Astra-863 ver. A

Indication unit

- Receiving notifications from the control panel via the wired interface RS-485,
- Displaying the generic state of the system based on the CONTROL PANEL or WIRELESS EXTENDER on 8 system indicators,
- Displaying the states of CONTROL PANEL logical partitions or Wireless devices registered in WIRELESS EXTENDER on 38 indicators,
- Sound signaling of incoming notifications,
- Accepting Touch Memory identifiers from the TM input and transferring them to the CONTROL PANEL.

1. Main function:
- Receiving notifications from the control device via the wired interface RS-485CONTROL DEVICE,
- Displaying the generic state of the system based on the CONTROL PANEL or WIRELESS EXTENDER on 8 system indicators,
- Displaying the states of CONTROL PANEL logical partitions or Wireless devices registered in WIRELESS EXTEND-ER on 38 indicators,
- Sound signaling of incoming notifications,
- Accepting Touch Memory identifiers from the TM input and trans-ferring them to the CONTROL PANEL.

2. Assigning of indicators to partitions or Wireless device is done from a PC through the software PKM Astra Pro in accordance with the Instructions for CONTROL PANEL.

3. IU has two independent power inputs (main and backup),

4. IU has an input for monitoring the external power sources (terminals ZONE),

5. IU has the ability to connect to the RS-485 CONTROL PANEL ring interface using Astra-A ILS short circuit isolators.

6. IU is powered by external redundant DC sources with a nominal voltage of 12 V or 24 V.
