What are DALI sensors?

Finder presents its new movement and presence detector Type 18.5D with DALI sensors (Digital Addressable Lighting Interface).

The detection of small movements makes this detector particularly well suited for applications in schools, offices and other environments where there is not necessarily high levels of movement.

A special lens has been developed to sense both normal movements and micro-movements. Normal ‘movement’ is detected over the wider area of 8 x 8 meters, while the ‘presence zone’ has increased sensitivity for the detection of small movements within a central area of 4 x 4 meters.

Specifications of the Type 18.5D movement and presence detector with DALI sensors:

• Programmable via DALI interface: possibility to connect up to 8 devices

• Three selectable functions: Comfort, Simplicity & Courtesy

• Detection area up to 64 sq.m: movement detection 8×8 m, presence detection 4×4 m

• Power supply voltage: 110 to 230 V AC (50/60Hz)

• Ambient light threshold range: 10 lx to 800 lx

• Light OFF delay: 10 s to 35 min

• Push-in terminals for quick and safe wiring

• Ceiling, false ceiling or recessed mounting

• Ambient temperature range: -10 to +50°C

The Type 18.5D integral sensor can be used in one of three selectable modes – each responding in a different way to the detection of movement and the ambient brightness.

Comfort ­ Daylight-linked constant light level control: Particularly suited for small offices, classrooms or workplaces, the energy-saving Comfort mode maintains a constant brightness level according to the movement and changes in ambient daylight by increasing or decreasing the level of artificial light accordingly.

Simplicity – ON/OFF control with early warning: Works as a simple movement detector, activating the lamps at 100% power, but provides warning of an impending shutdown with a power reduction to 50% for 20 seconds, avoiding the sudden total shutdown of lighting.

Courtesy – ON/OFF control with early warning + courtesy light level: Suitable for common areas including lobbies and corridors. If brightness level is lower than the set value, artificial light is maintained at 10% power, guaranteeing a constant minimum level of illumination. When movement is detected, the lamp power is raised to 100%. Courtesy mode also gives early warning of impending reduction from the 100% power level by reducing to 50% for 20 seconds.

With the Type 18.5D you can control up to 8 DALI ballasts. Addressing is done in ‘Broadcast’ mode, i.e. all the DALI ballasts are ‘slaves’ to execute the command received from the movement detector. The 18.5D features adjustable delay to shutdown from 10 seconds to 35 minutes; level of brightness adjustable from 10 lux to 800; power supply 110…230 VAC (50/60Hz).
