• 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 re-alignment, loosen the hex nut, reposition the detector, and then re-tighten the nut.
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.
3.2 Surface or Corner Mounting
• Remove the circuit board from its base. Press the two circuit
board retainer tabs outward and lift the circuit board away from
the base.
• Select and break away the appropriate thin-wall wire entrance
covering 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. Firmly mount the base to the mounting surface.
Note: Be sure all wiring is unpowered (de-energized) before
routing.
If Mounting to the B334 Mounting Bracket:
• Remove the cover of the bracket by inserting a thin screwdriver
into the notch on the side of the bracket and twisting gently.
• 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).
• 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.
4.0 Wiring
CAUTION: ONLY APPLY POWER AFTER ALL CONNECTIONS
HAVE BEEN MADE AND INSPECTED.
Note: Do not coil excess wiring inside unit.
• Connect wiring as shown.
• 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.
• 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.
• 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).
• Hand tighten the hex nut.

5.0 Configuration Switch Settings
The ZX794Z has several features that are controlled using the
configuration switches.
condition is indicated at the detector by the Alarm/Test LED (see the
Supervision Display Chart, below).
• The LED indicates the cause of the supervision trouble once per
second using coded pulses.
The supervision features function as follows:
• PIR: The operation of the PIR is electronically checked approximately every 12 hours. If the PIR fails, the Alarm/Test LED will
flash 4 times.
• Motion Monitor Supervision: This feature verifies that the
detector has a clear view of the detection area. When selected
using switches S4 and S5, a supervision timer is activated. A
trouble condition will be indicated if the detector has not alarmed
at least once during the selected time period (this feature can be
disabled by placing both switches in the OFF position). The time
period selected should be long enough to allow adequate time for
holiday weekends.
5.1 LED Operation (S1)
• ON: Allows the Alarm/Test LED to operate when activated by
motion.
Refer to Section 5.0 (Configuration Switch Settings) for proper
switch settings.
• OFF: The LED will not operate on alarm activation, but will
indicate a supervision trouble condition or a stored alarm
event.
If the time period selected has elapsed from the last alarm, the
LED will flash 2 times and the Trouble Output will activate.
THE LED IS FOR WALK TEST ONLY. Disable the LED
by turning Switch 1 off for normal operation. Failure to
turn LED off will result in a Zonex bus malfunction.
It is recommended that the 30 day timer be selected. This verifies
that the unit is operational and avoids nuisance trouble conditions
caused by holidays, vacations, etc.
5.2 Sensitivity Mode (S2 and S3)
Sensitivity modes depend on the type of coverage desired and the
installation environment.
• Standard Sensitivity: Tolerates environment extremes on this
setting. Not recommended for OA120 and OA200 patterns. The
detector is shipped in Standard Sensitivity mode.
• Intermediate Sensitivity: The recommended setting for any
location where an intruder is expected to cover only a small
portion of the protected area. Tolerates normal environments on
this setting.
• High Sensitivity: The setting for fast response to intruder signals.
For use in quiet environments where thermal and illumination
transients are not anticipated.
If both switches are in the Off position, the unit will default to the
Intermediate setting.
Note: Although the sensitivity modes provide different degrees of
tolerance to environmentally caused alarms, the installer
should assure peak background noise voltage readings do
not exceed ±0.15 VDC. (See Section 8.0 Final Tests).
THE LED IS FOR WALK TEST ONLY. Disable the LED
by turning Switch 1 off for normal operation. Failure to
turn LED off will result in a Zonex bus malfunction.
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.
• Replace the front cover.
Note: All testing must be performed with the front cover in place.
5.3 Motion Monitor (S4 and S5)
Set switches S4 and S5 for the desired Motion Monitor time (see
Section 6.0 Supervision Features). The detector is shipped with
the Motion Monitor feature Off.
• Apply power to the unit.
• Wait at least two minutes, after applying power, to start walk tests.
Note: Walk testing should be done across the
coverage pattern as shown.
6.0 Supervision Features
The ZX794Z performs several supervision features that, combined
with the advanced motion detection capabilities of the detector,
provide an extremely high level of security. A supervision trouble

7.0 Setup and Walk Testing
• The edge of the coverage pattern is determined
when the Alarm/Test LED indicator (and
optional Sonalert™, if installed) first turns on.

Note:
The use of a Sonalert™ type device (sounder) will provide
an audible tone during the time the unit is in alarm. Of the
three available connector pins, the center pin is positive (+)
with respect to either outside pin (outside pins are common
(-)).
Sonalert™ is a trademark of Mallory.
Walk test the unit from all directions to determine the boundaries.
• After completion of the walk tests, remove the Sonalert™ (if
installed).
9.4 Mirror Module Information
• Excessive handling of the mirror surfaces may lead to performance degradation. Should these surfaces become soiled or
otherwise dirty, clean using a soft clean cloth and any commonly
available mild window cleaner.
9.5 Masking
• Refer to the mirror module and pattern drawings for masking
information.
• Before attempting any masking, be sure the chosen mirror surface
is the correct one. When attempting to remove any masking,
many adhesives will either destroy the mirror’s surface or leave
enough residue behind to reduce coverage performance.
8.0 Final Tests
Note: Meter readings are very important in
determining background disturbance
levels and catch margin sensitivity.
• Connect a 20,000 ohm/volt (or greater)
DC VOM to the Noise Voltage connector
pins as shown. Set meter scale for about
3 VDC. Route meter wiring through the
slot in the base. (Use of the TR6000 is recommended, but is not
essential for meter use.)
• Shaded areas of the mirror drawings do not affect the pattern and,
therefore, are not maskable.
10.0 Coverage Patterns
• The base reference level for reading background noise or target
voltages is approximately 2.0 VDC. Installations in quiet environments, therefore, will result in a steady meter reading between 1.9
and 2.1 VDC.
Voltage changes greater than 0.75 VDC from the reference level
are desirable for good catch performance. If changes are less
than ±0.75 VDC, the device may fail to respond at this distance if
the temperature difference between the intruder and the background is very small.
• Turn on all heating and cooling sources that would normally be in
operation during times of protection. Stand away from the unit and
outside the coverage pattern, then monitor the background noise
for at least three minutes.
ZX794Z readings should not deviate from the reference level
more than ±0.15 VDC. For readings outside these limits; eliminate
the cause, re-point the unit slightly, or mask off the affected
zones.
9.0 Other Information
9.1 LED Indicator Operation
• If viewing the operation of the Alarm/Test LED indicator is not
desired after setup and walk tests are completed, place switch S1
in the Off position.
9.2 Sealing the Wire Entrance
• The foam plug that is provided with the unit is for sealing the wire
entrance from drafts and insects.
9.3 Maintenance
• At least once a year, the range and coverage should be checked
according to Sections 7.0 and 8.0 (Walk Testing and Final Tests).
• To ensure continued daily operation, the end user should be
instructed to daily walk through the far end of the coverage
pattern. This assures an alarm output prior to arming the system.
