LOX EM3500 Non-Monitored Single Electromagnetic Lock – 280kg Holding Force, Dual Voltage, Fire Rated
Overview
The LOX EM3500 is a high-performance slimline single-door electromagnetic lock built for reliable commercial and residential access control across Australia. Delivering a proven 280kg (600 lb) holding force from a compact 238mm body, the EM3500 is the cost-effective, non-monitored choice for standard secure doors where external monitoring sensors are already in place or not required. With a 4-hour fire rating, zero residual magnetism, and dual 12V/24VDC compatibility, it is one of the most widely installed single maglocks in Australian commercial buildings.
Description
The EM3500 is the entry point to the LOX electromagnetic lock range — and it sets a high bar. Its slimline satin anodised aluminium body mounts cleanly on standard single door frames without dominating the aesthetic, making it equally at home in a modern office fitout or a utilitarian warehouse entry. The non-monitored design keeps the installation straightforward: power on to lock, power off to release — no additional sensor wiring required.
Zero residual magnetism means the door releases the instant power is cut, with no sticking or delay — critical for safe egress in fire or emergency situations. Built-in MOV surge protection guards the internal circuitry against voltage spikes, and dual 12VDC/24VDC compatibility ensures it integrates with virtually any access control power supply or panel in use across Australia. Tested to over 1,000,000 cycles for long-term, maintenance-free reliability.
For applications requiring real-time lock status or door position monitoring, consider the LOX EM3500M (monitored version) which adds Hall Effect LSS and reed switch DSS sensors as standard.

Frequently Asked Questions
What is the difference between the EM3500 and the EM3500M?
The EM3500 is the non-monitored version — it locks and unlocks but provides no status feedback to your access control panel. The EM3500M adds dual monitoring via Hall Effect LSS (lock status) and reed switch DSS (door status), plus an anti-tamper fixing plate as standard. If your access control system requires real-time feedback, alarm integration, or audit trail compliance, the EM3500M is the correct choice.
Is the EM3500 fail-safe or fail-secure?
The EM3500 is a fail-safe electromagnetic lock — it releases (unlocks) when power is removed. This is the standard and required configuration for most commercial and fire-rated single door applications in Australia.
What brackets do I need for the EM3500?
The correct bracket depends on your door swing direction. For inward-opening doors, use the LOX AMZB4-LP L & Z bracket. For outward-opening doors or narrow frames, the LOX AMLB4 adjustable L-bracket is the correct choice. Using the wrong bracket will result in misalignment and reduced holding force.
Is the EM3500 suitable for fire-rated doors?
Yes. The EM3500 is certified to AS/NZS Standards for use on fire-rated door assemblies for up to 4 hours, meeting Australian building code requirements for fire-rated access control hardware.
Does the EM3500 include an armature plate?
Yes. The EM3500 is supplied with a matching armature plate (185mm × 38mm × 12mm). Mounting brackets are sold separately depending on your door configuration.
What voltage does the EM3500 operate on?
The EM3500 supports both 12VDC and 24VDC operation, making it compatible with the vast majority of access control power supplies used in Australian installations.
Do you ship Australia-wide?
Yes. We ship to all states and territories including NSW, VIC, QLD, WA, SA, TAS, ACT, and NT. Contact us for bulk order pricing and project quotes.
