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.

How Decibel A-Weighting Works and Why It's Important for Fire Alarms

If you've taken alook through our Fire Alarms and Ventilation systems (maybe it's a slow afternoon at the office), you might have noticed that sometimes we give a dB(A) value in the technical information, under something like "sound output." This fire alarm sounder has a sound output of 101 dB(A); on the other hand, there's an extractor fan with less than a quarter of the sound output, at 25 dB(A). Measuring Noise dB(A) stands for Decibel A-weighting - it's a measurement of the level of sound pressure in the air. That measurement is modified so that the measured loudness matches the loudness that is perceived by the human ear as closely as possible. This is opposed to a straight, physical measurement of the sound pressure in the air; the people in charge of taking the measurements try to ensure that the perceived sound stays reasonably constant in all environments. (Strictly speaking, this isn't always possible for a huge number of reasons, but it's close.) Our examples are human-centric applications, after all; workplace noise measurements are also expressed in dB(A) in order to comply with regulations. An A-weighting filter de-emphasises the lower frequencies (pitches) of a sound and emphasises those around 3000-6000 Hertz where the human ear is more sensitive. For the physics geeks in our readership (and we assume there must be a few), Wikipedia has a good primer on the subject of decibel A-weighting, with curves and equations. This gives an easy, single-number measurement of noise level that we can compare with the noise level in the environment. When we need to install a fire alarm, to carry on with our examples, it should be louder than the ambient noise. Using Noise The alarm sounder we mentioned above has a sound output of about 101 dB(A), which is a little bit louder than a newspaper press. The "ultra-quiet" ventilation fan is about as loud as a person whispering to themselves in an art gallery. The measurement in dB(A) allows a contractor to compare the sound output of a thing with the environmental noise level: if the sound output of an alarm sounder is higher than the general level of noise, then the alarm will be heard. If the source output is lower, then it will be masked. Sometimes, the distance from the source is also given. This is useful - even essential - for larger environments, where an alarm sounder might be installed far away from someone working at a factory machine, for instance. Generally, as the distance doubles, the sound level in dB(A) is halved. This should be taken into account when installing an industrial alarm system. Broadly: you'll want to go as loud as possible with the fire alarms (ideally without damaging anybody's hearing!), and as quiet as possible with ventilation fans and other such appliances. It's an interesting experiment and it opens up a whole new can of worms (as if we didn't have enough already) - how loud is your office? Your house? Are you using the right appliances for the noise level?
