Product Overview

The RTDS3 Remote Time Delay Switch provides timed switching for lighting, heating, air 

conditioning and ventilation equipment, to be used with a separate switch or interfaced 

to a control system such as a building management system (BMS). Housed behind a 

vandal-resistant bare faceplate, the unit is operated by a momentary contact closure input, 

offering remote activation of the connected load whilst saving energy by switching it off 

automatically when not required (after an adjustable period). At any time, the activation 

period may be extended with a further brief contact closure, or cancelled by an extended 

closure. The unit is available with different time delay ranges (see 

Technical Specification

).

The unit is simple to install and fits a standard single-gang UK pattress or back box (20mm 

min. depth). Ideal applications include small booths or rooms, workshops, entrance halls, 

staircases, toilets, store cupboards, hired sports courts and rooms plus many more.
