An electric latch control device includes a mounting member having an engaging end and a locking member pivotably mounted to the mounting member. A positioning member is pivotably connected to the mounting member and is engageable with the engaging end. A restraining member is engageable with and actuatable by a driving device securely mounted to the mounting member. When the restraining member is in a stopping position preventing pivotal movement of the locking member, the locking member is restrained by the restraining member, and a latch of a door lock is restrained in an opening of the electric latch control device. When the restraining member is in a non-stopping position not preventing pivotal movement of the locking member, the locking member is pivotable from a locking position to an unlocking position to thereby permit disengagement of the latch of the door lock from the opening.
