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.
5
1.3 INTRODUCTION
This manual covers the Sentinel S35.
Before commencing installation of the Smoke Screen ensure that you have all of 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.
You will also need:
●Mains power supply; an un-switched 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:
6
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 re-start, ‘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.
●A Trigger 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.

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 an appropriate 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.
Ceiling-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 an appropriate 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.
8
2.2 INSTALLATION PROCESS
1. Site the Smoke Screen, 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 and hold-off PIR.
4. Make connection to the Smoke Screen Interface (if used) and set the key switch to isolate.
5. Connect and turn on the mains power.
6. Turn on the internal battery back-up.
7. The Smoke Screen will heat up to operating temperature in approximately 20 minutes.
8. Set correct time/date and smoke timing for the specified room size.
9. Ensure the “Service Mode” dip switch is selected to “Off”.
10. With the power applied insert fluid consumable and make sure the fluid switch is closed correctly.
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 2 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 right-hand side of the back plate.
9
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.
Slide along to align the screw fixing
holes. The unit will now hang on the
bracket. Fit, and ensure tight, 4 x M6
set screws with washers in the holes
in the back of the Smoke Screen
alongside each mounting slot.
Access to the fixing holes is through
the fluid and heater block
compartments.
10
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
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 to allow smoke through a
suspended ceiling below the Smoke
Screen can be made good with a
cosmetic hole surround.
11
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 and 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.

3.1 CONTROLLING THE SMOKE
Inputs
There are 3 sets of input connections on the Smoke Screen (Alarm Set, Trigger 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 “Invert Trigger Mode” in the Programming section but note
that ‘open = activate’ is used in this manual). We recommend to use 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:
Alarm 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’.
Trigger – a normally closed relay connected across the alarm panel ‘Trigger’ or ‘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’.
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.
Stopping an activation
Once activated the Smoke Screen will stop producing ‘smoke’ before the end of the programmed smoke time only if
the ‘Alarm Set’ is selected to a non-alarm state.
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).
13
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.
14
Settings
5
5.1 SCREEN SENSOR
A “Screen Sensor” can be connected to the Sentinel as shown in the “Generic Connection Diagram”. 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. (See 4.2 generic connection diagram).
5.2 ENERGY SAVING MODE (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. 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 possibly for a shorter period than the set smoke time.
5.3 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.
5.4 TURBO SMOKE MODE
When “Turbo Smoke Mode” is set (see section under “Programming”) the Smoke Screen produces a high-volume
burst of smoke to provide rapid obscuration of a local, high value protected area. In “Normal Smoke Mode” the
Smoke Screen produces a short full-output burst followed by a lower output over a longer period.
17
5.5 TAMPER
There is an internal tamper circuit on the Smoke Screen cover and an external tamper input on PCB terminal block
“B”. A “Tamper Status” output is provided on PCB terminal block “C”. 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. A tamper ‘open’ state provides only an indication of the event; it does not automatically activate the Smoke
Screen or prevent it from activation.
5.6 FLUID MANAGEMENT
Fluid capacity and monitoring. 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 timer and the Smoke Screen will calculate this as a new fluid consumable.
See the section on “Programming” to set the volume of fluid available to the Smoke Screen.
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.
18
Changing a fluid consumable
Ensure that power is applied to the Smoke Screen; this should only be battery power. Remove the Smoke Screen
cover. Unscrew the consumable holder retaining screw and the consumable support screw. Push the fluid probe into
the “out” position in the consumable neck. Place the other end of the consumable onto the support and insert the
retaining screw. Carefully locate the consumable neck in the cradle (h) and (i). Close the retaining gate and insert the
retaining screw (j). Ensure the consumable neck is held correctly and the fluid micro switch is closed properly.
External reservoir
This facility is designed only for demonstration purposes; please contact Concept Smoke Screen if you wish to use
this function. When a 5 litre external fluid bottle is used and the timer is set to 5,000ml via the LCD control panel the
function of the micro switch on the fluid consumable holder is changed and a consumable should not be fitted. In this
mode, with power applied to the Smoke Screen, momentarily pressing and leaving open the micro switch on the fluid
consumable holder resets the fluid timer to 5,000ml available.
ALWAYS REPLACE A FULL FLUID CONSUMABLE OR 5,000ML BOTTLE EVERY TIME THE FLUID CONSUMABLE
HOLDER MICRO SWITCH IS RESET. FAILURE TO DO SO MAY RESULT IN DAMAGE TO THE SMOKE FLUID PUMP.
WHEN A NEW FLUID CONSUMABLE IS FITTED BATTERY POWER MUST BE APPLIED TO THE SMOKE SCREEN TO
RESET THE FLUID TIMER.
19
5.7 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 20 minutes after a mains power failure at an ambient
temperature of 20°C the Smoke Screen can provide a minimum 40 second activation. The Smoke Screen is capable
of activating solely on mains power 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 but they are not fitted on delivery. Replacement batteries may be obtained from your Smoke
Screen installer 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 above the battery compartment to let the batteries be disconnected from the system
whilst remaining in place. The delivery setting is “Off”; select to “On” if intending to use the battery facility.
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.
