P/N MAINST-ATS111x (ML) • REV D • ISS 24JUN14    3 / 48 
•  The LED flashes quickly when a fault is detected or when 
an alarm occurs, in armed state. 
Operating features 
Keyboard backlight and night light 
The default keyboard backlight and night light settings are as 
follows: 
•  Keyboard backlight on (bright) for approximately 4¼ 
minutes following a key press. 
•  Night light on (dim). 
These functions can be changed from the RAS menu. 
LCD contrast 
The LCD contrast may be adjusted by pressing and holding the 
Menu key while momentarily pressing the Up or Down arrow 
keys to change the display contrast. The default setting is 12. 
LCD backlight 
The LCD backlight illuminates for 30 seconds following a key 
press. 
Buzzer tone 
The Buzzer tone may be adjusted by pressing and holding the 
Clear key while momentarily pressing the Up or Down arrow 
keys to change the buzzer tone. The default setting is 16. 
LCD text format 
The ATS1111/ATS1116 RAS has a 4 line x 16 character LCD 
and may display text in three alternative formats, as follows: 
•  Format 1 (default) wraps text using hyphens when a word 
is broken onto the next line. 
•  Format 2 wraps text without hyphens when a word is 
broken onto the next line. 
•  Format 3 wraps text to the next line without breaking 
words. 
To change formats, press and hold the ‘0’ (zero) key while 
momentarily pressing the Up or Down arrow keys. 
This option is not available on the ATS1110 or ATS1115 RASs 
with 2 line x 16 character LCD. 
System fault buzzer 
In case a System Fault occurs (no more communication to 
control panel) the text “System Fault” appears on the display 
and the buzzer will be activated until any key is pressed. The 
setting “Auto” is used to enable this feature for countries where 
this is a requirement. The setting can also be set to “On” or 
“Off”. The setting can be changed by holding the Menu key 
while momentarily pressing the 0 key. Each next press of the 0 
key selects either “Auto”, “On” or “Off”. 
Function keys 
•  F1 = ‘OPEN’ + 1 
•  F2 = ‘OPEN’ + 2 
•  F3 = ‘OPEN’ + 3 
•  F4 = ‘OPEN’ + 4 
•  TZ62 = ‘OPEN’ + 5 
•  TZ63 = ‘OPEN’ + 6 
Power up 
Upon initial power up, the buzzer will sound two beeps 
indicating that the internal non-volatile memory is OK. All of the 
area LEDs may illuminate, indicating that the system is armed. 
All areas must be disarmed in order to enable access to the 
installer programming menu options. 
Troubleshooting 
General faults 
No LED or LCD display: 
•  Verify the +13.8 and 0 V wire connections on both the 
RAS and the power supply. 
•  Verify power output on the DGP or external power supply. 
Area and Status LEDs are flashing and the LCD display reads 
System Fault: 
•  Verify the D+ and D− wire connections (may be reversed 
or open circuit). 
•  Verify the address DIP switches of the RAS is set to the 
proper address. 
•  Verify that the control panel or four-door DGP is polling the 
RAS address. 
ATS1115 and ATS1116 RAS with Smart Card reader does not 
respond to a Smart Card: 
•  The RAS may actually be an ATS1110 or ATS1111 type 
that is not fitted with a Smart Card reader.  
•  The Smart Card may not be programmed (blank). 
RX and TX LED Indications 
RX and TX LEDs are provided on the circuit board to assist in 
fault diagnosis, and are visible when the rear plastic cover is 
removed.  
•  Rx: The yellow Rx LED flashes to indicate polling data is 
being received on the system bus from the panel. If the 
LED does not flash, the control panel is not operational or 
the bus is faulty (usually cabling). 
•  Tx: The red Tx LED flashes to indicate the RAS is replying 
to polling from the control panel. If the Rx LED flashes but 
the Tx LED does not, the RAS is not programmed to be 
polled in the control panel or is addressed incorrectly.
