Kitchen Guard Suppression

Designed for Studio, Open Plan and Student Apartment’s to reduce the kitchen hob risk and activate sounders throughout the apartment, thus allowing relaxation on the hob position and restrictions on the open plan area of the apartment.

 

Managing the risk

‘Hob Guard’ forms an extension of the intelligent apartment LD1 ceiling mounted detectors to provide local monitoring over the hob and isolation of the power source prior to hob ignition.

On operation of the Hob Guard unit in fire mode, the ceiling mounted sounders throughout the apartment are activated and the power supply to the hob, oven and worktop sockets are isolated to prevent a fire occurring.

The local hob detection provides an earlier response over that of the ceiling mounted heat detector thus improving detection times and getting the occupants moving earlier.

The Hob Guard is designed to detect and isolate the power supply prior to the fire occurring. The unit then operates the sounders drawing the occupant’s attention, thus designing the risk area out.

If for some unknown reason a fire occurs, the extinguishing system will be activated locally by an additional detection medium to extinguish the hob fire.

Hob Guard works by means of four sensors which monitor’s the hob constantly, raising a pre warning 15 second alarm when conditions approach an unacceptable level. Where no action is taken or conditions become critical, the Hob Guard is activated in fire mode to prevent the fire occurring.

Hob Guard comes from Norway where the Building Regulations require all kitchen hobs to be fitted with a monitoring Hob Guard in accordance with EN50615:2015 ‘Hob Fire Prevention Standard’, resulting in reduced numbers of cooking incidents since its introduction.

The Kitchen Guard Suppression concept was designed for Studio and Open Plan Apartments where the ‘Cooking Appliances’ opens to the living space giving Fire Engineers a tool to assist in presenting a case for designing the risk areas out and achieving greater flexibility with the open plan apartment area.

The extinguishing unit can be located up to 2m from the extractor hood which needs to be fitted with the gas manifold and detector. The system covers up to 4 electrical rings.

 

The Kitchen Guard Suppression system prevents accidents by first setting off an alarm and then shutting down the cooker, prior to releasing the extinguishing suppressant. This provides three stages prior to the release of the suppressant.
