Description
For secure head retention in all applications the top M8 head xings must be used.
Fortress provides a single action escape release function from inside a guarded
area through the use of a head and handle application. This unit may be installed
in left or right orientation to hinged doors. The tongue incorporates a self-aligning
feature to cater for misalignment on guards. Simply turning the red handle will open
a locked guard from the inside and open the safety contacts. Releasing versions of
other modules are the type that MUST be used in conjunction with this module.
• Intuitive single action escape release handle.
• Escape release activation releases tongue and opens safety contacts.
• Handle includes Lock-Out for 4 padlocks of 8mm diameter.
• 10kN retention force.
• Stainless steel tongue is ideal for fast and frequent access.
• 2 mounting position at 180° increments allowing on site handing change
possible.
• Misalignment tolerance of +/- 10mm with +/- 4° angular misalignment.
• Security tool reset after escape release actuation or auto reset function available.
• Head can be tted with lock-out device for additional lockout capability.

3. Position the handle so the adjustable tongue is in central position vertically position to compensate for movement of
guarding in either direction overtime.
Note: The distance between the interlock and handle mounting points should within the specied range to allow the tongue to
fully insert into the interlock mechanism while ensuring the door can be opened and closed without the handle body making
contact with the unit head.
The unit has been designed to be mounted in 3 dierent ways; onto extruded aluminium section, at plate and onto plates or
guards greater than 25mm thick.
Extruded Aluminium Section
• The handle will be delivered in this conguration.
• Cut a Ø50mm hole for the handle boss of the red escape release handle to go through the guard in the appropriate
location.
• Fix the handle to the Aluminium section using 2 x M6 T-Nuts and 2 x M6 Bolts.
• Use a third M6 bolt to attach the rear mounting to the guard.
• A spacer may be required for the rear xing.
Figure 7 & 8:
Plates and Guards up to 25mm thick
• The handle will be delivered in this conguration.
• Cut a Ø50mm hole for the handle boss of the red escape release handle to go through the plate / guard in the appropriate
location.
• Cut 3 x M6 threads into plate / guard using the panel cutout dimensions given below in Figure 9.
• Insert red escape release handle through Ø50mm hole and secure handle to plate / guard using 3 x M6 Bolts.

Figure 10:
Resetting an I6 or I7 type Head
After an escape release operation, the head will latch and keep the guard interlocking device in an unlocked and open state.
After ensuring the guarded area is unoccupied and it is safe to do so, the head can be reset using the following steps;
1. Close the guarding door and, using the exterior silver access handle, extend and re-insert the tongue into the head.
2. Insert the supplied reset key into the keyhole aperture of the I6 or I7 type head and turn it one complete revolution - Note:
The reset key will only turn one direction and only in complete revolutions. If the key free position is passed, then another
turn will need to be completed before the reset key can be removed.
3. Remove the reset key after reset operation and keep in a secure place under management control.
4. Test that the reset has been successfully completed, by placing the complete device into its ‘Locked’ state and ensuring
the exterior (silver) handle is locked and secure.
Resetting an A6 or A7 type Head
The A6 and A7 type heads require no additional resetting procedure after an escape release
operation.
Closing the guarding door and re-inserting the tongue into the head using the exterior silver
access handle will return the device into its ‘Locked’ state.
Auxiliary Unlocking Mechanism
In the event of power failure, the guard locking may be overridden in the normal manner.
Mechanical Commissioning
The complete guard installation should be tested prior to use.
1. Insert the tongue into the head. It must lock in position.
2. Remove the locking means, and check that the tongue releases when turning the silver handle breaking the safety circuits.
Check the tongue locks in place again when reinserting into the head.
3. Check that with the locking function in place, that the red handle will turn and open the door breaking safety circuits
(which stay broken on closure until reset). Then reset the unit, by evacuating the guarded area, using the silver handle
close the door, inserting the tongue fully. Then is I6 / I7 head insert the reset key and rotate 360 degrees and remove the
reset key. Check that the silver handle is now locked in place and the safety circuits closed.
Warning: This device does not contain the Machine Reset or Restart facility after an escape or auxiliary release of
the guard locking. Addition measures are required to achieve the reset of the machine system.
