Frequently Asked Questions
What is the difference between the EM3500DM-BLK and the standard EM3500D?
The EM3500DM-BLK adds dual monitoring (LSS Hall Effect sensor and DSS reed switch) and comes in a black anodised finish. The standard EM3500D is non-monitored and available in a silver/natural anodised finish. Choose the DM-BLK when your access control panel requires real-time lock and door status feedback, or when a black finish is specified.
Is the EM3500DM-BLK fail-safe or fail-secure?
The EM3500DM-BLK operates in fail-safe mode — the door releases when power is removed. This is the required configuration for fire egress doors, ensuring occupants can always exit in an emergency.
Is this maglock fire rated?
Yes. The EM3500DM-BLK is fire rated to up to 4 hours in accordance with Australian Standards, making it suitable for installation on fire-rated double doors on compliant egress routes.
What does “zero residual magnetism” mean in practice?
It means the door releases instantly the moment power is cut, with no lingering magnetic force. This is critical for egress compliance and prevents the door from sticking after the lock is de-energised.
Does CCTV Guru ship the LOX EM3500DM-BLK Australia-wide?
Yes. We ship to all states and territories across Australia, including metro and regional areas.
