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
This unit is intended to simplify the implementation and operation of interlock systems where the
room comprises a divider such that it may be split into two sub-rooms each with its own ICS, or
becomes one larger room when the divider is open, controlled by one of the ICS’s. A typical layout is
shown on the next page.
This version of the unit is compatible with Lasermet’s ICS-6 Interlock Controllers and cannot be used
with ICS-5.
In this manual it is assumed that when the divider is closed the room is divided into two areas
labelled herein as ‘A’ and ‘B’, each of which has its own interlock system which operates
independently of the other. In this manual the system is said to be in ‘two-room mode’ when the
divider is closed. On the front panel of the switch unit, area A is referred to as ‘Area 1’, and area B as
‘Area 2’, to avoid confusion with the two safety input channels which are also labelled ‘A’ and ‘B’.
When the divider is open the ‘A’ area ICS takes control of the whole room and the ‘B’ area ICS is
disabled. This is said to be ‘one-room mode’.
The switching unit is versatile and can be wired such that the signs, overrides and controlled devices
such as lasers and shutters in the B area become controlled by the A ICS when in one-room mode. It
also allows the A area override device to override the B area interlocks and the B area override
device to override the A area interlocks in one-room mode.
The unit provides a duplicate of the B area interlock indications so the status of the B area doors can
be seen on the switching unit even if the B ICS is turned off.
The switching unit is normally set up to operate automatically according to the state of the room
divider, but it can be operated by switches or other means.

3 Installation
The unit is contained within a wall-mountable box. The size and fixing centres are given in the
diagram on the next page.
The box should be fitted to the wall in such a position that the front panel indications can be seen
within the ‘B’ area when the room divider is closed, and from both areas when the divider is open.
The box should be mounted with the long sides horizontal normally cable entries will be at the top
or bottom and this makes the longer sides available for this purpose.
A large number of low voltage cables will need to be taken to the unit. The unit can accept cable
entries on all four sides and consideration should be given to cable routing and entry when
positioning the unit. The unit is powered from low voltage supplies from the two ICSs and no mains
supply is needed.

4 Wiring
This section gives an overview of the general wiring principles as a guide to cable routing. More
detailed information for each function is given in succeeding sections.
When wiring such a system the general principle is to wire all the B area input equipment (door
contacts, override switches, keypads etc.) to the switching unit instead of the B ICS.
The B ICS interlock operators may be wired directly to their controlled devices (shutters, lasers,
maglocks) if they are only to work in two-room mode. Any outputs which have to work in both
modes must be cabled through the switching unit so that they can be controlled by the A ICS in one-
room mode. Note that the switching unit has three contacts which are closed in each mode and the
system should be designed with this limitation in mind. The A ICS must have sufficient spare
interlock operators to do this and a 9-way interlock board is a likely requirement for the A ICS in this
instance.
The signs in both areas are controlled by terminals inside the switching unit, not by the ICS’s. If the
signs are 24VDC powered, then they can be run off the switching unit 24V out terminals so that they
all work in both modes. If the loading is too great for the signs to be powered by one of the ICS PSU’s
then a separate power supply may be used. Mains powered signs may also be used, switched
through the terminals in the switching unit.
The switching unit will then have cabling to the A and B ICS’s as shown below. Note that there are 3
cables to the A ICS and 8 cables to the B ICS. An additional 2-core cable is required to run from the B
ICS to the switching unit for every B area interlock operator contact that has to pass through the
switching unit such that it will operate in one-room mode.
It may be more efficient to use two 16-core cables or one 24-core cable for the signal connections
between the B ICS and the switching unit as this will save four or five cables.
The following list suggests stranded cable with 0.2mm2 strands, the number of strands per core is
recommended.
A ICS
24V and 12V Power 3-core 16 or 24 strand
Sign Control 3-core 16 or 24 strand
ICS/Output Monitor 4-core 7 strand
B ICS
Safety Circuits 4X 4-core 7 strand
Estop Circuit 4-core 7 strand
24V and 12V Power 3-core 16 or 24 strand
Sign Control 3-core 16 or 24 strand
ICS/Output Monitor 4-core 7 strand
Interlock Operators If required to operate in one-room mode.

