Installed the ALEM-280D on a set of double doors in a warehouse facility. The holding force is solid, keeping the doors securely locked without any issues. It performed well in varied temperature conditions during testing. Power consumption is low, which is a plus for our setup. No LED indicators, so we rely on external monitoring systems for status checks.

Installed the ALEM-280D on a set of double doors in a commercial facility. The holding force is solid and meets the security needs without any issues. Its robust build handles temperature fluctuations well, which is important for our unheated entryways. No LED indicators, but that was expected and doesn't affect performance for our application.
