8) Flash Pattern Settings
Warning – high-intensity light source. Avoid
looking directly at the light source for
extended periods of time.
The GNExB2 beacon can produce different flash patterns as
shown in Table 4. The flash patterns are selected by
operation of the flash setting DIP switch on the PCB, Fig 6.

9) Relay / Telephone Inputs and Settings
9.1 Power Input Terminal for AC & DC Wiring
A suitable power supply (DC or AC voltage) cable should
enter via one of the M20 entries and is to be connected to
terminal TB1 (see Fig. 7 below). This provides the beacon
with continuous power.
DC Unit option: Connect the beacon power input (+) to the
(L/+) terminal (TB1) and power input (-) to the (N/-) at
terminal (TB1).
AC Unit option: Connect the beacon input (L) to the (L/+)
terminal (TB1) and power input (N) to (N/-) also an
earth/ground input to the (E) terminal (TB1).
Please note: the earth/ground terminal of TB1 provides
termination only for an earth/ground cable. Refer to section
7.2.

9.2 Activation, Relay / Telephone Wiring Inputs and
Signal Type Header Setting (H1)
The H1 header selection configures the activation signal type.
Select H1 position marked AC for activation from an
analogue telephone external ringer output REN1 (typically
low current AC voltage around 90 to 150Vac)
Select H1 position marked DC for activation via a DC voltage
input of 10 to 60Vdc e.g. a digital PBX external ringer output
or a safety system relay output.
The activation input cables should utilise the second M20
cable entry and connect to terminal TB2.
Note: there is no polarity for this input.
Factory default H1 is set as AC for activation signal.
