The Drucegrove 2-Wire™ System is brilliant in its simplicity. Our range of 2-Wire™ lift indicators, gongs, hall lanterns and speech units are the only range on the market to eliminate the need for more than two expensive screened or twisted pair cables.
The system’s 2-Wire™ Master Controller Interfaces operate on a unique patented 2-Wire™ bus system, supplying both the power and the data signals using only two standard cables. This dramatically reduces the cost of labour and materials for new installations or refurbishment contracts.
Our Master Controller Interfaces are normally mounted with the lift controller in the machine room. All 2-Wire™ products come equipped with two pairs of power in/out terminals, to enable installation in a “daisy chain” connection down the lift shaft. Additional 2-Wire™ branches can be added to the network, on the lift car or the landing, retrospectively.
We offer a wide range of 2-Wire™ products, including:
DragonFly™ - Multimedia TFT Displays
The Drucegrove DragonFly™ TFT displays are capable of showing lift position, direction and emergency messages like the FireFly™, but with additional capability to use any combination of colours and fonts, and show additional text and images. This allows the displays to be branded and customised match the bulding they are installed in. The additional text and images can be static (ie building name, company logo, etc), or dynamic based on the position of the lift (ie individual floor tenancy information). The TFT400 Series displays are self contained units with the display and driving electronics integrated into one package. The screen sizes available are either 5.7” or 7.0”, and they have the same built in message image library as the FireFly™ TFT300 Series indicators.
For larger DragonFly™ displays, the TFT500 Omni Driver can be used. This is based on the same driving electronics as the TFT400 series but boasts a more powerful processor with graphics accelerating and video decoding hardware, and a DVI / HDMI output. Drucegrove supply a separate open frame TFT screen and a HDMI to DVI cable for connecting the screen to the TFT500 Omni Driver. The screen sizes available range from 10.4” to 42”, in 4:3 standard, 16:9 wide or 4:1 panoramic aspect ratios.
The TFT400 Series and TFT500 Omni Driver can be networked via Ethernet, which opens up the possibility of streaming live news headlines, weather, finance information, transport information (TfL, Nation Rail, bus times etc) and more from RSS feeds.
Live video can also be displayed on displays driven from the TFT500 Omni Driver. The video is streamed digitally to the display over Ethernet from either an IPTV source or an IP CCTV camera – either of which can be located anywhere in the building. Being digital, a single video feed can be streamed to an unlimited number of displays without loss of quality or the need for boosters or amplifiers.
FireFly™ - TFT Position Indicators
The Drucegrove FireFly™ TFT displays are lean, with no unnecessary or expensive gimmicks. It is designed as an entry level TFT lift position indicator, but comes pre-loaded with a host of features. With only one powerful program, ordering is simple and it is a stockable and interchangeable item.
The standard universal FireFly™ program offers 8 colour options, 16 layout options and a landscape / portrait orientation option selectable on the fly via on board dipswitches.
Every TFT300 Series indicator has the standard Drucegrove message image library built in. This library contains 195 full screen pictogram based images, each identified by a three digit image code. Image codes can be easily assigned to discrete message input on the Drucegrove IND55 2-Wire™ controller interface, which can be reconfigured on site without the need for special tools or hardware. This same image library is available on the DragonFly™ TFT displays, making it possible to mix FireFly™ and DragonFly™ displays on a single lift.
Where more advanced features can be justified,
progress to the DragonFly™ range.
LED Segment Position Indicators
The Drucegrove IND100 series of segment position indicators are available in red, green, blue or white, and as either 2, 3 or 4 character 2.2” displays with or without a direction arrow. Smaller 0.5” and 1.0” 2 character displays are also available. The segment lift indicators are specially designed to operate with the Drucegrove 2-Wire™ system and eliminate the need for more than two expensive screened or twisted pair cables for their installation.
2-Wire Speech Unit
The Digitalker® lift speech announcer is the voice of the lift industry and speaks volumes about the quality of Drucegrove products. Our SPC026 lift speech unit is available to connect directly to the 2-Wire™ bus and announce pre-programmed messages in a high quality natural voice using a digital playback system. Digitally mastered – all Drucegrove speech announcements are recorded by professional voice artists in a professional studio.
LED Dot Matrix Position Indicators
The Drucegrove IND050 series of dot matrix indicators are available in red, green, blue or white, and as either 2, 3 or 4 character 30mm or 50mm displays. The dot matrix lift indicators are specially designed to operate with the Drucegrove 2-Wire™ system and eliminate the need for more than two expensive screened or twisted pair cables for their installation.
The Drucegrove GNG023 Multi-Tone Electronic Gong announces the arrival of the lift car with a pleasant sounding single chime for up, and dual tone for down. Equipped with the useful ‘hush mode’ as standard, the gong can be triggered to operate at a reduced volume during the night. It provides high quality sound in a compact and versatile package.
Indicators that suit your needs
Drucegrove has a range of lift indicators to suit any job. With reliability and ease of installation in mind from the outset you’ll find them all over the world.
Simple Dot-Matrix Indicators come multiple colours. Where space is tight use our patented 2-Wire system. It only needs two simple wires for all the power and data for an entire shaft. They work as a family so you can ‘mix and match’ equipment on a shaft. The smart 2-Wire mother board encodes data from the main controller and lets you to manage floor positions and messages without returning equipment to us for reprogramming. This saves time. Our indicators suit any job, they’re programmed the same so you can stock them and swap them over.
Where you want us to we offer ‘stand alone’ versions programmed to suit the job. These take
• Wire Per Floor
• Inverse Binary (can suit Kone® controllers)
• Grey Code (can suit Schindler® controllers)
