u Point of protection intrusion transponder (POPIT)
u Tamper switch
u Two PIR sensitivity settings
The ZX835 TriTech® Microwave Passive Infrared (PIR)
Intrusion Detector only sends an alarm signal when
criteria activates the PIR and the microwave
technologies.
Functions
Tamper Switch
The ZX835 sends a tamper condition signal through
the POPEX data bus if the cover is removed.
Supervised Microwave and PIR Technologies
• PIR and microwave: The detector regularly performs
an internal self-test to check the microwave and PIR
subsystems. If the microwave or PIR subsystem fails,
the detector performs another test. If either
subsystem fails the second test, the light emitting
diodes (LEDs) flash red, indicating that you should
replace the detector. The ZX835 sends a trouble
signal through the POPEX data bus.
• Default: The PIR circuitry provides single technology
coverage if the microwave subsystem fails.
PIR Sensitivity Settings
Standard sensitivity: Minimizes false alarms and
tolerates temperature extremes.
u Four mounting options
u Immunity to certain animals, insects, and drafts
Intermediate sensitivity: Appropriate for applications
where an intruder moves through a small portion of
the protected area. This setting tolerates normal
environments and is appropriate to use when the
ZX835 is mounted higher than 2 m (6.5 ft). Do not use
this setting in areas with pets or animals.
Temperature Compensation
The PIR sensitivity increases and decreases according
to ambient temperature to detect human body heat
and avoid false alarms.
False Alarm Immunity
The ZX835 does not detect the following animals:
• One dog up to 45 kg (100 lb)
• Two 27 kg (60 lb) dogs
• Multiple small rodents, such as rats
• Up to ten cats
• Randomly flying birds
The sealed optical chamber provides immunity to
drafts or in-sects. The microwave processing identifies
and ignores repetitive false alarm sources and adjusts
to background noise, such as the vibration from
fluorescent lights.

Installation/configuration notes
Mounting Considerations
The mounting height range is 1.8 m to 2.4 m (6 ft to 8
ft). The recommended height is 2 m (6.5 ft). Surface
or corner mount the ZX835 to a standard single-gang
electrical box or use the B328, B335, or B800
Brackets.
The ZX835 tolerates changes in temperature and light
from heaters, air conditioners, drafts, sunlight,
lightning, and moving headlights. However, the ZX835
can respond to movement in its field-of-view or rapid
temperature changes. Point the ZX835 away from
windows, ceiling fans, and high-traffic roads.
