1.1 SAFETY INSTRUCTIONS
Before installing and using the Smoke Screen read, follow and retain this manual and safety instructions for future
reference.
To reduce the risk of severe injury or death to persons, or damage to the Smoke Screen:
• Do not work on the Smoke Screen unless qualified by the manufacturer to do so.
• Disconnect the mains power supply before working in the heater block compartment or anywhere that
mains voltage is indicated by the warning labels shown below (this is engraved with the layout of the
PCB connections).
• Install in accordance with the instructions in this manual.
• Operate the Smoke Screen only from the type of power source indicated on the label.
• Do not modify the Smoke Screen.
• Adjust only the controls specified in this manual.
• Use only consumables and replacement parts specified by the manufacturer.
• Do not spill liquid of any type on, or inside, the Smoke Screen.
The following signs, or a variation, may be used for safety notices in this manual or on the Smoke Screen:
This type of warning note is used
to indicate possible electrical
shock hazards that may cause
serious injuries or death.
This type of warning note is used
to indicate the possibility of injury
caused by hazards other than
electrical shock.
1.2 HOW DOES YOUR SMOKE SCREEN WORK?
Your Smoke Screen passes a non-toxic fluid through an efficient heat exchanger to create smoke, or more
accurately a thermally generated fog that obscures visibility, discouraging intruders from entering your premises.
This fog is very persistent and will stay suspended in the room for a significant length of time until it is vented by
opening the doors and windows.
The Smoke Screen uses a sophisticated electronic control system to ensure it heats up to, and maintains, its ideal
operating temperature using a minimal amount of electricity.
The control system similarly provides a flexible interface with intruder detectors, alarm systems and remote
monitoring centres to ensure that you are always protected and free of inadvertent activations.

1.3 INTRODUCTION
This manual covers the Sentinel S35.
Before commencing installation of the Smoke Screen ensure that you have all the following equipment supplied
in the box:
• 1 x Smoke Screen.
• 1 x Mounting bracket.
• 1 x Smoke fluid consumable.
• 2 x 12v batteries.
• 1 x Literature pack and warning sign.
• 1 x Extra 30-degree Nozzle for wall mounted installation.
You will also need:
• Mains power supply; an unswitched 13 amp fused spur connected to a dedicated breaker.
• Connections into the alarm panel or other triggering system.
• PIR (or equivalent) to provide the hold-off where required.
1.4 OVERVIEW
The Smoke Screen is designed to form part of an existing intruder alarm system but may also be configured as a
‘stand-alone’ system or as part of a centrally monitored, command and control system. A typical installation is
shown in the following schematic:

5
1.5 TYPICAL INSTALLATIONS
A typical installation can be configured in the following way:
• The Smoke Screen is wall or ceiling mounted in the appropriate location.
• A Hold-off PIR (or similar device) located within the same area as the Smoke Screen providing a
confirmation signal to the Smoke Screen to start, or restart, ‘smoke’ production.
• A Set command supplied by an alarm control panel, or equivalent, in the form of an N/C (normally
closed) or an N/O (normally open) relay changing state when the alarm system is set for operation.
• An Alarm command supplied by the alarm control panel, or equivalent, in the form of an N/C (normally
closed) or an N/O (normally open) relay changing state when the alarm system confirms an intruder
alert.
• A Panic command in the form of an N/C (normally closed) or an N/O (normally open) switch, or
equivalent clean contact, that is opened or closed when an instant activation is required.

6
Location 2
2.1 POSITIONING
The Smoke Screen should ideally be sited in a covert position away from prying eyes and thereby reducing the
possibility of tamper or an attack. The ideal place for the Smoke Screen is above a ceiling from where the smoke
plume is used to its best effect, bursting on the ground and spreading outwards and upwards through 360°. If no
suitable ceiling location is available then the next best location is a wall mounting as close to ceiling height as
possible.
Wall-mounting
The optimum wall mounting position for the Smoke Screen is 2.5 metres above the floor facing the area to be
protected and using the 30-degree angle nozzle. The maximum recommended mounting-height above floor
level is 3 metres, the minimum is 1 metre and there should be no obstacle within 1 metre of the smoke output
nozzle. Also, leave a minimum of 150mm clearance to the ceiling.
Ceiling-mounting
The optimum ceiling mounting position for the Smoke Screen is 2.5 metres above the floor facing the area to be
protected and using the standard straight nozzle. The maximum recommended mounting-height above floor level
is 3 metres, the minimum is 1 metre and there should be no obstacle within 1 metre of the smoke output nozzle.

