The LOX ES90M High Security Monitored Electric Preload Strike is a commercial-grade electric door strike featuring 25kg preload capacity, 1300kg holding strength, 10–30VDC operation and triple-status monitoring. Designed for Australian-footprint door installations, this IP54-rated electric strike delivers reliable access control performance with field-selectable fail-safe and fail-secure operation.
Engineered for demanding commercial security applications, the LOX ES90M operates under up to 25kg of preload pressure on the keeper. This capability helps maintain reliable door release where conventional electric strikes may struggle due to air pressure differentials, door misalignment, warped doors or heavy weather seals.
Manufactured from high-grade stainless steel, the ES90M combines durable construction with flexible installation options. Its field-selectable Power to Open (PTO) / Power to Lock (PTL) configuration allows installers to switch between fail-secure and fail-safe operation using a small screwdriver without dismantling the strike.
A standard 10mm strike lip helps minimise clothing snags and potential injury, while pre-drilled mounting points accommodate optional extension lips for different door-frame requirements.
The ES90M also incorporates three independent monitoring functions: Lock Status Sensor (LSS), Door Latch Sensor (DSS) and Anti-Tamper Sensor (ATS). These provide valuable feedback about the locking mechanism, latch engagement and strike installation integrity to compatible access control systems.
With a holding strength of up to 1300kg, IP54 weather resistance, Australian security and durability ratings, and a 5-year warranty, the LOX ES90M is a dependable solution for high-security commercial door access control.

Advanced Monitoring Functions
The ES90M features three monitoring outputs designed to provide additional security information to compatible access control and alarm systems.
1. Lock Status Sensor (LSS)
Monitors the internal locking mechanism, indicating whether the strike is in its locked or unlocked condition. This supports remote lock status verification and security system monitoring.
2. Door Latch Sensor (DSS)
Detects whether the door latch is engaged within the electric strike keeper. This enables monitoring of latch engagement and provides useful feedback about door security.
3. Anti-Tamper Sensor (ATS)
Detects when the electric strike is removed from its installed position, supporting tamper detection and alert functions where connected to a compatible monitoring system.
Practical Applications and Use Scenarios
Commercial Offices and Corporate Buildings
Ideal for controlled entry doors, office access points and restricted work areas requiring secure electronic locking with lock and latch monitoring.
High-Traffic Building Entrances
The preload capability and high holding strength make the ES90M suitable for busy commercial doorways subject to repeated operation and changing pressure conditions.
Healthcare and Educational Facilities
Suitable for access-controlled internal doors and staff-only areas requiring reliable locking and monitoring, subject to applicable safety and building regulations.
Doors with Weather Seals or Air Pressure Differentials
The 25kg preload capability helps improve door release reliability where heavy seals, ventilation pressure or minor door alignment issues place additional force on the strike keeper.
Security-Sensitive Facilities
The combination of high holding strength, lock monitoring and anti-tamper detection supports installations where visibility of door locking status is important.
Building Access Control Upgrades
The Australian-footprint format, multi-voltage operation and field-selectable locking modes provide flexibility when upgrading compatible commercial door access systems.
