This greatly reduces the number of points that need to be installed and the time it takes to install.As the Twinflex Multipoint ASD offers 7 different modes of detection, the installation is made even simpler since one device suits all applications.Whatever type of detection is required, it can be selected by the flick of a switch at the time of commissioning 3 different smoke modes, 2 fixed temperature heat modes, a rate of rise mode and a combination smoke or heat mode. The Twinflex Multipoint ASD is available with or without a full specification integral 90dBA sounder no extra devices need to be purchased when an audible warning is required. If extra sound is required or for areas that do not require detection, then a choice of several different standalone sounders or sounder beacons can be used on the same two wiresThe Twinflex Multipoint ASD Detector - Detection ModesTwo-wire installation - only one circuit per zone to connect detectors and sounders - installation savings can be as high as 40%. There are 7 modes of detection.The Twinflex Multipoint ASD saves the cost of a sounder. Warning of head contamination, before going into false alarm. Easily removable for maintenance at height. The Twinflex Multipoint ASD Detector detection modes are:Smoke 1: Used where ionization detectors are normally fitted, especially when there are high ceilings or a risk of free-burning fires (chemical stores etc), or fires that need to be detected extremely quickly.Smoke 2: Used where optical detectors are normally fitted, when there is a risk of a smouldering fire and for escape routes.Smoke 3: Designed for use in areas that are prone to nuisance alarms. The reduced sensitivity linked with a time delay feature means that a higher concentration of smoke needs to be present for a constant time period before a fire decision is made.Heat 1: (Rate-of-Rise) – Used where a standard rate-of-rise detector would normally be used.Heat 2: (Standard Fixed Temperature – 58°C /136°F approximately) – A standard fixed temperature heat detector, suitable for domestic kitchens, etc.Heat 3: (High Fixed Temperature – 90°C / 194°F approximately) – High fixed temperature heat detector suitable for boiler rooms, commercial kitchens, etc.Fike Twinflex Pro2 - Alarm Confirmation FeatureEarly warning fire alarm verification is often crucial. The disruption to business and costs associated with responding to false alarms can be enormous. The TwinflexPro2 offers alarm confirmation technology, which can help eliminate nuisance or false alarms.Using the built-in alarm confirmation feature, until an alarm has been confirmed within an individual area, only that area is evacuated. At the same time, if an alarm is triggered in a common area, the device initiates a full alarm evacuating all surrounding areas. This unique panel feature is vital where two-stage alarms are required.For example - when an alarm is indicated by an individual detector, the sounder for that device/zone is activated and the control panel carries out the configured number of confirmation checks on that specific zone.If the alarm is confirmed, the control panel enters the fire state and all additional notification devices are activated throughout the facility. If the detector alarm is rejected, the sounders on the zone are silenced, and the detector in alarm is reset.For safety, activating a call point will override any delays or confirmation settings.Twinflex Pro2 Detectors and AccessoriesHere are the Twinflex Pro2 Detectors and Accessories - many of which can be found on our website for purchase.Twinflex Multipoint ASD Detector (Fike 204-0003)A multifunction smoke and heat detector with three smoke detection modes, three heat detection modes and one combination mode.

The specifiers and the installers who choose the Multipoint detector do so secure in the knowledge that the fire detection performance of the detector can be matched to the environment in which it is installed –and changed at any time during the lifetime of the installation. With the Sita 200 plus System, a high technology approach has been adopted, with a microcomputer in each detector implementing a large degree of distributed intelligence. The system can support 200 Multipoint combined detectors/sounders on a single loop. Each one not only provides detection but also the option of a built-in sounder. Integrity of the system is maintained by way of a built-in isolator in each device. The Rafiki Sita system intelligence has been harnessed in such a way that the equipment used is very easy to install, commission, and maintain. The system has been designed to high specification and quality standards and is intended to fully comply with the new EN54 -2 and EN54 - 4 standards and EU directives. Rafiki Multipoint Sita - Main Features Fast short circuit isolator in every device; 15 combinations of smoke & heat detection modes; Multi-stage alarms - pre-alarm feature; 7 sound patterns - plus off, 3 different volume settings – if using Sita Multipoint with integral sounder; Auxiliary digital inputs and outputs are available at any Addressable Multipoint device; Automatic continuous self-calibration; Addressable Multipoint detector is monitored for all failures of the sensor chamber - a warning is indicated when a smoke detector head requires servicing; Maintenance is made easy with the unique disposable optical chamber, designed as a cost-effective solution to cleaning and re-calibration; All modes are compliant with European detector-type specifications, and are suitable for use in installations compliant with BS5839: Part 1: 2002; More details about the Rafiki Multipoint: eliminate the false alarms; more on the Rafiki detectors; The Multipoint Detector; new Multipoint ASD detectors, and the modes of detection. Rafiki Multipoint Sita - Modes of detection SMOKE 1: Highly thermally enhanced optical Used where ionization detectors are normally fitted, especially when there are high ceilings or risk of free-burning fires SMOKE 2: Thermally enhanced optical Used where optical detectors are normally fitted, when there is a risk of a smoldering fire and for escape routes. SMOKE 3: Thermally enhanced optical with pulse rejection Used where optical detectors are normally used in positions exposed to brief concentrations of water vapor or smoke e.g. from a bathroom, kettle etc. HEAT 1: Rate of rise to 58°C Used where a standard rate of rise detector would normally be used HEAT 2: Low fixed temperature 58°C Used where a standard fixed temperature heat detector would normally be fitted, suitable for kitchens, etc HEAT 3: High fixed temperature 90°C Used where a high fixed temperature heat detector would normally be fitted, suitable for boiler rooms, etc. Combinations Any combination of smoke and heat modes may be selected, and differing alarm responses selected for each mode. If the Multipoint with an integral sounder is required, then it too can be set to a choice of 7 different sound patternsBuy Fike Fire Detectors at Sparks

