The multifunctional security door lock
Functional description
The HZ-lock multi-locking system for burglar-resistant leaf doors fulfils all desired functions and
requirements. When the door closer moves the door to the closed position, it is first the lock latch that
engages in the opening in the strike plate and positions the door in the locking position; then the three bolts
(normally 1 bolt each at the bottom, middle and top of the door) are automatically extended by 20 mm (selflocking).
In the extended position the bolts are locked in the lock box to prevent them from being pushed
back. The lock box is made of hardened metal, making it difficult to drill open.
In the basic position, the door lever on the outside is not engaged. Normally, the door lever engages in
the lock mechanism when it is activated by the solenoid magnet, which in turn is controlled by the access
control system. As long as the magnet is live, the lever engages in the mechanism and will retract the lock
latch and bolts when it is operated. The bolts remain in their fully retracted positions, even if they do not
have to be fully retracted because of a wide gap between door and frame. In the case of a power cut or when
the door needs to be opened by the rescue service in an emergency, the door lever can also be engaged with
the appropriate safety key via the safety cylinder.
The internal door lever is always permanently connected to the lock mechanism. Therefore, the door
can always be opened from the inside using a single continuous hand movement on the door lever, thus
complying with the requirements of an emergency exit lock. Where exit control is also required, an
independent additional latch is fitted to the lock mechanism and the door is equipped with an escape door
opener and escape route controls.
The lock system has passed the required tests under DIN 18251 Class IV carried out at the Material Testing
Office in Dortmund and therefore complies with the requirements for a lock for enhanced burglar resistance
and high user frequency. In addition, the system has the benefit of verification of suitability for installation
in fire safety and smoke protection doors, as well as the test certificate for use as emergency exit lock in
accordance with EN 179 in combination with Glutz fire protection fittings. All commercially available
safety cylinders can be used with HZ-lock.

User instructions and maintenance recommendations
1. Entry
In the “locked” base position, the external door lever is detached from the lock mechanism and does not
engage when it is moved. When the access control system connects the power supply to the electromagnet
in the lock, the external door lever engages with the lock mechanism. When the lever is operated during
that phase it will retract the bolt and latch simultaneously. If the lever is not operated, the power supply will
again be disconnected and the lever disengages again automatically.
In the case of a power cut, a fault in the electric controls or for emergency opening by the rescue service, it
is possible to open the door purely mechanically with the appropriate cylinder key. To do this, turn the key
in the security cylinder in the opening direction until it stops, hold the key in this position and then, at the
same time, operate the door lever.
2. Exit
All locks marked “panic” on the forend always have the internal door lever fixed connected with the lock
mechanism. Operating this internal door lever will always open the exit. In special cases it is also possible for
a green emergency button to be installed near the door; in this case the emergency button has to be operated
before the exit is released for opening; this usually triggers an alarm.
3. Locking
The lock automatically locks the door with three bolts after each locking action. It is therefore not necessary
to turn the key in the cylinder. However, it is necessary for the bolts and latch to be able to enter the respective
openings in the strike plate or in the frame without obstruction so that the automatic locking mechanism
can work properly. A door position contact and a bolt position contact are fitted in the electrical lock. These
make it possible to monitor correct locking – something that is highly recommended.
4. Maintenance
The following regular maintenance checks are recommended at intervals of not more than one month; these
are to be carried out by the operating organisation or a third party.
a) Cleaning with cleaning agents that do not contain corrosive substances.
b) Inspection and functional check of emergency exit lock in order to ensure that all parts of the locking
mechanism are functional and in a satisfactory operating condition.
c) Ensuring that the openings opposite the locking devices are not blocked.
d) The lock latch, the control latch and the bolts have to be lubricated at least twice annually – more often
depending on usage – without opening the lock box, using a little grease (no spray). It is not permitted to
spray substances into the inside of the lock. The door closes more easily and without noise if the sloping
surface of the latch is always lightly greased (the security cylinder has to be removed before it can be
sprayed for maintenance purposes).
e) Checking that no additional locking devices have been installed since the first installation of the door.
f ) A check should be carried out annually that all components of the system are in accordance with the list
of approved components originally supplied with the system.
g) With heavy use of the door, a revision of the door lock is indicated after 2 to 3 years in order to ensure
that the system functions reliably at all times. We can supply replacement locks where required.

