COVERAGE
SMALL MOTION 360 - PASSIVE INFRARED (PIR)
Ã Excellent detection of small motions from sitting or stationary occupants
(e.g. hand motions).
Ã 8 to 12 ft (2.44 to 4.57 m) mounting height recommended.
Ã ~500 ft
2
of coverage
Ã Line of site between occupant and sensor is required for detection.
Ã Sensor can not see through glass windows or doors.
Ã Detection range improves when walking across beams as compared to into beams.
Ã Spaces with small temperature differential between occupants and ambient may
encounter reduced sensitivity/range.

APPLICATIONS
SMALL SPACES
For control of small spaces like a private ofce, a single sensor linked to a wireless wall
switch controller (SWX-851) is recommended (see diagram on right). Linking additional
sensors is also an option if necessary. Switching from a second location (e.g. 3-way) is
achieved by linking a remote wireless wall switch to the wireless switch controller. Both
occupancy (auto-on) and vacancy (manual-on) operation are achievable in order to meet
energy code requirements.

LARGE SPACES
Multiple wireless sensors can be easily linked to a wireless power pack load controller
(SWX-950) to provide coverage for larger spaces (or larger loads) like an open ofce.
Additional functionality such as switching/dimming from multiple locations (e.g. 3-way)
or interfacing with wired control devices is achieved by linking to a wireless power pack
with appropriate functionality.

SENSOR PLACEMENT
Typically, a sensor should be located such that all entrances to the room/space are adequately covered.
Ideally, a sensor should be located so that its coverage beams are perpendicular to the door. This ensures
that an occupant is detected immediately upon entering. See Diagram 1. Note, however, it is important to
locate a sensor such that its coverage pattern can not extend through an open door, which could result in
detection of persons walking by, but not into, a room.
