Passive Infrared Sensors (PIRs) for Lighting, Ventilation, and Heating

The PIR – Passive Infrared Sensor – is an electronic sensor that measures infrared (IR) light radiating from objects in its field of view and then trigger a certain action in a device or light fitting. They are most often used in PIR-based motion detectors, and they work in conjunction with lights, heating, ventilation, etc.

Their main purpose is detecting the presence (or absence) of a human being (or a pet) in a certain area, and then switching ON or OFF the light, the fan, or the heat. The PIRs are of different kinds depending on the lighting loads, location (indoor or outdoor, wall or ceiling), IP rating, usage, etc. Some PIRs are integrated with the fitting: some light fittings come complete with a PIR sensor, and some fans have a PIR integrated for presence or motion detection.

On our website at we have quite a large range of PIR sensors – the standalone units – to help you save energy and make sure you don’t waste money just because you forgot to turn the light or the fan off.

Ceiling or Wall PIR Detectors from CP Electronics

Ceiling or Wall PIR Detectors from CP Electronics

CP Electronics has quite a wide range of PIRs. One of them is the batten mount PIR, a miniature PIR that has been specifically engineered for mounting directly onto a batten style luminaire (see EBMPIR-MB), while another one is a retrofit PIR that allows previously uncontrolled lighting sources to benefit from presence detection and lux level (see EBMINT); these are both ceiling mounted PIRs.

For ceiling flush mounting CP Electronics has the GEFL PIR movement sensor that provides automatic control of lighting, heating, or ventilation loads, having a low profile and being almost un-noticeable on the ceiling.

If you prefer a wall-mounted PIR, the PDS-PRM no neutral wall mounted presence detector combines the PIR presence detection with a time delay function – it ideally replaces a wall switch so that, when the presence of a person is detected, the light turns on automatically.

PIR Occupancy Switches from Danlers

PIR Occupancy Switches from DanlersThe Danlers range of passive PIR infra-red occupancy switches is designed for the automatic control of lighting, heating, ventilation or air conditioning loads. How it works: the PIR switch will switch on the connected load automatically when an area is occupied, and then switch it off automatically when the area has been vacant for a chosen duration.

This has the benefits of reduced energy bills and automatic control. When being used to control lighting, the built-in photocell can be used to keep the lights off on bright days.

Among the most popular ceiling flush PIRs from Danlers are the CEFL PIR (ideal for false or plasterboard ceilings) and the CEFL Sealed version (ideal for bathrooms and damp areas, sealed bathroom version). They also provide a wide range of batten mounted PIRs with the new “intelligent” photocell and a range of 5-10m detection; they are cost-effective solutions.

Furthermore, they have some ceiling directional PIRs (which can be rotated and lowered, ideal for corridors and aisles), wall PIR detectors, and even some PIR occupancy switch modules (ideal for building into luminaires and for wall/ceiling mounting).

Other PIRs: mini PIR, Outdoor PIRs, and Integrated PIRs

Besides these two main British Manufacturers of PIR detectors and sensors there are many others, such as the outdoor BB2002 black outdoor wall-mounted PIR (up to 2000W, covers approx. 10m range, can be manually operated) and the BB3027 (2000W black PIR for corner-mounting outdoor, 270 degrees, 10m coverage).

For indoor lighting control and with a £1 size is the BEG Luxomat PD9 – circular detection area, ceiling mounted or directly built-in lamps, or the ceiling mounted PD3FC circular mini occupancy detector which can be remotely controlled. For small spaces such as wardrobe lighting you can always use the LEDPC in-line photocell for LED striplights or the PIRSENSO mini PIR motion sensor for switching ON/OFF the lights up to 250W (10 sec – 3 mins PIR cupboard switch).

The choice is yours: where and for what do you need a presence detector? Is it for indoor or outdoor? Is it for LED lamps, fluorescent fittings, or regular halogen or incandescent lamps? Take a look at the PIR solutions we at Sparks can offer you, and let us know if you need more information!

