Description & Specifications:
EM800SS Surface Mount External Magnetic Lock (Monitored)
Overview The EM800SS is a versatile 12/24V DC stainless steel magnetic lock designed for external use. It offers a strong holding force of 382kg (800lbs) and can be mounted on the side, face, or top of uPVC, timber, or metal doors.
As a monitored lock, the EM800SS allows you to confirm its status (locked or unlocked). It features a built-in Hall Effect sensor with voltage-free Normally Open (N/O) and Normally Closed (N/C) contacts. These contacts can be connected to external devices like sounders, buzzers, or alarm systems to signal when the magnet and armature plate are separated. Please note, this model does not have an LED status indicator.

Frequently Asked Questions (FAQs)
Q: The magnet feels very warm, almost hot. Is this normal? A: "Power-to-lock" devices like magnetic locks require constant power and can naturally run warm. However, excessive heat can be caused by:
- Incorrect Voltage: A 12V magnet connected to a 24V power supply.
- Insufficient Amperage: The power supply is not providing enough current.
- Voltage Drop: A long cable run with an inadequate wire gauge is causing a loss of current.
Q: The armature plate is vibrating. What's causing this? A: Vibration is typically caused by either a faulty/under-rated power supply or by powering a 24V magnet with a 12V supply.
Q: The magnet isn't locking properly. Why? A: The most common causes are:
- Misalignment: The armature plate is not correctly aligned with the magnetic lock.
- Power Issues: The power supply is faulty, under-rated, or providing the wrong voltage (e.g., 12V for a 24V lock).
Technical & Installation Tips
- Voltage Selection: Before powering on, double-check that the wiring connections match your 12V or 24V DC power supply. Incorrect wiring can cause overheating, locking failure, and eventual damage to the system.
- Maintenance: Periodically clean the surfaces of both the magnet and armature plate with a light oil to ensure optimal performance.
