Does the M254 require a separate activation sensor, or can it handle both functions alone?

The M254 handles both door activation and safety protection in one unit. A separate activation sensor is not required, reducing the total number of components needed per door installation.

Product Q&A

Q:What type of sensor is the M254, and does it have anti-pinch safety protection?

The M254 is a dual-function infrared combination sensor. It includes both a motion relay for door activation and a presence relay for anti-pinch safety protection. If an obstruction is detected in the door path during closing, the presence relay triggers the door to reopen immediately, protecting pedestrians from injury.

Q:What is the difference between the motion zone and the presence zone?

The motion zone detects approaching pedestrians and sends an activation signal to open the door. The presence zone monitors the door gap area and keeps the door open or triggers a reopen if any person or object is detected in the closing path, providing anti-pinch safety protection independently of the activation function.

Q:Can the detection width and depth be adjusted after installation?

Yes. Both the motion zone and presence zone have independent width (narrow/wide) and depth (near/far) adjustment via onboard DIP switches, allowing on-site fine-tuning for different door widths and installation positions without removing the unit.

Q:How long does the presence relay stay active after the last detection?

The presence relay hold time is selectable via DIP switch: 15 seconds, 1 minute, 30 minutes, or continuous (always on), covering everything from standard pedestrian entrances to slow-moving access points such as hospital corridors or loading areas.

Q:Can the detection angle be adjusted after installation?

Yes. The sensor housing can be opened to adjust the detection angle, allowing the coverage zone to be fine-tuned for different installation heights and door widths on site.
