3. PYR-3011 H/G Features
• Advanced micro-controller electronics: 10-bit A-to-D and
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; by jumper
selection
• Power saving: Two transmission modes by jumper
• Extra wide free height installation: The detector may be
installed at any height between 2 and 4 Meters without
any PCB adjustment.
• Back and Front Cover tamper switches: Protection
against cover or wall removal for higher security.
• Easy & comfortable installation: Easy 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 H/G 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.
• AVOID: Placing near continuously moving objects.
• 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
brightness. In very dark place, the coverage would be less
than the normal coverage. Avoid placing near obstructions
such as large plants, curtains, behind open doors and places
where there are temperature shifts.
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, non-
vibrating 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.
Installation
height(M)
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 PIR
The PYR-3011 H/G 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
L-shaped 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).
5) Remove the back cover from the ceiling and drill. 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).
