GPS Sync

GPS Sync allows the FTS 370 system to

wirelessly synchronize with other lighting

systems without regard to distance. GPS

Delay adds the flexibility to synchronize

with lighting systems from other

manufacturers by adding an adjustable

delay (0 - 3000 ms) to the flash output.

Catenary

Catenary lighting systems require three

levels (tiers) of lights. Therefore, a

minimum of three SC 370 power and

control units and associated flashheads are

required for catenary operation. Catenary

position programming is located in the

Local Tower Configuration menu. At

least one unit must be programmed for

each of the following positions: top,

middle and bottom.

Note: The catenary flash pattern is:

middle - top - bottom.

Dry Contacts

Dry contact monitoring is available

regardless of any additional method

selected to monitor the system. The

options available in the Dry Contacts

submenu are: Combined and Separate.

Selecting the Combined option allows dry

contact information from subordinate units

to be sent to System 1. The corresponding

dry contact alarm on System 1 will be

activated. This method is typically

selected when the monitoring system has a

limited number of inputs available.

Selecting the Separate option localizes the

alarm to the affected unit. Each alarm

point in the system can be monitored

individually. This is the preferred method

when using dry contacts to monitor the

system.

Photodiode Alarm Disarm

Photodiode Alarm Disarm inhibits the

system’s 19 hour mode timer from

generating a photodiode alarm. This

feature is particularly useful in areas that

are prone to periods of light or darkness

that would exceed the 19 hour mode timer.

To activate this feature, select “ON” in the

menu.

Note: The 19 hour mode timer is

intended to provide notification of a

possible failure in the system. The

disarm feature should only be activated

if the system is installed in a location

prone to conditions previously

described. Verify that the photodiode is

installed and functioning correctly

before selecting this option.

Auxiliary Input

The Auxiliary Input allows an external

device, such as a radar system, to inhibit

the output of the beacon. Control via the

Auxiliary Input is limited to systems

consisting of a single SC 370 power and

control unit. Connections for the Auxiliary

Input are discussed in Section 1 “P2

Auxiliary Input” and shown in Figures 2-

22 – 2-31. A description of each Auxiliary

Input menu option is described in the

following bullet points:

 Help provides a description of the

Auxiliary Input menu.

 Command Status indicates the current

mode (On or Off) being commanded by

the external control device.

 Control Type sets the type of input for the

external control device. Options in the

Control Type menu are: Disabled

(external control not activated), Modbus

(See Appendix A) and Dry Contact

(contact closure required to inhibit light

output).

 Confirm Output Configuration allows any

alarm contact to be “reassigned” to

indicate that the system is operating

normally while the flash is inhibited.

 Heartbeat used only when Auxiliary

Input is controlled by Modbus to

provide a fail-safe in the event of a

communications failure between the

SC 370 and the external control

device.
