INSTALLATION AND MAINTENANCE INSTRUCTIONS
202-0003 Twinflex Multipoint Detector
202-0001 Twinflex Multipoint Detector
with Sounder
26-0027 Issue 12
General Description
The Multipoint is a plug-in type smoke detector that utilises a photo-electric sensing
chamber to make a measurement corresponding to smoke density. The device also
incorporates a thermistor sensing circuit to allow for accurate heat measurement. These
elements allow the device to be configured to a smoke, heat or combined setting. Digital
communication technology to the control panel is implemented allowing for accurate data
transfer at high transmission speeds. This device is only compatible with the Twinflex
control panels (and their associated detection and alarm equipment) and may also
incorporate a sounder (ignore all references to sounders if your device has no sounder).
Before Installation
The detector must be installed in compliance with the control panel installation manual. The installation must also
meet the requirements of any local authority. For maximum performance the detector should be installed in
compliance with BS5839 Pt1 : 2002 + A2 : 2008.
Spacing
Fike recommends spacing detectors in accordance with BS5839 Pt1. Due to the effects of IR and possible
magnetic interference, detectors should not be fitted any closer than 500mm (preferably 1000mm) to a light fitting or
any other source of IR or EMI. In addition to this recommendation the device should be mounted so that the
indication LED is facing towards the light fitting. For more specific information regarding detector spacing,
placement and special applications please refer to BS5839 Pt1 : 2002 + A2 : 2008.
Note: As with other optical detectors, this device should not be located where subjected to high levels or pulses of
light or infra red light, as this may cause false alarms or faults.
Detector Installation
All wiring must be installed in compliance with the recommendations laid out by BS5839 Pt1 : 2002 as well as any
special recommendations documented in the control panel installation manual.
The cabling used should be of a 2-
core 1.5mm
2
screened, fire resistant type (e.g. MICC or FP200 equivalent), and is to be wired in the form of a
screened 2-core radial circuit (with no spurs) from the control panel, terminating at the last (“End of Line”) device.
Fix the detector base in a suitable position using the two screw slots provided, remembering to allow enough cable
length for termination. You may then terminate your cables directly into the terminal block according to the terminal
labels. It is important to maintain the screen continuity in order to protect against data corruption from interference.
