Indicates an imminently dangerous condition: failure to follow
the instructions may lead to death or serious injury.
Indicates a potentially dangerous condition: failure to follow
the instructions may lead to slight injury or property damage.
Caution
● Concerning replacement parts, such as LED unit, bulb or fuse, be sure to use those specified in this manual.
● For safety, make sure to connect an external fuse to the power source as shown in the wiring example.
● Do not substitute parts of units from other products. It may cause a breakdown.

4. Installation
■ Mounting
● Drill mounting holes in the wall. (See the mounting dimension.)
● Secure the mounting bracket with the hex bolts and hex nuts.
● Install the Signal Tower vertically at a location that has sufficient strength and minimal
vibration.
● The alarm of buzzer models can be heard best from the front direction.
Therefore make sure the Signal Tower is facing the correct direction before install it.
Caution
● This product can be used only indoors. (Do not use it outdoors.)
● Do not install the Signal Tower horizontally or inverted.
(See the following "Mounting side" .)
● Make sure of the specified operating voltage and current before use.
● Do not use or keep without LED unit or Head cover installed.
● Use the soft cloth with moisture when the LED unit or Bse unit must be
cleaned up. (Do not use thinner, benzine, gasoline or oil.)
● During installation, do not remove the waterproof sheet. It may cause
a malfunction of water proof structure.
● This product has 1mm thick waterproof packing at the bottom of the pole
bracket. However, when complete waterproofing is not provided due to the
unevenness of the installation surface, apply waterproof sealant between the
unit and the installation surface to maintain waterproof conditions.

5. Wiring Procedure
■ Wiring procedure (Concerning the mark ※, the conditions about the product corresponding to UL are mentioned.)
● Please make wiring connection according to wiring example.
● For wiring of 5 layers or less, please make wiring connection by increasing or decreasing external contacts in each layer according
to wiring example.
● When using multiple LED units of the same color, make the contact capacity equal to the number of same color LED units multiplied
by the contact capacity for 1 light. (This is because LED units of the same color light up for one signal line.)
※ Fuse for protection of external contact should be installed within 305mm from the connected point of the power source wire.
● When wiring is completed, insulate the end of each unused lead wire by using insulation tape.
※ Use "Class 2 Circuit" for the power supply source. Concerning fuse and fuse-holder, be sure to use the products authorized
by UL Inc.
※ Use the fuse conforming to the rated current of the machine. ( Example : Class J type fuse )
● If you have any questions about simultaneous use of multiple units or other special operations,
contact PATLITE Customer Service before wiring.

Caution
●Never fail to observe the strip length of lead wire. Excessively short strip length causes
connection failure and excessively long strip length gives rise to electric shock or short circuit,
which are extremely dangerous.

Lead wires
① Press the lever with screw driver etc.
② Insert the stripped portion of the lead wire all the way into Terminal block.
③ Release the lever and wiring is completed.
●While wiring this product, take care to avoid short-circuits from loose wire strands or similar
conditions.
●Do not use unnecessarily strong force to separate the Terminal block and the Body.
Inside wiring may be damaged and may cause failure.
●Connect high-voltage power supply cable to the specified terminals in the Terminal block.
Failure to connect this cable correctly will burn out the internal circuit.
●When removing the lead wire, be sure to operate the lever first, before pulling the wire out.

Caution
● Make sure the power is OFF before wiring. A short circuit may damage internal circuits or cause an electric shock.
● Do not pull out the lead wire or push it into the pole or the body.
● Install the external contact fuse on the power supply side as shown in the wiring example in order to prevent
burn in case of a wiring error.
● Failure to follow wiring instructions may cause damege to product or product may not operate properly.
● Do not apply voltage directly to Flashing common wire. It may cause a breakdown. ( FB type )
● Do not connect Continuous common wire and Flashing common wire. It may damage the internal circuit.
● If using both flashing and continuous circuits, do not apply power at the same time as this may cause second color
indicator to light. This also applies to both alarm circuits.
● If you use the product with both alarms, please use external contacts for lighting and for alarms.
