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 Sita200plus,
Duonet and Quadnet ranges of control panels 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 to 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 source. For more specific information regarding detector spacing,
placement and special applications please refer to BS5839 Pt1 : 2002 + A2 : 2008.
Detector Installation
Fix the base in a suitable position using the two screw slots provided, remembering to allow enough cable length for
termination. 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, and is to be wired in the form of a screened 2-
core loop returning to the control panel. The use of spurs on this system is not permitted.
Cables may be
terminated into the connectors mounted in the base, as shown below. Care should be taken when terminating
devices to ensure all cables are correctly sleeved and connections are secure. Improper connections will prevent a
system from responding properly in the event of a fire.

Not Used
The Loop +ve (positive) IN and the Loop +ve (positive) OUT connections are split within the base. For cable
continuity readings at the commissioning stage the supplied link must be fitted. Please remember that all high
voltage testing must be carried out before the installation of the electronics, otherwise the electronics will be
damaged. Please also note that the SCRN terminal should only be connected to the loop screen and NOT the
building earth.
