1 Safety Warnings
This device is intended to be used as part of a safety system which may be used to protect personnel
and equipment from possible injury, damage, or loss.
As such it must be installed and wired according to these instructions and tested by suitably qualified
persons. No attempt may be made to tamper with the parts, open them, or use them outside of the
parameters contained herein.
The units are only designed to be fixed to surfaces using their inbuilt fixing holes. They must not come
into contact with each other or any other moving part when in use. The parts should never be subject
to impact or mechanical strain.
Safety switches should never be defeated or bypassed. It is imperative that all steps are taken to
ensure that any spare actuators are made unavailable, such that they cannot be used to defeat the
switch or reduce the protection offered by the system in any way.

2 Concept
The ICS-KP12 Keypad is intended to be used in conjunction with Lasermet’s Laser Interlock systems
for the purpose of inhibiting access to a hazardous area to unauthorised persons. Normally this means
persons without the necessary training and personal protective equipment for the area concerned.
The keypad is sited outside a door which is electrically locked and monitored by the interlock system.
The keypad is not intended to be used as part of a security system.
The keypad has two outputs which may be programmed to activate for a defined time interval when
the correct 4-digit user code is entered. When wired into a Lasermet interlock system, one output is
used to unlock the door and one to activate the override function within the interlock control system
to allow the door to be opened without tripping out the laser.
It is possible to disable either of the outputs. This may be used for example where the door is
monitored by the interlock system but is not fitted with an electric lock, in which case the door lock
function would be disabled.
The override timer function has a fixed hardware backup with contact monitoring so that should the
programmed time function fail the override will still cease after around 30-45 seconds, restoring the
full protection of the interlock system.
Lasermet provides a full range of laser interlock equipment including control systems, interlock
switches, illuminated warning signs, laser shutters, door locks, external power supplies etc. which can
be connected to provide a complete laser interlock system. Full support, design and installation is
available from Lasermet, please contact us for any queries. Contact details are given at the end of this
manual.
2.1 Configuration Options
The ICS-KP12 Keypad has two outputs which activate for a set time when the correct 4-digit user code
is entered: the Override output and the Door Unlock output. Each output illuminates a corresponding
indication on the keypad when activated.
Each output may be independently programmed to activate for a set time between 1 and 30 seconds
when the correct code is entered on the keypad. An output is disabled by programming it to operate
for 0 seconds.
For laser interlock systems in which the entry door is electrically locked, e.g. by a maglock, the Door
Unlock output should be used to release the door, and the Door Unlock time should be programmed
for the required door lock release time.
If there is no electric lock on the door, the Door Unlock output is not used and the Door Unlock time
should be set to 0 to disable the indication on the keypad.

ICS-KP12 Instruction Manual
00517-53-000 Page 5 of 17 Issue 3 15 January 2020
The entry door will normally be fitted with an interlock switch that indicates to the interlock control
system that the door has been opened and this will cause the laser to be disabled. The Override output
should be used when it is desired to be able to open the entry door without disabling the laser. The
Override time should be set to the shortest reasonable time required for the door to be opened and
then closed again.
If it is desired to be able to release the door lock only i.e. the laser will be disabled when the door
opens, the Override output can be disabled by setting the time duration to 0.
The ICS-KP12 has a remote activation input which may be wired to an external pushbutton switch.
This is usually provided on the inside of the controlled door and allows persons to leave the controlled
area without disabling the laser. When the button is pressed, the keypad performs the same functions
as if the user code had been entered.
3 Installation
The ICS-KP12 is designed to be permanently attached to a wall or other fixed vertical surface.
3.1 Positioning
The ICS-KP12 should be mounted in a convenient position for use and wiring. Normally it is located on
the outside (‘safe’) side of the entry door of the controlled area, on the wall adjacent to the door
handle, approximately 1.2m up from floor level.
During installation, wired connections will need to be made from the ICS-KP12 to the Interlock Control
System and possibly the magnetic door lock, and allowance should be made for the installation of
electrical conduit or trunking if required to make entry to the unit.
Ideally the keypad should be attached directly to the wall with the cables being fed from within the
wall. For hollow walls this should be straightforward. For solid walls it may be easiest and neatest to
feed the cables right through the wall from the other side.
Alternatively, the keypad may be attached to a round conduit box which may be buried or surface-
mounted, though this last option will result in the unit projecting further from the wall, making it less
stable and more vulnerable.
It is recommended that the centre of mounting is at least 100mm horizontally from the door
surround/architrave and at least 150mm from the edge of the door. There must be a flat unobstructed
area of wall extending at least 70mm above and 110mm below the mounting centre to allow fitment
and removal.
If a Lasermet Miniature Warning Sign is being fitted above the keypad the centres should be at least
140mm apart vertically.

