Description
HDL M/SIS05.1 is a recessed KNX presence sensor integrating PIR occupancy, temperature and brightness sensing. It supports automatic and semi-automatic room lighting controls and configurable KNX logic.
Detection and control
- Passive infrared movement/presence detection
- Temperature and room illuminance measurement
- Four independent logical blocks plus one combined block, each with up to ten object outputs
- AND/OR logic, single or master/slave modes and configurable status feedback
- Automatic and semi-automatic lighting control and constant-brightness operation with suitable actuators
Electrical and mounting
- Network supply: 21–30 V DC KNX bus
- Manufacturer front dimension: Ø85 mm; manufacturer described movement coverage 12 m diameter at 3 m mounting height. Confirm actual cut-out and mounting type against the supplied housing
- Ceiling-mount operation; actual detection coverage depends on ceiling height and movement type
Planning
Use a compatible KNX electrical installation and commission parameters in ETS. Avoid mounting near heat sources, airflow and strong interference. Detection capability is for automation, not a certified security alarm.
