Motion Detectors
DELTA reflex motion detectors, IP55
16
Overview
The IP55 motion detector is a surface-mounted device, which
passively registers the thermal radiation of bodies moving within
its sensing range. It automatically switches the connected loads
on and off. The motion detection is indicated by a flashing red
LED integrated in the sensor.
No thermal radiation is detected through obstacles, such as
walls or glass panes, so there is no switching.
The brightness switching threshold and the delay time are infi-
nitely adjustable.
The device is also designed for inst
allation in existing staircase
lig
ht timer systems.
It cannot be guaranteed suitable for use in other applications.
Note: Further remote controls are available as optional extras for
the 290° IR version.
Design
The motion detector is suitable for wall or ceiling mounting.
Mounting of motion detector on the wall
Mounting of motion detector on the ceiling
If using the optionally available special base (5TC7 900 or
5TC7901), it can also be mounted on a 90° inside or outside
angle.
For optimum motion detection, the motion detector should be
mounted laterally to the direction of walking.
Positioning of the motion detector
The optimum mounting height is 2.50 m.
When mounting a light in the sensing range of the motion detec-
tor, there must be a clearance of at least 0.5 m.
Do not mount motion detectors directly above a light. Wherever
possible, it should be mounted underneath.
In order to avoid unintended switching operations, potential
sources of interference should be taken into consideration when
selecting the mounting location (e.g. flows of warm air, moving
bushes or branches). Areas that you do not want to monitor can
be blocked out by mounting the cover plates included in deliv-
ery.
