Activate, as an alarm's wire (4)

I believe the answer is:

trip

(Other definitions for trip that I've seen before include "holiday" , "Outing; stumble" , "Hallucinogenic drug experience - lose one's balance" , "Device working a trap or alarm when stumbled over" , "Hallucinatory experience" .)

I've seen this clue in the Universal.
