A detection device includes a cover member adapted to support a detector assembly having a plurality of pins. A base member of the detection device is coupled to the cover member and, is adapted to accommodate a plurality of electrical terminals adapted to be engaged with the pins. The detection device includes a rotatable ring disposed on the base member and adapted to lock the cover member with respect to the base member. The detection device includes a plurality of shorting elements disposed on the rotatable ring and adapted to form a shorting contact with the electrical terminals. The rotatable ring is rotated with respect to the base member and the cover member to at least one of lock the cover member with respect to the base member and break the shorting contact, and unlock the cover member with respect to the base member and form the shorting contact.
