USER INSTRUCTIONS
CAUTION. Carefully observe all the following installation
instructions to ensure personal safety.
The device is not intended for use by persons (including children)
with reduced physical, sensory or mental capabilities, or lacking
experience and knowledge. Do not allow children to play with the
fixed controls and keep any remote-control units out of their reach.
Have installation checks performed periodically by qualified
personnel from a service centre authorised by the manufacturer. Do
not use if repair or adjustment is required.
CAUTION: if the power cable is damaged, it must be replaced by
qualified personnel from a service centre authorised by the
manufacturer.
CAUTION. Disconnect the power supply during cleaning or
maintenance operations. Do not use solvents or jets of water to
wash the appliance; the appliance should not be submerged in
water.
In the event of fault or malfunction, switch off the device at the main
switch. All repairs and adjustments (e.g. setting the stroke) must
only be performed by qualified personnel from a service centre
authorised by the manufacturer.
Always request exclusive use of original spare parts. Failure to
respect this condition could compromise safety and invalidate the
benefits contained in the warranty for the appliance. In the event of
any problems or queries, consult your agent or contact the
manufacturer directly.
The A-weighted sound pressure level is less than 70dB(A).
Carefully preserve these instructions after installation.

2. TECHNICAL INFORMATION FOR APPLICATION AND OPERATION
The K-LOCK electromechanical lock is a technical development for automatic locking of
windows, continuous facades and doors. It can be adapted to almost any type of profile in
aluminium, PVC or wood and performs the forward / backward movement of the sliding
accessory of a window or door.
Mounted by itself the device is an effective protection against intrusion, blocking the latch
of windows and doors, but it’s actually constructed to interface only with 24V chain
actuators of the INKA 356 series, even in the SYNCRO³ version, in natural ventilation and
smoke and heat exhaust systems (RWA). The reduced cross-section (just 25x25 mm)
allows recessed insertion in the profiles.
K-LOCK can be combined with the 230V~ actuators of the INKA 356 series (SOLO and
SYNCRO³ versions) by requesting, when placing the order for the actuators, the inclusion of
a small interface device.
The electromechanical lock is composed of a linear actuator that moves the locking hook
of the sliding accessory, with a selectable stroke of 18 or 36 mm. The easy-to-install
mechanisms can be recessed or mounted externally with just two screws.
In combination with the 24V actuators of the INKA 356 series, the device is certifiable
under standard EN 12101-2 – (Smoke and heat control systems – Part 2: Specifications
for natural smoke and heat exhaust ventilators).

8. ASSEMBLY INSTRUCTIONS
These instructions are intended for technical and specialized personnel, therefore
basic safety and working techniques are not discussed.
All operations for preparation, assembly and electrical connection must be carried out by
technical and specialized personnel; this will guarantee optimum performance and proper
operation of the electromechanical lock.
First check that these fundamental conditions are met:
The performance of the electromechanical lock must be sufficient to move the
sliding accessory without any obstruction whatsoever; the limits specified in the
product’s technical data table (page 5) must not be exceeded.
Check that the electric power supply used corresponds to that specified on the
“technical data” label attached to the machine and provided in the previous chapter.
Check that the electromechanical lock has not been damaged during transport,
first by visual inspection and then by powering it in one direction and the other.
Once the lock is installed, check that the latching hook of the pawl of the sliding
accessory is completely latched when the lock is closed and that after opening it’s
completely unlatched so as to allow the window or door to open without any
obstruction.
8.1. Preparation of actuator for assembly
Before starting assembly of the actuator, prepare the following material for completion,
equipments and tools.

that mechanical processing on machining tools, such as milling and drilling, is still
possible. Nevertheless, in case of assembly on a finished door or window frame, an expert
technician may be capable of applying the device as long as he has the necessar

10. START-UP OPERATIONS
In order to prevent damage, do not apply the 24V power supply voltage to the
system before having performed the start-up.
Strictly following the work steps below will guarantee a problem-free installation.
10.1. With actuator
 The connections between chain actuator and K-LOCK have been made and the
operation has already been bench tested; when opening the K-LOCK opens, goes to
18 or 36 mm (the hook moves towards the outside of the machine) and then the chain
of the actuator comes out. When closing, first the chain of the actuator re-enters
completely and then the K-LOCK goes to 0 (the hook moves towards the center of the
machine towards the power supply cable).
Caution: First the RESET procedure indicated in the instructions of the INKA
356 actuator should be executed.
 Keep the window unhooked from the chain.
 If necessary, operate on dip-switch 1 to correct the stroke; (see Chapter 7. “Setting
the dip-switches”).
 Supply power [24V ] and move the hook into the opening stroke-end position (18 or
36), then cut off the power.
 Hook up the window, i.e. check that the hook is inserted in the pawl of the sliding
accessory.