Switching Unit Mode Selector
The mode selector switch may be a single keyswitch with four contacts or an ISMECH 2/2 door
switch fitted. The switch needs to have two contacts which close in one-room mode only, and two
electrically separate contacts which close in two-room mode only.
From selector switch 8-core 7 strand
When the selector switch is in the one-room position the relays in the switching unit are powered
and they change the B area circuits over from the B ICS to the A ICS (one-room mode). When the
switch is set in the two-room position closed each ICS is responsible for its own area.
4.1 Switching Unit Power Source
The switching unit takes power from either or both ICS’s. A power-commoning arrangement in the
switching unit can be used to provide 24V and 12V power to signs, keypads and shutters provided at
least one ICS is turned on.
The ground / 0V connections of the ICS’s are joined together.
Connect the power supplies from the two ICS’s to the Switch Unit as shown below. Make sure to use
cable of sufficient cross section to carry the expected total load of equipment that may be powered
by the Switch Unit. It is suggested that a minimum of 16/0.2mm cores are used. This may need to be
increased if there is a lot of equipment such as maglocks or low voltage signs to be powered or if the
cable run is long.
For the following circuits multicore cable using 7/0.2mm conductors is usually sufficient.

4.2 Control
The switching unit is controlled by four contacts, two of which must only be closed in one-room
mode (divider or interconnecting door open) and the other two must only close in two-room mode
(divider/interconnecting door closed).
The two contacts which close in one-room mode are wired to J31 pins 1 and 2, and J31 pins 3 and 4.
The two contacts which close in two-room mode are wired to J34 pins 1 and 2, and J34 pins 3 and 4.

4.3 Safety Circuits
The A area door contacts and emergency stop buttons are wired as usual to the A ICS. Refer to the
ICS-6 manual.
The B area door contacts and emergency stop buttons are not wired to the B ICS. Instead they are
connected to ‘B Area’ terminals in the Switch Unit, terminals J11, 12, 13, 15, 16, 28. They are
connected in exactly the same as they would be if they were inside the ICS. Each switch must have
two contacts which close when the door is closed, or the emergency stop button is not pressed. One
contact is wired across the outer two terminals, and the other contact across the middle two
terminals. Refer to the ICS-6 manual for more information and diagrams.
Any unused terminal blocks in J11, 12, 13, 15, 16 must have a jumper fitted between the outer two
terminals, and another jumper fitted between the middle two terminals in the same way as they
would in an ICS-6.

4.4 Override
Doors in the B area may be overridden by connecting external controls to the Switch Unit. The
override facility inside the B area ICS is not used at all.
The switching unit is equipped with an override buzzer and light to indicate when the B area is
overridden. The buzzer may be disabled by removing link LK1 ‘Buzzer Ctrl’ on the main PCB inside
the Switch Unit.
In general, doors in the A area are overridden by connecting the A area override device to the A ICS
in the usual way according to the ICS manual. More information is given below.
There are a number of ways of arranging for the B area interlocks to be overridden, as follows:
ICS-KP12 Keypad
An ICS-KP12 keypad may be provided at one or more entry points into the B area. If this is done the
keypad should be wired to J28 B Area Keypad inside the Switch Unit. Each keypad terminal should be
wired to the terminal with the same name in the Switch Unit. Link LK2 must be fitted on the main
PCB inside the Switch Unit. If there is more than one keypad they should all be wired in parallel to
the same terminals. Keypads must not be wired to the ICS.
If there is a keypad in the A area it is connected as normal to the Keypad terminal block in the A area
ICS as shown in the ICS manual. If it is necessary for it to allow entry through doors in the B area in
one-room mode the four connections from the A area keypad should be taken to both the A ICS and
the A area keypad terminal block J36 in the Switch Unit, as shown on the next page.
