Is the fog emitted harmful?
NO. It is not real smoke - it is a glycol vapour and is harmless.  We have a report, along with a health and safety datasheet, which analyses this in great detail and copies are available. A similar substance is also used in theatres, discos and e-cigarettes.
How do I turn on / arm my SmokeCloak?
SmokeCloak is connected permanently to the mains supply and is triggered by the alarm system. Arming and disarming are therefore controlled by the alarm system.
For how long does the fog pump out? 
The SmokeCloak can activate on initial trigger for between 6 to 59 seconds. If the density of the vapour were to subsequently drop, the CloakSensor (a vapour monitor) will automatically reactivate, maintaining protection. 45 minutes is the typical time the fog will remain if the room is unventilated and at a normal temperature.
How do you recommend the fog is extracted?
After turning off the alarm system, doors and windows can be opened to create a through-draught. The fog should always be evacuated after activation.
Will the fog damage clothing / personal computers / money etc.?
NO. Provided it is installed and maintained correctly, it will not cause any damage.
What happens if the alarm system is accidentally triggered?
SmokeCloak will only operate when the alarm system instructs it to do so. However, when the alarm system is un-set (i.e. during the day) several internal circuits prevent SmokeCloak operating on its own - even if the alarm system malfunctions.  
How many times can SmokeCloak operate on one container of fluid?
It takes 0.45cc of fluid to make 1m3 of vapour. The amount of activations will therefore depend on the machine, the room size and the fluid bottle being used. A SmokeCloak can therefore activate a number of times on a single bottle of fluid. A sensor in the fluid bottle will tell the alarm control panel if it is ‘low fluid’ or, if it is out of fluid, ‘no fluid’.
Will SmokeCloak operate in the event of a mains failure?
Yes - battery back-up is standard on our machines. The control circuits and pumps (in the event of activation) are backed up, but not the main heater. If the mains power is cut, the temperature of the heater block assembly slowly drops and so the maximum smoke production capability reduces, but the system will still provide protection for at least 30 minutes.
What happens if a SmokeCloak cannot operate?
SmokeCloak has a comprehensive communications interface that reports any problems directly to the alarm panel. The key holder will be notified of any problems via a local alarm and visual message facility on the panel. Examples are: reservoir status, block temperature and mains failure.
Does the installation of SmokeCloak affect insurance cover?
Some major insurance companies are offering discounts for the inclusion of SmokeCloak in risk improvement measures.
How does SmokeCloak affect third-party liability?
MSS Professional has arranged an insurance policy to provide public liability cover in the event of a bodily injury arising from the effects of SmokeCloak. This cover is provided free to all SmokeCloak machines, provided they have been installed and maintained in line with the manufacturer’s instructions.
