Explosion Proof Motion Sensor
Instruction Manual
Thank you for your purchase of the EXP-MS-N4X-AT-HV 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.
This unit is designed to operate on 120V, 208V, 220V, 240V, or 277V AC electrical circuits. We also carry low voltage
12-24V AC or DC electrical systems. 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-MS-N4X-AT-HV 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.
