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 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.
