2.0 Programming

Program the address DIP switches as described for the control panel you are using.

Note: When installing with a D7212B1, D8112, or D9112B1; place switch number “0” in the ON position.

Recommended point type programming: D8112 = 7571

D9112B1/D7212B1 = Point type 2, point response 2, no ring until restored. D9412/D9112 = Point type 2, point response E, no ring until restored.

3.0 Mounting

Select a location likely to intercept an intruder moving across the coverage pattern (review Section 10.0 Coverage Patterns, page 8). The recommended mounting height is 7.5 ft. (2.3 m) when using the OA80 or OA120, or 10 ft. (3.1 m) when using the OA200. Each mounting surface should be solid and vibration free.

• Remove the cover by inserting a thin screwdriver into each of the slots at the top and bottom of the cover. Twist gently until the cover snaps free of the tabs on the base.

3.1 Bracket Mounting

Note: The use of the B334 Mounting Bracket (included) is strongly recommended when installing this detector.

Because variations exist in the surfaces of most mounting walls, most units are not mounted at perfect angles to the floor or walls. This may cause the pattern to point away from the “ideal” direction.

For example: A shift of only 1 degree will cause a pattern shift of 1.7 ft. (0.52 m) at 100 ft. (30.5 m). Under worst case conditions, this will cause the pattern to be aimed over the head of intruders at maximum range, or into walls of narrow corridors. What may seem to be poor range or catch performance, may be the result of improper alignment.

To insure proper catch performance, a bracket mounted detector permits the flexibility needed to properly adjust the direction of the coverage pattern.

ZX794Z Installation Instructions

If Mounting to the B334 Mounting Bracket:

1. Remove the cover of the bracket by inserting a thin screwdriver into the notch on the side of the bracket and twisting gently.

2. Insert the alarm and power wiring through the center hole from the rear of the B334 base. (Do not insert wiring if the bracket is to be surface mounted).

3. Mount the B334 to a standard single-gang switch or outlet box using the supplied Bevel Head screws. (If surface mounting the unit, use the wall screw/anchor assemblies or appropriate alternatives).

4. Remove the circuit board from its base. Press the two circuit board retainer tabs outward and lift the circuit board away from the base.

5. Remove the sticker covering the entrance from the back of the detector base.

6. Insert the threaded stud through the appropriate stud hole in the B334 bracket. Use the bottom hole for wall mounting, the front hole for ceiling mounting. Make sure the hex head is seated in place.

7. Complete the assembly by securing the detector base to the B334 bracket using the supplied curved washer and hex nut (see Bracket to Base Assembly drawing).

8. Hand tighten the hex nut.

9. Thread the bracket wiring through the stud and along the wiring channel in the detector’s base to the area of the circuit board’s terminal strip.

10. Return the circuit board to its base. Slide the back of the circuit board under the tabs at the back of the base, then snap the front into place.

11. Aim the detector in the desired general direction and tighten the hex nut using the supplied hex wrench.

12. Should the detector require realignment, loosen the hex nut, reposition the detector, and then retighten the nut.
