Traffic Lights but not as we know them!

MIH/2U and 3U Traffic Light beacons from deegee are proving a popular choice for some quite diverse applications, thanks to their robust build and excellent light output

In addition to the typical loading bay and site-traffic signalling applications, the MIH/2U and 3U, which can be supplied as either LED or filament lamp versions, are being chosen as the solution for a wider number of warning problems. Linked with the ‘Rising Bollard’ Security, which is becoming ever more popular at secure car-parking sites and Company premises, the MIH/2U is a safe and effective warning system to indicate to vehicles when it is safe to pass.

Being in traditional traffic light format, the MIH is easy to mount, and sturdy enough to withstand all weather conditions, being rated from -20oC to +55oC, and conforming to IEC Protection Class IP65.

However, MIH/3U is also being used as a level indicator to provide warnings for silo and tank-filling, linked to fill-monitoring systems.

The IP65 rating ensures the product is rugged against both water and dust, making it a good all-rounder for external and internal fitting.

Ultra-low power LED beacon ‘sees’ everything

DG Controls launches the latest addition to its deegee beacon range, the new ULP-LED beacon

ULP-LED has a full 360degree all-round and 180degree all-over viewing angle, but uses less than 1/6th of the power of the equivalent filament lamp version. Available as either a static (SB/ULP-LED) or a pulsed (PS/ULP-LED) beacon, both types are available for AC (dual voltage 115/230V) , and 12V or 24V DC voltage.

The low power consumption makes it the ideal choice where power is at a premium, or where heat output is a problem, for instance in a confined space.

Using the latest Superflux LEDs, which have a 90degree viewing angle, the ULP-LED beacon is the perfect combination of excellent light coverage and low-profile format.

ULP-LED would typically be mounted in the low profile R (SBR or PSR/ULP-LED) or S (SBS or PSS/ULP-LED) heavy-duty cast aluminium housings.

However, for a recent rail maintenance project, Inelmatic NV requested the robust W housing.

This has the same low profile lens as the R series of beacons, but mounts onto the black polycarbonate base, which has formed cable entries on each side.

The siting of the beacons meant that clearance was restricted, but at only 150mm overall height, and given the light output through the sides of the lens, the SBW/ULP-LED proved to be the ideal beacon for the contract.

An added feature of the ULP-LED is that it can be combined with a sounder module to offer a chime, mono or pulsed audible signal.

This adds only 8mm to the total height of the unit.

All of the deegee housings mentioned are rated to IEC Protection Class IP65.

Telephone activated beacons from Deegee.

Beacons which light in response to telephone ringing are being increasingly used at construction sites around the globe

 

Whilst the Deegee range includes both LED and xenon units, it is the xenon TXV/AC/230/TRA which has been selected for many of the major construction projects in Singapore, thanks to Deegee’s local distributor Sin Hai San Enterprise. Detecting the incoming AC ring signal, the TXV xenon beacon repeatedly triggers in time with the ring.

The V Housing for this product is a heavy duty polycarbonate, with a polycarbonate coloured lens.

The Deegee telephone activated beacons are available in other housings within the Deegee portfolio, including an explosion-proof LED variety.

This ultra-low current TP/DEX/LED beacon is driven entirely from the incoming ring signal, eliminating the need for an external power source.

Rated to IEC Protection Class IP66 and ATEX certified, the TP/DEX/LED is well-suited to extreme rugged Zone 1 and Zone 2 hazardous areas.

LED lamps preferred during maintenance visits

Sales of deegee brand LED Plug-In Modules have been given a boost thanks to a new contract awarded to Inelmatec N.V./ S.A., the sole distributor for the deegee brand in Belgium.

Moulded with a B15d lamp cap fitting, the LED Plug-In Modules are being used across industrial sites to upgrade tower beacons. Replacing filament lamps, the Led Plug-Ins are being selected by engineers due to the long life-time.

Only 25mm in diameter, the LED Plug-In bayonet cap can be fitted to new and existing models of Stacker Beacons, Towers and Single Beacons.

High brightness Clear, Red, Amber, or Green coloured LEDs are fitted, and all versions are protected by a clear polycarbonate lens. 230V AC, 115V AC, and 24V UC (AC or DC) are available in all listed colours, and a 12V UC variant to special order.

With an estimated running life in excess of possibly 100,000 hours, maintenance can be severely cut. Cost-savings are also achieved due to the lower current draw compared with a filament lamp*.

Further detail on this and the entire deegee range can be found at http://www.beaconlamps.com/. Details of the Inelmatec N.V/ S.A. range can be viewed at www.inelmatec.be

* 24V unit draws 83% less current when fitted with the LED Plug-In versus a standard 5W filament lamp.

Flashing beacons adopted by London Boroughs

For years public building fire alarm installers have met both technical and user perception obstacles when applying visual alarms, but DG Controls believes it has overcome these problems.

 

For years public building fire alarm installers have met both technical and user perception obstacles when applying visual alarms. DG Controls has overcome pressure group fears and concerns of epileptic attacks perceived as possible by the use of xenon strobe beacon lamps in fire alarm and evacuation systems.

Conventional rotating mirror beacons, while a preferred alternative, cause installers expensive powering problems.

Rotating beacon lamps have until now often been technically difficult to apply because of high current draw, whereas xenon strobe beacon lamps apparently overcame such problems.

The deegee model RFL rotating flashing beacon brings all the advantages of the sweeping rotating beam of light, but with a current draw below 1Amp at 24V DC, bringing it well within the scope of most fire alarm panel power supply units.
Early authorities to adopt these beacon lamps were the London Boroughs, where upgrading and initial fire installations at schools started the recognition of the advantages to both end users and installers alike.

This trend is spreading beyond the boundaries of London Boroughs to other areas of the country, where concerns over high inrush currents of good visibility synchronised flash xenon strobe beacon lamps, and perceived potential of hazards for epileptics have been overcome.

The RFL rotating flashing beacon lamp incorporates a high intensity halogen lamp and motor-driven revolving reflector.

A range of installation accessories is available, including protective cage guard and wall mounting brackets.

The beacon has a weatherproof injection-moulded housing, with a polycarbonate freznel dome lens that enhances light transmission.

Fitted with a red lens for fire installations, four other ex-stock lens colours are available.

DG Controls has been in business since 1967 and is dedicated to manufacturing high quality visual warning beacons for the fire/security industry as well as for industrial, marine, vehicle and aircraft obstruction warning applications.
