26-1029 Issue 6
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.
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 serial 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 automatically 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. The device should then be turned anti-clockwise allowing it to
be removed from the base.
Device Settings
The sounder modes may be configured using the relevant panel software configuration package (OSP).

See the Engineering & Commissioning Manual for your control panel (Sita, Duonet or Quadnet) for further details of how to
program the above.
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 command 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.
