Fike 205-0001 Installation And Maintenance Instructions

General Description
The 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. Digital
communication technology to the control panel is implemented allowing for accurate
data transfer at high transmission speeds.
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.
Spacing
Fike recommends spacing detectors in accordance with any local authority. 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.
Detector Installation
All wiring must be installed in compliance with the recommendations laid out by any local authority as well as any special
recommendations documented in the control panel installation manual. The cabling used should be of a 2-core
1.5mm screened, fire resistant type with the following characteristics:
2
Max Capacitance Core to Screen ...................................................180pF / m
Max Capacitance Core to Core ......................................................100pF / m
Max Inductance ..............................................................................1.0mH / km
Max Resistance Two Core Screened 1.5mm² ................................12.1Ω / km
It 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.
The Loop +ve (positive) IN and the Loop +ve (positive) OUT connections are automatically
joined together (short circuit) by a spring arm between terminals 2 and 3 until the detector is
installed. This allows for cable continuity readings at the commissioning stage.
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.
Once all testing has been carried out on the cabling and continuity & insulation has been
proven, the Multipoint detector head may be fitted. Before installing the head remember
to note the serial number of the device (located on the rear of
the detection head) onto your drawings or configuration sheets to
enable you to prove its location later. The address allocation for
the device is carried out automatically by the control panel whilst in
initialisation mode, so addresses do not need to be set manually.
