MSC SERIES
Uses the Latest Passive Infrared and Ultrasonic
Technologies
MSCD/MSCP
MSCU
MSC Series Occupancy Sensors employ passive infrared (PIR)
and/or ultrasonic technologies to accurately detect occupancy and
automatically switch room lighting.
The low-profile sensor is ceiling-mounted to maximize motion
sensitivity in large areas with obstructions. With a 360 degree field of
view, and up to 2000 square feet of coverage area, the ceiling-mounted
occupancy sensor is ideal for conference rooms, classrooms, multi-stall
bathrooms, and large office areas.
The MSC series also incorporates an integral photosensor to prevent
lights from switching on when sufficient ambient light is present, as
commonly found in windowed areas.
Installation and configuration are simple. The sensor readily mounts to
drop ceilings, and it features front adjustments for setting sensitivity
and time delay. The sensor also features an auxiliary relay for use with
building automation and HVAC systems.

The AA47 Line-Switching Power Pack provides local switching capability
to control loads at a signal from MSC Series occupancy sensors,
independent of any connection to building control systems. The AA47
routes 120/277 Vac, 60 Hz line power directly to a Form A relay contact
(SPST) to control a load and generates full-wave, 24 Vdc to power up
to four MSC sensors (dependent on model). The AA47 can be mounted
either inside or outside an electrical box, and sensor power can be
routed via plenum-rated cable to the sensor(s).

The AA48 Auxiliary Relay is a low-voltage relay device for expanding the
switching capacity of an AA47. It can be used to control loads connected
ot
to additional circuits in response to a signal from a connected sensor.
It is essentially a relay with a SPST output controlled directly by the
occupancy sensor. The auxiliary relay can be mounted inside or outside
of an electrical junction box.
