General Description
The Twinflex Multipoint ASD 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. This device is only compatible with the Twinflex control panels (and
their associated detection and alarm equipment) and may also incorporate a sounder
beacon (ignore all references to sounders/beacons if your device has no
sounder/beacon).
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-
1:2013.
Spacing
Fike recommends spacing detectors in accordance with BS5839-1:2013. 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 BS5839-1:2013.
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 BS5839-1:2013 as well as any special
recommendations documented in the control panel installation manual. The cabling used should be of a 2-core 1.5mm2screened,
fire resistant type (e.g. 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 horizontal 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 ASD Detectors can be mixed on the same zone as other types of Twinflex device (e.g. Twinflex Call-points and
earlier detectors). If mixed with earlier detectors, the zone must be set to ‘CP/DET’ and not ‘CP/SM/HT’. The above diagram shows
how to make the zone positive, zone negative and screen connections between the control panel and Twinflex Multipoint ASD
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.
Please remember that all high voltage testing must be carried out before the installation of the detector base or electronics, as this
will cause damage (a small electronics module is also present in base). Once all testing has been carried out on the cabling and
‘continuity & integrity’ has been proven, the detection base & head may be fitted. Before fitting the detector head program the
device settings via the on-board DIL switches, remembering to set the EOL for the last device.
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.
To install the detection head, locate the pins and gently twist until the unit locks in place.
Tamper Resistance and Head Removal
The ASD 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 attached over the detector
and turned anti-clockwise allowing the detector to be removed from the base.
Remote Indicator
The remote LED terminals (‘Remote LED + / -’) may be used to connect a separate LED
(Pt No. 600-0092). The LED functions are as follows:
•5ms every 5 seconds: End of Line
•5ms every 1.3 seconds: Fault
•350ms every 0.7 seconds: Fire detected by detector
•Continuous: Fire detected by detector and processed at panel
•100uS pulse every 20seconds in standby (2 pulses if set to heat)
Note that the LED does not require a resistor.
DIL Switch Settings
The detector DIL switches may be used to program the operation of the Multipoint ASD 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).
*If the Multipoint ASD Detector is used with the SRP panel, DIL switch 2 must
be set in the OFF position, (Logical Link OFF). DIL switches 6 must be ON & 7
must be OFF, (for continuous sound pattern).
The SRP panel controls the sound pattern so if the Multipoint ASD Detector is set to anything other than continuous sound it will conflict
with the SRP panel.

** Not Approved to EN54-7.
Power Up
The Multipoint detector requires approximately one minute on power up to boot up its processor and settle down to normal
operation. Do not test the detector during this time. Ensure that the Detector Head is already installed when the system is powered
up otherwise a fault condition will be present.
Head Contamination Warnings
If a smoke detector becomes dusty, its operation is affected, either making it more prone to false alarms, or in rare cases reducing
its sensitivity. The Multipoint LED will flash once approximately every 1.3 seconds. At the control panel (V3 panel), the common
‘Fault’ LED will flash, the buzzer will sound and the relevant ‘Zone Fault’ LED will flash at approximately twice the rate of the
buzzer. On the Twinflex Pro panel, the common ‘Fault’ LED will be on, the buzzer will sound and the system indication ‘zone LED
will flash at approximately twice the rate of the buzzer. The display will indicate FAULT 00x OF 00x & Z0x: Zone description and
fault type.
Replacing Contaminated Optical Chambers
The optical chamber within the detector is not user serviceable. When an optical chamber becomes contaminated we recommend
replacing the detector. Cleaning an old chamber is not possible with this device as it is a sealed unit. It is essential that the location
of the contaminated device is verified using the device LED which will flash once approximately every 1.3 seconds.
Beacon Operation (Not EN54-23 Compliant)
The Multipoint ASD may also incorporate a sounder or beacon (ignore all references to sounders / beacons if your device has no
sounder / beacon). If the unit includes a Beacon this consists of a number of high output LEDs mounted beneath a diffusing lens at
the lowest part of the detector.
The beacon will start to operate when the device receives a command to activate its sounder, even if the sound pattern is set to
SP0 - Sounder off. Thus, it is possible for the beacon to provide a discrete warning by setting the sound pattern to SP0.
Testing
We recommend the use of suitable smoke test equipment such as the ‘No Climb’ SOLO 300 tester or an equivalent product. Due to
the fact that the smoke detection modes are all ‘thermally enhanced’, it may be noticeable that on test the devices respond more
slowly than may be expected. This is perfectly normal and is due to the fact that during test there is no additional heat present to
cause the sensitivity to be enhanced.

Smoke mode 3 requires that the concentration of smoke is kept up for a longer period to trigger the device into alarm, so patience
is required. Small regular applications of test smoke are best in order to avoid drenching the detector as this may result in sticky
residues being left behind.
