Switch description

Unit operation

The FlarmACL is powered via an external power connection (Screw terminal pin labeled Power). Its own current draw is appr. 30 mA. The device listens to any Flarm traffic (fixed baud rate of 19200 – newer versions (from July 2018) have an automatic baud rate detection from 4800 to 115200bps) on any of the three RJ45 connectors and switches on the connected strobe light via an internal solid-state switch (Screw terminal pin labeled LED).
RJ45 connectors also act as a Flarm splitter device.

Control is done via the three-position switch with an integrated LED indicator:

• Top position: Output is switched ON, LED indicator is always ON, and green
• Middle position: Output is switched OFF and disabled, LED indicator always OFF
• Bottom position: Output is switched ON, the LED indicator is ON only when an urgent alarm is detected, the target is closer than 1000m and groundspeed is present (glider is moving) and red when this happens. If no alarm is issued for 3 seconds the output is switched OFF.

Automatic triggering of FlarmACL

The FlarmACL will be automatically triggered under 2 conditions.

Condition 1:

• If the switch is set to AUTO and if any kind of farm alarm is active and the glider is moving (groundspeed)

Condition 2:

• If the switch is set to AUTO and a plane is closer than 1000m and the glider is moving (groundspeed)
