The mounting surface should be solid and vibration free.
IMPORTANT
• Select a location that is most likely to intercept an intruder moving across the coverage pattern. The recommended mounting height is 10 ft. (3.1 m) for 200 ft. (61 m) mirror. The recommended mounting height is 7.5 ft. (2.3 m) for 80 ft. (24 m) and 120 ft.
(36.6 m) mirrors.
• Remove the cover by inserting a thin screwdriver into each of the four slots on the cover. Twist gently until the cover snaps free of the tabs on the base.
• Remove the circuit board/mirror unit from the enclosure. Push the board/mirror unit toward the top of the enclosure until it clears its four retainer tabs, then lift it out.
3.1
Bracket Mounting
IMPORTANT
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. To ensure proper catch performance, a bracket mounted detector permits the flexibility needed to adjust the direction of the coverage pattern.
Note: Misalignment of the detector when using an optional mounting bracket may reduce range and increase dead zones.
• Remove the cover of the bracket by inserting a thin screwdriver into the notch on the side of the bracket and twisting gently.

B334 Bracket
• 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).
• 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).
• Remove the circuit board from its base. Press the two circuit board retainer tabs outward and lift the circuit board away from the base.
• Remove the sticker covering the entrance from the back of the detector base.

Locking Washer
Notch
Note: The use of the lock washer will reduce the chances of detector misalignment due to accidental bumping in the field. Placing the lock washer between the bracket and the detector enables it to bite into both the bracket and the detector when the assembly is tightened.
• Hand tighten the hex nut.
• 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.
• 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.
• Aim the detector in the desired general direction and tighten the hex nut using the supplied hex wrench.
• Should the detector require realignment, loosen the hex nut, reposition the detector, and then retighten the nut.
3.2
Surface or Corner Mounting
• Select and break away the appropriate thin-wall rear or surface wire entrance in the detector base.
• Using the base as a template, mark the location of the mounting holes on the mounting surface. Pre-start the mounting screws.
• Route the wiring to the rear of the base and through the wire entrance. Securely attach the base to the mounting surface.
• 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.

Wiring
Only apply power after all connections have been made and inspected.

OPEN • Connect wiring as shown.
Note: Do not coil excess wiring inside unit.
• Seal the wire entrance using the foam plug provided.
Terminal Descriptions
• 1 (B+) and 2 (B-): Connect to the Multiplex Bus of the control panel. Use no smaller than #22 AWG (0.8 mm) wire between the detector and the control panel.
• 3 (+) and 4 (-): Connect to the AUX Power of the control panel.
This connection is only required if LED operation (other than during the walk test) is required. Use no smaller than #22 AWG
(0.8 mm) wire between the detector and the control panel.

Configuration Switch Settings
The MX794i has several features that are controlled using the configuration switches set according to the following diagram:
Curved Washer

• Insert the threaded stud through the appropriate stud hole in the
B334 bracket. Use the bottom hole for wall mounting or the front hole for ceiling mounting. Make sure the hex head is seated in place.
• Complete the assembly by securing the detector base to the
B334 bracket using the supplied lock washer, curved washer and hex nut (see drawing).

LED Operation (S1)
• ON: Allows the Alarm/Test LED to operate when activated by motion.
• OFF: The LED will not operate on alarm activation.
Page 2 © 2011 Bosch Security Systems, Inc.
MX794i Installation Guide
If the detector is powered by the MUX Bus only, the LED is for Walk Test purposes only. Disable the LED when
Walk Testing is complete. To disable the LED, place the
Configuration Switch (S1) in the OFF position.
If the detector has AUX power supplied, the LED operation may be left on during normal use.
5.2
Sensitivity Mode (S2, S3, and S4)
Note: Sensitivity depends on the desired coverage and the installation environment.
• Standard: Tolerates environment extremes on this setting. Not recommended for OA200 coverages.
• Intermediate: The recommended setting for OA200 coverages or for locations where an intruder is expected to cover only a small portion of the protected area. Tolerates normal environments on this setting.
• High: The setting for fast response to intruder signals. For use in quiet environments where thermal and illumination transients are not anticipated.
6.0
Address Switch Settings
• Set the address switch settings (see page 4) before connecting the MX794i to the multiplex bus.
IMPORTANT
No two devices may be set to the same address. Having two or more units set to the same address may prevent fault detection or cause multiplex bus failure.

Setup and Walk Testing
If a different optical module is to be used:
• Slide the current module free from its housing. Install the new optical module onto the housing. Make sure it snaps into place.
Note: Excessive handling of the front mirrored surfaces may lead to performance degradation.
Before walk testing, the system should be fully wired, powered, and programmed.
IMPORTANT
• Configure LED Configuration Switch (S1) to LED ON.
• Replace the front cover.
Note: All testing must be performed with the front cover in place.
• Wait at least 2 minutes (with no motion in the coverage area) for the detector to setup.
• Walk test across the coverage pattern.
• The edge of the coverage is determined by activation of the LED.
• Walk test the unit from both directions to determine the boundaries.
On 2-wire systems, configure the LED to OFF when finished with walk tests.
IMPORTANT
8.0
Maintenance
• The range and coverage should be checked according to the
Walk Test and Final Tests (Sections 7.0 and 8.0) on a regular basis.
• Consult the Control Panel User's Guide for the procedure on performing a zone test. Performing a zone test on a regular basis assures an alarm output prior to arming the system.
• Should the mirror surfaces become soiled or dirty, clean using a soft clean cloth and any commonly available mild window cleaner.
9.0
Coverage Patterns
• Refer to the mirror module and pattern drawings for masking information.
• Before masking, be sure the chosen mirror surface is the correct one. When removing masking, remember, many adhesives will either destroy the mirror’s surface or leave residue behind to reduce coverage performance.
• Shaded areas of the mirror drawings do not affect the pattern and, therefore, are not maskable.

IMPORTANT
Zone (Point) Addresses 001 through 008 are reserved for "on board" points on the DS7400(Xi) Series Control
Panels. Do not set any multiplex devices for Addresses
001-008 when using a DS7400(Xi) Series Control Panel.
