ATX3 TRANSCEIVER FOR DOGE AS1
The ATX3 transceiver is able to control up to 8 wireless sirens and to receive and manage all information
coming from the memorized sirens.
The transmitting section consists of two control inputs for the alarm, two inputs for on/off system status
signaling, and a button (P1) that transmits continuously (if pressed) the code to be memorized on the sirens
and which can be used also to modify this code, by keeping it pressed during the first power supply.
The receiving section consists of a 7 segment display, 4 signalling LED, 2 open collector outputs, 1
relay output (NC) and the P2 button.
The display will show, from 1to 8, which siren has indicated the problem.
The 3 surface mounted LEDs allow to view the type of anomaly detected on the sirens: tamper,
supervision missing and low battery level. The red led visible on the housing collects all these signals.
The tamper led is reset upon arming of control panel, while the other two led are reset when battery power
or radio transmission are restored.
If anomaly is detected on more than one siren, the display starts to cycle, displaying for 2 seconds the
number of siren, while the 3 led show the type of anomaly noticed.
Button P2 is used to access programming, memorize siren codes and exit programming. The sequence is
the following:
See the doge AS1 manual to learn about ATX3 programming.
Description of inputs
ON/OFF inputs (terminals n.3 and n.4)
Terminal n.3 Input to be connected to the ON/OFF output of the alarm control panel.
When it turns to LOW level (GND), after about 1 second there is a system ON
transmission, lasting 2 seconds.
The display indicates this condition with the letter “A” on steady.
When it returns to HIGH level after about 1 second, there is a system OFF
transmission with a duration of 2 seconds.
Terminal n.4 Input to be connected to the ON/OFF output of the alarm control panel.
When it turns to HIGH level (12 Vdc) after about 1 second, there is a system ON
transmission lasting 2 seconds.
The display indicates this condition with the letter “A” on steady.
When it returns to LOW level after about 1 second, there is a system OFF
transmission with a duration of 2 seconds.
ALARM inputs (terminal n.5 and n.6)
Terminal n.5 Input to be connected to the alarm output of the control panel.
When it turns to LOW level (GND) after about 1 second, an alarm transmission
lasting 2 seconds is sent to the sirens.
When it returns to HIGH level, after about 1 second, there is a transmission of 2
seconds which silences all the wireless sirens.
Terminal n.6 Input to be connected to the alarm output of the control panel.
When it turns to HIGH level (12 Vdc) after about 1 second, an alarm transmission
lasting 2 seconds is sent to the sirens.
When it returns to LOW level, after about 1 seconds, there is a transmission of 2
seconds which silences all the wireless sirens.
Description of outputs
Tamper Output (Terminal n.7 and n.8)
This relay output (with normally closed contact) collects all tamper indications from the memorized sirens.
When a tamper transmission arrives from one of the sirens, this output opens for 2 seconds.

MA-MR-ATX3-01-04 Manual ATX3 eng rev4 Rev.4 Page 2 of 2
The display and the tamper LED memorize and display the event.
This condition persists until the next arming of control panel or until the siren that caused it is deleted from
memory.
Supervision Output (terminal n.9)
This open collector output collects all missing of supervision signals from all memorized sirens.
If no supervision signal is received from the memorized sirens in 3 hours, there is a negative output on
terminal n.9.
The display and the spv LED display and memorize the event.
This condition persists until the problem that generated it is solved, or until the siren that caused it is
deleted from memory.
LOW BATTERY output (terminal n. 10)
This open collector output collects all “discharged battery” signals from the memorized sirens. When an
“exhausted battery” transmission arrives from one of the memorized sirens, there is a negative output on
terminal n. 10.
The display and the low battery LED display and memorize the event.
This condition persists until the discharged batteries of the siren are replaced or until the siren that caused it
is deleted from memory.
Description of buttons
Button P1
This button allows to transmit constantly a radio signal to be memorized on the outdoor sirens.
In this phase, the display shows the letter “t” flashing.
During programming it is used to delete a siren code. During power-on (first start-up) it generates a new 16-
bit code.
In this phase it displays horizontal dashes in continuous rotation.
Button P2
This allows to access programming, select the 8 zones to be memorized and to exit programming.
Description of the terminal board
Terminal n. 1 Positive power supply 13.6 Vdc
Terminal n. 2 Negative power supply GND
Terminal n. 3 ON/OFF input for negative signals
Terminal n. 4 ON/OFF input for positive signals
Terminal n. 5 ALARM input for negative signals
Terminal n.6 ALARM input for positive signals
Terminal n.7 and 8 TAMPER output (relay NC 100mA)
Terminal n.9 SUPERVISION output max 30 mA
Terminal n. 10 DISCHARGED BATTERY output max 30 mA
Description of Jumper JP1
Jumper JP1 is used to exclude the display of missing supervision by the led visible on the housing.
JP1 ON (closed) = Display enabled
JP1 OFF (open) = Display excluded
