Connections J2 and J3
J2: PWR 12 VDC supply input, COMMS positive and negative
data connection of the databus.
J3: Unlock relay (NO/C/NC). This relay is energised for the
unlock period, i.e. when L1 or L2 is flashing. See the ATS
control panel programming guide regarding this arming
station’s output controller group (programming menu 3).
LEDs
RX: LED flashes to indicate polling data is being received on
the system databus from the ATS control panel. If the LED
does not flash the control panel is not operational or the
databus is faulty (usually cabling).
TX: LED flashes to indicate RAS is replying to polling from the
ATS 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.
For details see the ATS control panel installation guide.