7
2.2 INSTALLATION PROCEDURE
1. Site the Smoke Screen and fix to the wall or ceiling as appropriate.
2. Select the “Service Mode” dip switch to “On”.
3. Make connections as required to the alarm panel, hold-off PIR and, if used, the Panic input.
4. Make connection to the Smoke Screen Interface (if used) and set the key switch to isolate.
5. Turn on the internal battery back-up.
6. With the battery power applied insert fluid consumable and make sure the fluid switch is closed correctly.
7. Connect and turn on the mains power.
8. The Smoke Screen will heat up to operating temperature in approximately 20 minutes.
9. Set correct time/date and smoke timing for the specified room size.
10. Ensure the “Service Mode” dip switch is selected to “Off”.
11. Make sure all tamper switches are closed.
12. If fitted set the Smoke Screen Interface key switch to ‘Ready’ and you are ready for test.
2.3 ACCESS
To access the PCB connections, programming panel, mounting holes, batteries and fluid, remove the front cover
by unscrewing the set screws on either side and unhooking it from the back plate; refitting is the reverse process.
Installation cable entry is through the serrated grommet on the left side of the back plate.
2.4 MOUNTING
The Smoke Screen can be mounted on a ceiling or a wall using the simple standard bracket supplied with the
unit. This flush-fitting bracket maximizes security by concealing all the mounting fastenings such that they can
only be accessed, or the Smoke Screen dismounted, by dismantling the unit. Moreover, the Smoke Screen has a
tamper protection switch to provide an alert in the unlikely event that it is disturbed. In all cases, the installer must
attach the Smoke Screen to the building structure using appropriate fasteners.
NB: When mounting the Smoke Screen ensure that the airflow through the vent holes in the rear of the unit is not
obstructed.
Wall and ceiling mounting
Ceiling or wall mounting is the same process except that rather than fixing the Smoke Screen direct to a ceiling
an intermediate unistrut section may be used or it can be suspended as described in the next section.
Attach the bracket to the wall or ceiling using
appropriate fixings.
Carefully hook the slots on the back of the
Smoke Screen onto the bracket (for clarity,
shown above not attached to the ceiling/wall).
Slide along to align the screw fixing holes.
The unit will now hang on the bracket.
Fit, and ensure tight, 1x M6 set screw with
washer in the hole in the back of the Smoke
Screen alongside each of the two mounting
slots. Access to the fixing holes is through the
fluid and heater block compartments.

Suspension mounting
Suspending the Smoke Screen is achieved using a ‘Suspension Kit’ comprising a length of unistrut, two sections
of threaded bar and fixings.
Suspension Kit Contents (all M8)
Unistrut 1 x 1 metre
Threaded bar 2 x 1 metre
Fixings:
1 x ceiling hole surround
2 x drop-in anchors
6 x full nuts
4 x 25mm washers
2 x 38mm washers
2 x channel nuts
Prepare the Smoke Screen by fitting the angle
brackets. Fix the required length of M8 threaded
bar to the bracket using 4 x nuts and 4 x 25mm
washers.
Fix the unistrut into place. There are a range of
fixings to accommodate concrete ceiling,
girders etc.; if in doubt contact the fixing
supplier. Attach the threaded bar to the unistrut
using the channel nuts, 38mm washers and M8
nuts. Once this is done the Smoke Screen can
be lifted into position and the set screws
tightened as above.
Any fine adjustments can be made at this stage
as the nuts and the threaded bar will take the
weight of the Smoke Screen.
The final assembly, viewed ‘through the ceiling’
is in the photo. Any hole made in the ceiling
below can be made good with a cosmetic hole
surround.
2.5 NOZZLE CHANGING
To change the nozzle, first remove the front cover then remove and replace the nozzle using a 10mm ring
spanner, sealing it with PTFE tape and ensuring that an angled nozzle is seated in the correct orientation. The
Smoke Screen is delivered with a single-hole straight nozzle plus an extra 1-hole 30 deg angle down nozzle. The
following are also available – 2-hole horizontal, 3-hole horizontal, 1-hole 30° angle down and 2-hole 30° angle
down.
Be aware of high voltage in the block
area. The electrical supply should be
switched off before working in the
heater block compartment.
This operation is usually carried out
during installation. If the Smoke Screen
has been in service the nozzles will be
extremely hot and will cause injury if
touched. Therefore, the Smoke Screen
should be switched off and time should
be allowed for the nozzles to cool.

