1. DESCRIPTION
The COBALT is a motor driven low voltage electric lock designed to secure commercial and residential swing
through doors. It is supplied with a matching strike plate and can be surface mounted with the aid of available
accessories, or installed into a mortise for a concealed solution. The lock has been designed to address the two
biggest issues in concealed electric locking today;
1. The ability to ‘pull’ a door into alignment even if the door has not closed in a central position.
2. The ability to release when requested even if there is excessive load on the door.
The design of the COBALT is unique as it has two motors which independently operate two locking pins. These
dual bolt pins offer extra strength but more importantly ensure the door can be secured even when the door has not
closed in the correct position. This is achieved by the lock sensing which direction the door is closing from and
activating the appropriate bolt pin to ‘grab’ the door and pull it into alignment before the other bolt pin activates. A
door that is 8mm off alignment in either direction (16mm total window) will be secured with the COBALT.
With the door secured and locked the COBALT can be given an unlock signal and it will instantly unlock. If the door
is loaded (pre-load) when the unlock signal is given the COBALT will still unlock, even with loads in excess of
100Kg on the door. Critically the ability of the COBALT to instantly release with excessive pre-load on the door
even occurs in the event of a power failure if the lock is configured as fail safe.
Additional features of the COBALT are;
Multi-voltage input (12-24VDC)
Very low current consumption
Door position and Bolt position monitors
High physical strength –10,000N holding force
Fail safe / fail secure on site conversion with the re-positioning of a single jumper
2. PRODUCT UNBOXED
Along with the COBALT and matching strike there are also 10G Self
Tapping and M5 Machine Screws supplied. Four fitting tabs are also
enclosed and can be used in conjunction with the M5 screws for
recessing the lock or strike plate to metal doors and frames.
The 7 way wire loom supplied is used to ease installation as the wiring
can be done without the lock being installed until the very end.

4. PRE - INSTALLATION ASSESMENT
4.1 Mechanical
The first decision regarding installation is whether the COBALT will be mortised or surface mounted to the door /
door frame. Mortise installation ensures a discrete solution as the lock and strike plate can be embedded into the
door and frame, however in some instances this is not possible. Glass doors for example require surface mounting
which is done with the aid of the YD30 housing. Whichever method is chosen it is important that the lock and strike
plate are aligned correctly. The strike plate has two openings to accept the dual bolt pins and centring these
openings with the bolt pins will ensure correct operation.
The COBALT can be installed vertically or horizontally but is not designed to be mounted in a floor cavity
firing upwards or in a wet environment.
4.2 Electrical
The first consideration is to establish where to run the wires and decide on what feedback is required from the lock.
There are a total of seven available connections; three are compulsory power connections whilst the remaining four
provide optional door and bolt position feedback. These optional connections can be integrated into access control
or alarm systems to provide full monitoring.
The correct gauge of wire needs to be chosen as voltage drop across the power wires (+ and -) can limit the locks
operation. For all the remaining connections, a lower gauge wire can be used as these are only signal wires. The
following chart shows the maximum distance that the power supply can be away from the lock, assuming the power
supplies output 12VDC or 24VDC:

5. INSTALLATION
Two installation examples are detailed on the following pages; mortise and surface, however any combination of
the two can be achieved. Whichever installation method is chosen it is vital to ensure that the lock face plate
and the strike plate align correctly and the gap between the lock face plate and strike plate does not
exceed 8mm when the door is closed.
5.1 Mortise Installation
A typical mortise installation is described on the flowing page, with the lock fitted into the door frame and the strike
plate secured into the door. It is possible to install the lock into the door and the strike plate into the frame however
with this method running wiring to the lock requires additional work.

5.1.1 Cutting the mortises
Referring to the dimension drawings in Section
3; mortises are cut into the door and door frame
suitable to fit the strike plate and lock. Wooden
doors and frames require full mortises where
metal doors and frames, being hollow, often
only require a single rectangle cut-out to
accommodate the lock face plate or strike plate.
For these installations the supplied fitting tabs
can be used to secure the lock and strike plate
in place.
The mortise behind the lock body needs to
have enough space to accommodate the
wire connections.
5.1.2 Wiring the lock
Wires are run from the power supply to the lock.
A hole needs to be drilled in the back of the
mortise to bring the wires out and a connection
can be made to the supplied wire loom which in
turn plugs into the lock. The jumper needs to be
positioned for fail safe / fail secure configuration
as per the instructions on the lock cover.
The Red, Black and Blue wires are essential
connections whilst the Violet and White are
optional. Detailed wiring instructions can be
found in Section 6.
5.1.3 Fitting the lock and strike plate
The lock is slid back into the mortise, making
sure that the wiring integrity is maintained and
secure in place with the supplied 10G self
tapping screws.
Before the strike plate is installed the fitting tabs
are secured in behind the cut-out using the
supplied M5 machine screws. The strike plate is
then placed into the cut out and the remaining
M5 screws are used to secure it.

