Motion Detector AP 251/11

Description

The Motion Detector AP 251/11 is a surface-mounted

device with an integrated KNX interface for mounting

indoors or outdoors on a wall or ceiling. It works by

passive detection of body heat radiated in its capture

zone. Separate parameters can be set for the

beginning and end of detected movements, whether

these are to be reported over the bus, and whether a

further telegram is also to be sent. Because of its large

capture zone of 290°, the Motion Detector AP 251/11

is also suitable for mounting on a 90° outside corner. A

special mounting base is available for this purpose as

an accessory (p/n 5TC7900).

An infrared (IR) receiver is incorporated into the Motion

Detector AP 251/11. By using an infrared remote

control which is also available as an accessory (p/n

5TC7902), a user can independently set the detector's

mode (test mode, brightness-dependent or brightness-

independent mode, standard mode, pulsed mode), the

brightness threshold, and the delay time.

The factory setting of the detector’s mode is:

brightness-dependent motion detection with a

brightness threshold of 7 Lux and a delay time of 2

minutes.

The detector electronics are powered by the bus

voltage.

Application Programs

The Motion Detector AP 251/11 requires Application

Program 25 S1 Motion Detector 909101, which can be

configured and loaded with ETS (Engineering Tool

Software) Version ETS2 V1.3 and later.