Function 3
3.1 CONTROLLING THE SMOKE
Alarm Panel activation
There are 3 sets of input connections on the Smoke Screen (Set, Alarm and Hold-off) that should be connected to
clean contacts. For the Smoke Screen to produce ‘smoke’ all 3 sets of connections must be ‘open circuit’ (this can
be changed to ‘closed = activate’ – see the “Inverting Trigger Mode” Section but note that ‘open = activate’ is
used in this manual). We recommend using the default setting ‘open circuit = activation’ to ensure that the Smoke
Screen will activate in case the alarm cables are tampered from the outside. If one set of connections is ‘closed
circuit’ then the Smoke Screen is prevented from producing smoke. Hence the production of smoke is controlled
using one or a combination of the following:
• Set – a normally closed relay connected across the alarm panel ‘Set’ output connections, which is
open when the alarm panel is ‘Set’ and closed when the panel is ‘Unset’.
• Alarm – a normally closed relay connected across the alarm panel ‘Intruder’ output connections, which
is open when the alarm panel or controlling device is in ‘Alarm’.
• Hold-off – usually a PIR / movement sensor normally closed output, which opens when the sensor
detects movement, connected to the Smoke Screen “Hold-off” normally closed connections.
• Additional hold-off – any form of normally closed relay / micro switch can be connected to the “Hold-
off” connections. Where fitted in parallel as an addition to a PIR both devices must be ‘open’ to
produce ‘smoke’.
Panic activation
The Smoke Screen has a Panic input that should be connected to a clean contact going ‘open circuit’ to activate
(this can be changed to ‘closed = activate’ – see “Invert Trigger Mode” in the Programming section).
It is recommended that the Panic is activated by a momentary, non-latching, button to avoid the situation where a
Panic activation is not reset before a standard activation is required.
NB: The Panic trigger mode is delivered set to n/o and the Panic Smoke Time is set to 0 seconds to prevent
inadvertent activation if the facility is not used.
WARNINGS:
•
Service Mode should be selected to on if the Panic trigger mode is changed when the Smoke
Screen is at operating temperature.
•
Always restore a Panic input after it has been used. Failure to do so will result in the Smoke Screen
not subsequently activating on an Alarm Panel (Set, Alarm and Hold-off) demand.
Smoke and Panic Time
The Smoke Screen should be set to produce fog for a time (Smoke Time) that is suitable for the volume of the
location to be protected. As a guide, an S55 set to 60 seconds Smoke Time will reduce the visibility to 1 metre*
in a 175 m3volume room. The Smoke Time is changed in the settings; see Section 5.9.
(* as defined by the test requirements of EN50131-8)

10
Hold-off settling time
A “Settle Timer” can be programmed for a period between 0 and 60 seconds (in 1 second intervals) during which
the Smoke Screen will not react to a hold-off input after receiving a ‘Set’ command.
Delaying an activation
After the Smoke Screen has received the required 3 inputs to produce smoke, an activation can be delayed for a
period between 0 and 60 seconds (in 1 second intervals). This can be used to sequence activations in a multi-
machine installation. See “Smoke Delay” in the Programming section.
NB:
The Delay Timer and Settle Timer are cumulative, ie if a Delay Time of 5 seconds and a Settle Timer of 30
seconds are set the Smoke Screen will not activate for 35 seconds after it receives a “Set” input.
Re-triggering
If a Smoke Delay time has been set the menu gives the option to select the following options for subsequent re-
triggers initiated by a hold-off if the Set and Alarm remain in alarm:
•
Delay:
Repeat activations are delayed by the Delay Time set.
•
Instant:
Repeat activations are instantaneous.
Stopping an activation
Once activated the Smoke Screen will stop producing ‘smoke’ before the end of the programmed smoke time
only if the ‘Set’ is restored to a non-alarm state.
A Panic activation can be stopped before the end of the programmed smoke time only if the ‘Set’ is cycled to
alarm and back to restore.
Preventing an activation
To prevent the Smoke Screen from making smoke during a service inspection under any circumstances select
the “Service Mode” dip switch to on (see separate section).
3.2 OUTPUTS
Clean contact outputs are provided for connection to the alarm panel for ‘Mains Fail’, ‘Temp Status’, ‘Empty Fluid’,
‘Battery Output’, ‘Tamper’, ‘Verification Output’ and ‘Low Fluid’. See the notes on the “Generic Connection
Diagram” for the function of these outputs.