Debunking the most Common 6 Myths on Electrical Floor Heating Installation

Debunking the most Common 6 Myths on Electrical Floor Heating InstallationFloor heating has been known and loved by many for a very long time now. Even ancient Romans liked this simple comfort and used circulating warm water under their marble floors in order to have warm floors. Nowadays the electrical floor heating solutions provided by DEVI are not only comfortable but also energy-efficient with a huge focus on environmental friendliness.

However, we often hear a lot of myths about floor heating, and many of them concern installation. Let’s dispel the most common six myths about electrical heating installation.

Myth 1: Electrical floor heating is complicated to install.

Not true. Heating mats are a solution which can easily be mounted whether it is on new or old sub-floors. The installation time will be the same, regardless of the type of flooring under which the system is installed.

Also, the heating cables offered by DEVI are also easy to install especially when the new designed DEVI Turntable is used. Installers proved that using the DEVI Turntable makes the installation of the DEVIflex or DEVIsafe cables much faster and easier.

Myth 2: Floor heating can only be used in bathrooms

Wrong! Electric floor heating can be used in all types of rooms such as bedrooms, kitchens and hallways. Nowadays, thanks to the modern thermostats (such as the DEVIreg Touch), floor heating is often used as a reliable and energy efficient solution of choice for all types of buildings (including the low-energy houses).

You can easily install electrical floor heating in newly built houses as well as existing ones during renovation. The DEVI floor heating is often preferred and installed in residential, apartment blocks, renovated buildings and public buildings.

Myth 3: Electric floor heating can only be installed under terracotta

Wrong again. Floor heating can be installed under lots of different types of flooring. DEVI electrical heating solutions do not take up any space, which gives an opportunity to design a space in each room as you please. You can install the DEVImats under any wooden floors, concrete floors, or even laminate floors.

Myth 4: A fault means that you have to rip up the whole floor

Not quite. The DEVI heating cables have a very long life time; they come with a 20 year warranty. But in case of any misfortune there is no need to rip up the whole floor. The problem can be pinpointed to a few centimeters of accuracy, so that only one or two tiles (for example) has to be removed to make a repair possible.

Nevertheless if this needs to be done, in a case of rare fault, the DEVI warranty of 20 years covers full floor repair.

Myth 5: Using electrical heating is the most environmental unfriendly way of heating

Not true. An electrically heated house with electric floor heating and solar cells fulfills the requirements of the EU Building Performance Directive. The electrical house is cost competitive since it needs no other energy sources apart from electricity and fresh water.

This is why nowadays electric heating is the solution of choice for low-energy houses. Regarding the fact that the EU expects that 65% of electricity production will come from solar cells, wind and nuclear energy in 2020, electrical heating is clearly the preferable choice. Improving the energy performance of buildings is a particularly critical step in reducing the EU’s carbon footprint.

Myth 6: Using electrical heating for outdoor heating is a high cost solution

Not really. For example, the DEVI outdoor heating systems are equipped with energy-efficient and cost reducing, advanced intelligent thermostats that automatically regulate the system based on the actual temperature and humidity conditions. In cold but dry weather, the system remains inactive, saving energy and costs. When the weather is cold and wet, the system is automatically activated, quickly melting snow and preventing the build-up of ice. Nevertheless, you always have the option to manually control the system via the thermostat.

An outdoor heating system from DEVI is quick to install, easy to control and inexpensive to operate. The desired snow and ice prevention effect can be fully achieved by installing cables only in those areas that are most susceptible to major build-ups of snow and ice, for example where buildings meet each other, around exposed downpipes or at points where the most melt water is channeled.

The Perfect Green Deal Bathroom Ventilation Fans: the Airflow LOOVENT Eco!

With over 40 years of experience in manufacturing and selling airflow ventilation systems, Airflow has a wide range of bathroom fans and kitchen fans, including the LOOVENT Eco range.

The Perfect Green Deal Bathroom Ventilation Fans: the Airflow LOOVENT Eco!

Continuing its range of LOOVENT fans of “legendary reputation” since 1969 or so, Airflow has transformed this range into a modern 2-speed ECO version for a safer, cheaper to run, low energy, and more modern bathroom ventilation.

