NSTALLATION

 

The Model K-O2 is available in two versions of an industrial-strength, 18 Gauge, gray, powder-coated steel 
enclosure.  The pad-lockable, hinged-cover version is shown in Figure 1 and the removable, screw-down cover 
version is shown in

 

Figure 2.  All electronics are attached to the front cover.  There are trade ½” conduit knock-outs 

on all sides for electrical connections.  In potentially damp locations the knock-out on the bottom of the case 
should be used to minimize the possibility of water entry.  

DO NOT USE THE VENT HOLES FOR WIRE ENTRY.

 

1.

 

This unit is designed to mount to a rigid, vibration-free surface near the middle of the area to be 
monitored about 5 feet above the floor.  

2.

 

It should be located where there is free airflow - avoid corners or recesses.   

3.

 

The air vents on the sides of the enclosure should not be closer than 1 foot from the nearest 
perpendicular wall and must not be obstructed or painted-over. 

4.

 

May be mounted  

 

Vertically with the status LED in the lower left or lower right corner. 

 

Horizontally in any orientation. 

5.

 

Mounting holes are made for direct wall screws for the surface encountered. (Mounting screws not 
provided) or switch box spacing.
