With a 4-hour fire rating, anti-tamper plate, zero residual magnetism, and dual 12V\/24VDC compatibility, it is the go-to monitored single maglock for Australian security installers and integrators.\u003c\/p\u003e\n\n\u003ch2\u003eDescription\u003c\/h2\u003e\n\u003cp\u003eThe “M” in EM3500M stands for monitored — and that distinction matters. Where the standard EM3500 simply locks and unlocks, the EM3500M continuously reports back to your access control panel: the Hall Effect LSS confirms the lock is properly engaged, while the reed switch DSS detects whether the door is physically closed. Together, they eliminate blind spots in your security system — triggering alerts if a door is forced, left ajar, or the lock fails to engage.\u003c\/p\u003e\n\u003cp\u003eThe slimline 238mm body mounts cleanly on single door frames without dominating the aesthetic, while the satin anodised aluminium and zinc-plated body resist corrosion in Australian commercial environments. The included anti-tamper fixing plate conceals the armature bolt fixings once installed, deterring physical attacks on the lock. Built-in MOV surge protection guards the internal circuitry, and zero residual magnetism ensures instant door release the moment power is cut — critical for safe egress in fire or emergency situations.
