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 Check that the bolts, when in the withdrawn position,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.
