Instruction Manual
Thank you for your purchase of the EXP-AKC-MS-N4X-AT-LV-12V Motion Sensor, the following instructions are
intended for this part number only.
Installation
This unit is easily wall mounted via integral mounting bracket, which can be adjusted -90° to +30° vertically after
installation. The explosion proof housing provides two 1/2" or 3/4" hub openings located on either side of the housing for
running electrical conductors in a feed through configuration. A bushing seal at each conductor opening prevents
damage to wiring insulation.
KNX Connections: This motion sensor operates on 12V DC and features two monitored inputs, as well as two
monostable relay outputs. The explosion proof interface is suitable for sending output signals from the motion sensor to
upstream systems. This unit contains bus terminals (black/red) for connection with KNX components. Screw terminals
are provided for connecting auxiliary voltage, inputs and outputs. This motion sensor is suitable for use in environments
where combustible dusts and particulates may be present. 1/2" or 3/4" NPT tapped conduit openings are provided on
either of the unit in feed through versions while dead end versions have a single conduit hub, providing easy and secure
connection to main power line supplies.
The EXP-AKC-MS-N4X-AT-LV-12V operates like a standard on/off light switch. The circuit is normally open when no
motion is present. Once motion is detected, the internal switch changes to a closed circuit, allowing voltage to pass
through the sensor and power the device(s) at the other end.
The sensor is an active motion detector; it emits high-frequency electro-magnetic waves (5.8GHz) and receives their
echo. The sensor detects the change in echo from even the slightest movement in its detection zone. A microprocessor
then triggers the "switch light ON" command. Detection is possible through doors, panes of glass or thin walls.
IMPORTANT:
persons or objects moving towards the sensor are detected best.
th
NOTE: the high frequency of the output of this sensor is <10Mw – that is just one 100 of the transmission
power of a mobile phone or the output of a microwave oven.
