Fireco Limited, manufacturer of the electronic fire door stay Dorgard, has expanded its in-house manufacturing facility to cope with rapid sales. The product is now established as a safe alternative to the dangerous practice of wedging fire doors open.
"We experienced an 80 per cent increase in sales over three months and were outgrowing the space we had at our Brighton premises," said managing director Chris Badenhorst. Demand for the product increased substantially as business managers became aware of their responsibilities under the UK Fire Precautions (Workplace) Regulations.
A new range of colours and Fireco's "Wedge Pledge" deal, which pays £5 for every wedge returned after the purchase of a Dorgard, is also contributing to the company's growth.
Fireco says that, unlike electro-magnetic retainers, Dorgard is battery-operated and does not require wiring to the mains or fire alarm. It is quickly screwed to the bottom of fire doors and, by depressing the rubber stopper which makes contact with the floor, doors can be held open.
The unit's audio electronic device listens for the sound of a fire alarm. When the alarm sounds the stopper retracts, allowing the door to close.
Integrate with security panels
KAC has added two new bases to its World Series family, which enables fire detection to be integrated into security control panels. The conventional photoelectric, combined photo-thermal and thermal detectors can be controlled from any security panel operating at 12v DC.
The low profile detectors operate at a voltage range from 8 – 30v DC, making them compatible with 12v DC security systems and 24v DC fire systems.
Measuring 102mm in diameter and 21mm in height, the 12v relay bases are available in latching and non-latching versions to allow the smoke detector to interface with technologies commonly used in intruder alarm control panels.
All bases covered
The El Professional El180 low voltage range of smoke alarms from Aico offers all the benefits of conventional Easi-Fit alarms and can be used with power supplies from 10 – 30v. The range also offers a full choice of detection technologies, comprising the El181 ionisation model, the El184 heat alarm and the El186 optical model.
A hush button is included as a convenience feature for users and prevents damage to the alarms. All three models come in an attractive, low profile, round design and make use of the company's Easi-Fit technology, which also allows easy installation.
The Easi-Fit mounting base allows for 16mm and 25mm trunking requiring no additional wiring enclosures or mounting kits. Alarms are connected using the built-in terminals and enclosure.
All the units come with or without battery back-uo and are supplied with integral relay, offering selectable continuous or pulse options.
Constantly monitors call points
Hoyles Electronic Developments claims its new Gemini GX32 fire alarm employs "unique concepts" to reduce installation costs. Each call point is powered by an integral PP3 alkaline battery and has an integral piezo sounder.
Due to a PIC micro-controller, each call point acts a self-contained manual fire alarm that constantly monitors neighbouring call points.A battery powered control panel is provided to enable the system to be silenced and to provide fault indication and trace facilities.
Twin red fire LEDs, a green system healthy LED and a yellow fault LED are also provided. The three-way key switch enables the system to be silenced, re-started or tested.
It is no longer necessary to use fire resistant cables for the independently powered call points. Even if the cables are cut or short circuited, it will continue to function as two or more systems. A specially manufactured low cost cable in red has also been developed for it. And the system comes in kit form, with and without ionisation smoke detectors.
Easy to upgrade or extend
System Sensor Europe's Series 300 conventional detectors are an easy-to-install simple and conventional range, which give the "sophistication" of an analogue addressable unit.
Comprising a multi-sensor photo-thermal unit, photoelectric smoke and heat detectors, all versions are backwards compatible with System Sensor's existing conventional bases, allowing upgrades and extensions.
Each detector can be given a numeric address which is displayed on a transition module during alarms so that the source of fires can be accurately identified. Other features include built-in automatic drift compensation and sensitivity adjustment via a remote programmer.
The detector allows chamber contamination levels to be read and the unit set into alarm from ground level, minimising commissioning times.
Open that door!
KAC has added three electro-magnetic door retainers for use in fire systems. Using power supplies of 24v DC or 240v AC, the units retain doors in the open position unless power is removed by the fire control panel. A spring-release ejector mechanism ensures that the magnetic force is overcome and the door is closed. All units are fitted with local manual override.
The 200 Newton DC version draws 25mA with a holding force of 20kg. The 500 Newton DC unit draws 45mA, while the mains-powered unit draws 7mA. Also, the door closers can be powered from the control panel or from a local PSU.
A sense of direction
The Directional Sound Evacuation is the "missing link in safe evacuation from buildings", according to Sound Alert Technology (SAT). It enables people to be led out of safe exits, even if visibility is totally obscured in smoke-filled rooms.The company has just signed a licensing agreement with Edwards Systems Technology of Connecticut, USA.
Combats dust build-up
System Sensor Europe’s ECO1000 range consists of a photoelectric detector, a combined photo-thermal unit and fixed and rate-of-rise thermal detectors. The photoelectric and photo-thermal detectors have automatic drift compensation, allowing them to offset changes in sensitivity arising from the build-up of dust. They also use on-board digital signal processing and a new optical chamber design which increases stability while maintaining sensitivity. Installers also benefit from a laser-based remote test. The ECO 1000 range comprises a multi-sensor unit that responds to smoke or heat or a combination of both. A microprocessor running sophisticated algorithms provides a fast response to real fires situations. And a combination of photoelectric and thermal characteristics reduces the risk of unwanted alarms. All models operate at 12 and 24v DC and meet EN54 parts 5 and 7 standards.Source
