Thank you for purchasing a Concept Smoke Screen system. Your choice to protect your property and premises with this equipment has given you the use of one of the most effective security systems currently available.

General 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.
1.3 INTRODUCTION This manual covers the Sentinel S55. 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. • Swift-Fit fluid reservoir (boxed).
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 •...
Location 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°.
2.2 INSTALLATION PROCEDURE Site the Smoke Screen and fix to the wall or ceiling as appropriate. 2. Select the “Service Mode” dip switch to “On”. Make connections as required to the alarm panel, hold-off PIR and, if used, the Panic input. Make connection to the Smoke Screen Interface (if used) and set the key switch to isolate.

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...
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.
Function 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’...
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).
Settings 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.
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.
5.8 FLUID MANAGEMENT The Smoke Screen has a replaceable 1 litre Swift-Fit fluid reservoir (also known as product code SFL-1000) that is accessed by removing the cover on the right-hand side of the unit. The fluid level is monitored using sensors in the fluid reservoir to give a “Low Fluid”...
External reservoir A 5000ml external reservoir can be used with Smoke Screen, please contact Concept Smoke Screen if you wish to use this function. 5.9 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.
