12/24v dc surface stainless steel mount external magnetic lock EM800 - (Monitored)

Holding force: 382kg
Magnet weight: 1.45kg
Armature weight: 0.700kg

The EM800 is for side or top mount fixing

The monitored option for magnetic locks simply means that the magnet status of it can be monitored to determine and confirm if the magnet is locked or unlocked. Inside the magnet is a set of voltage free Hall Effect contacts providing Normally Open and Normally Closed contacts (N/O & N/C)

With these contacts you can connect them to a sounder, buzzer, alarm system, light or anything else that would require a voltage set of free contacts to trigger the device when the magnet and the armature plate is separated

Some monitored magnetic locks will also have a dual red/green LED to indicate its open or closed status. The EM800 - (Monitored) does not have LED indication

Suitable for: Internal/external use. Surface ('L' bracket required) or side mount fitting on uPVC, timber or metal doors

FAQ's & tech tips
FAQ's & tech tips

The magnet is running very warm, almost hot
'Power to Lock' devices such as magnetic locks can run warm as they require constant power to them, however, the most common causes of this are the magnet is 12v dc operation, but the power supply is 24v dc
Electrical resistance in the circuitry will create heat but if the power supply is providing insufficient amperage then the magnet will feel hot
Also, if there is a current drop because of a long cable run with an inadequate wire gauge, the magnet will not get sufficient current and will run hot

The armature plate is vibrating
This is due to either a faulty or under rated power supply, or the magnet is 24v dc operation and the power supply is 12v dc

The magnet does not lock, the door can be pulled open quite easily
The most common cause is incorrect alignment of the armature plate to the magnetic lock, a faulty or under rated power supply, or the magnet is 24v dc operation and the power supply is 12v dc

Armature plate alignment

Tech Tips
This magnetic lock will operate via 12v dc or 24v dc, however, please ensure you check the wiring connections correctly for use with a 12v dc power supply or 24v power supply before you turn the power on
If you fail to check this, then you run the risk of either the magnetic lock running very hot or it not locking correctly
Eventually you will cause damage to the system you have installed
Periodically clean the surface of both the magnet and armature plate with light oil


'L' bracket installation

'Z' bracket installation

Please consider if you require any fixing brackets. Typically an 'L' bracket is required for outward opening doors. A 'Z' bracket is required for inward opening doors

L bracket weight: 0.500kg
L bracket size: 220l x 6d x (50 X 34h) mm
L bracket adjustment: 6 screw adjustment (3 each side) from -0mm forward to 23mm backward

Z bracket weight: 0.600kg
Z bracket size: 182w x 6d x 2 x (50 x 50h) mm
Z bracket adjustment: 6 screw adjustment (3 each side) allowing the armature plate to be aligned from -18mm forward to 40mm backward as well as angle adjustment up to 32 degrees
