Key Performance and Usage Notes
Based on the above parameters, here are some key points:
High Locking Force and Safety Design: A locking force of up to 2000N and a "power-off unlocking" principle mean the lock will automatically open in the event of a power outage. This is both a safety feature (allowing the door to open in an emergency) and a factor to consider in environments with unstable power.
Harsh Environmental Adaptability: Its IP54 protection rating and operating temperature range of -20°C to 55°C indicate its ability to withstand industrial or outdoor environments with dust, splashes, and wide temperature differences.
Clear Installation Direction: Before purchasing, you must select the corresponding model according to the actual opening direction of the door (left-hand or right-hand). This is consistent with the two installation directions mentioned on the website.
Regarding the "Indicator Light" Function: The information found does not clearly specify the specific function of the indicator lights (such as power, lock status, fault indication). During actual installation and wiring, you need to refer to the actual product or a more detailed manual to confirm.