5.1.4 Checking the operation
With the lock and strike installed and wiring
complete the door is closed to check the
alignment and operation. The key area for
alignment is the bolt pins; the pins are designed
to touch the leading edge of the strike plate
hole to pull the door in, but they cannot be
allowed to touch the sides of the hole as this
will limit their unlocking ability. If they rub or
touch the side of the strike plate hole, either the
lock or strike plate needs to be re-positioned.
5.2 Surface Installation
By using a YD30 housing, the lock and or strike plate can be surface mounted to the door or door frame eliminating
the need for cutting mortises. Housings are available with adhesive tape supplied for easy application to glass
doors in addition to having screw hole mounting points for wood and metal doors.
5.2.1 Securing the lock housing to wood
Before fitting the housing, determine exactly
where the wiring will enter the housing and drill
one or two 8mm holes through the housing wall.
Ensure the holes are on the housing face that
goes against the wooden frame. Push the
supplied grommet(s) into the drilled hole(s). The
two 10G Hex head self-tapping screws supplied
with the housing can then be screwed into the
wood but not tightened. The two keyhole
shaped cut outs in the housing fit over these
screw heads which are tightened with a ring
spanner once the housing is in place.
5.2.2 Wiring the lock
Wires are run from the power supply to the lock
through the drilled hole(s) in the housing. A
connection can be made to the supplied wire
loom which in turn plugs into the lock. The
jumper needs to be positioned for fail safe / fail
secure configuration as per the instructions on
the lock cover.
The Red, Black and Blue wires are essential
connections whilst the Violet and White are
optional. Detailed wiring instructions can be
found in Section 6.
The bolt pin touches the leading edge of
the strike plate hole but there needs to be
clearance around the sides of the hole.

5.2.3 Fitting the lock into the housing
Once wired, the lock is slid into the housing and
secured in place with the supplied M5 machine
screws. Make sure that the wiring integrity is
maintained as the lock is screwed in place.
5.2.4 Fitting the strike plate housing
to glass
For simple application to glass the YD30
housing is supplied with self-adhesive tape.
With the backing removed the housing can be
applied directly to the glass. A flat stainless
steel dress plate is fitted on the opposite side of
the glass to give a clean finish. The protective
coating on the dress plate can be removed
once it is in place.
5.2.5 Fitting the strike plate into
the housing
The strike plate is placed into the housing and
secured in place with the supplied M5 machine
screws.
5.2.6 Checking the operation
With the lock and strike installed and wiring
complete the door is closed to check the
alignment and operation. The key area for
alignment is the bolt pins; the pins are designed
to touch the leading edge of the strike plate
hole to pull the door in, but they cannot be
allowed to touch the sides of the hole as this
will limit the unlocking ability. If they rub or
touch the side of the strike plate hole, either the
lock or strike plate needs to be re-positioned

6.3 Jumper position
The fail mode of the COBALT is factory set as Fail Safe, i.e. in the event of a power cut the COBALT will unlock.
Before the lock is installed this can be changed to Fail Secure by repositioning the jumper located next to the 7-way
plug on the end of the lock. Select the desired jumper location as indicated:
7. OPERATION
7.1 Fail Safe Operation
Assume the lock is installed and wired, the door is open and there is voltage applied to the BLUE wire. As the door
closes the COBALT senses the door approaching and activates the appropriate bolt pin to pull the door into centre
alignment. Once the first bolt pin has fully extended, the second bolt pin activates and drives to its full extension. If
the door closes to a centre aligned position quickly then both bolt pins activate at the same time rather than one
leading the other. The Bolt Position and Door Position monitors will have changed state as the door is moved into
place and secured.
To unlock the door, voltage is removed from the BLUE wire. The COBALT will immediately release and will do so
even when significant load is being applied to the door. With the door now open the Bolt Position and Door Position
monitors change state again. The COBALT will remain unlocked as long as the door is open but will instantly re-
lock when voltage is applied to the BLUE wire and the door is closed.
In the event of a power failure, voltage is removed from the BLUE wire and the COBALT unlocks.
7.2 Fail Secure Operation
Assume the lock is installed and wired, the door is open and voltage is removed from the BLUE wire. As the door
closes the COBALT senses the door approaching and activates the appropriate bolt pin to pull the door into centre
alignment. Once the first bolt pin has fully extended, the second bolt pin activates and drives to its full extension. If
the door closes to a centre aligned position quickly then both bolt pins activate at the same time rather than one
leading the other. The Bolt Position and Door Position monitors will have changed state as the door is moved into
place and secured.
To unlock the door, voltage is applied to the BLUE wire. The COBALT will immediately release and will do so even
when significant load is being applied to the door. With the door now open the Bolt Position and Door Position
monitors change state again. The COBALT will remain unlocked as long as the door is open but will instantly re-
lock when voltage is removed from the BLUE wire and the door is closed.
In the event of a power failure, voltage is removed from the BLUE wire and the COBALT locks if the door is closed.
