Masking the lens
Opaqueadhesivetapeissuppliedsothat

1. Connecttheexistingwiresinthewallboxtothesensorflyingleads.
(SeeWiringDirectionsatright).
• Donotallowbarewiretoshowbelowconnector.
• Thegroundwiremustbetightly grounded fortheunittooperate
properly.
2. Attachthesensortothewallbymountingitinthewallboxwiththetwo
mountingscrewsprovided.
3. Turnonpoweratthecircuitbreaker.
There is an initial warm-up period after installation.Itmaytakeuptoa
minutebeforetheloadturnsonduetoasensorwarm‑upperiodduring

thewarm‑upperiodendsifthesensordetectsmotion.
Rapid successive pressing of the ON/OFF button causes a delay in function.
Asinglepressofthebuttoncausesanimmediateresponse.Ifthebutton
ispressedagainwithin2seconds,theswitchignoresit.Waitatleasttwo
