 Installer Options

 
The keypad will beep twice to indicate that the setting was accepted. 
 
Example:  To change the Fence Voltage to 6 kV, enter 

0 5 3 # 

 

 
The default Fence Voltage is 

7 kV

 

The energizer will only use the High Power Fence Voltage 
parameter when mains is present.  

The energizer has a  

unique algorithm for extending battery life during mains failure  
conditions and automatically controls the fence voltage. 
 

 

LOW POWER FENCE VOLTAGE 

 

 
The open circuit low power fence voltage can be changed by pressing the 

0

 key, followed by 

the 

6

 key.  Select the desired voltage from the table and press the corresponding number 

from 

0

 to 

4

 followed by the 

#

 key.  The keypad will beep twice to indicate that the new 

setting was accepted. 
 
Example:  To change the Low Power Fence Voltage to 1900 Volts, 
enter 

0 6 4 # 

 
The default Low Power Fence Voltage is 

1700 Volts

 

 

STROBE LIGHT FUNCTION 

 

 
The strobe light output can be changed by pressing the 1 key followed by the 0 key.  Select 
the desired function from the table and press the corresponding number from 0 to 1 followed 
by the # key.  The keypad will beep twice to indicate that the new setting was accepted.

The default Strobe Light Function is option 0.  The strobe light  
switches on when the alarm is activated. 
 

 

MAGNETIC SWITCH ENABLE 

 

 
The magnetic On/Off switch (under the facia of the energizer) can be enabled by pressing the 

1

 key, followed by the 

0

 key.  Select the desired state from the table and press the 

corresponding number from 

2

 to 

3

 followed by the 

#

 key.  The keypad will beep twice to 

indicate that the new setting was accepted. 
 
Example:  To enable the magnetic On/Off switch,  
enter
