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

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).

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.

OPERATION…

OPERATION

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.
