INSTALLATION AND MAINTENANCE INSTRUCTIONS
326-0003 Sita Sounder with Deep Base
General Description
The Sita Sounder unit allows for audible indication when the system enters an
alarm condition. This is an addressable unit that attaches to the loop. 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 Sita 200+, Duonet and Quadnet ranges of control panels.
Before Installation
The Sounder 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 device should be installed in compliance with BS 5839 Pt1 : 2002 + A2 : 2008.
Spacing
Fike recommends spacing of sounders in accordance with BS 5839. For more specific information regarding
sounder spacing, placement and special applications please refer to BS 5839 Pt1 : 2002 + A2 : 2008.
Device Installation
Drill the cable entry region(s) in base moulding as required.
Drill out the desired mounting holes through hole / slot guides as required. Affix the base moulding to a flat surface
using a minimum of 2 screws.
All wiring must be installed in compliance with the recommendations laid out by BS 5839 as well as any special
recommendations documented in the control panel installation manual. The cabling used should be of a 2-core
2
1.5mm screened, fire resistant type, with the following characteristics:
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 connector, 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 split within the module. For cable
continuity readings at the commissioning stage they must be temporarily removed and connected through.
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.