Installation instructions II
Preliminary notes
• For these products to comply with EN 179, their safety features are essential. No modifications are
permitted except those described in these instructions.
• HZ-lock is suitable for door elements up to 200 kg and for burglar-resistant door elements up to WK4.
• HZ-lock with panic function: ensure that your burglar-resistant door construction provides resistance
against impact and possible drilling when exposed to risk so that no large enough opening can be made
to reach through, and that the door closes against a threshold at the bottom.
1. Preparing the door
• Cut the mortices for the lock in accordance with the drawing; provide lateral support for the lock box if
appropriate; where specified, recess the forend to a depth of 6 mm.
• Clean all mortices and profile tubes. Remove any sand!
• The gap between the lock forend and the strike plate must be between 3 and 6 mm; drill the holes for the
lever spindle and safety cylinder.
2. Frame recesses
The door is only positioned by the lock latch. The bolts must be able to engage in the strike plate openings
without obstruction (at least 1 mm clearance on both sides, bolt protrusion = 20 mm). The control latch
must not enter into an opening but must touch the frame or strike plate when it protrudes.
3. Fitting the lock
Cut the forend at the top and, if required, at the bottom, to the exact length required.
Allow the bolts at the main lock to extend by holding the lock latch pushed in and, at the same time, retaining
the control latch below. When releasing the lock latch, the bolts extend.
In order to connect the lower part of the lock and the upper forend extension, carefully insert the two
connection rods of the forend extension into the guide grooves at the forend of the main lock until they
engage automatically; proceed to place the Ω cut-outs of the forend profiles into each other.
We recommend that you first fix the top forend extension loosely to the door with the top screw, then
connect the main lock from below to the forend extension; let the connection rods engage and insert the
lock in the prepared mortice recesses. It is imperative that the connection rods are not bent in the forend at
the connecting point when assembling the lower part of the lock and the upper forend extension, as the lock
will not function with bent connection rods. No guarantee will be upheld where the connection rods are
bent.
Insert the plug – do not retract the cable on the hinge side – tighten the screws.
Should it be necessary to disengage the upper forend extension, extend the bolts and push a pin (approx. 3
mm) into the hole in the forend above the lock latch and simultaneously carefully pull the two parts apart.
4. Fitting the cylinder
Depending on the cut-out in the lock box, any profile cylinder to DIN 18252, or round Kaba/Keso
cylinder, can be fitted. The locking bit can be in any position. The breakthrough for the safety cylinder in
the door leaf must be sufficiently large. No part of the cylinder must make contact with the door leaf. To fix
the cylinder, insert an Allen key (3 mm) into the hole in the forend underneath the bolt, approx. 60 mm
deep into the fitted forend screw and use it to tighten the screw. Make sure that the cylinder is correctly
centred in the lock and that the cylinder cam can function properly. Never operate the door lever or cause
the bolts to extend while the Allen key is still in place.
5. Fitting the protection fitting
HZ-lock has been tested in combination with Glutz protection fittings ES-2 and ES-3 for compliance with
EN 179. It is important that both door levers are fitted to the plates so that they can turn freely but are firm
and stable (. The split lever pin does not hold the set in place and is not capable of withstanding tensile
stress. When using roses, the stress on the follower parts would be too great. In this case we do not give
any warranty for the lock system.

For drilling the holes it is preferable that you use the drilling template from the manufacturer of the
protection fitting; this should be positioned at the follower of the lever and at the cylinder cut-out. Start
drilling on both sides, remove the lock, drill the door leaf fully on both sides making sure not to damage the
electrical supply cable! Clean the lock mortices and refit the lock.
Prepare the screws to the correct length. When tightening the screws it is important that neither the lever
spindle nor the cylinder in the lock get jammed. The door leaf must not be contracted; where necessary
spacing sleeves must be provided.
6. User instructions and maintenance recommendations
The building owner/user must be instructed about the functions of the unit and the handing over of the
enclosed instructions with maintenance recommendations must be confirmed in writing.
The attached sticky note advising about opening the door with the key must be attached to the outside of
the door until the above user instruction has been carried out.

Reversing the panic function
from the hinge side to the opposite side, and vice versa
Tools required:
1 door lever spindle, 9 x 9 mm
1 Allen key, 1.5 mm
1 half or double safety cylinder with key
(HZ-lock: changing from disengaged position to panic function from point 7 needs
an M2 x 5 mm Allen bolt)
Procedure:
1. Clamp the lower part of the lock to the workbench with the panic function facing
upwards.
2. Remove the round sticker with the HZ logo next to the lever follower; this will
reveal a round opening in the lock box.
3. Use the door lever with 9 x 9 mm spindle to operate the follower on the panic side
until the bolt head with the hexagonal socket appears in the lock box opening;
hold the follower in this position.
4. Use the 1.5 mm Allen key to release and remove the bolt. Make sure that the
follower stays still until the bolt has been removed so that it does not fall into the
lock housing.
5. The door lever can now be released.
6. Turn the lock over (disengaged lever follower is now uppermost).
7. Remove the round sticker with the HZ logo next to the follower; this will reveal a round opening in the
lock box.
8. Insert the safety cylinder, turn the key in the opening direction until it stops and hold in this position.
9. Operate the follower simultaneously with the door lever until the threaded hole appears in the opening
of the lock box; hold in this position.
10. Carefully insert the cylinder head bolt previously removed and tighten normally (do not use excessive
force!). Make sure that the follower stays still and that the bolt does not fall into the lock housing.
11. Re-attach the two stickers to close the openings against any dust ingress.
In our production we test each individual lock with a PC control system to ensure its proper function. The
serial number includes a code of the function tested. If the sticker is damaged and subsequent modification
has been carried out, we are unable to uphold our guarantee.
In case of doubt, please contact the manufacturer in the first instance. An explanatory telephone conversation
is normally cheaper than the cost of repairing a lock.