With a discreet style in a modular design, extremely easy to install and maintain, the LOOVENT Eco bathroom centrifugal fans are quiet and come with either a timer, a humidity timer, or a motion sensor with timer.

The Airflow 72684305 timer version for example allows you to set the run-on timer between 2 and 24 minutes, and you can select a delay of two minutes after the light is turned on in the bathroom.

This fan can be connected to the light switch, and it comes with a momentary pull-cord switch as a “manual boost” override for you to switch to the second speed (the standard speed is the first one).

The Airflow LOOVENT eco range of fans is great for bathrooms and toilets where the duct runs are long, since the centrifugal impeller is powerful enough to move air over longer distances when met with pressure resistance from ducting.

The Airflow Loovent ECO fans can be installed in Portrait or Landscape in the Bathroom or Toilet

With an ingress protection rating of IPx5, these fans are suitable for use in zone 1 or 2 with a 30mA RCD (as defined in Section 701 BS7161:2008 IEEE Wiring Regulations, 17th Edition). They also comply with the latest Building Regulations, Approved Document F (part L).

The Airflow Loovent ECO fans can be either wall mounted or ceiling mounted, as needed.

This range of bathroom fans successfully replaces the old style (very popular) LOOVENT fans; the spigot position is identical and the back plates are the same size (reworking is thus minimum).

Airflow LOOVENT Eco Bathroom Fans – Features and Benefits

  • Economical to operate: the “low setting” uses only 3.5W to provide continuous ventilation, the “high speed” 12W (for “boosting” the ventilation). Cheaper to run.
  • High extraction rate: 62 m³/hr at low speed, 110 m³/hr boost.
  • Very quiet running: 29 / 47 dB(A) at 3m.
  • Low SPF: only 0.21 / 0.40 w/l/s
  • Compact design: modernised curved edge design.

  • Green Deal: The LOOVENT eco dMEV version will be the perfect solution for the “Green Deal” which is the latest Government innitiative and ideal if you have added aditional insulation to your home. This fan will combat any problems with condensation and mould and remove any odours that may occur.
  • Ducting: 100mm / 4 inch fan.
  • Fan dimensions: 187 mm width, 167 mm height, 138 mm depth.
  • Double insulated: does not require an earth connection.
  • Mounting: can be surface or recessed, portrait or landscape, as needed.
  • Location: it is important to locate this fan in the best location for an optimal performance, ideally at the furthest point away from where the replacement air enters in the bathroom.
  • IP rating: IPx5, suitable for use in the bathroom (zones 1 and 2)
  • Mains voltage: 100 / 240V – 50/60Hz single phase supply.

LOOVENT Eco Fans – a Fan for Every Application!

  • New Build: LOOVENT eco gives the Specifier of ventilation for new dwellings the opportunity to select low energy efficient intermittent extraction in toilets, en-suites, bathrooms, utility rooms and kitchens in compliance with the latest Building Regulations. For better sealed houses and those Specifiers implementing a decentralised, whole house ventilation strategy the continuous ventilation dMEV model is the ideal choice.
  • Repair and Refurbishment: From simple DIY to planned upgrade and refurbishment the LOOVENT eco provides proven performance with outstanding reliabilty and functionality. Built on the pedigree of over 2 million Loovents sold since it’s introduction in 1969, the next generation LOOVENT eco even has the same mounting points and offset spigot position of its predecessor making it quick and simple to replace.
  • Social Housing: It is not only low energy, but incorporates quiet operation and good value that concerns Social Housing Specifiers. With the move away from ad-hoc repairs to longer term planned maintenance programme the Asset Manager has his eye on long life components that require minimal ongoing maintenance, LOOVENT eco with ball bearing motor technology provides the assurance of many years of trouble free operation that can be relied upon for inclusion in their MRS planning.

And the good news is that, for a limited period of time, you can purchase the LOOVENT Eco 4 inch 72684305 with timer and the version with humidistat 72684306 at a lower price than usual.

If you’re a LOOVENT fan or you need a high quality centrifugal ventilation fan with low noise operation, energy saving ECO credentials, low cost maintenance, and complying with the Green Deal requirements, you should definitely check these fans out at Sparks!
