Lockwood ES9000 PRELOAD E/STRIKE 10-30VDC Monitored

The Lockwood Padde Series ES9000 has been designed to suit the harshest commercial environments, and has the unique feature of the ability to operate with up to 25kg of pre-load pressure on the keeper. Pre-load is a common condition that is caused by pulling on a door before it unlocks, the weight of warped or drooping doors, seals on fire doors or by differential air pressure created when heating and cooling systems are in use.

Key Features:

• Operates under pre load up to 25kg
• Easy field selectable fail safe/fail secure
• Multi voltage 10-30Vdc
• 1300kg holding force
• 2.5 million cycles endurance rating
• Latch keeper is significantly quieter in operation
• Weather resistant
• Mounting tabs as standard
• Non handed
• TRICARE® 5 Year Warranty
• Weather Resistant (IP54)
• Built in Protection Diode

Applications

• High traffic areas
• Doors subjected to side load (pre load)
• Fire rated door sets
• Open in/open out doors
• Suitable for use with all access control systems

The Lockwood ES9000 Preload Electric Strike (10–30VDC, Monitored) is a heavy-duty commercial electric strike designed for access control systems. All variants share the same core features:

• Pre-load operation – works even with up to ~25 kg of pressure on the latch

• Multi-voltage input: 10–30 VDC

• Field-selectable Fail Safe or Fail Secure

• Full monitoring (solenoid status + door/latch status)

• High holding strength (commercial grade)

• Designed for high-traffic and commercial doors

The difference between the part numbers is not electrical or functional — it is purely about the physical lip configuration to suit different door frame preps.

🆚 Variant Differences Explained

🔹 AA-ES9000

Standard model with no extended lip.
Used when the door frame is cut to standard electric strike dimensions.

Best for:

• New installs with correct frame prep

• Aluminium and steel frames already designed for ES strikes

🔹 AA-ES9000-020 – 8 mm Extended Lip

Includes an 8 mm protruding lip on the strike face.

Best for:

• Frames where the strike pocket is slightly recessed

• Situations where there is a larger gap between door and frame

• Retrofit installs where the original cut-out is deeper than normal

🔹 AA-ES9000-060 – Extended Lip with Fixing Holes

Has an extended lip with pre-drilled fixing holes.

Best for:

• Installations requiring extra mechanical strength

• Timber frames or custom metal frames

• Situations where you need to screw through the lip for a firmer mount

📌 Quick Comparison

All three versions perform identically electrically and mechanically — the only difference is how they physically sit in the door frame. The correct choice depends entirely on the door frame depth and how the strike needs to be mounted.
