San Francisco >> The Warriors endured quite the unique path Saturday night to open a season-long, seven-game homestand with a 115-110 win over the Detroit Pistons.

It’s not every night that a fire alarm — a false alarm — delays the start of a second quarter and orders Chase Center’s soldout crowd of 18,064 to evacuate, which roughly 20 percent of the fans were doing before the all-clear signal was given.

And it’s not every night that Steph Curry is honored for a milestone — is it? — but he became the NBA’s 26th player to cross the 25,000-point threshold during Saturday’s third quarter.

The crowd broke into an “MVP” chant as Curry knocked down four free throws in the final seconds for the Warriors’ final points, capping his 32-point homecoming and carrying over his momentum from a 4-1 road trip.

Both teams entered with 35-28 records, so it shouldn’t have been too shocking that a tight, back-and-forth affair played out on this stage.

The Warriors’ are so hot … “How hot are they?” … that not even a fire alarm could cool off their resurgence, winning and 11th time in 13 games since Jimmy Butler’s Feb. 8 arrival.

Saturday’s outcome was in doubt throughout, as much as the home crowd hoped that Curry’s step-back 3-pointer with 3:25 remaining would put the Warriors in the lead for good. It didn’t, but it was a positive sign for Curry who, up to then, had made just 4-of-15 3-point attempts yet owned 25 points.

It wasn’t until 35 seconds remaining when the Warriors secured an insurmountable lead: Jimmy Butler dished the ball to Draymond Green, who hit a 3-pointer with 35 seconds remaining for a 110-108 lead. Green made 1-of-2 free throws with 24 seconds left for a 111-108 cushion, then Cunningham dribbled past Green for a dunk with 17 seconds to go for a 111-110 game.

Butler made his own clutch bucket with 1:22 remaining, hitting a 12-foot, pull-up jumper to put the Warriors back in front. That gave him 26 points for his most yet in a Warriors’ uniform, surpassing his 25 in his Feb. 8 debut against Chicago as well as Thursday’s win at Brooklyn.

The Warriors opened the evening with a 9-0 lead, but they led just 22-20 after the first quarter, which is when the fire alarm went off and cast curious looks on everyone inside the 6-year-old, bayfront home.

Players on both teams remained on the court and loitered around their respective benches, with the Warriors ahead 22-20 after the first quarter. A message on the videoboards read (in all caps): “Attention: There has been a fire alarm reported in the building. Proceed to the nearest exit and leave the building. Do not use elevators.” As the game resumed, Chase Center’s public-address system and music went silent for about 15 minutes.

The Pistons and the Warriors then traded the lead throughout the second quarter (and the third and the fourth). Curry was scoreless for eight minutes after the false alarm; he had seven points in the first quarter to carry some momentum over from his sensational road show, which opened with a 56-point outburst in Orlando nine days earlier.

Curry was just 1-of-6 on 3-point attempts before halftime, and his teammates weren’t much better from there (4-of-20 overall).

The Warriors got outscored 32-12 in the paint in the first half.
