## Summary description

Dusk-to-dawn light sensor switch FF AZ-B PLUS is a 230V, 16A automatic twilight controller with adjustable sensitivity from 2 to 1000 lux and an external probe.

## Long description

FF AZ-B PLUS dusk-to-dawn light sensor switch is an automatic 230 V twilight controller designed to switch lighting circuits based on ambient illumination. The device accepts mains supply and provides a switched output rated for 16 A, with adjustable sensitivity from 2 to 1000 lx via its external probe. The external probe allows accurate measurement of surrounding light levels while the controller can be installed in a protected electrical enclosure. Intended for stable, repeatable light-dependent switching, this unit is suitable for outdoor and indoor lighting control where automatic operation and energy savings are needed.
Advantages
The sensor switch features a wide sensitivity range (2–1000 lx) that enables precise setting for different environments, from very low twilight thresholds to daylight-level control. The external probe permits flexible mounting away from the controller for accurate exposure to ambient light and reduced influence from nearby artificial sources. Rated for 16 A at 230 V, the switch supports common lighting loads without additional relays. Mechanical and electrical design provide reliable operation for timed night/day switching and reduced manual intervention.
Suitable for
 Street lighting and pathway illumination
 Garden, yard and landscape lighting
 Signage and illuminated advertising
 Outdoor building perimeter and security lights
 Indoor installations requiring automatic dusk-to-dawn control
Key specifications
 Supply voltage: 230 V AC
 Rated switching current: 16 A
 Sensitivity range: adjustable 2–1000 lux
 External light probe for remote sensing
 Designed for automatic dusk-to-dawn switching
How to use
Install the controller in a dry, ventilated enclosure and mount the external probe in a position representative of ambient light, away from direct artificial illumination and heat sources. Connect supply and load following local wiring regulations, ensuring the switched load does not exceed the 16 A rating. Adjust the probe sensitivity to the desired lux threshold so the lighting activates and deactivates at the required ambient levels. Periodically inspect the probe for dirt or obstructions and verify settings after any changes to surrounding lighting or landscaping.
Usage recommendations
For reliable operation, place the external probe where it receives unobstructed sky exposure and is not affected by nearby lamps. Do not exceed the rated current; use an external relay or contactor for larger loads. Clean the probe window occasionally and check wiring connections during routine maintenance.
