Flip-Flop Operation
Two beacons can be mounted close to each other to form a
flip-flop operation, where the beacons will flash alternately.
To achieve this mode of operation, fit a pin header to the flip-
flop header pins on the electronics board, i.e. the two header
pins are shorted together, (see figure 10) on one of the two
beacons. The first flash on the beacon that has the header
fitted will be delayed by ½ second. The two beacons will then
flash alternately every ½ a second.
15) Interchangeable & Spare Parts
Warning – Hot surfaces. External surfaces
and internal components may be hot after
operation, take care when handling the
equipment.
The beacon cover is interchangeable, contact E2S Ltd for a
replacement cover available in various colours.
To change the cover, unscrew the M5 socket head screws
and remove the M5 screws, M5 spring & flat washers.
