- What is a pulsed flashing beacon?
- A pulsed flashing beacon is a device where a filament lamp (tungsten filament, tungsten
halogen or Light Emitting Diodes - LED) is repetitively switched on and off.
- Where would I use a pulsed flashing beacon?
- Pulsed flashing beacons are used where a warning signal is required but which needs to
remain fairly unobtrusive (for example airport ground vehicles, machine operating) or
where a signal distinct from another is required.
- I have heard that pulsing a mains lamp can cause EMC problems, how do you combat this?
- We address this particular problem using a "zero crossing switch" which
switches the load either on or off only when the AC voltage waveform is 0 volts thus
eliminating the clicks and spikes otherwise generated.
- I want a string of lights to flash "all together" is that OK?
- YES! With the PSL upwards, "Slave" terminals are available for connecting Static Light Beacon Lamps which will flash ON at the same time as
the bulb in the Pulsed beacon. Just ensure that the total wattage of the slave units does
not exceed the
- What does B15D mean?
- B15D is the lamp cap style and is the standard unless an alternative is specified.
- What types of lamp cap do you supply?
- B15D
- Small Bayonet Cap (SBC), 15mm Diameter, Dual Pin.
- E14S
- Small Edison Screw (SES), 14mm Diameter, Single Pin.
- E27
- Edison Screw (ES), 27mm Diameter, Single Pin.
- B22D
- Bayonet Cap (BC), 22mm Diameter, Dual Pin.
- The PPH and PPJ seem very expensive compared to the PSH and PSJ, why?
- The PPH and PPJ are special products designed for long range signalling (up to 10km)
applications and incorporate lamps with in-built reflectors. These only emit a tightly
focused beam light out of the end of the beacon which is ideal for signalling across water
for example.
