1. DESCRIPTION

The YD25K is a solenoid operated dead bolting lock with manual key override suited for commercial or residential

doors. In fail securemode, the use of electronic access control can be bypassed completely for a traditional lock and

key. It is supplied with a matching strike plate and can be surface mounted with the aid of accessories or installed

into a mortise for a concealed solution.

Integrated electronics provide complete control over the lock and offer an array of features;

Multi–voltage input (12-24VDC)

Multiple locking / unlocking attempts

Adjustable timed re-lock

Current reduction circuitry

Door position and bolt position monitors

High physical strength –10,000N

2. PRODUCT UNBOXED

The YD25K is supplied with four 10G x 1” csk self-tapping

screws for fitting the lock and strike plate. They are

suitableformountinginboth aluminium andwoodendoors

and frames. Also included are eight M5 x 10 Machine

Screws. The YD25K is also supplied with an M5 x 30 csk

screw for the key cylinder.

The mounting holes in the lock face plate and strike plate

are ø 5.2mm so any 10G or 5mm screw can be used.

4. PRE-INSTALLATION ASSESSMENT

4.1. Mechanical

The first decision regarding installation is whether the YD25K 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 the

lock which is done with the aid of the YD25K housing. Attention must be made to where the key cylinder will be

situated and if it is easy to access with a key for the manual override operation.

Page 6

Whichever method is chosen it is important that the lock and strike plate are aligned correctly. This is achieved when

the top of the lock face plate aligns with the top of the strike plate. It is also important that when the door is closed

the gap between the lock and strike plate does not exceed 6mm otherwise thelock will not sense the strikes position

resulting in incorrect operation.

The YD25K 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 eleven available connections and for a fully featured lock it is compulsory to connect three with

the other eight providing feedback. Alternatively the lock does operate with reduced features on two compulsory

connections and eight optional.

The three essential connections are; Positive (+), Negative (-) and Key Position Control (CL). The eight optional

connections provide feedback about the lock status; Door Position and Bolt Position. If desired, wires can be run

from these connections to integrate into access control or alarm systems to provide full monitoring.

Finally the correct gauge of wire needs to be chosen as when connecting the power wires (+ and -) to the lock,

voltage drop across these wires can limit the lock operation. For all the remaining connections, a lower gauge wire

can be used as these are only signal wires.

The following chart shows the appropriate wire gauge for a range of distances between the lock and power supply

assuming the voltage measured at the lock is within the range of 12-24VDC ±10%.

5. INSTALLATION

Two installation examples are detailed on the following pages however any combination of mortise and surface

mounting 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 locks face plate and the strike plate does not exceed 6mm

when the door is closed.

5.1. Mortise installation

A typical mortise installation is described with the lock fitted into the door frame while the strike plate is secured to

the door. It is possible to install the lock into the door and the strike plate to the frame however running the wiring to

the lock can be difficult.

Page 7

5.1.1. Cutting the mortises

Using the supplied lock dimensions a mortise

is cut in the door frame that is suitable to

house the lock. An appropriately sized hole is

then cut through the wall or door to give room

for the installation of the key cylinder. An

appropriate sized mortise is then cut for the

strike plate and hole to accept the bolt pin are

drilled. The lock pin hole behind the strike

plate needs to be free from debris and deep

enough to allow the lock pin to fully extend

when locked.

5.1.2. Wiring the lock

Wiresarerun outfrom the back of themortise

and following the connection guide on the

locks cover, connected to the lock.

Detailed wiring information can be found in

Section 6 - Wiring.

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 secured with the supplied mounting

screws. Likewise the strike plate is fitted into

its mortise and secured in place. The euro

style key cylinder can be installed and

screwed in place with the supplied M5x30

csk. screw.

5.1.4. Checking the operation

With the lock and strike installed and the

wiring complete the door is closed to check

alignment and operation.

5.1. Surface installation

By using a YD25K housing the lock and or strike plate can be secured to the door or door frame eliminating theneed

forcuttingmortises. Housings are availablewith adhesive tapesupplied foreasy applicationto glass doorsin addition

to having screw hole mounting points for wood and metal doors.

5.1.1. Securing the housing to wood

Two 10G x 1” pan head self-tapping screws and

two stepped washers are supplied with the

housing and can be screwed into the wood door

frame. The housing has two holes that accept

the stepped washers from the inside and once

the housing is in place the screws can be

tightened with a #2 Phillips head screwdriver

through the outside holes. One secured, the

included C brackets can be inserted under the

lock mounting holes to block the exposed hole,

with theholeintheC bracketspositioneddirectly

under the lock mounting holes.

5.1.2. Wiring the lock

The wires will need to be run into the housing to

connect to the lock. The position of the hole is

determined at installation time by finding exactly

where the wiring will enter the housing, and drill

an 8mm hole through the housing wall. The

housing is supplied with one grommet, which

can be pushed into the drilled hole to protect the

wires form the sharp edge of the hole.

Detailed wiring information can be found in

Section 6 - Wiring.

Page 9

5.1.3. Fitting the lock

Once wired, the lock is slid into the housing and

secured in place with the M5 X 16 csk screws

that were supplied with the housing. These

should also secure the C brackets in place.

5.1.4. Securing the housing to glass

For simple application to glass the YD25K

housings are supplied with self-adhesive tape.

With the backing removed the housing can be

applied directly totheglass. A flat stainless steel

dress plate is fitted on the opposite of the glass

to give a clean finish.

5.1.5. Fitting the strike plate

The strike plate is placed into the housing and

secured in place with the supplied M5 x 16 csk

screws.

5.1.6. Checking the operation

With the lock and strike installed and the wiring

complete the door is closed to check alignment

and operation.

6.1. Three wire connection

Three wire mode differs between fail safe and fail secure configurations but both require a switched power supply

connected to terminals ‘1’ and ‘3’. Wire links (not supplied) are connected from terminals ‘2’ to ‘11’ and ‘1’ to ‘9’ for

fail safe. Additionally, manual override of the lockis achieved by utilising the key cylinder, electrically forfail safe and

mechanically for fail secure.

Fail Safe Fail Secure

6.2. Two wire connection (Fail Secure Only)

A link (not supplied) is connected between

terminals ‘1’ and ‘2’. The YD25K will be locked when

no power is applied and will unlock when power is

applied. The operation remains the same

regardless of door or strike plate position.

Additionally, mechanical manual override of the

lock is achieved by utilising the key cylinder.

6.1. Monitors

The eight monitor connectors found on the YD25K are available to provide door, bolt, and key position feedback. If

desired, wires can be run from these connections to integrate with access control or alarm systems to provide full

monitoring. When a three wire fail safe operation is chosen the key position monitor is not available.
