3. PYR-3011 Features
• Advanced micro-controller electronics: 10 bit A to D &
advanced algorithms for superior movement speed spectrum
analysis
• Shielded quad-element Pyro: Inside a dust-proof chamber
designed to reduce thermal changes and insect protection
• Three levels of sensitivity: High, medium or low; jumper selection
• Power saving: Two transmission modes by jumper
• Extra wide free height installation: The detector may be installed
at heights between 2 and 4 Meters without PCB adjustment.
• Back and Front Cover tamper switches: Protection against cover
or wall removal for higher security.
• Easy comfortable installation: Without removal of PCB.
• Walk & Radio test: Check both in snappiness, with LED indication
and without open case.
• Energy detection system: By using fuzzy logic algorithms,
detection is improved and false alarms are reduced
• Environment temperature compensation: Maintains constant
detection capability
• Adaptive filter: Compensates for changes in a detected object’s
speed
• Continuous monitoring: Sends visual alerts in case of malfunction
(digital and analog) and temperature out of range
4. Installation
4.1 False Alarm Reduction Effort
To reduce false alarms caused by detector installation:
• AVOID: Wiring of the PYR-3011 in such a way that it is parallel
to and sitting close to 110V AC or 220V AC transmission
equipment or mains power line.
• AVOID: Placing near or under heat and air ducts, ovens, heat
sources, radiators, and air conditioners as this may cause a
false detection.
• AVOID: Placing near PL lamps, electrical ballasts, above
cookers, and ovens, and above steam sources.
• NEVER: Touch the Pyro-electric sensor on the PCB as this
causes permanent damage and loss of sensitivity.
Important Note: PIR works according to field of view and
cannot detect through walls. Avoid placing near
obstructions such as large plants, curtains, behind open
doors, and continuously moving objects.
4.2 Selecting the Physical Location
You need to select the best physical location to install the PIR.
To select a physical location:
1. Select a flat ceiling in a room or hallway that best matches
the criteria in False Alarm Reduction Effort.
2. Make sure that the PIR is mounted on a non-moving, nonvibrating surface of the room.
3. The field of view of the detector is about 50° vertical and the
coverage area depends on the installation height, refer to
the following table.

Coverage area
(diameters M)
2M 4.8
2.5M 7
3.3M 9
4M 13
Table 1: coverage area based on installation height
4. Mount the PIR in the selected location. (refer below to
Mounting the PIR section)
5. After the installation, perform a walk test from the mounting
location to ensure that the sensor pattern can detect within
the coverage area (see Testing the Detector)
4.3 Mounting the PYR-3011 PIR
The PYR-3011G PIR is designed for easy & quick mounting onto a
ceiling
To mount the PIR onto the ceiling:
1. There are 4 opened holes on
the back of the casing. Two Lshaped holes (A) and two
“water-drop” holes (B)
2. Open the back cover by
twisting the top cover counter
clock wise.
3. Place the back cover over the
installation location. Ensure that the screws are aligned with
holes B.
4. Mark the location for the mounting screws in holes B (wide
end), and drill holes in the ceiling
5. Place the plugs in the drilled holes and screw in the screws
leaving it out by about 4mm.
6. Pass the screws through the wide end of holes B. turn the
back cover counter clock wise until the screws rest at the
narrow end of holes B. Tighten the screws.
7. Insert the battery (check for correct polarity).
8. Replace the top cover over the back end as shown in the
drawing below (please note the arrow marks)
9. At this point, the detector starts a warm up period which
performs a self check for about 1-2 minutes. At the end, you
can start a walk test (refer to signaling and testing sections).

5. Jumper and Tamper Setting
PYR-3011 has two jumpers, JP1 and JP2 and one tact switch S3
(test mode) operated by the guide light switch on the external
casing.
5.1 Sensitive Level Jumper (JP2)
To prevent false alarms in harsh environments, three sensitivity
modes were designated:
• Low – for harsh environments, jumper on pins 2 and 3
• Medium – for normal usage, jumper off
• High – for high sensitivity when there is little chance of false
alarms, jumper on pins 1 and 2
