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 the diagram 

 

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.
