Yes, our FireAngel Specification range and FireAngel Mains 9V range of alarms are suitable for all domestic properties, this includes rental and new build properties

Whilst BS 5839-6 has previously been split into six varying Grades, each outlining the level of protection appropriate for certain properties and their corresponding levels of risk, the new update has altered the six sections, removing Grade B and Grade E, whilst Grade D and Grade F have been split into Grade D1 / Grade D2 and Grade F1 / Grade F2 respectively. Grade C has been revised and its recommendations expanded.

The 2019 grading system is as follows:

Grade A

Separate detectors, sounders and central control and indicating equipment with back-up power supply that conforms to British Standards BS EN 54.

Grade C

Separate detectors and sounders that are mains powered with back-up power supply and central control equipment.

Grade D1

A system of one or more mains powered detectors, each with a tamper‑proof standby supply consisting of a battery or batteries (such as FireAngel’s SM-SN-1 and HM-SN-1 alarm).

Grade D2

A system of one or more mains-powered detectors, each with an integral standby supply consisting of a user‑replaceable battery or batteries. (such as FireAngel’s SW1-PF-T and HW1-PF-T alarm).

Grade F1

A system of one or more battery-powered detectors powered by a tamper‑proof primary battery or batteries (such as FireAngel’s ST-622, ST-750 alarm).

Grade F2

A system of one or more battery-powered detectors powered by a user‑replaceable primary battery or batteries. (such as FireAngel’s SB1-T alarm).
Please note: Grades B and E are no longer defined in BS 5839-6:2019.

BS 5839-6:2019 outlines where fire detection systems should be installed per category with additional recommendations to install heat alarms in kitchens. There are three categories for fire detection and fire alarm systems LD1, LD2, LD3.

‘LD3 Minimum Protection’ covers escape routes only.

LD3 protection is a system incorporating detectors in all circulation areas that form part of the escape routes from the premises. Smoke alarms should be installed in all circulation spaces that form part of escape routes such as hallway and landing.

Note: This minimum category now only applies to owner-occupied bungalow, flat, single-storey unit or maisonette with no floor level above 4.5m from ground level or owner-occupied two-storey house.

BS 5839-6:2019 outlines where fire detection systems should be installed per category with additional recommendations to install heat alarms in kitchens. There are three categories for fire detection and fire alarm systems LD1, LD2, LD3.

‘LD2 ADDITIONAL PROTECTION’ covers escape routes plus high risk rooms

LD2 protection is a system incorporating detectors in all circulation areas that form part of the escape routes from the premises, and in all specified rooms or areas that present a high fi re risk to occupants, including a heat alarm in any kitchen and a smoke alarm in principle habitable room(s). This includes Hallway, Landing, Living Room, Kitchen (Heat Alarm).

Note: This is now the new minimum category for all rented properties and must include a heat alarm in the kitchen and a smoke alarm in principle habitable room(s).

House

BS 5839-6:2019 outlines where fire detection systems should be installed per category with additional recommendations to install heat alarms in kitchens. There are three categories for fire detection and fire alarm systems LD1, LD2, LD3.

‘LD1 Maximum Protection’ covers escape routes, high-risk rooms plus all areas where a fire might start.

LD1 is the highest level of protection of all occupants who might occupy the dwelling over the lifetime of the fire detection and fire alarm system. A system installed throughout the premises, incorporating detectors in all circulation areas that form part of the escape routes from the premises, and in all rooms and areas, other than those with negligible sources of ignition, such as toilets, bathrooms and shower rooms.

To meet LD1 standards you should fit alarms in the following rooms: Hallway, Landing, Living Room, Kitchen (Heat Alarm), Bedroom, Airing / Meter Cupboards, Loft, Garage.

No, you need should refer to BS 5839-6 latest guidance which recommends fitting a heat alarm in a Kitchen. The enhanced heat sensing element within our range of heat alarms is designed to alert for common kitchen fire and is less prone to nuisance alarms when cooking. A high number of false alarms caused within a kitchen are due to incorrect placement on smoke alarms – smoke alarms are not suited for kitchens and should be fitted within hallways, landings, bedrooms, dining rooms and living rooms.

No, our Specification range is not compatible with our Mains 9V range of products. Our Specification range of alarms feature a 10 year sealed long-life lithium battery whereas our Mains 9v range feature replaceable batteries and Push-Fit installation.

Thermistek heat alarms are recommended for placing directly in kitchens as they won’t nuisance alarm from cooking fumes and in unconverted loft spaces or garages where there may be high levels of fumes or dust.

The heat alarm has a unique radiant heat dish which reflects directional heat from the fire onto the thermistor allowing a faster reaction to fire than conventional heat alarms.

It also constantly monitors for temperature change using a predictive algorithm.

If an increase in temperature is detected, the rate of rise is measured and if predicted to exceed a predetermined threshold will sound the alarm. This predictive quality provides a quicker response time in rapidly increasing temperatures.

Thermoptek is a type of smoke alarm sensor technology and is used in FireAngel’s Specification range of mains and battery powered Multi-Sensor smoke alarms, which is used and recommended by over 90% of the UK Fire and Rescue service.

Thermoptek technology provides a much faster response to fire, giving housing occupants more time to escape should a fire occur. This technology is available at an affordable price, and is sold at a similar cost to some other single-sensor units that are available.
