Introduction

Monitoring

The patented MEM 2400LED Mechanical Electro Magnet locking device is designed for securing all types of 
inward opening side hung hinged doors. The MEM lock has a holding force of up to 1000KG and is equipped 
with a LED light feature for Secure (green) / Insecure (red) local monitoring indication on the device. The 
MEM2400LED has been Fire Tested for up to 4 hours to both AS & BS Standards. The MEM2400LED locking 
device is capable of releasing under door back pressure (pre-load) of up to 70KG. The unit comes with an L&Z 
Bracket as standard.        

The MEM2400LED lock is provided with a number of unique monitoring features for either local or remote 
indication:
i. Door Status Signal (DSS) 1 set of normally open contacts (N/O -- blue).
ii. Lock Status Signal (LSS) 1 set of normally open contacts (N/O -- yellow).
iii. Early Warning (EW) x 2.  2 sets of single throw double pole switches. 
                                                                                        EW1: (N/O -- purple); (COM -- orange);  (N/C -- pink). 
                                                                                        EW2: (N/O -- gray); (COM -- brown); (N/C -- white ).

MEM2400LED Mechanical Electro Magnetic Lock

for Inward Opening Doors

Functions

The MEM2400LED Mechanical Electro Magnetic Lock operates on either 12 or 24 VDC. It is set ex-factory on 
24VDC and can be changed over to 12V DC by voltage jumper selection. When power is applied to the lock and 
the door is in the closed position the Armature Plate is magnetically attracted to the MEM device and both the 
DSS & LSS switches change status to NC.
When pressure is applied to the door in an attempt to open it unauthorised, the MEM Lock provides the patented 
local or remote “Early Warning” (EW) security alarm indication.

The operating switch or controlling contacts must be installed directly from the power source across the MEM 
Lock. The DC output of the power supply must NOT be connected to earth but floating to prevent shock and 
possible damage to the unit.

Wiring and Power Input 

Power Supply

Ensure that wiring is connected correctly before supplying power to the MEM Lock to prevent 
damage to the unit.
