Ceiling Mount Multiplex Passive Infrared
Intrusion Detector with Self-Test
Specifications
Coverage:
360° by 60 ft. (18.3 m) diameter coverage when
mounted on 8 to 18 ft. (2.4 to 5.5 m) high ceilings.
Pattern consists of 64 zones grouped into 16 barriers,
with one additional zone looking straight down from
the unit (sabotage). Each barrier is 30 ft. (9.2 m) long
and 4.4 ft. (1.3 m) wide at 30 ft. (9.2 m). Choice of two
optical modules depending on ceiling height.
NOTE:
For U. L. Listed Requirements, the coverage is 360° by 54 ft.
(16.5 m) when mounted from 10 to 13 ft. (3.1 to 4.0 m) using
the AR8-13 Array and when mounted from 15 to 18 ft. (4.6 to
5.5 m) using the AR13-18 Array.
Input Power:
Supplied by polling loop.
Sensitivity:
Field selectable for Standard or Intermediate.
Temperature:
The storage and operating range is -20° to +120°F
(-29° to +50°C).
For U. L. Listed Requirements, the
range is +32° to +120°F (0° to +50°C).

Mounting
Select a location likely to intercept an intruder moving
across the
coverage pattern. See
Typical Placements to Achieve Coverage. The
recommended mounting height is 8 to 18 ft. (2.4 to 5.5 m).
NOTE:
The mounting surface should be solid and vibration free (e.g.,
drop tiles should be secured if the area above the tiles is used
as an air return for HVAC systems).
•
Do not mount near air handling system outlets, or in areas of extreme
drafts.
•
Remove the cover by turning it counterclockwise.
•
Remove the base from the enclosure by pressing the two enclosure
release tabs inward while lifting the enclosure away from the base.
HINT:
Slightly rock the enclosure side-to-side during removal to
overcome the friction caused by the base-to-enclosure terminal
pins.
•
Route wiring as necessary to the rear of the base and through the
center hole.
NOTE:
Be sure all wiring is unpowered (de-energized) before routing.
•
Firmly mount the base. Depending on local regulations, the base may
be directly surface mounted using anchors, mollies, or wing-nuts, or
may be mounted to standard four-inch octagonal or square electrical
boxes.
NOTE:
The R
X
360SN base will not completely cover a four-inch square
box. Where aesthetics are important, a four-inch octagonal box
is recommended.
HINT:
Mounting to removable ceiling tiles is not recommended unless
a sandwich is made of the base, ceiling tile, and a back plate
behind the tile. Covers used for four-inch octagonal and square
boxes make a suitable back plate (when used with bolts and
wing nuts, as an example).
Selecting the Optical Module (AR8-13 or AR13-18)
•
Replace the enclosure onto the base.
•
For ceilings between 8 and 13 ft. (2.4 and 4.0 m) from the floor, use the
optical module marked AR8-13. This marking can be found next to the
two optical module tabs.
•
For ceilings between 13 and 18 ft. (4.0 and 5.5 m) high, use the optical
module marked AR13-18.
•
To replace an optical module, push the optical module tabs towards the
center until the module snaps free of the circuit board. Holding the new
module by the tabs, snap the new module into place.
•
Avoid fingerprints on the mirrored surfaces. Should the mirrored sur-
faces become soiled or otherwise marked, they can be cleaned using a
soft, clean cloth and any commonly available, mild window cleaner.
