Barnet striker John O'Flynn's injury-time penalty broke 10-man Accrington Stanley's resistance to earn the Bees a 2-2 draw.
The Bees striker fired home after a foul on Jake Hyde by Dean Winnard but the result was harsh on Stanley, who took a deserved lead against their League Two rivals when Bobby Grant flicked home his 10th of the season.
Accrington had John Miles sent off in the 37th minute after he dangerously slid in for a challenge with Ismail Yakubu, before losing goalkeeper Ian Dunbavin to injury shortly before the interval.
The Bees got back into the game two minutes after the restart when an Albert Jarrett cross from the left was headed down and in by Yakubu at the far post.
But it did not last long as the 10 men of Accrington came back with a superb solo effort from Michael Symes. He outpaced the Barnet defence to get on the end of Grant's throughball before finishing low into the bottom of the net.
Symes and Jimmy Ryan came close to a third for the Reds while O'Flynn was denied by Bouzanis before his injury-time equaliser.
