FireFly™ TFT Display

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.

All The Right Things

FireFly™ is low profile and incorporates an on-board gong and outputs for separate hall lanterns. Pre-programmed to a standard configuration with on board options means that FireFly™ is powerful but completely interchangeable, a stockable product with no need for factory re-programming. Dipswitch options include colour, layout, landscape/portrait orientation, and more.

The TFT300 Series indicators can display any two-character alpha-numeric floor designation, and are pre-loaded with a library of over 200 full screen pictogram messages as standard. Floor designations and message images are easily reconfigured on site from the Drucegrove IND55 2-Wire™ controller interface.

Lift Connectivity


The FireFly™ indicator is simple to install and is compatible with the Drucegrove 2-Wire™ System, avoiding the need for local power supplies, or expensive screened or twisted pair cables. Each comes with loop in/out terminals for easy installation in a “daisy chain” down the lift shaft. Additional branches can be added to expand the network later.

The FireFly™ can be mixed with other 2-Wire products on the same bus, including the DragonFly™ multimedia TFT displays, dot matrix and segment LED indicators, gongs, speech announcers and more.

The TFT300 Series can also be connected directly to an OTIS® lift with an RSL bus via either an OTIS® Remote Station or the Drucegrove DEC100 interface. The display will then automatically respond to Otis® floor designation characters, car direction, car overloaded and emergency messages.

Mountings, Fixings & Housings


We can supply the FireFly with a flush mount faceplate and back box, or a surface mount fixture, complete with a lens and any mountings and faceplates needed for fitting on the landings or inside your lift cars. Our in-house metalwork facilities include laser cutting, CNC bending, welding and engraving which allows us to supply the indicators ready for mounting in almost any location with a professional finish and minimal hassle.

Vandal Resistant FireFly™


The FireFly™ can be supplied in with a thicker polycarbonate lens and associated mounting brackets for spacing it off from the TFT screen to comply with category 2 of EN81-71:2005 for vandal resistance.

Drucegrove can also supply vandal resistant surface mount fixtures to meet the same specification.
