Metway MA-DALIPIR Passive Infra Red Detector
The MA-DALIPIR presence detector is a sensor for automatic lighting control.
It detects movement using a PIR sensor, which updates the light controller using a DALI interface.
When an area is no longer occupied, the device times out after a configurable period.
This detector features our Progressive Sensitivity function to eliminate false triggering.
There is also an integral lux detector, enabling the sensor to control daylight linking.
Daylight linking can be configured either to keep lights off when there is sufficient ambient light, or used as part of a closed loop to maintain a pre-set luminance level in a dimmable system.
When using the lux detector, an extra DALI address is assigned to the unit.
Being DALI, the device ID is randomised during commissioning, and there is a visual alert showing when a device has not been addressed.
The walk-test mode, indicated by a built-in LED, helps when configuring the detector.
The MA-DALIPIR is connected via a screw terminal on the rear in a standard DALI two wire configuration, powered from the data line.
However, for applications where the current drain would be too high for the bus to be sustained, PIRs can be powered from the DALI64 using a 4-wire connection.
This neat, compact PIR is an ideal choice for mounting in trunking or on luminaires, and where aesthetics are important.
The MA-DALIPIR can also be specified with custom painted bezels to further help the sensor blend into the surface on which is it mounted.
