■
Drill mounting holes in the wall. (See the following installation diagram.)
●
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.

● 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.
● When the cable gland is used, the hole must be the dimension that it can go
through. The cable which it can be used for is as follows;
Screw Size: M16×P1.5, Screw Length: Maximum 11mm,
Outer Diameter: Maximum 25mm, Material: Plastic.

5. Wiring Procedure
Wiring procedure
■
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 Ⅱ 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 )
※
For the 90〜250V AC model, connect the green/yellow lead wire to the ground.
※
If you have any questions about simultaneous use of multiple units or other special operations,
●
contact PATLITE Customer Service before wiring.
(Concerning the mark ※, the conditions about the product corresponding to UL are mentioned.)

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.
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.

※Use the fuse conforming to the rated current of
the machine which you install product.
(Example : UL Class J type fuse)?
※Since a maximum of 10A inrush current flows
through the power supply wires, select contacts
with enough capacity to handle the inrush current.
Caution
● Make sure the power is OFF before wiring. A short circuit may damage internal circuits or cause an electric shock.
● Do not apply voltage directly to signal wires and common wires. It may damage the circuit. ( 90～250V AC )
● 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.
