202-0003 Twinflex Multipoint Detector
202-0001 Twinflex Multipoint Detector
with Sounder
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 2core 1.5mm2 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.

Twinflex Multipoint Detectors can be mixed on the same zone as other types of Twinflex device (eg. Twinflex
Callpoints). The above diagram shows how to make the zone positive, zone negative and screen connections
between the control panel and Twinflex Multipoint Detectors. Refer to the instruction leaflets supplied with other
Twinflex devices for their equivalent wiring/terminal labelling details.
Please note that the SCRN terminal on the detector bases should only be connected to the zone cable screen and
NOT to the building earth. The cable screen is connected to earth at the panel end only, via the zone “SCRN”
terminal (or EARTH terminal on the Twinflex V3 2/4/8 Zone panels). It is important to maintain the screen continuity
in order to protect against data corruption from interference.
Once all testing has been carried out on the cabling and ‘continuity & integrity’ has been proven, the Multipoint unit
may be assembled.
Program the onboard DIL switches as required before inserting the Electronics Module. Then locate the pins and
gently push home the module.
Remember that the device at the end of the line must have its EOL signal activated using the
relevant DIL switch. Do not use a resistor or capacitor (or another manufacturer’s End of Line
device) as the end of line, as this may prevent correct operation of the zone.
The Detector Head may then be offered up and twisted to locate until the catch operates. Remember not to force
this item. If the Electronics Module is correctly located then the Detector Head should locate with very little force.
Tamper Resistance and Head Removal
The Multipoint detector incorporates a tamper resistant locking mechanism that
prevents its removal from the base without the use of a special tool. To remove the
device the tool should be offered up to the detector and turned anti-clockwise
allowing the detector to be removed from the base.
If required the Electronics Module may be removed by
OPTICAL CHAMBER & HEAD
inserting the Key into the triangular slot adjacent to the
LED and then pulling to ease the Module out. Do not
pull on the optical transmitter and receiver pair as you
may misalign them.

DIL Switch Settings
The detector DIL switches may be used to program the operation of
the Multipoint Detector. They may be altered when the device is
removed from the base.
If a heat detection mode is selected then use the ‘HEAT’ labels
supplied to label the base of the detector clearly.
The last device on the circuit must have the EOL signal enabled
(switch number 1 in the ‘ON’ position).