Refer to Figure 1 for details of the fixing holes and cable entry. The wall plate and locking plate are
secured using preferably four screws on a 35.4mm square around the cable entry point. The locking
plate and plastic wall plate disk are pre-drilled and may be used as a marking template. If using a round
conduit box, the holes will align with the cover fixing holes.
Once all the holes have been made, secure the wall plate and the locking plate as shown in Figure 1
with the plastic wall plate against the wall. Check that the plastic wall plate and locking plate are
aligned as shown.
Feed the cables through the hole in the centre of the locking plate.
NOTE: Make the electrical connections before attaching the unit to the wall plate, see the Wiring
section.

4 Wiring
The keypad is powered by 24VDC. A four-way plug-in terminal block is provided for the control and
power connections, and it is usually easiest to unplug the terminals while making the connections. The
connections are shown in Figure 2.
Figure 2. Terminal Identification
The power supply is connected with the positive to the +24V terminal and the negative to the 0V
terminal.
The REM input can be connected to a separate pushbutton switch to activate the keypad remotely.
When the button is pressed, the keypad activates its outputs according to the programmed settings
as though the correct code had been entered on the keypad. The pushbutton is wired between the
REM and +24V terminals. If this function is not required, simply make no connection to the REM
terminal.
The O/R terminal is the override output. The keypad connects this terminal to +24V while the override
is active. This is wired to the override input in the ICS panel.

4.1 Connecting to Lasermet ICS Control Panels
Connecting to ICS-6
Refer to Figure 3.
ICS-6 is equipped with a set of terminals for direct connection to the ICS-KP12. Wire the four terminals
labelled +24V, REM, O/R, 0V inside the ICS-6 directly to the corresponding terminals of J17 inside the
keypad using four-core low-voltage cable such as burglar alarm cable.
If an internal door release pushbutton is required, it may be connected across the +24V and REM
terminals in addition to the four-core cable at either end i.e. inside the keypad or inside the ICS-6,
according to installation preference.
Ensure the plug-in jumper link J2 ‘O/RIDE CTRL’ on the ICS-6 Main Circuit Board is set closed (both pins
shorted together) so that the keypad can activate the override circuitry inside the ICS-6.
Once the wiring connections have been made, attach the keypad to the wall plate as described later
in this manual.
4.2 Connecting to Door Lock
The ICS-KP12 has a relay for releasing electric door locks. The relay is rated at 6A resistive load. This is
normally sufficient for two magnetic door locks. Note that magnetic door locks must be fitted with
suppression diodes and must be connected the right way round. Magnetic door locks supplied by
Lasermet have the diode built in.
The contacts are available on the terminals labelled COM, NO, NC on terminal block J4 inside the
keypad. This terminal block is fixed to the circuit board and does not unplug.
The positive feed to the door lock should be connected to the COM terminal inside the keypad, and
the NC terminal should then go to the positive connection of the lock, see figure 4. This will enable the
keypad to break the circuit to the lock thus releasing it.
Refer to the ICS Manual for more information on wiring door locks to the system.
If no lock is provided this part of the circuit may be omitted, and the keypad may be programmed not
to activate the door relay and ‘Door Unlocked’ indication.

4.3 Connecting two or more Keypads to one ICS
If it is desired to be able to access the controlled area through more than one door while the laser is
on, additional keypads may be connected as required.
In this case, to prevent all the doors being released at once when an exit button is pressed, the REM
connection from each keypad is not wired back to the ICS, but just wired to the exit button for the
relevant door.
