SECTION 2 - GENERAL
The RCL-50 LED was specially designed for mariners who require a high
intensity remote controlled searchlight that can stand up to the tough marine
environment.
The RCL-50 LED 12/24V searchlight system contains a narrow beam searchlight
that produces approximately 100,000 peak candle power using a power efficient
LED module.
All functions of the searchlight can be electrically operated by remote control
from the pilot area of the vessel using the URP-102 Point Pad™, URC-103
Master Controller, and interconnect cable supplied with the RCL-50 LED.
Searchlights equipped with the URC-103 Master Controller have ACR’s unique
XRCiZ™feature. The XRCiZ™feature routinely automatically operates all
moving parts in the searchlight to keep the motors and drive mechanism freely
running.
SECTION 3 - SEARCHLIGHT
The sleek design and modern construction of the searchlight body makes it
attractive for recreational and commercial vessels. The searchlight is totally
enclosed and is made of rugged aluminum alloy. It is gasketed and finished to
be resistant to the weather.
Mounting
Make sure the area is clean and dry. The searchlight can be mounted where
desired, using appropriate length 3/16" diameter, stainless steel fasteners. Four
(4) nylon shoulder washers are supplied with the RCL-50 LED searchlight. The
nylon washers prevent a galvanic reaction between the mounting hardware and
the base of the searchlight. Be sure these washers have been inserted in the
base mounting holes and that the mounting base gasket is securely in place
before bolting down. Silicone grease should be applied to the bottom of the
gasket to help in waterproofing the unit. When mounting, be sure that the
searchlight is able to rotate 360° without hitting any obstructions. For the drilling
hole pattern, refer to the searchlight mounting template, supplied in the mounting
templates.
CAUTION: Do not mount the searchlight upside down. Moisture will not be
able to drain from the inverted light head assembly.
NOTE: The searchlight should be left uncovered if the XRCiZ™ feature is
enabled.

SECTION 4 - REMOTE CONTROL SYSTEM
The Remote Control System consists of the URC-103 Master Controller and the
URP-102 Point Pad™. This system is compatible with 12 VDC and 24 VDC
systems without modification. The remote control system may be used with 12
V or 24 V searchlights.
SECTION 5 - URP-102 POINT PAD™
Case Options
The URP-102 Point Pad™ is supplied as a surface mount unit (see Figure 4). A
flush mount option is provided (see Figure 5). To switch mounting options,
unscrew the six (6) screws on the unit’s back plate and remove the front cover.
Fit the Point Pad™ with the flush mount cover, replace the back plate, and screw
the unit back together.
Mounting
Both the surface mount and flush mount options require access to the backside
of the mounting location. Make sure there are no obstructions behind the area
where the switch is to be located (e.g. bulkheads, wires, plumbing, or hardware).
Check in advance that the coax cable from the master controller can be routed
to this location. Generally, the Point Pad™ should be mounted in a protected
area.
Install the surface mount Point Pad™ by drilling three (3) holes in the dashboard
location using the Point Pad™ surface mount template supplied. Mount the Point
Pad™ to the dashboard using the gasket, washers, and nuts supplied. Use a
sealant around the bolt holes to protect from moisture intrusion.
When the flush mount option is selected, cut a rectangular hole in the dashboard
location using the point pad™ flush mount template supplied in the mounting
templates. Use the gasket, washers, nuts, and the two U-clamps provided to
secure the Point Pad™. Use a sealant around the cut out to protect from
moisture intrusion.
Connecting to the Master Controller
The Point Pad™ communicates with the Master Controller via standard
television type RG-59 coaxial cable. The connectors are standard "F" type
television connectors. The connector on the back of the Point Pad™ is located
in the center of the panel for ease of installation. After the coax cable has been
routed and the “F” connectors attached to the coax cable, simply screw the “F”
connectors to the Master Controller and the Point Pad™. The cable and
connectors are available either through ACR Electronics or other sources of
electronic hardware.

