GENERAL INFORMATION
The SF120 is a fire alarm siren designed to emit sound and
light signals when triggered off by a fire notification system.
The SF120 consists of a board placed in a box with a lid.
The sound emitter is a piezo-electric type and the light
indicator is a xenon lamp of high luminous intensity. The
lid of the box is of ABS, very strong and contemporary
design. The frequency of the sound emitted by the siren is
within the range of 3,1 - 3,7 kHz. The blinking frequency
of the light indicator is 0,5Hz +/- 20%.
INSTALLATION
Preliminary Preparation
Dismantle the box before attempting to install the siren.
First undo the two front screws on the plastic lid and then
pull out the lid itself.
Use the master form on the back of the cardboard box to
make the necessary openings (three in all) on the wall
where the siren will be mounted.
Mounting and Connecting
Fix the metal bottom of the siren to the wall with adequate
screws.
Connect the two conductors from the fire notification
station to the clamps as shown in Fig. 1.
Place the terminating resistor on the siren clamps.
Completing Installation
Replace the plastic lid. Fix the lid to the metal bottom
with the help of the face screws.
