The recently released BA 295 compact backflow preventers from Honeywell are designed to ensure contaminated water cannot flow back into the public mains supply.
The valves are designed to meet the requirements of the UK Water Regulations Advisory Scheme (WRAS) and use the well-proven RPZ -reduced pressure zone principle.
They are suitable for industrial and commercial premises, and for residential buildings within the scope of their specification.
They protect drinking water systems against back pressure, back flow and back siphonage ensuring compliance with relevant water regulations.
The new DU144 automatic bypass valve from Honeywell provides a cost-effective means to satisfy the boiler bypass requirements of 'Good Practice Guide 302', part of Building Regulations Part L1.
It has an adjustment mechanism that increases water flow automatically according to the water pressure across it. As the rooms reach the desired temperature and the valves close, the valve opens proportionally to enable safe water flow around the boiler. When valves reopen, it closes and flow is redirected from the bypass to the heating loop.
Boasting a large, ultra-clear 'Line of Text' display and simple on-screen instructions, the latest room thermostat offering from Honeywell, the company says, will facilitate easy installation and control.
The new CM900 provides 'obvious' instruction throughout the operating process, allowing users to know exactly at what stage they are and what needs to be done next. The company said the aim was to render the instruction book unnecessary for both users and installers.
The CM900 allows for up to six time/temperature changes each day, meaning that it can be tailored to fit in with everyone's lifestyle in any setting. It also offers three comfort-enhancing, energy saving overrides with a simple touch of a button. These include a 'Holiday' setting, 'Party' setting, and 'Day Off' setting, each offering an array of different options.
Available as wireless or wired, the system is suitable for radiator and underfloor heating, integrated with gas or oil-fired boilers including condensing and combination models, as well as electric heating or cooling systems.
Featuring a mobile keypad, Honeywell has launched the new EN 50131-1 compliant, Domonial wireless intruder alarm system. The new TCU2-800M mobile radio keypad has an LCD display which provides operation instructions for each function as well as information about the status of the alarm.
Pressure reducing valves from Honeywell have been installed in HM Prison Peterborough. The valves silently balance water pressures to prison wings and to individual floor levels, ensuring water pressures and supplies to each cell block. A DR300 series flanged valve reduces pressure to six bar at high and low flow rates. Smaller D06F valves with screwed connections maintain three bar at each floor level.
Having campaigned to raise awareness of the dangers of scalding water in bathrooms, Honeywell has welcomed the ten minute rule tabled by Mary Creagh MP.
The rule calls for thermostatic mixing valves on all new baths to prevent scalding hot water from taps.
Children and the elderly are at increased risk of scald burn, though these are wholly preventable, says Honeywell.
People who are physically and mentally impaired are also at risk. In healthcare, valves certified to Buildcert TMV3, such as Honeywell TM200VP, must be fitted.
Valves to the domestic TMV2 standard, such as the company's TM300, are acceptable for most other premises but a risk assessment should be carried out to determine if the facilities are to be used by vulnerable people.
Linkage kits from Honeywell allow its SmartAct direct-coupled actuators to be mounted to three or four port rotary valves. It is suitable for operating air dampers, ventilation flaps and variable air volume units. The kit features an internally profiled connector that locates firmly onto a D-shaped valve stem with a self-centring shaft adapter, detachable wiring box, rotation direction switch and a position indicator.
Helping strike a balance between smoking and non-smoking at the Garsdale Country Inn near Bury are two Honeywell air cleaners. Licensees David and Gillian Heyes said that, with the air cleaners, smoke cannot be detected even when people are smoking. One air cleaner ensure a 'smoke free' atmosphere in the bar area, the second ensures the lounge remains pollution free.
Suitable for both underfloor and radiator heating, as well as hot water in large buildings, Honeywell has introduced Smile, a new heating controller. Smile has a user panel with large back-lit LED display and a single rotary control that is also a push button. It is designed to make it easy to select, change and confirm set values and times - and difficult to make mistakes. The controller has a built-in weather compensated control which responds to outside temperatures to ensure comfort and economy. Users can program and select separate heating profiles such as ?economy?, ?holiday? and ?party?.
Kingsteignton Youth Centre in Devon is claimed to be saving almost ?3,000 per year on gas bills ? a reduction of over 80%? and has also cut its electric bill, thanks to a heating system upgrade by local specialist The Stove Shop using Honeywell controls. The Stove Shop installed seven CM67 programmable controllers in the Youth Centre, one for each of seven heating zones. Three CM67s are in the boiler room to serve rooms at the end of that building, the other four within a heating cupboard on the other side. Individual times and temperatures for each zone are programmed to change automatically at various times during the day, so that rooms are heated to the appropriate temperature for the activity. It is also possible to override a set temperature, if necessary. The controllers have a built-in ?optimum start? feature which saves energy by allowing the user to set the time at which the desired temperature is to be reached, rather than the heating ?on? time, so reducing fuel consumption on all but the coldest of days.
