WIRING
Link-up with the camera is achieved via 25` 16/5 SOOW cord terminated in a L21-20P twistlock cord cap. The cable is ran back to
the Larson Electronics DVR system (MDVR-ALG series, sold separately), located outside the hazardous location. The portable DVR
system allows operators to temporarily mount the explosion proof camera without the need for running conduit or cable. The DVR
system handles signal and provides power to the camera. The twistlock connector ensures the camera does not come unplugged
during operation.
We strongly encourage a licensed electrician install this product,in all locations especially in outdoor areas
where weatherproofing may be required. Universal voltage driver permits operation at 100V - 277V AC, 50 or 60Hz
except those factory ordered with low voltage 11V to 25V AC/DC.
Warning: Check product label for correct input voltage!
Attach supply line wires to the appropriate light fixture wires as shown
in thediagram 
Secure each pair of wires according to the diagram. Utilize a junction box or
similar device and take precautionary steps for weatherproofing all
connections if installed in a location where water may come in contact with the
unit. Ensure the unit is properly grounded and that wiring is done according to
all local and national electrical/building codes.
The EXPCMR-ALG-1080P-IC-16.7-25-L21.20-1227 explosion proof high definition analog camera from Larson Electronics is an
inspection camera that can be used for remote observation in hazardous locations. It is available in a fixed lens configuration, a 3.6mm
90° lens to capture large wide areas, and can produce an image up to 1080p resolution. The EXPCMR-ALG-1080P-IC-16.7-25-
L21.20-1227 allows operators to see visual process data from a centralized control room up. This temporary camera allows operators to
use a single cable for signal and power. Equipped with 25` SOOW cord, this portable explosion proof camera is ideal for temporary
installation for inspection, tank cleaning, and any application requiring a portable camera within hazardous locations.
MOUNTING
The EXPCMR-ALG-1080P-IC-16.7-25-L21.20-1227 explosion proof remote observation camera is typically mounted to flat
surfaces for observation. The included adjustable flat surface bracket has two set screws on the bracket, allowing operators
to loosen the mounting bracket, adjust the camera`s tilt orientation, and retighten to hold the camera in position. A single
thru-hole mounting bolt allows operators to adjust the rotation of the camera by loosening one bolt. Accessory pole mounts
and magnetic mounts are available.
Exp Cord Cap
Position device near work area for operation. Run cable to nearby power
source. Insert and twist-lock explosion-proof plug into a compatible receptacle within
the hazardous environment. See plug operation below.
PLUG OPERATION
Electrical connection between plug and compatible receptacle is accomplished
after plug fully inserts into receptacle and rotated clockwise.
1. Lift receptacle door and locate polarization on mating plug pin and
receptacle face. Insert plug straight all the way into receptacle until it
cannot go further.
2. Rotate plug clockwise limit (37º), this closes internal contacts and
completes circuit. This also mechanically locks plug into receptacle so it
cannot be pulled out.
3. To remove plug, push plug inward and turn to counterclockwise, pull plug
straight out.
NOTE: This product does NOT use a standard L21-20 plug and CANNOT be plugged into standard L21-20R receptacles.
This product is designed to pass power and signal through the plug for easy disconnects. Users MUST wire the L21-20R
receptacle to the correct voltage and utilize a BNC-ALG-SGL-XMFR signal converter on the output side. See Wiring diagram
for plug pinout.

Installation
Before installation:
• Make sure that the device is in good condition and all the assembly parts are included.
•
• Make sure that the wall or the ceiling is strong enough to withstand 3 times the weight of the camera.
•
provide the rated voltage and wattage for the camera. See the section.
During installation:
• Camera Lens: Handle the camera carefully to prevent scratching or soiling the lens. If the lens or IR
array shield becomes soiled, clean it only with approved products. See the Cleaningsection.
• Monitor impedance: Set the monitor impedance switch to 75 Ω.
• Power supply: Camera drop cable: The camera drop cable includes two connectors:
—Video BNC connector: For transmission of the video signal across a coax (75 Ω) extension cable.
—Power connector: When applying Vdc power, observe the power polarity. See the drop cable
Step 1. Mounting the camera
Typical ceiling mounting
1. Mark the location of the screws that anchor the mounting base
to the mounting surface. See the note above. If you are routing the drop cable through mounting
surface, also mark the position of the hole for the drop cable.
2. Drill holes for the screws that anchor the base to the mounting surface. The mounting hardware
provided is appropriate for most surfaces. However, depending on the surface materials, more
appropriate fasteners may be required.
3. Drill a 3/4” hole through the mounting surface for the drop cable, if necessary.
4. Route the drop cable through the hole in the mounting surface, or through the cable guide in the
mounting base, then attach the camera assembly to the surface using the appropriate fasteners.
5. Connect the camera drop cable to video and power extension cables.
6. Connect the other end of the video extension cable to a video monitoring device, such as a HD-TVI
capable DVR.
NOTE Drop cable connectors are not waterproof.
7. Connect the other end of the power extension cable to a 12 Vdc power source. Observe the polarity
of the cable shown in the photo on page 1 of this guide.
Step 2. Camera adjustments
1. Apply power to the camera.
