Description of Terminals, Jumpers and Connectors

Description of terminals  

 

Note

  • You can access the terminals without removing the cover.

Description of terminals and connectors

ETHERNET (PoE)RJ-45 LAN connector (PoE 802.3af)
DC IN 10–30 V terminalExternal power supply (unless PoE is available)DC 10–30 V 0.5 A 

 

 

 

 

 

ALARM terminal

Voltage control

5–48 V DC connection

Use jumpers for configuration. The jumper link is below the ALARM terminal.

Voltage connection control: no jumper mounted.

Voltage disconnection control: right jumper mounted.

N/O contact: all jumpers mounted.

N/C contact: left and middle jumpers mounted.

Used for Voice Alarm Station connection.

Indicator connecting terminalsDC 12–24 V / 2× 200 mA externally supplied indicators; keep the wiring diagram.

“Establishing connection” LED connector

Yellow

The LEDs are not included in the standard delivery (excluding the cable version).
By connecting an external LED you will not deactivate the LED on the board.

“Connection established” LED connector

Green

External microphone connector

When an external electret microphone (supplied upon request) is connected, the in-built microphone will be disconnected automatically.

Speaker connector

The speaker is connected in the standard delivery.

Induction loop connector

(optional)

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

  • If mounted behind a non-conductive and non-magnetic cover, the speaker itself works as an induction loop.
  • The output is short-circuit resistant. The output power is limited by a resistor.
ButtonBACK, RESET, VOL -

Short press (BACK) – quit the system voice menu

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

During a call (VOL -) – decrease the speaker volume

ButtonSELECT, MENU, VOL +

Short press (SELECT) – confirm a selection in the system voice menu (Enter)

Long press (MENU) – enter the system voice menu

During a call (VOL +) – increase the speaker volume

Warning

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

 

Caution

  • You are recommended to turn down the speaker volume to minimise the microphone-speaker feedback (echo).
