Den Haan Rotterdam
Den Haan Rotterdam is a family-owned company established in 1922. Started as a small tinsmith, it has
evolved into a globally respected producer of navigation lights, searchlights, air horns and a wide range of
nautical lamps made from copper and brass. By introducing products with advanced LED-technology, DHR
has safeguarded a visibly safe future for marine vessels in all weather conditions.
Den Haan Rotterdam manufactures halogen searchlights for over 30 years and are known for their robust-
ness, quality and reliability: key values for marine equipment. The RCN-series is the second generation of
DHR remote controlled type of searchlights introduced in 2011. This product range is very popular, because
of its compact size and its simplicity in installation and operation. The RCN-series includes various types of
light sources, such as: halogen bulbs, sealed beams and metal halide bulbs. Also the optical performance
is top-notch, thanks to the use of silverplated mirror reflectors in the 260 & 350 models.
The application of the 260- and 350-series searchlights is limitless. Mostly they are benificial for work boats,
tugs, fishing vessels, dredgers and even watch towers for land based solutions.

1. MOUNTING INSTRUCTIONS
Mounting the panel
Place the control panel inside the wheelhouse, where it is protected against weather influences. The housing
is especially constructed to be flush mounted in an instrument cabinet according the illustration on the right.
The minimum space needed behind the panel is 110 mm. (depth)
97 ± 1 mm
97 ± 1 mm
Cut-out panel
Searchlight installation
Install the searchlight in a horizontal upright position with sufficient space around the head of the searchlight
to ensure it can move freely. The dimensions can be found on page 9.

• The permissible torque should be 8 Nm
• Use only A4-grade stainless steel
Caution!
Even though the housing is made of corrosion resistant materials, galvanic corrosion may still occur. To
prevent galvanic corrosion use the supplied insulation sleeves to isolate the aluminium housing from
other metal parts.

Electrical installation
Install the electrical wiring according to the wiring diagrams showed on pages 11 - 14. Keep the distance
between the power supply and halogen lamp as short as possible. Long wires will increase a voltage drop
near the halogen lamp, which affects the light output.
Cable glands
ØD
Cable
• Prefered diameter D is 7 - 12 mm
• Material: Neoprene H07RN-F
Cable too tight!
This gives unwanted stress at the sealing of the
cable gland and water ingress will occur.
Include cable slack at the entering
point of the cable gland
Replacing cable gland
• Use gasket between housing
and cable gland
• Tighten firmly (6Nm) with
wrench
Remove the plug before placing the cable.
If no cable is connected, leave the plug in place!
Note
The cable glands on the searchlight prevent water ingress. Do not use (electrical) tape to cover the
cable where it enters the cable gland as this will cause water ingress. Do not use a rubber or shrink-
able cover on the cable gland to improve water tightness.

6. MAINTENANCE AND CORRECT USE
Tips for correct use
• Do not overheat the searchlight - max. burning time 20 min.
• Switch off the searchlight immediately after use, this increases the life
expectancy of the bulb
• Do not light-up objects closer than 2 metres
• Clean the searchlight regularly with water
• Do not point the light beam at the eyes of humans or animals
Preventive maintenance
Clean the searchlight with clean water regularly. Do not use any aggressive cleaning agents. At least twice
a year rub the dirt wiper, on top of the motor housing (see drawing below), in with silicone grease.
Safety notes
• Handle with care
