INSTALLATION AND MAINTENANCE INSTRUCTIONS
326-0023 Sita Sounder/Strobe
with Deep Base
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 mus t be ins talled 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/strobes 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
The base moulding should be positioned so that access to the locking screw is concealed from general view to
lessen the possibility of unauthorised removal of the device.
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 recom mendations laid out by BS 5839 as well as any special
recommendations documented in the control panel installation m anual. The cabling used should be of a 2-core
1.5mm
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 correc tly sleeved and connections are secure. Im proper
connections will prevent a system from responding properly in the event of a fire.

See the Engineering & Commissioning Manual for your control panel (Sita, Duonet or Quadnet) for further details of how to
program the above.
continuity readings at the comm issioning stage they must be temporarily removed and connected thr ough. Please
remember that all high voltage testing m ust 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
Sounder/Strobe unit can be assembled.
NOTE: Before installing the Sounder/Strobe remember to note the ser ial number of the device (located on the rear
of the unit) on to your drawings or configuration sheets to enable you to prove its location later. The address
allocation for the device is carried out automatic ally by the control panel whilst in initialisation mode, so addresses
do not need to be set manually. See the system Installation and Operating Instructions for further details.
Tamper Resistance
The unit incorporates a locking screw which helps prevent unauthorised removal from the base. To fit, gently insert
the device positioned so that the alignment mark on the rim is rotated slightly anti-clockwise relative to the
alignment mark on the base. Rotate clockwise until the device drops in and the alignment marks meet. Tighten the
locking screw, but do not over tighten.
To remove the device, unscrew the retaining screw. T he device should then be turned anti-clock wise allowing it to
be removed from the base.
Device Settings
The sounder modes may be configured using the relevant panel software configuration package (OSP).
Beacon Operation
The unit includes a Visual Indication Beacon. This consists of a number of high output LEDs.
The beacon will start to operate when the device receives a comm and to activate its sounder, even if the sound
pattern is set to SP0 - Sounder off. If the beacon only is required to operate, Sound Pattern SP0 must be selected
via the configuration software.
Power Up
The Sita Sounder/Strobe requires approximately one minute on power up to boot up its processor, charge for alarm
operation and settle down to normal operation. Do not sound the alarms within the first minute after initializing the
loop.