Settings 5
5.1 SCREEN SENSOR
A Concept Smoke Screen “Screen Sensor” can be connected to the Sentinel. When this is integrated the system
detects a drop in the fog density in the protected area and will re-trigger the Sentinel to maintain the fog level.
When fitted the Screen Sensor is connected to the Hold Off input pins and, consequently, it prevents the use of a
hold-off detector.
NB: It is critical that the Screen Sensor is installed in an area that receives the maximum fog coverage. It will
not operate correctly if this is not achieved
5.2 ENERGY SAVING MODE (ESM)
The Smoke Screen has 3 options for ESM:
•
ESM Disable.
The Smoke Screen maintains its normal running temperature.
•
ESM.
When ESM is selected and the alarm panel input to the Smoke Screen is “Unset” the Smoke
Screen lowers its running temperature to a standby level to reduce power consumption and cost. When
the Smoke Screen receives an ‘Alarm Set’ input it automatically heats to its normal operating
temperature.
NB:
If the Smoke Screen is in ESM mode and is activated as soon as the alarm is set, ie before it has
heated to normal operating temperature, it will still produce smoke but the length of time of the initial
burst of fog will be shortened.
•
Extreme.
When Extreme is selected and the alarm panel input to the Smoke Screen is “Unset” the
Smoke Screen heater is not operated, and its temperature reduces to ambient. When the Smoke Screen
receives a ‘Set’ input it automatically heats to its normal operating temperature.
NB
: This will introduce a period where the Smoke Screen cannot produce fog as it heats up.
WARNING: ESM and Extreme should not be used if the Smoke Screen is being used with a Panic input.
5.3 VERIFICATION TIMER
If the “Verify Timer” is set to 0 seconds the verification output changes state during an activation for the set
“Smoke Time”. If the “Verify Timer” is set above the set Smoke Time the verification output maintains the
changed state for that time after an activation starts.
NB: The Live Status verification display (V) is shown only during the production of fog, not for any subsequent
time set by the “Verify Timer”.

14
5.4 SERVICE MODE
Setting dip switch No 4 (see diagram under “Circuit Board Layout”) to “On” puts the Smoke Screen into “Service
Mode”. This setting prevents the Smoke Screen from making smoke whilst work is conducted with power applied.
To highlight that the Smoke Screen is in “Service Mode” the Tamper output is put into an alarm state.
FAILURE TO DISABLE SERVICE MODE WHEN NO LONGER REQUIRED WILL PREVENT THE SMOKE SCREEN
OPERATING.
5.5 INVERTING TRIGGERS
The Smoke Screen triggers, Set, Alarm, Hold-off and Panic should be connected to clean contacts changing state
in alarm. The triggers can be set to ‘open = activate’ or ‘closed = activate’. We recommend using the default
setting ‘open circuit (n/c in menu) = activation’ to ensure that the Smoke Screen will activate in case the alarm
cables are tampered from the outside.
The Smoke Screen is delivered with the Set, Alarm and Hold-off triggers set to n/c, ie ‘open = activate’. The Panic
trigger is set to n/o to avoid an inadvertent activation if the facility is not used and the Panic input is left open.
5.6 TAMPER
There are internal tamper circuits on all the Smoke Screen covers and an external tamper input on PCB terminal
block “B”. A “Tamper Status” output is provided on PCB terminal block “F”. To prevent unwanted tamper signals
the external tamper input can be disabled if not in use by selecting dip switch 2 to “On”, which bridges the input
pins on the PCB.
NB:
A tamper ‘open’ state provides only an indication of the event; it does not automatically activate the Smoke
Screen or prevent it from activation.
5.7 REBOOT
The Smoke Screen can be rebooted without removing mains and battery power by selecting “Yes” in the Reboot
menu item that is available when the Smoke Screen is in Service Mode. Any settings entered in the menu will be
retained. This facility can be used to clear any critical faults.
5.8 FLUID MANAGEMENT
The S35 accommodates a 500ml consumable containing ‘Smoke Fluid’. The Fluid Level is monitored using an
on-board timer that measures the amount of fluid used by timing consumption when the Smoke Screen is
activated. Each time the consumable clamp is unfastened, and the fluid consumable is replaced the micro switch
is cycled which resets the internal timer that the Smoke Screen use to calculate the volume of fluid remaining in
the fluid bag. See the section on “Programming” to set the volume of fluid available a new fluid consumable. The
Smoke Screen will not produce fog when there is an “Empty Fluid” indication

