Introduction

What is Airis?

Airis is a 'stove guard'; accredited to BS EN50615:2015. It cuts the power to the cooker and prevents fires without affecting normal cooking. It can also turn off the power when a pan boils dry or food starts to burn.

Airis sensor

The wireless Airis sensor can be fitted to the front or back of the cooker hood or on the wall behind the hob without any additional hardware. It comes with ten different coloured cover options, making it complementary to any kitchen.

Airis-C sensor

The wireless Airis-C sensor is fitted on the ceiling for the most discrete installation and in situations where no suitable mounting place is available for the standard sensor e.g. for an island hob.

The power control unit (PCU)

The PCU controls the power to the cooker and continually analyses the power being used. This data is combined with sensor data to determine when action needs to be taken to prevent a fire, and to turn off the power when a pan boils dry or food starts to burn.

Design & Installation

Aesthetic

The Safera Airis is designed with aesthetics in mind. The sensor has a discrete appearance and comes with a selection of 10 colour options in the box, so it perfectly blends into the décor of the kitchen. Residents will hardly know it's there.

Installation

Airis is the easiest stove guard to install, as in most cases no settings need to be changed. The Airis sensor can be mounted at the front or back of a cooker hood, or on the wall/splashback behind the hob. The Airis-C sensor is mounted on the ceiling.

See the video section (to the right, or below if using a mobile device) for a video showing the installation process. Please note, the 3-phase version of Airis was used in this video. The Airis-C has the same PCU, so the only difference is the ceiling mounting of the sensor.

The power control unit (PCU) can be mounted in any orientation and fitted wherever it best integrates with the kitchen layout. It doesn't have any switches or controls that could be tampered with. For a hob with an oven underneath, it can be fitted directly behind the oven, or underneath the plinth. For a floor-standing cooker, the PCU can be mounted on the wall behind the cooker or another convenient location.

High quality screw terminals and cable restraints are provided for supply and load connections for single or multi-strand cables of up to 10mm2. The supply cable can, if required, be fed through a break-out section at the rear of the PCU as shown in the video. Screw holes allow the PCU to be mounted directly onto the pattress box or the input. Alternatively, both supply and load cables can be fed via adjacent ports at the end of the PCU. Removable blanking plates and grommets are included to allow either configuration.

Once the sensor and PCU are in place and powered up, final setup is literally a matter of seconds. Please refer to the Installation Guide for full details of the installation process.

Security bracket

The sensor attachment allows for easy removal to change the batteries. For environments where the sensor needs to be held securely in place, a high quality stainless steel bracket is available. This allows attachment to any surface, and for the sensor to be easily removed by maintenance staff for battery changing or refurbishments. Universities normally require that a bracket is used.

Leak Sensing

The PCU monitors up to four leak sensors - positioned, for instance, under dishwashers, sinks or washing machines. The sensor sounds an alarm in the event of a leak being detected.

Telecare & BMS

Airis has two auxiliary outputs, each of which can be configured to alert telecare or BMS to one or more conditions, for example:

  • Airis cuts the power to prevent a fire
  • Water leak has been detected
  • No cooking takes place within a given time period
  • The proportion of interventions to cooking instances is greater than a given ratio
  • Airis intervenes more frequently than specified during installation
  • More than a specified number of interventions have taken place within a set time-frame
  • Fault detected

Airis Compared

Comparison with suppression

Prevention of fire and smoke

Airis greatly reduces the level of smoke with earlier intervention, especially important if a resident is asleep in the same area as the kitchen, as in a studio apartment. A frying pan can heat to a temperature well above the smoke and flash points of oil without ignition and thus a suppression based system cannot provide this protection.

Servicing and re-charging

Airis doesn’t require servicing to ensure its effectiveness and there is no need for recharging or cleaning up after a fire has been extinguished, because there is no fire. When Airis cuts the power to the hob, it can be immediately reset by the resident and cooking can continue with the resident protected.

Use with sprinkler systems

Airis and Airis-C can be fitted in 30 minutes. No specialist equipment or training is required and, uniquely, Airis configures itself depending on the type of cooker/hob it is connected to.

Use with sprinkler systems

Airis can complement the use of residential sprinkler systems. If the triggering of a sprinkler system is avoided even once, the investment in Airis will have been worthwhile in preventing potentially costly water damage.

Comparison with timers

Limiting cooking time is intrusive and frustrating for residents. A cooking fire can occur within a few minutes of putting a pan on from cold. Depending on the cooking technology this can be as little as two minutes. As soon as a resident leaves the kitchen, a fire can occur.

Timers and PIR devices do not meet the BS EN 50615 standard.

Device/Method Prevents a fire? Reduces smoke? Notes
Fire blanket or fire extinguisher Fire services advise against tackling stove top fires
Smoke alarm Smoke alarms do not prevent fires
Heat sensor Heat sensors measure the air temperature and rely on a fire having started
Extinguishing hood Extinguishing systems rely on a fire starting. They do not reduce smoke that precedes ignition
Safera Airis Prevents fires and greatly reduces smoke. Complies with BS EN 50615.

Accreditations & Compliance

Fire safety

The Safera Airis stove guard meets the requirements of BS EN 50615 Category B: Prevention of Ignition. The test certificate is available in Downloads.

Electrical regulation compliance

Please refer to the Declaration of Conformity, available in Downloads.

Electrical testing

1. Resilient to insulation testing at 500V.

2. The Airis Control Unit is double insulated and not earthed. It is therefore unaffected by earth loop impedance testing.
