INTRODUCTION
The SX EX ELECTROMAGNETIC LOCK (also known as the SX Ex Maglock) is a
member of the unique SecurEx SX product family which has been specifically
designed for use in harsh hazardous (Ex) environments.
This unique certified device works with both our door controller and access products
or with third party ACU systems to provide a highly effective security solution for
access control in Ex classified hazardous areas Zones 1, 2, 21 & 22.
Developed and manufactured for SecurEx under license by our partner company, Wath Group Ltd this
unique Sx Ex Electromagnetic Door Lock has been specifically designed to be a true ‘Ex Certified’
Security Locking product. Elegantly designed with both ‘form and function’ in mind, the lock is
manufactured from a single solid mono-block of 316 Stainless Steel and is supplied as standard
factory fitted with a 5-metre multi-core user cable.
Engineered to withstand loads of up to 550 kgf / 1200 lbs, the unit may be fitted to a wide variety of
door configurations including left or right-handed and in or outward opening doors by using the
appropriate approved matching mounting systems (sold separately). Cabling can exit to either the
right or the left-hand side of the lock as required to suit the installation as the unit can be fitted in any
orientation. The fully sealed IP67 unit is suitable for use in on-shore and off-shore environments and
the lock is available in a choice of 12 or 24V DC versions.
In most standard configurations the unit is usually supplied fitted with door status monitoring and is
provided with a special door armature (Keeper unit), which includes a door status magnet. For higher
security applications, the product has been designed with special versions available providing graded
door status contacts with anti tamper and product fault monitoring.
The wide variety of configurations available for this locking system make it particularly useful when
used as part of an integrated access control solution where it can provide both enhanced safety and
security for personnel.

MECHANICAL INSTALLATION
PRODUCT ONLY SUITABLE FOR
END USER INSTALLATION ONLY
BY APPROPRIATELY QUALIFIED
PERSONNEL
Installation Considerations
The SX-LS-P7XXXXA series Electromagnetic
locks can be installed and used just like a
conventional electromagnetic lock by being
fitted onto the frame and acting on the armature
plate (keeper unit) which is usually mounted to
the top of the door.
Mechanical Installation
Basic installation requires 4 x M6 Mounting
bolts for the lock.
The Lock is provided as standard fully
assembled with a 5 m user cable factory fitted.
DOOR PREPARATION
Door preparation details are shown on the GA
drawings for the Electromagnetic Lock and
Armature (Keeper) which can be found on the
center pages of this manual.
Care MUST be taken to carefully align the lock
and armature units. This is essential both to
correctly align the door sensor system and to
ensure full engagement of the armature for
optimum performance of the lock.
Depending on the door type you are fitting the
lock to, both the door and frame will need to be
appropriately prepared, drilled and tapped. This
may require appropriate rivet nut inserts to be
fitted or hank bushes to be installed.
Furthermore, depending on the door
configuration, the use of approved matching
mounting systems may be required – See
Mounting Options.

MOUNTING OPTIONS
MOUNTING OPTIONS
The SX EX ELECTROMAGNETRIC LOCK has been designed for use on a wide range of door types and
configurations including use on both inward and outward opening doors.
Each lock is provided as standard as a two-part set comprising the Electromagnetic Lock and The Armature
Plate (Keeper).
6
OUTWARD OPENING DOORS
A common mounting arrangement for outward opening doors is for the magnetic lock to be fitted neatly
beneath the door frame with the Armature Plate being fitted directly to the door which then closes directly
onto the lock. This requires our optional custom L bracket.
INWARD OPENING DOORS
A typical mounting arrangement for inward opening doors is for the magnetic lock to be fitted directly to the
outside face of door frame with the Armature Plate being stepped off of and up from the door to close
directly onto the lock. This arrangement requires our optional custom Z bracket.
Note: Due to common mounting points the Z bracket can also be used to mount the lock in an alternate
mounting arrangement if required.
MOUNTING KITS
The following kits are available at extra cost:
L Bracket Kit - P/N SX-LS-M70101A
Comprising an L bracket which is designed to
allow the lock to be neatly mounted under the
door frame whist the receiver plate is directly
mounted to the door. Due to common mounting
points this can also be used to mount the
armature (keeper) plate in an alternate
mounting arrangement if required.
Z Bracket Kit - P/N SX-LS-M70201A
Comprising a 2-part adjustable Z bracket, this
kit allows either the armature (keeper) plate or
the lock itself to be set off of the door or frame.
The bracket provides an adjustable offset
clearance of up to 75mm.
S Bracket Kit P/N SX-LS-M7040XA
The S bracket option allows us to create special
custom brackets designed to meet a specific
clients unique requirements.