15
Be aware of high voltage in the
Smoke Screen. The mains
electrical supply should be
switched off before changing
the fluid consumable.
If the generator has been in
service the heater block and
connected parts will be
extremely hot and will cause
injury if touched. Switch off and
allow the heater block to cool.
Changing a fluid consumable
Obtain a replacement fluid consumable from your Smoke Screen supplier. Ensure that power is applied to the
Smoke Screen (this should be only battery power) and remove the Smoke Screen cover.

16
WARNINGS:
WHEN A NEW FLUID CONSUMABLE IS FITTED BATTERY POWER MUST BE APPLIED TO THE SMOKE
SCREEN TO RESET THE FLUID TIMER.
ALWAYS REPLACE A FULL FLUID CONSUMABLE EVERY TIME THE FLUID CONSUMABLE HOLDER MICRO
SWITCH IS RESET. FAILURE TO DO SO MAY RESULT IN DAMAGE TO THE FLUID PUMP.
THE SMOKE SCREEN WILL NOT PRODUCE FOG IF THE CONSUMABLE NECK IS NOT CORRECTLY FITTED
TO THE HOLDER AND THE MICRO SWITCH IS NOT CLOSED.
External reservoir
A 5000ml external reservoir can be used with Smoke Screen, please contact Concept Smoke Screen if you wish
to use this function.

17
5.8 BATTERY MANAGEMENT
Operation
The Smoke Screen is fitted with a battery to provide power to the electronic circuits and pump (not to the fluid
heater) in the event of a mains power failure. This ensures that the Smoke Screen can provide an effective
activation for at least 1 hour after a mains power failure (further detail is on the relevant Smoke Screen datasheet).
The Smoke Screen is capable of activating in the event of a battery fault or if the batteries are not fitted; in the
latter case, to avoid battery fault indications, the facility should be disabled (see “Programming”). The Smoke
Screen is supplied with a set of batteries and replacement batteries may be obtained from your Smoke Screen
distributor or Concept Smoke Screen.
Battery protection
To prevent damage to the batteries caused by
running them to a completely discharged state, the
Smoke Screen will switch off the battery power 1.5 hours
after a mains power failure, at which time the unit is too
cold to activate; the Smoke Screen will start up normally
as soon as mains power is re-applied.
Battery switch
The Smoke Screen has a switch on the PCB to permit the batteries to be disconnected from the system whilst
remaining in place (see the picture above). The delivery setting is “Off”; select to “On” if intending to use the
battery facility.
Removal and replacement
Disconnect the mains power supply. Take off the Smoke Screen front cover, the battery compartment cover on
the left side and the mains power cover on the PCB. Disconnect the battery plugs from the PCB. Slide out the
old batteries, replace with new units and refit the plugs and covers
THE SMOKE SCREEN WILL NOT FUNCTION AT ALL DURING A MAINS POWER FAILURE IF THE BATTERIES
ARE DISABLED.
Be aware of high voltage in the
Smoke Screen. The electrical
supply should be switched off
before changing the batteries.
If the generator has been in
service the heater block and
connected parts will be extremely
hot and will cause injury if touched.
Switch off and allow the heater
block to cool.
