Frequently Asked Questions
What is the difference between LSS and DSS monitoring?
LSS (Lock Status Sensor) monitors whether the electromagnetic bond is engaged — confirming the lock is physically holding the door. DSS (Door Status Sensor) uses a built-in reed switch to detect whether the door is physically open or closed, independent of the lock state. Together, they give your access control panel complete real-time visibility of both the lock and the door.
Is the EM3500FM suitable for sliding doors?
Yes. The flush-mount (recessed) design makes the EM3500FM particularly well suited to sliding door applications, where the lock body is installed within the door frame header and remains completely hidden when the door is closed.
Is the LOX EM3500FM fire rated?
Yes. The EM3500FM is fire rated to up to 4 hours in accordance with Australian Standards, and carries CE and RCM (C-Tick) approvals, making it suitable for fire-rated doors on compliant egress paths.
What warranty does the EM3500FM carry?
The EM3500FM is covered by the LOX Locking lifetime replacement warranty, reflecting the brand’s confidence in the long-term reliability of this product.
Does CCTV Guru ship the LOX EM3500FM Australia-wide?
