Q

I want to use the signal tower light products by applying voltage to each one. Could you explain the wiring method?Tower Lamp

A

1. DC type: Separate power supply method.
-Apply (+) or (-) power to the common line (black) and directly apply the opposite polarity to the remaining color wires. The polarity of the common line and the remaining power wires must be different.
2. AC type: Consists of two power lines and one common line, and the configuration may vary depending on the number of beacon lights.
-Apply AC power to the 0.75SQ (black, white) wires, and connect the 0.3SQ black wire to the cable.
-If you wish to use the same wiring method as the DC type, please specify "DC Voltage for Each Terminal" when placing your order.

Q

Please let me know the types of signal tower light mounting bases and how to mount them.Tower Lamp

A

Types of mounting bases for tower lights:

1. SCREW & NUT: Qlight standard option. It has a threaded pole end, and a nut is attached for mounting.
2. LB□□: A standard pole mounting product with an "L-shaped" mounting bracket used for mounting the product on vertical surfaces like walls.
3. SZ□□: A round mounting base used for horizontal surface installation. Made of aluminum and silver in color.
- QZ□□: Similar to SZ□□ but made of PC and black in color.
4. LW□□: A premium vertical mounting bracket used for mounting on vertical surfaces like walls. The cable can be drawn out from the bottom of the pole, and the bottom of the pole is threaded to allow the attachment of a cable connector for flexible conduits.
For other mounting brackets, please check our website:
5. SL□□: This is a round mounting bracket used for installing the product on a horizontal surface, and it can be adjusted 180 degrees from the ground.
- QL□□: This bracket serves the same purpose as the SL□□ but is made of PC material and is black in color.

Q

What is the difference between NPN and PNP in the signal tower light wiring method?Tower Lamp

A

The basic specifications for DC lighting include a built-in bridge circuit for non-polarized wiring, allowing compatibility regardless of NPN or PNP types.

However, for DC flashing types and AC products, please check compatibility with the transistor (TR) type you intend to use by referring the manual or contacting us or a distributor.

▶ Example of DC Voltage for Each Terminal
1) NPN Transistor
-If the COM (black wire) is connected to the (+) polarity, the transistor (TR) connected to the other signal lines must use NPN, with the emitter terminal connected to the (-) power.
2) PNP Transistor
-If the COM (black wire) is connected to the (-) polarity, the transistor (TR) connected to the other signal lines must use PNP, with the emitter terminal connected to the (+) power.
3) NPN and PNP Transistors types are used depending on the polarity of the power applied to the common line.

Q

Can the length of the signal tower light be customized?Tower Lamp

A

Yes, the length of tower lights can be customized.

1. Fixed total length adjustment: The total length can be specified when ordering as an optional feature.

2. Flexible length: If you require flexible length of tower light, a double-layer pipe option is available. Please ask this option if necessary.

Q

I connected the flashing common wire to the ST80BF-3-110-RAG for flashing operation, but it is steady mode only. How can I use it as a flashing mode?Tower Lamp

A

Instructions on power supply and wiring:
1. Power supply:
- Power is supplied through the power wire.
2. Flashing operation:
- By connecting the common signal wire (black) to the signal wire, the lamp operates in flashing mode.
3. Check wiring diagram:
- Enter the product name in the search bar on our website to check the wiring diagram. The user manual can also be downloaded from the product page.

Q

What is the permissible voltage range for DC beacon light products?Signal Beacons & Sounders

A

The allowable voltage range of Qlight products may vary by product, but generally, they can be used within a ±10% range.

Q

I purchased an LF type beacon light. Can I change it to a lighting type for my own use?Signal Beacons & Sounders

A

Yes, it can. "LF" indicates the "flashing" function for LED beacon lights. If you wish to change an "LF" product to use the "L" signal, you need to open the lamp lens and adjust the internal switch.

Q

Can I listen to the sound of the buzzer?Signal Beacons & Sounders

A

You can check thel sound tones on our website:
▶ Go to "Customer Support > Technical Information > Sound" [Detail View]

Q

Can the sound of the buzzer product be adjusted?Signal Beacons & Sounders

A

Our products are designed to allow volume control. However, attaching an external volume controller may cause water and dust intrusion, potentially reducing the product's lifespan. Most buzzer products can be adjusted, but some models cannot be adjusted for volume. Please inquire when purchasing.
