PRE-INSTALLATION
The following components must be set prior to installing the SSD-C housing enclo-
sure to the SSD-C mounting plate. Refer to Figure 4.

SSD-C Switch Location
If the SSD-C is located at the end of the wire, add the terminating resistance to the
communication wire by setting SW1 and SW2 to the ON position. This allows the
NIC-C to properly supervise the communication wires.
S2, S3, S4 Network Address Switches:
Set the three-digit HNET network address
for the SSD-C using the three ten-position rotary switches located on the board. (See
Figure 4.) Each of these addresses must be the same as the addresses assigned in
the Zeus Programming Tool. The range of allowable addresses is from 001 to 251
(leading zeros must be used).
S11, Reset Switch:
Momentarily Closed switch that when pressed will re-initialize
the SSD-C operation.
R70 LCD Trimmer Adjustment (factory set):
Turn to adjust the LCD contrast
asrequired.
If the SSD-C fails, the TROUBLE LED will flash at a fast rate, the sounder will pulse
and no push buttons will respond. The PMI detects this failure as a non-responding
module trouble condition.
