2.5 Description of Terminals, Jumpers, Connectors and LEDs


Description of terminals and connectors



Button VOL, RESET, CONFIG

Short press (VOL−) − turn down the speaker volume

Long press (RESET) – restart the device in approx. 10 s

Very long press (CONFIG) − retrieve the device IP address, switch the static / dynamic IP address mode and reset the factory default values


Button VOL+, AUTODETECT

Short press (VOL+) − turn up the speaker volume

Long press (AUTODETECT) – set the default ALARM 1/2 input polarity in approx. 10 s

ETHERNET + POERJ-45 (PoE according to802.3af) LAN connector
DC IN 10–30 V terminalExternal power supply (unless PoE is available)10–30 V DC
Indicator connecting terminals + 12 V (24 V)12–24 V DC / 2× 200 mA externally supplied indicators; keep the wiring diagram.
“Connection establishing” LED connectorYellow

The LEDs are not a standard part of the delivery (available only in cable versions).
Once an external LED is connected, the on-board LED remains inactive.

“Connection established” LED connectorGreen
External microphone connector

The external microphone connection state does not change during the device operation. The current external microphone state is detected at the device start/restart only.

Speaker connectorThe speaker is connected in the standard delivery.

Induction loop connector

The induction loop is not a standard part of the delivery. It must be installed behind an non-conductive and non-magnetic cover. Polarity does not matter.
Notes:

  • If mounted behind a non-conductive and non-magnetic cover, the speaker can work as an induction loop to a limited extent.
  • The output is short-circuit proof. The output power is limited by the resistor only.




ALARM 1/2 terminal




Contact control 


N/O contact (default)


Use the configuration jumpers for setting. 

N/O contact: both the jumpers are mounted.





N/C contact

N/C contact: both the jumpers are mounted and input polarity is inverted in the software configuration in S. 4.4.2 Input Inversion.

Voltage control



Connect DC voltage of 5–48 V.

Voltage connection control: no jumper is mounted.

Disconnect DC voltage of 5–48 V.

Voltage disconnection control: no jumper is mounted and input polarity is inverted in the software configuration in S. 4.4.2 Input Inversion.

RELAY connector

2N® LiftIP 2.0 Relay extender connector

YELLOW EXTENDER (6-pin connector)

Used for 2N® Voice Alarm Station connection.



CANCEL terminal



Contact control

N/O contact (default)

Use the configuration jumpers for setting. 

N/O contact: both the jumpers are mounted.



N/C contact

N/C contact: both the jumpers are mounted and input polarity is inverted in the software configuration in Subs. 4.4.2 Input Inversion.

Voltage control



Connect DC voltage of 5–48 V.

Voltage connection control: no jumper is mounted.

Disconnect DC voltage of 5–48 V.

Voltage disconnection control: no jumper is mounted and input polarity is inverted in the software configuration in S. 4.4.2 Input Inversion.

Warning

  • Keep polarity for voltage-controlled ALARM and CANCEL buttons (see the instructions on the cover).

Caution

  • Should there be an acoustic feedback between the microphone and the speaker (echo), turn down the speaker volume.

LED (front side – during call)

ColorStatusFunctionDescription
YellowLight onEstablishing callSignals alarm call connecting process and rescue mode in progress if enabled.
GreenLight onConnection establishedSignals alarm call connection with the option to talk to the counterparty. The alarm call is confirmed, the incoming call is answered.

Yellow + green

Alternately flashingChecking call failureChecking call failure signaling Another call is signaled when it starts, see the cases above. Once the call ends, flashing is restored. An error state is terminated by alarm call confirmation (ALARM1 only) or a subsequent successful checking call.

No light

RelaxSignals the device relax state.

Note

  • The LEDs are located on the 2N® LiftIP 2.0 audio unit front side.
  • External LEDs can be connected too (Establishing connection, Connection established).
