J. OPTIONAL FEATURE

DOUT stands for Detector Output which is located on the lower left hand side J5 terminal strip of the SCB

(see diagram below). It is used to connect an auxiliary piece of equipment such as a control panel LED or

a relay. An important point to keep in mind is that whatever optional piece of equipment you install, it

cannot have an operating current that exceeds +5VDC.

The diagram below illustrates some basic applications that can be implemented by utilizing the DOUT lead

found at J5 on the SCB. The top application, shown to the left of the board, represents an LED that could

be mounted on a control panel setting to give the operator a visual indication of what blocks are occu-

pied. A second application pictures the coil of a relay. This relay could be used to operate a variety of

other applications by using the contact sets (DPDT relay) associated with the relay.

In the above examples the LED would be lit for the entire

time the insulated block associated with that SCB was

occupied. The same is true for the relay. The output of

the “DOUT” lead follows the condition (active/inactive)

of the “DIN” lead (when “DIN” is active “DOUT” will go

active).

I. SETTING THE JUMPER PLUGS

The jumper plugs are found on the right hand side of the SCB, location JP1 and JP2. The default (as deliv-

ered) setting has both jumpers partially covered with black plastic shorting plugs. Basic stand-alone and

integrated operation will not require movement of these plugs. The plugs are moved into different posi-

tions if approach mode, searchlight, or more advanced optional features are being used. If needed, the

plugs may be removed by carefully inserting a knife along the bottom edge of the plastic cap and gently

twisting the plastic up. Use the following chart, with corresponding examples below, to determine the cor-

rect jumper settings for your installation:

Example Description

A Standard, Default Setting - Both jumpers, JP1 & JP2, are partially covered. This is the

standard, default setting. Neither approach nor searchlight features are active.

B Appr

oach Mode Option - The JP1 plug is covered and the JP2 is uncovered. This setting

initiates the approach mode option explained on page 17 in this manual.

C Compatible Sear

chlight - The JP2 plug is covered and the JP1 plug is uncovered. This is used

only on compatible searchlight systems.

D Sear

chlight Style Target

- JP1 and JP2 are covered. This would be used if you installed a

searchlight style target using a bi-color LED and you wanted it to work in the approach mode.
