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 ).

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
