General Description
The Sita Sounder/Strobe unit allows for audible and visual 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/Strobe 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

regarding sounder spacing, placement and special applications please refer to BS 5839 Pt1 : 2002 + A2 : 2008.
Device Installation
The base moulding should be positioned so that access to the locking feature is concealed from general view to
lessen the possibility of unauthorised removal of the device.
Drill or break out the cable entry region(s) in the 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