SPECIAL NOTE 3:
Only competent personnel should carry out the
electrical connection of this product.
Driver circuits to the lock and the magnetic switch
should be appropriately fused / protected in line as
specified by the ‘X’ conditions to prevent exceeding
the design limits set out in the Technical
Specifications section.
‘SLO-BLO’ is the minimum requirement for fusing
as shown in the tables (see left). We recommend
fused terminals are fitted for this purpose, located
close to the ACS.
To prevent the risk of hazardous voltages
accidentally being transmitted into the hazardous
area we recommend that power to this device is
supplied from a suitable power source, e.g.,
isolating transformer / PELV source.
The user cable is mechanically braided for
protection. However, the electrical installer should
take such additional measures to protect the cable
when installed on-site as may be necessary to
comply with local regulations and good installation
practice. This may require routing the user cable
through an appropriate protective conduit.
For additional protection a safety earth point is
provided. This can be found beneath the gland on
the cable entry side of the Electromagnetic Lock.

LOCKING MECHANISM
When correctly installed mechanically and electrically as described above, the SX EX
ELECTROMAGNETIC LOCK will provide both a reliable locking solution and door status information
for access control purposes.
Locking is achieved when the armature (keeper) is in full contact with the Electromagnetic lock and
either 12V DC or 24V DC is applied (depending on product version).
When electrically locking the door, ideally the lock should ONLY be energized when ‘door closed
status’ has been detected AND after allowing ‘settling time’ to ensure the door to be completely come
to rest in its normal closed position.
SPECIAL NOTE 4:
This is a ‘permanently energized to lock’ product. The case is specially designed to dissipate
heat and acts as a natural heat sink. The external temperature of the unit will therefore rise
under normal use and may become hot.
DOOR STATUS MONITORING
To monitor ‘door status’ the magnetic switch contacts should be appropriately whetted by the
monitoring / ACS system with low current 12/24V DC. The contacts operation may be used by the
monitoring / access control system to positively confirm the state of the secured door.
Contact operation will correspond to the door being opened or closed in line with the truth table for the
specific type variant being supplied. See the Connectivity Wiring & Fusing Table by Model Number on
pages 8 & 9 of this booklet.
The minimum fusing requirements for the door contact should be adhered to in order to comply with
the ‘X’ Conditions of this product.

When used in harsh outdoor conditions, we recommend regular routine maintenance as follows:
• Regularly check the Electromagnetic Lock for correct operation.
• Regularly test the switch contact functionality with the monitoring system for correct contact
operation.
• Regularly clean and remove all dirt and/or particles that could lead to the locks operation or
condition being impaired. In particular ensure the magnetic surfaces are kept clean and clear of
debris which could impair performance.
• Every 3-months check the external sealing of the multicore cable connections and the overall
condition of the unit.
NOTE: In case of problems with the lock, contact SecurEx Technology’s Service Department
and arrange for the return of the unit to us for repair / service / replacement.
The Lock’s case is Torx security screw sealed. User access to the internal mechanism is NOT
required and opening the cover will VOID CERTIFICATION & may compromise the safety &
integrity of the product in its intended use.
