Digital Security Controls Ltd. 09LC171 User Manual

The LC-171 has two types of indicators:  

1. LED  

2. Buzzer 

The installer can adjust both indicators operation during detection (ON or OFF) by using 

switch number “1” for the buzzer and switch number “2” for the LED.  When the LED indicator 

is ON the LED indicator will activate for 1 second each time an intrusion is detected. When the 

LED indicator is OFF the LED will not be used to indicate an intrusion has occurred. 

When the Buzzer indicator is ON the Buzzer will activate for 1.8sec each time an intrusion is 

detected. When the Buzzer indicator is OFF the buzzer will not be used to indicate an intrusion 

has occurred. (Setting the buzzer ON gives the installer the ability to have audible 

confirmation of intrusion detection during the adjustments and a walk test. After completing 

adjustments and walk testing it is recommended to switch the buzzer OFF) 

 

 

•  Place the top cover to the base and close it using the bottom screw.
