Model SRC-8
Addressable 8-Output Relay Module

OPERATION

The Model SRC-8 module from Siemens
Industry, Inc., used with the SXL-EX System is
an 8-Output Programmable Relay Module that
provides eight Form C relays. Terminal Block 9
(See Figure 1 below) provides a connection to
TB3 on the Main Board for a 24V regulated and
filtered power supply. Terminal blocks 1-8
provide the eight Form C relays.

If the green LED (labeled DS1) on the right­hand side of the module is on, it indicates that
the module is active.

The SRC-8 causes a trouble on the display
panel when any of the following three conditions
occurs:

1. There is a short on the data line.

2. No SRC-8 module is connected to the
System, though there is an address for the
module in the System.

3. An SRC-8 module is connected to the
system, but there is no address for it in the
System.

(To power up, connect the AC first

and then the battery.)

In a New SXL-EX System

(Refer to Figure 2):

Install the SRC-8 in the upper right-hand
portion of the EN-SX enclosure by following the
steps listed below.

1. Insert the four 6-32 x 1/2 standoffs over the
four studs in the upper right-hand corner of
the SXL-EX enclosure as shown in Figure 2.

2. Place the SRC-8 board over the four
standoffs in the upper right-hand portion of
the EN-SX enclosure. Using the four 6-32
screws provided, fasten the SRC-8 board to
the standoffs.

In an Existing SXL® System

(Refer to Figure 3):

To place the SRC-8 on the Main Board of an
existing system, first remove the existing Display
Board and its cover by following the steps below.

1. Remove the Display Cover from the Display
Board as shown in Figure 3. Discard its top
two standoffs.

2. Unplug the ribbon cable from the Display
Board at jumper JP4 on the Main Board.

3. Remove the Display Board from the SXL
Main Board by unscrewing the four 6-32
screws and setting them to one side.

4. Remove and discard the two standoffs that
were supporting the two upper corners of
the Display Board.

5. Next, install the SRC-8 by using the four 6­32 x 1-

7

/8 standoffs, the 6-32 screw, and the

two 15/16 standoffs provided as follows:

• Fasten the 1-7/8 nylon standoff provided to

the back of the upper left-hand corner of
the SRC-8 with the screw provided.

• Remove the screw from the upper right-

hand corner of the Main board.

• Screw another long standoff to the upper

right-hand corner of the Main board.

• Screw the last two long standoffs provided

to the Main board as shown in Figure 3.

• Place the SRC-8 module on the standoffs.

• Use the screw removed from the Main

board to secure the upper right-hand
corner of the SRC-8 board to the Main
board.

6. Fasten the two short standoffs remaining to
the bottom two corners of the SRC-8 board
(They are supports for the Display Board).

7. Once the SRC-8 is in place, re-install the
Display Board by reversing Steps 1-3 above.

PROGRAMMING

Use Program Level 9 to program the System to
supervise the SRC-8 module; and refer to the
SXL-EX Manual, P/N 315-095997, Program
Level 5, for programming the relay output
control matrix.

1. To enter the System:

a. Press the RESET and DRILL keys at

the same time.

b. Enter your password (Refer to Enter

Password under PROGRAM MODE in
the Manual).

c. Press the SILENCE key to confirm the

RESET button 9 times.

b. Press SILENCE.

4. To program the SRC-8:

a. Note the top zone status LEDs on the

display board.

• If the top red LED is on, the SRC-8 is
activated and sublevel -1 appears in
the display.

• If the top red LED is off, the SRC-8 is
not activated.

b. Press the DRILL key to toggle between
