PURBROOK INSTALLATION, OPERATION AND MAINTENANCE INSTRUCTIONS
THESE INSTRUCTIONS CONTAIN IMPORTANT SAFETY AND MAINTENANCE INFORMATION AND MUST BE PASSED
TO THE END USER.
The safety features of this product are essential to its compliance with EN179. The suppled keeps should be used to ensure
compliance. No modifications, other than those described in these instructions, are permitted.
No other devices that secure the door in the closed position should be fitted to a door set incorporating this device.
Routine maintenance is vital to ensure the continued performance of the locking systems and compliance with relevant
standards. Refer to section 10 for maintenance instructions.
Before fitting this Surelock device, read these instructions carefully and verify the door construction allows for the use of
this device. If in doubt, please contact our technical sales department for advice.
The system these instructions are supplied with is designed to fit inward and outward opening steel or timber fire and non-fire
doorsets with door leaf maximum dimensions of 2500mm (8’ 2½”) height and 1300mm (4’ 3¼”) width, with maximum mass of 200kg
(440lbs) and maximum door distortion of 5mm (3/16”). The door leaf and fixing method should be of sufficient strength that it is not
possible to pull out the fixings by applying 1000N (225lbs) force. For security / blast doors, it is recommended that core fixings are
used on timber doors or fixings are tapped into 8mm steel plate to give equivalent strength to the M8 fixings provided. It is not
recommended that emergency exit devices are fitted to hollow core composite or timber doors. The door must be hung correctly, be
free from binding.
When fitting to a fire door, the fire certification of the door should be examined to ensure the device is suitable for use on that door.
Where double doorsets have a rebated meeting stiles and self-closing devices, a door coordinator complying with EN 1158 should be
fitted to ensure the correct closing sequence of the doors. This device is not intended for use on double swing doors.
If a door closing device is to be used, care should be taken to ensure this does not to impair the use of the doorway by the young,
elderly or infirm.
Category 2 (standard projection) emergency exit devices should be used in situations where there is restricted width for escape, or
where the doorsets are not able to open beyond 90°.
Where an emergency exit device is designed to be fitted to a glazed door, it is essential that the glazing is tempered or laminated
glass.
When fitting emergency exit devices to doors on raised or recessed surfaces, consideration should be given to minimising potential
safety risks, such as trapping fingers or clothing. Care should be taken to ensure that any seals or weather-stripping, do not inhibit the
correct operation of the panic exit device.

PURBROOK INSTALLATION, OPERATION AND MAINTENANCE INSTRUCTIONS
1. Ensure the door leaf is hung correctly and opens freely. Position the template accurately on
door as indicated below. Note; this allows for 6mm (1/4”) gap between the edge of the lock
and the strike for the standard keep plate or 10 mm (3/8”) for roller keeps. The gap may be
increased to allow for door swing.

PURBROOK INSTALLATION, OPERATION AND MAINTENANCE INSTRUCTIONS
2. Drill holes in door to suit chosen fixing method.
For timber doors, core fixings are recommended for maximum security and fire performance.
For metal doors, machine screws going into an 8mm (5/16”) tapping plate within the leaf are
recommended for maximum security and fire performance.

3. If required, fit the external cylinder / cylinder guard (GSS) as directed in separate instructions
supplied. Note, if fitting a cylinder, the position indicated on the paper template is the centre of
the operating bar, not the centre of the cylinder body. The operating bar will need to be cut to
length to engage the lock by 4mm to 5mm (5/32” to 7/32”).
4. The lock is supplied as non-handed with emergency escape both sides. To disable the
emergency escape from one side (for example, to prevent entry from the outside when the
door is locked or to require use of a thumbturn to exit), fit the locking bracket into the slot in
the face of the lock of your chosen handing (for example, towards the outside of the door).
5. Assemble the lock as shown below.
Restraint strike adjustable
using small flat blade screw

Locking bracket inserted on external side.
The locking bracket may also be inserted on the
internal side if emergency escape is not required.
Locking bracket screw must be retained with
Locktite.
Anti-drill discs

PURBROOK INSTALLATION, OPERATION AND MAINTENANCE INSTRUCTIONS
6. If using the Purbrook Anti-Drill mount plate, assemble as shown below, ensuring the textured
side of the anti-drill insert is to the attack side.
Note: The Purbrook Anti-Drill plate should be used in conjunction with the Surelock GSS
cylinder guards
7. Adjustment of restraint.
•First, fully wind the restraint in.
•Then wind the restraint out until it just fires when the door closes.
•Give the restraint one more turn out.
8. Check the lock releases when the forces detailed below are applied to the operating devices:
•Lever handles - 70 N (17.7 lbs) (maximum) applied to the handle at a distance
100mm (4”) from the spindle in a downwards direction.
Ensure that any weather seals fitted to the complete door set do not inhibit the correct
operation of the emergency exit device. Check that the bolts, when in the withdrawn position,
do not prevent the door swinging freely.
9. If installed in the European Union, a sign which reads “Rotate handle to open” as appropriate
(not supplied), or a pictogram should be provided on the inside face of the leaf immediately
above the operating device or on the operating device if it has sufficient flat face to take the
size of lettering required. The surface area of the pictogram should be not less than 8000mm2
(e.g. 90mm by 90mm or equivalent area) and its colours should be white on a green
background. It should be designed such that the arrow points to the operating element, when
installed.

10. Maintenance instructions
It is recommended that the following routine maintenance checks be undertaken at monthly
intervals:
•Inspect and operate the lock to ensure that all components are in a
satisfactory working condition and the release forces are within those detailed
above.
•Check periodically that no additional locking devices have been added to the
door since its original installation
•Ensure that all keeps (sockets) are free from obstruction.
•Check that all fixing screws and retaining pins are in place and tight, and that
the equipment is correctly adjusted.
•Lubricate cylinders (if applicable) with an appropriate manufacturers lubricant
(not oil).
•Ensure that the bolts are in line with keeps (sockets).
•Ensure restraint is operating correctly and adjust if required.
•Periodically lubricate the device by spraying GT85 lubricant or similar into the
locking bolt and latch snib openings.
Cleaning: Clean using a damp cloth, using mild detergent if necessary. Do not use
aggressive solvents or cream cleaner. In highly corrosive environments wipe with a damp
cloth, dry and then wipe with an oiled cloth.
Annually or 50,000 cycles (whichever is sooner):
•A Surelock McGill trained engineer should service the equipment.
•Any item noted to have excessive wear should be replaced.

13. Wiring diagrams
Note: All systems are supplied with a 12 core cable. Note: the functions fitted within the lock
are dependent on the enhancements specified. Wires should be tinned.
Surface mounted cable routing:
Remove cable cover plate
and drill 7mm hole as shown.
Ensure no sharp edges
Cable route through door:
Maximum voltage through monitoring switches = 50V
Maximum current through monitoring switches = 500mA
Maximum solenoid voltage/current:
12V systems = 14V max, use 2.5A fuse
24V systems = 28V max, use 2.5A fuse
/ current through solenoid = See table below
Note: Use fuse or current limiter to ensure current limits are not
exceeded
