Rafiki Twinflex Multipoint ASD Detector Stealth Chamber
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 site between them, although some light from the emitter does reflect on the walls of the chamber and into […]

Simplicity Micro Fire Alarm System & Secure Micro Sounder Bases, the cost effective option for systems requiring a sounder and/or flasher with each detector
The Securetone Micro addressable sounder and combined sounder & flasher bases have been designed for use with the Simplicity Micro Addressable Fire Alarm System. The bases act as an interface between the Simplicity Micro Addressable Fire Alarm Panel and Zeta Conventional Fire Alarm Detectors (these can be either smoke, heat or combined). This will offer […]
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 technology is used in the Rafiki Twinflex Multipoint Detector?
There are two high performance fire sensors incorporated within the Rafiki Multipoint fire detector: Optical scatter smoke sensor Based on a high efficiency infra-red LED and receiver pair, the optical chamber includes two lenses and has been designed to be tolerant against the effects of ambient light, dust and insects, whilst giving a high signal/noise […]
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 […]
