Rafiki Twinflex Fire Alarm System Design Requirements
Determine the number of zones required Based on the recommendations provided in BS 5839, determine the number of zones required to comply with the standard and adequately protect the premises. Generally, at least one zone per floor will be necessary, but other factors such as the floor area and the number of devices that can […]
What batteries do Fike Twinflex fire alarm panels require?
A fire alarm battery is required to maintain the Fike Twinflex system in operation in the event of a mains supply failure. The following batteries are suitable. TwinflexPro2 or TwinflexPro panels Both the TwinflexPro2 and TwinflexPro require a pair of 3ah batteries. For installations where additional standby battery backup is required a battery conversion kit is […]
What are the main features of the Rafiki Twinflex Fire Alarm System?
Two wire installation – The Twinflex Fire Alarm System requires only one circuit per zone to connect all devices (Twinflex Detectors, Twinflex Call Points, Twinflex Sounders and Twinflex Flashers). Installation savings – Savings can be as high as 40% with save on cable, installation time and sounders. Callpoint identification – Twinflex Panels can differentiate between […]
Rafiki Twinflex System Configuration
The Twinflex Detectors and Twinflex Call Points are arranged in zones to enable the location of a fire alarm to be identified. The number of zones depends on the size and the layout of the premises, and the capacity of the Twinflex Control Panel. The number of zones on the panel (2, 4, or 8) […]
Rafiki Twinflex Fire Alarm System Cabling Requirements
The Twinflex Fire Alarm System requires a pair of wires per zone to accommodate the field devices, i.e. Twinflex Detectors, Twinflex Call Points, Twinflex Sounders& Flashers, and Twinflex Output Units. Each zone is wired as a radial circuit, i.e. the wires are terminated at the panel at one end and finish at a device in […]
How many devices can be used on each Fike Twinflex fire alarm system zone?
As a guide the following Twinflex devices can be installed on each Fike Twinflex system zone; 6 x Twinflex Hatari sounders 16 x Twinflex Multipoint detector with sounder (normal volume) 32 x Twinflex Multipoint detector with sounder (low volume) 32 x Twinflex Multipoint detector without sounder 32 x Twinflex call point
Which Rafiki Twinflex Multipoint Detector application mode is most appropriate?
One of the many benefits of the Rafiki Twinflex Fire Alarm System is the unique detector concept whereby a single detector provides up to seven operating modes to suit the application. However, to gain the maximum benefit from this feature, the detector mode must be correctly applied to each specific installation to ensure that the […]
Fike Twinflex Multipoint Detector Modes of Detection
The Fike Twinflex Multipoint Detector has the unique ability to select between different modes of smoke and heat detection using DIL switches on the electronics assembly. This means that the detection mode can be optimised for the location where the detectors are installed during commissioning, or as a result of changes in building use without […]
Fike Twinflex Checkpoint Plus technology helps eliminate the problem of false alarms
Fike Twinflex plus is a patented, 2 wire intelligent fire alarm system suitable for the majority of fire alarm installations. The Twinflex plus also has the option of the added feature of ‘checkpoint’ alarm confirmation. Checkpoint alarm confirmation drastically reduces the disruption and cost associated with false alarms, particularly during the settling-in-period following installation. Introduction of mandatory licensing of […]
