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.

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.

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.

NO. Provided it is installed and maintained correctly, it will not cause any damage.

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.
