Description of terminals and connectors
ETHERNET (PoE) | RJ-45 LAN connector (PoE 802.3af) | ||||
DC IN 10–30 V terminal | External 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. |
| |
Voltage control (inverted) | 5–48 V DC disconnection | ||||
Contact control (N/O) | N/O contact | ||||
Contact control (N/C) | N/C contact | ||||
CANCEL terminal | Voltage control | 5–48 V DC connection | Use jumpers for configuration. The jumper link is above the CANCEL 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. |
| |
Voltage control (inverted) | 5–48 V DC disconnection | ||||
Contact control (N/O) | N/O contact | ||||
Contact control (N/C) | N/C contact | ||||
Extender (6-pin connector) | Used for Voice Alarm Station connection. | ||||
Indicator connecting terminals | DC 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). | |||
“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.
| ||||
Button | BACK, 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 | |||
Button | SELECT, 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).