This article is the continuation of the, new Multipoint ASD detectors from Rafiki(short introduction) previously posted on our blog. Via this article you can find out more about the automatic calibration and the modes of detection offered by the Rafiki MultiPoint detectors (heat and smoke detection modes). All modes are compliant with European detector type specifications, and are suitable for use in installations compliant with BS5839: Part 1: 2002, Part 6 2004 if used in conjunction with a "Twinflex Plus" system. The Twinflex Intelligent conventional detector can be set to any one of the smoke or heat detection modes as well as a Combined Mode (Smoke 2 & Heat 2) where a smoke or heat source can trigger a fire decision. This means the end user is given optimum fire protection, even if the installer is unsure of the use of the particular area where the detector is sited. As part of the Twinflex system, all the Twinflex products including the Twinflex Multipoint detector feature an End of Line monitoring switch, which negates the need to install End of Line monitoring resistors. The Sita Intelligent addressable detector is able to offer all the choices for detection or a combination of any listed to give a choice of up to 15 different settings. It is set via a PC when programming the system. The Sita Multipoint also has an in-built loop isolator as well as an input/output facility for local control and switching. The Multipoint Detector also has the unique benefit of an optional full-specification integral sounder. A 90dBA output can be achieved. The Twinflex Intelligent two-wire detector can be set to 3 different sound patterns, as well as switched off, with 2 sound output levels. The Sita Intelligent addressable detector has 7 different sound patterns and 3 volume settings. Automatic Calibration To ensure the detection capabilities of the Multipoint are never compromised it self-calibrates every 6 hours. It continuously monitors for dust contamination, until, over a period of time, depending on the environment, it reaches a point where the chamber becomes saturated. Before this can develop into a false alarm situation, the panel will indicate that a Multipoint needs attention on both the Twinflex and Sita systems. To make maintenance easy, the Multipoint features a disposable optical chamber. This means the chamber can be simply thrown away, and replaced economically when necessary. Rafiki Multipoint Reflected Optical Value The Rafiki MultiPoint detector - modes of detection Smoke 1: Used where ionization detectors are normally fitted especially when there are high ceilings or risk of free burning fires (chemical stores etc), or fires that need to be detected extremely quickly. Smoke 2: Used where optical detectors are normally fitted when there is a risk of a smoldering fire and for escape routes. Smoke 3: This setting is designed for use in areas that are prone to nuisance alarms. The reduced sensitivity linked with a time delay feature means that a higher concentration of smoke needs to be present for a constant time period, before a fire decision is made (Fig 1). This setting, for example, is ideal for hotel bedrooms with ensuite shower rooms, the end user can change the setting from smoke 2 to smoke 3 if nuisance alarms are becoming a problem – whilst still offering optimum protection of a smoke detection setting, especially if this is what has been specified. Heat 1: (Rate of Rise) Used where a standard rate of rise detector would normally be used Heat 2: (Standard Fixed Temperature - 58ºC approx) Used where a standard fixed temperature heat detector would normally be fitted, suitable for kitchens etc Heat 3: (High Fixed Temperature - 90ºC approx) Used where a high fixed temperature heat detector would normally be fitted, suitable for boiler rooms etc. You can read the previous article concerning the new Multipoint ASD detectors from Rafiki - or visit the Rafiki conventional fire alarms section on our website for more models and details.

The Rafiki's Multipoint ASD detector range have broken new barriers in fire detection and alarm. Not only does the multipoint offer seven modes of fire detection it also offers an optional built-in sounder and a sounder strobe in a single device. The Rafiki multipoint uses patented advanced optical scatter sensor design along with sophisticated electronic technology to deliver reliable smoke or heat detection, whilst substantially reducing false alarms. The Multipoint ASD retains all the advantages of the original Multipoint detector with a range of additional features to make it a truly market-leading design. "Stealth" Optical Chamber Design The method of optical scatter fire detection is well known. Sensors comprise an optical emitter and a receiver positioned in a sensing chamber. The emitter and receiver are positioned such that there is no line of sight between them, although some light from the emitter does reflect on the walls of the chamber and into the receiver; this is known as standing scatter level. When smoke enters the chamber it increases radiation from the emitter and substantially increases the radiation detected by the receiver, a sensor circuit then triggers an alarm. A disadvantage of this design is that dust, grease etc. enters the chamber and settles on the walls causing the scatter level to increase or decrease depending on the type of contamination. This variation can cause false alarms or can mask the presence of a true alarm condition. Stealth Chamber Rafiki has designed a patented optical scatter smoke sensor that alleviates this problem. This has been achieved by creating a secondary chamber that collects the contamination out of site of the emitter and receiver thereby substantially reducing the incidence of false alarms and improving detection reliability. Multi-Criteria Detector The Rafiki "Multipoint" detector has set new standards in detector technology, using microprocessor control, offering the installer a full range of detection capabilities with audible and visual warning in one compact device. Specifiers and installers who choose the Multipoint detector, do so secure in the knowledge that the fire detection performance of the detector can be matched to the environment in which it is installed – and changed at any time during the lifetime of the installation. The mode of detection required can be simply changed by way of a DIL switch in the detector (configurable via commissioning software on addressable systems).
