The AC-1100 card reader includes a tri-color LED indicator that can emit red, green or amber 
light.  The reader also has a piezo buzzer set in the resin at the rear of the unit. 

The LED and buzzer are used to indicate normal access control events and to diagnose card 
reader malfunction. 

When 12 V

dc

 power is applied to the AC-1100 reader, the LED flashes amber and the buzzer 

emits a short tone.  When successful communication with the controller is established, the LED 
continuously flashes green at one-second intervals. 

When a proximity card is successfully read by the AC-1100, the buzzer sounds. 

The status of an access control transaction is indicated by the LED; green for access allowed 
and red for access denied. 

The following table describes the various states of the LED and buzzer for assistance in the 
diagnosis of typical reader behavior: 

 

AC-1100 diagnostics 

Condition: 

LED flashing Amber 

Description: 

Some form of RS-485 scanner network problem exists. 

Possible causes: 

AC-1100 reader is not connected to the RS-485 scanner network. 

 

Cable problems such as induced noise, cable breaks, core reversal or 
ground loops between the devices. 

 

Incorrect or duplicate scanner address. 

 

No host device found on the RS-485 scanner network.  (The host may 

be switched off). 

Condition: 

LED on Amber and/or buzzer on continuously 

Description: 

Some form of power or CPU problem exists. 

Possible causes: 

The AC-1100 reader is experiencing operational problems which could 

be a result of inadequate power supply. 

 

This condition may also arise if the AC-1100 electronic circuitry is 

physically damaged. 

Condition: 

LED flashing Green 

Description: 

The AC-1100 reader is operating normally.
