d. Remote Area Data Collector (RADC) Components (Interior) (+20 V) (see Figure 1-8)

(1) Leda (Item 1). A PWA used to connect up to 12 additional sensors via the termination PWA to the RADC via

the AUX 0 port. The Leda operates from 12 vdc provided from the STARGATE 5000 or 1000 board or via the

keypad IAU.

(2) Mod2-II Modem (item 2) or Fiber Optic Cable (Optional) (item 3). The communications network between the

RADC and the PMC. The modem communicates at a 1200 baud rate between the RADC and the PMC.

(3) Audio Assessment Controller (Item 4).

A plug-in module used to switch between intercom and audio

assessment at the RADC.

(4) Remote Area Power Supply (Item 5). The remote area power supply associated with the interior RADC

supplies operating power to the connected sensors, stimuli, and audio assessment devices. The +20 V, 0.6 amp

power supply is used with the installed J-SIIDS sensors.

(5) Data Encryption System (Item 6) (optional unit). Provides secure data communications (encryption) for

specified PMC, RSM, and RADC communications links.

(6) Battery, 12 vdc, 7 amp hr. (Item 7). Consists of a lead acid maintenance free battery. The battery provides for

6 hours of system backup and takes 12 hours to be fully recharged once the battery has been completely drained.

(7) STARGATE 5000 (Item 8). The PWA contains the programs to monitor the status of optional devices and

process and forward this information to the PMC. The STARGATE 5000 PWA is used in the Interior RADC, and can

monitor and test up to 20 sensors.

(8) Termination Card (Item 9). A PWA that can interface 12 additional devices to the Leda PWA.
