arper Adams University in Shropshire has installed Aico’s 160e Series of mains powered Smoke Alarms into its student


accommodation in a move to increase levels of protection for students. Harper Adams University is a specialist


provider of higher education for the agricultural and rural sector. It has more than 4,000 students, a large number of whom live on campus in halls of residence and other properties, including semi detached cottages. These cottages – around 27 in total, each with


four to five bedrooms – already benefit from Aico Smoke Alarms in the landing and hall. The University wanted to increase the level of


Toshiba’s new air conditioning controller takes innovative approach to energy savings


T


oshiba’s new generation Black Pear air conditioning controller provides end users with new ways of saving on


energy running costs, plus a comprehensive set of control and monitoring functions. For the first time, the RBC‐TSI1 Black


Pear has a range of inbuilt modes that can be selected to match particular applications. These include integration with higher level Building Management Systems via voltage and resistance, with discrete inputs on Modbus, and special modes for use in multi‐occupied buildings. Hotel Mode gives end users a pre‐set


setback option, which can be integrated with a key card window switch. This minimises energy use while delivering optimum cooling and heating to the room, for maximum guest comfort. There are two Eco modes, one based on a timed fan operation, enabling the unit to run in an operating mode for a pre‐ determined period of time; the other allows the use of two set points, to cover heating and cooling, again helping to minimise energy use while maintaining optimum comfort conditions. Suitable for application with Toshiba


VRF, light commercial splits systems, and VN ventilation systems, the RBC‐TSI1 has multiple uses, making it highly flexible and adaptable. These include: uDirect connection to TCC‐NET 2‐wire A/B network.


uSix analogue inputs selectable as voltage or resistance.


uRun/error indication. uRS‐485 connection. uMonitoring and control via serial Modbus.


uModbus address range 1 to 254. uUp to 16 units can be operated in a Master/Follower configuration.


uUp to 8 units on a single link, providing detailed information on each unit. Fraser Hymas, head of control systems at


Toshiba, who lead the development, said: “The new Black Pear packs a lot of capabilities and options into a small package. We believe its pre‐set energy saving modes will be highly attractive to hotels, in particular, where sporadic occupancy – both during the day and day‐ to‐day – presents significant opportunities for energy saving.” He added: “For contractors, the fact that


it can be used pretty much across our product range means that, once they are familiar with the system and the simple set‐up steps, they can apply with confidence to most installations and get the benefits of ease‐of‐use, flexibility and energy savings for customers.”

olypipe’s latest Professional Development Centre, offering training across a range of Polypipe products, has been extended to


include domestic ventilation. Based at Polypipe Ventilation’s head office in Kirk Sandall, Doncaster, the new centre is a bright and spacious double height glazed building which provides installers and distributors with all the facilities necessary to gain an in‐depth knowledge of Polypipe’s solutions and product offering. The Polypipe Ventilation equipment on


display at the centre includes energy saving, whole house Silavent Mechanical Ventilation with Heat Recovery (MVHR) and CMX


Mechanical Extract Ventilation (MEV) units; Domus rigid and Radial semi‐rigid duct systems and accessories; Silavent Positive Input Ventilation (PIV) to address condensation in existing properties; plus an extensive display of Silavent bathroom and kitchen fans, covering intermittent axial, in‐line and centrifugal extract fans and dMEV units. As the proud recipient of a number of


prestigious industry awards, including most recently the Housebuilder Best Services Product award for its Domus Green Line high efficiency rigid duct bends, Polypipe Ventilation has dedicated a section at the new centre to highlight its success and the associated products.

ir Vent Technology, an established manufacturer of air handling and heat recovery units, has set up a new department for the


protection, but without the considerable expense of moving to an LD1 system which is the highest protection in Fire Alarm system categories. It also wanted a solution that was flexible as these properties may be repurposed in the future. The solution was found in the use of Aico’s Ei160e Series mains powered alarms with 10‐year rechargeable Lithium cell back‐up with Ei164e Heat Alarms fitted in the kitchens and Ei166e Optical Alarms in the bedrooms. Delivering the highest level of protection for BS 5839‐6 Grade D applications, the 160e Series is compatible with existing Aico alarms and accessories.

WHAT’S NEW BSEE


KalGUARD offers maximum benefits for limescale control


and hotels. If left unchecked, limescale can lead to problems such as higher energy bills (British Water estimates that just 1.6mm of limescale can increase a heating system’s fuel requirement by up to 12%), as well as premature repairs, breakdowns and replacement of secondary hot water system components and appliances, business downtime, and unnecessary, unplanned capital expenditure. To inhibit the buildup of limescale, KalGUARD® from Sentinel


L


Commercial is a scientifically – and independently‐proven – limescale control device which uses unique driven electrolytic technology. What’s more, KalGUARD is arguably the best limescale control device on the market in terms of overall cost‐effectiveness, performance, ease of installation and maintenance.


The only methodology approved in Part L


KalGUARD, which comprises a zinc anode unit, water meter and controller, permanently ‘conditions’ water by dosing it with a very low level of stable zinc. This is achieved via a controlled electrolytic process, which uses a powered zinc anode and a copper cathode, forcing naturally‐occurring calcium carbonate crystals to form as soft, non‐ deposit‐forming aragonite rather than hard, deposit‐forming calcite (limescale). Electrolytic technology is the only powered device‐led methodology to


be recommended by UK Building Services Compliance Guide to Part L. Furthermore, independent testing undertaken at Cranfield University has proven KalGUARD’s ability to reduce limescale.


Permanent limescale prevention


Forget temporary limescale control – KalGUARD continuously alters the chemical composition of calcium carbonate crystals for long‐lasting protection and complete peace of mind.


Not LSI dependent


KalGUARD does not rely on water chemistry and ambient temperature having a positive Langelier Saturation Index (LSI), so there is never any need for extra units or additional water analysis and liaison between manufacturer and designer. As a point of note, KalGUARD can be designed on demand, not just according to pipe size.


One KalGUARD treats an entire system


WRAS‐approved KalGUARD is able to treat an entire system when installed on a rising main before pump and booster sets, providing a value‐engineered solution to limescale control. There is no need for additional units to be purchased and installed at more than one location, such as where water draw‐off is sparse and spasmodic.


Maximum flexibility


KalGUARD is proven to be suitable for successful use in conjunction with all types of heaters from leading OEM providers; there is no restriction for use with high heat flux density water heating equipment, such as continuous flow heaters, for example. This provides maximum flexibility for the designer or consulting engineer on choice of heater.


Minimal maintenance


Once commissioned, KalGUARD requires only a bi‐annual service if the system filter is fitted. Moreover, no consumables are needed for its ongoing operation, while the zinc anode lasts up to 12 years. KalGUARD comes in a range of sizes, from 22mm through to 108mm.


The system is already installed in thousands of commercial facilities across the UK, including those belonging to major supermarkets, leading hotel chains, universities, and international fast food outlets, providing proven energy, cost, and time saving limescale control.
