Automist Personal Protection System (PPS)

Automist® Personal Protection System (PPS) is an independently tested plug and play portable fire sprinkler. It makes it easy for responsible persons to take appropriate fire safety measures without incurring unreasonable cost or disruption and facilitate independent living for those most at risk. It can also be used to protect archives, means of escape, portacabins and critical assets.

The mobile watermist system (MWS) was designed in consultation with the Dorset Fire Service and is fast-acting, highly effective, portable, easy-to-maintain, and unobtrusive. The system can even be leased with payments to suit your budgetary needs.

Installation is as simple as linking to a double knock smoke alarm or a flame detector with audible warning for early activation, and plugging into a nearby socket. Automist PPS is unique because it can be customised to meet a variety of risk profiles, and can be hidden within any home as it is designed to look like a standard radiator.

The unit is connected to a GSM module so will notify you by text message when it has been activated, or the power has been disconnected and the system has reverted to battery backup. The PPS also integrates with NFC Groups Orion Data Network which, being SIM free technology, increases reliability and a further layer of redundancy. Units deployed by the Dorset Fire & Rescue Service are connected in this way, a first for this kind of product.

Automist local application watermist system

The system fulfils a need to protect vulnerable people and prevent unnecessary deaths and injury. It works quickly and efficiently, and the link-up to the Orion Data Network provides added peace of mind.

A typical application would be to protect a vulnerable person who spends the majority of their time in either a bed or chair and because of mental and/or physical health issues is more prone to starting fires accidentally and/or unable to escape quickly. The fire hazard can, therefore, be considered to be localised to a specific area within the home.

Key: Flame detection means the system can be installed in the home of a heavy smoker and the system will only activate if a naked flame is present in the protected area for a sustained period

Automist PPS looks to detect and suppress the fire at an early stage before significant heat and smoke has developed and therefore before a serious injury can occur. It can only be deactivated with a key switch. It is recommended that it is deployed as part of a package of measures designed to reduce the fire risk to a vulnerable person.


Detection Options


Flame detection with audible warning

The Flame Detector is designed to detect a 25 mm (1 inch) flame at a distance of 6 metres (7 yards) within 1 second and provides voice messages in any language. Before the system activates it will alert, "extinguish the flame or the system will activate in 10, 9, 8...". The detector can be purchased in a wired or wireless version.

Double knock smoke alarms

Two optical smoke alarms positioned a short distance apart must both activate for 10 seconds simultaneously in order to activate the system.

Care must be taken to ensure that the risk profile is appropriate. The risk assessment needs to indicate the principal fire hazard is within the discharge area, of one or more PPS. If the fire hazard is not localised then a fixed system that covers the whole of the dwelling or risk area should be specified.
