alarm sound stops when an “ON” input occurs, and mues the sound.
• Input 7 (“Clear”input)
If an input for each type is set to ON, the pattern contents which are controlling the operation will be initialized and it will return
to the rst pattern. Also, LED’s from all the tiers will go out at an “ON” input, and the alarm is also mued.
Refer to each mode for the explanation of how their “Clear” input should look.
6.2.1. “Time-trigger”mode
The “Time-trigger” mode has 63 set patterns to which the memory contains two or more patterns used as a series of wave-like
ows, etc. that can be used in groups. The “Time-trigger” mode operates in accordance with time, and the pattern transition
timing operates during this group operation. In addition, the maximum memory of 15 groups can be set up in ON/OFF
combinations, and a call is made to inputs 1-4.
Moreover, the “Time-trigger” mode for input 5 turns into a “STOP” input, and during the input, operates by either one of the
following conditions indicated below, and stops the time progress of the pattern changes.
- “STOP” input of a pattern currently on display to change to a lighted state.
- “STOP” input of a pattern currently on display to change to a ashing state.
- “STOP” input of a special pattern currently on display to change to a lighted state.
- “STOP” input of a special pattern currently on display to change to a ashing state.
The setup to select these can be performed in the “EDITOR for LA series” software application (Visit our homepage at http://
www.patlite.com/ to download the software.).
