4. Installation
4.1 General
The PYR-2011A is designed for easy installation. Only a few steps
are required to install the PIR device.
To enable the Curtain Adapter for PIR detection on a focused
area, such as a corridor, or across a window or opening, follow
the instruction outlined in section 5.
When you are sure of the mounting location, follow the steps for
mounting the PIR, on a flat surface or in a corner, described
below.
4.2 Opening the PYR-2011A
The PYR-2011A housing can be opened by unscrewing a Philips-
head screw (1) and pushing the safety latch (2) to “unlock”.
4.3 Mounting the PYR-2011A PIR
Select an area for mounting the PYR-2011A, and ensure the
location is flat, either a wall or a 90-degree corner, for perfect
mounting of the unit. Ensure the PIR has a “view” of the area
under surveillance and is free from obstructions.
The PYR-2011A has a detection range of 14.7m (48 ft.) when
placed at a height of between 1.8m and 2.3m.
When using the Corner Mount, first of all place the plastic
bracket in the Corner, at the exact chosen location. Pay
attention, the Bracket has a Direction, the narrow edge faces
downwards. Next, attach it firmly to the wall; all 4 screws must
be inserted. Now inset the Body of the PYR into place over the
plastic bracket, using the corner mounting holes. If the
installation is done properly the plastic pipe/pole will press the
“back tamper” correctly.
4.4 Wall Mounting
The PIR housing has “dimple” points for insertion of screws, for
either wall-mounting or corner mounting (refer to detailed
pictures below). Remove the PC board prior to mounting.
NOTE: Be careful not to touch the pyro-electric unit on the board.
Touching the unit will gravely affect its ability of the unit to work
properly.
4.5 Closing the detector
After mounting the detector, insert a battery (refer to 6). Place
the PCB back in place and close the detector in reverse order.
Wait till detector finishes self-test (refer to Signaling Table), and
perform a self test.
NOTE: When using the swivel mount refer to the BR-11 installation
manual.
5. Adding the Curtain Adapter
Use the Curtain Adapter for detecting movement in narrow places
(corridors) or across surfaces (window).
You will need to remove the lens only to add or remove the Curtain
Adapter.
1) Turn the top part of the PYR-2011A over and locate the
lens' “holder pin” (A).
2) Gently remove the pin using a screwdriver under the
“holder pin” by lifting the pin up out of its place.
3) Gently push the two latches on the side of the lens inwards,
turn the housing over and pop off the lens.
4) Place the Curtain Adapter onto the lens area on the front
of the housing. Be sure to place the guide pins into the two
holes at the lower part of the lens area.
5) Replace the Lens
6) Turn the whole assembly over and replace the “holding
pin” that holds the Spherical lens in place. Be sure to place
the “holding pin” between the lens tab and the housing,
with the flat side toward the lens tab.
