Description
Introduction
The ABB BM/A4.1-136 Busch-Watchdog PRO 280° (Product ID 2CKA006132A0429) is a 4-channel KNX movement detector finished in stainless steel, designed for automatic switching of ABB-i-bus KNX® actuators in both indoor and outdoor environments based on movement and brightness levels. Operating on KNX (TP) networks with KNX Data Secure protection, it incorporates a 280° motion detection range alongside integrated ground and rear-field detection for creep-under protection. This device is part of our KNX system devices range.
Engineered with an IP55 degree of protection, the detector provides flexible alignment capabilities including +/- 30° level balancing, +90°/-60° horizontal optical system orientation, and +30°/-30° vertical optical system orientation. It features integrated twilight/brightness and temperature channels with three switching thresholds each, status feedback through a 5-function programmable RGB LED, and remote operation via Bluetooth using the SmartConnect app for controlling up to 10 KNX functions.
Key Features
- 4-channel KNX movement detector with additional push-button switch-on object functionality.