Removing the panic function bolt
Tools required:
1 door lever spindle, 9 x 9 mm
1 Allen key, 1.5 mm
Procedure:
1. Clamp the lower part of the lock to the workbench with the panic function side
uppermost.
2. Remove the round sticker with the HZ logo on the forend side of the lever
follower; this will reveal a round opening in the lock box.
3. Use the 9 x 9 mm spindle to insert the door lever into the follower.
4. Operate the follower with the door lever until a small cylinder head bolt with
hexagonal socket appears in the lock box opening; hold the follower in this
position.
5. Carefully release and remove the cylinder head bolt using the 1.5 mm Allen key.
Make sure that the follower stays still and that the bolt does not fall into the lock
housing.
6. Re-attach the sticker to close the opening against any dust ingress.
In our production we test each individual lock with a PC control system to ensure
its proper function. The serial number includes a code of the function tested. If the
sticker is damaged and subsequent modification has been carried out, we are unable
to uphold our guarantee.
In case of doubt, please contact the manufacturer in the first instance. An explanatory telephone conversation
is normally cheaper than the cost of repairing a lock.
Control of electrical feedback
The correct functioning of the door monitoring system (bolt position contact and door position contact)
depends on:
• All three bolts being fully extended.
• The permanent magnet being correctly positioned in the frame (correct dimension under the lever axis,
depending on the magnet fitted).
• The distance between magnet and forend not being more than 5 mm.
• The fitted magnet not being in contact with the steel components of the strike plate or frame.
Checking
1. With the door open: push in the main latch, retain the control latch, let go of the main latch, the bolts
extend
2. Hold the permanent magnet at a distance of max. 5 mm from the forend, 125 mm below the lever axis.
If the feedback contacts are now closed, feedback in the lock will work satisfactorily. All conditions listed
above must be checked and corrected if necessary.
If feedback is still not received: remove the lock from the door, check the plug and supply cable (there may
be damage from drilling for the installation of the protection fittings).
If these checks do not lead to the desired success, the lock must be replaced or repaired in the workshop
(replacement of the printed circuit).

HZ-lock with additional latch
The HZ-lock with additional latch is used for the following applications:
• burglar-resistant doors
• doors on escape and rescue routes
• access control or remote control operation
• exit control and/or security lobby locking
An additional latch is integrated in the upper forend extension. This works independently of the lock
mechanism. It requires the installation of a matching escape door opener (effeff 331) in the frame. On the
inside a door terminal with emergency button and, if required, escape route control, is installed next to the
door.
Security lobby control
The escape door opener will cause the locking of the doors on both sides of the lobby, because the inner
door lever is fitted with panic function, i.e. operating this lever will cause the three bolts and the lock
latch to retract but not the additional latch. As soon as one door is opened, the escape door opener of the
opposite door is switched live via the security lobby control system. It is also possible to use the door lever
contacts fitted in the lock for the security lobby control system.
In an emergency, the escape door openers are unlocked via the fire alarm system or the emergency button.
The cylinder contact installed in the lock can be used for unlocking the escape door opener for the rescue
service.
Exit control
Once the authorisation has been recognised, the entry reader on the outside releases electricity to the
coupling magnet in the lock and, at the same time, unlocks the escape door opener via the “short-term
unlocking” terminal at the escape route control system.
The exit reader only unlocks the escape door opener via the “short-term unlocking” function; the door
is opened using the mechanical panic function. In an emergency, the escape door opener is released by
pressing the emergency button.
When a rescue service engages the external door lever mechanically using a key, a switch contact in the
lock will operate at the same time which interrupts the power supply to the escape door opener.
Advantages
• Meets all Building Control requirements for escape and rescue routes.
• The escape door opener can be installed concealed, unlike flat magnets which may also reduce the clear
height of the opening.
• The additional locking point above the main lock is better than one at the top edge of the door.

Option: Electrical lock operation block
An additional lifting magnet is attached to the top of the main lock box which can be used to block the
three bolts from extending for as long as the lift magnet coil is live.
When this additional electromagnet has been switched live, the three bolts and the latch are retracted
either by the engaged external door lever, or the internal door lever. When the door closes, the latch will
engage in the trap but the three bolts remain retracted. If the power supply to the magnet is interrupted,
the bolts will extend when the door is closed.
For doors with an automatic drive, an electric door opener is installed as counterpart to the lock latch.
Solenoid coil: 12 or 24 VDC, 100% E.D., 4.8 Watt
Note: this version is not the same as that covered by the general Building Control test certificate.