6
Additional Point Pads™ (up to three (3) pads) may be used with one (1) Master
Controller. A standard "T" connector or RG-59 television type "splitter" is used
for each additional Point Pad(see Figure 2). Limit the total length of all coax
cable used to 300 feet.
The URP-102 Point Pad™ is backwards compatible with all RCL-100/50
searchlights and with the URC-101 Master Controller.
CAUTION: The URP-102 Point Pad™ is not recommended for use with the
first generation URC-100 Master Controllers.

Mounting
The Master Controller can be mounted in any position near the searchlight that
is protected from the weather. Check in advance that the coax cable from the
Point Pad™ and the wiring harness from the searchlight can be routed to this
location. Mount the Master Controller with the wires and coax facing down. Use
an appropriate fastener for your mounting location. Use a sealant in fastener
holes to prevent moisture intrusion.
General wiring scheme
The RCL-50 LED has a unique wiring scheme. Special attention must be paid to
the following chart. The Master Controller is supplied with an in-line fuse-holder
on the orange power lead. Use only 5 amp fuses in this fuse-holder. See Figure
7 for the master controller wiring diagram.
WARNING: Failure to follow this arrangement may damage components.

WARNING: The ORANGE wire MUST be fused with a 5 amp fuse in the
Master Controller's in-line fuse-holder.
Wiring to Searchlight
The RCL-50 LED searchlight is supplied with a 15 foot integral wire harness. If
you must lengthen the wire harness, use the same gauge wire to minimize the
voltage drop. This is especially important for the ORANGE lamp power (+) and
BLUE lamp ground (-) wires.
Following the wiring scheme shown in Table 1 use the supplied butt connectors
to connect the master controller to the searchlight.
Wiring to Point Pad™
The RG-59 coax cable is supplied without the “F” connectors attached for ease
of routing. After the coax has been routed, strip the insulation and crimp the “F”
connectors in place. Screw the “F” connectors to the master controller and the
Point Pad™.
Wiring to Power Supply
The power source must be a fused 12 VDC, 5-amp supply or 24 VDC, 5-amp
supply. Following the wiring scheme in Table 1, use the supplied butt connectors
to connect the Master Controller to the power source. Refer to Table 2 for proper
wire size for connection of the input power lines.
CAUTION: observe polarities when attaching wires!
Table 2
Function
The URC-103 Master Controller is designed to perform up to six different duties
on searchlights, winches, and other electrical devices. The Master Controller
provides optimum voltage to ensure brightest performance and long lamp life,
regardless of boat system voltage fluctuations. The Master Controller is
compatible with devices requiring 12 VDC or 24 VDC operation.

The URC-103 Master Controller has the unique XRCiZ™ feature. The XRCiZ™
feature routinely operates all moving parts in the searchlight to keep the motors
and drive mechanism freely running. Once activated, and every 30 days
thereafter, the XRCiZ™ feature wakes up and operates the searchlight. The
searchlight will rotate 360in both directions and the reflectors will move to the
full up and down positions. This feature keeps the searchlight in peak working
order when not in service for long periods of time.
To activate the XRCiZ™ feature, press and hold the Point Pad™ on/off button
for greater than 5 seconds. The green LED on the URP-102 Point Pad™
indicates that the XRCiZ™ feature is enabled. While enabled, the XRCiZ™
feature can be started outside of its 30-day cycle by pressing and holding the
speed button on the Point Pad™ for greater than 5 seconds.
While the XRCiZ™ feature is operating the searchlight, pressing any Point Pad™
button will stop the current cycle and leave the searchlight to follow any
additional commands.
To deactivate the XRCiZ™ feature, press and hold the Point Pad™ on/off button
for greater than 5 seconds. The red LED on the URP-102 Point Pad™ indicates
that the XRCiZ™ feature is disabled.
NOTE: The searchlight should not be covered while the XRCiZ™ feature is
enabled.
The URC-103 Master Controller also has a searchlight motor timeout feature. If
a Point Pad™ rotation switch (right or left) is continuously engaged for more than
50 seconds, the Master Controller will interrupt the operation until the Point
Pad™ switch is disengaged. This feature will save the searchlight motor from
burnout due to accidental activation. The elevation motor has similar features
which will timeout in approximately 20 seconds.
