Method and apparatus for installing alarm systems and door locks
A method and apparatus for marking positions for burglar alarm sensor elements on a door, the door attached to a frame having a header including comprising the steps of providing a marking apparatus the marking apparatus including an arm arm, a positioning member with a longitudinal centerline attached to the arm, and punch point attached to the positioning member, the punch point being aligned with the longitudinal centerline of the positioning member; at least partially opening the door; placing the positioning member in a hole in the header and closing the door; while the door is closed causing the positioning member to make a mark on the top of the door; and opening the door and removing the positioning member from the hole in the header; and causing an opening to be made in the door at the location of the mark.
1. A method of installing a latch or door plate on a door frame attached to a door, comprising the steps of:
(a) providing a positioning member, the positioning member having a centerline and a marking point, the marking point being aligned with the centerline of the positioning member;
(b) partially opening the door;
(c) placing the positioning member in an opening in the door;
(d) while the positioning member is in the opening, closing the door in the door frame;
(e) while the door is closed in the door frame, applying force on the positioning member to cause the marking point of the positioning member to make a positioning mark on the frame;
(f) after step “e”, opening the door and removing the positioning member from the opening in the door; and
(g) after step “e”, using the mark made in step “e” as a basis for installing the latch or door plate on the frame.
2. The method of claim 1 , wherein before step “e” a marking material is placed on the door frame to assist in seeing, and during step “e” the positioning mark is made on the marking material.
3. The method of claim 2 , wherein after step “e” the marking material is removed from the door frame.
4. The method of claim 2 , wherein the marking material is tape.
5. The method of claim 2 , wherein the marking material is comprised of a different material from the door frame.
6. The method of claim 1 , wherein in step “c” the opening in the door is one of a plurality of openings for receiving screws which will be used to connect a door locking member to the door.
7. The method of claim 6 , wherein the positioning member has a diameter and the diameter is less than the diameter of the screws used to attach the door locking member to the door.
8. The method of claim 1 , further comprising the steps of:
(h) providing a second positioning member, the positioning member having a centerline and a marking point, the marking point being aligned with the centerline of the positioning member;
(i) partially opening the door;
(j) placing the second positioning member in a second opening in the door;
(k) while the second positioning member is in the second opening, closing the door in the door frame;
(l) while the door is closed in the door frame, applying force on the second positioning member to cause the marking point of the second positioning member to make a second positioning mark on the frame;
(m) after step “l”, opening the door and removing the second positioning member from the second opening in the door; and
(n) after step “l”, using the second mark made in step “l” and the mark made in step “e” as a basis for installing the latch or door plate on the frame.
9. The method of claim 8 , wherein before step “l” a marking material is placed on the door frame to assist in seeing, and during step “l” the positioning mark is made on the marking material.
10. The method of claim 9 , wherein after step “n” the marking material is removed from the door frame.
11. The method of claim 9 , wherein the marking material is tape.
12. The method of claim 8 , wherein in step “j” the second opening in the door is one of a plurality of openings for receiving screws which will be used to connect a door locking member to the door.
13. The method of claim 12 , wherein the second positioning member has a second diameter and the second diameter is less than the diameter of the screws used to attach the door locking member to the door.
14. The method of claim 8 , wherein in step “g” a first hole is drilled into the frame at the location of the mark made in step “e”, and in step “n” a second hole is drilled into the frame at the location of the second mark made in step “n”.
15. The method of claim 8 , wherein in step “g” a first hole is drilled into the frame at a first location spaced apart from the mark made in step “e”, in step “n” a second hole is drilled into the frame at a second location spaced apart from the second mark made in step “n”, and no openings are drilled in the mark and second mark.
16. The method of claim 15 , wherein the spacing apart between the first opening and the mark, and the spacing between the second opening and the second mark are the same.
