Note

: Be sure to order the correct model and frequency to avoid receiving the 

incorrect item.  
 

Mounting/Positioning Outdoor sensor 

 

First:

 Place the outdoor sensor in the desired shaded location and the projection alarm in 

the home. Wait approximately 1 hour before permanently mounting the outdoor sensor to 
ensure that there is proper reception.  
 
POSITION 

 

Mount outdoor temperature outdoor sensors 

vertically

.  

 

Protect the outdoor sensor from standing rain or snow and from the overhead sun, 
which can cause it to read incorrectly.  

 

Mounting under an eave or deck rail works well. 

 

If you choose, you can construct a small roof or box for the outdoor sensor. Be sure a 
box has vents. 

 

Mount the outdoor sensor on the North side where to prevent sun from causing 
incorrect readings.  

 

Mount at least 6 feet in the air for a strong RF (radio frequency) signal. 

 

Outdoor sensors are water resistant, not waterproof.  

 

Avoid more than one wall between the outdoor sensor and the projection alarm. 

 

The maximum transmitting range in open air is over 330 feet (100 meters).  

 

Obstacles such as walls, windows, stucco, concrete and large metal objects can 
reduce the range.  

 

Do not mount near electrical wires, transmitting antennas or other items that will 

interfere 

with the signal. 

 

RF (radio frequency) signals do not travel well through moisture or dirt. 

 

Do not mount the outdoor sensor on a metal fence. This significantly reduces the 
effective

 range

. 

 
MOUNT 

Option 1: 

 

Install one mounting screw (not included) into a wall. 

 

Place the outdoor sensor onto the screw (hanging hole on the backside). 

 

Gently pull down to lock the screw in place.  

 
Option 2:    

 

Insert the mounting screw through the front of the outdoor sensor and into the wall.  

 

Tighten the screw to snug (do not over tighten).
