2-Wire Gong


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, with an adjustable volume control.. 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.

Lift Connectivity

The IND100 series segment indicators are simple to install and are compatible with the Drucegrove 2-Wire™ System, avoiding the need for local power supplies, or expensive screened or twisted pair cables. Each indicator comes equipped with two pairs of power in/out terminals, to enable installation in a “daisy chain” connection down the lift shaft, and additional 2-Wire branches can be added to the network, from a landing or the lift car, retrospectively.

Inputs are configured, and both power and data are provided via the Drucegrove 2-Wire System, therefore a Drucegrove 2-Wire IND055 Master Interface must be ordered for each lift.

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

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.
