INSTALLATION GUIDE

GENERAL INFORMATION

SR 120 is an outdoor self-protected siren basically intended to emit sound signals when
triggered by an alarm system. It also has a light indicator  a flash lamp, which has two
options  halogen or sulphide. SR 120 is on a circuit board placed in a box with a cover. The box
cover is either ABS or polycarbonate of high toughness and modern design. Inside there is
an additional second metal cover (inner cover). SR 120 can be installed both outdoors and
indoors. The audio frequency of the siren signal is within the range of 1.8  3.3 kHz.

The universal nature of operation makes SR 120 compatible with all types of alarm systems,
which provide a power supply and drive of 12 V.

Product Identification

SR 120 - Automatically blocking siren with sulphide flash lamp
SR 120B - Automatically blocking siren with halogen flash lamp

The siren comes in several options depending on the type of lamp, type and design of the
circuit board.

INSTALLATION

Initial Preparation

Dismantle the box before installing the siren. First remove the outer and then the inner
cover of the box. The flash lamp becomes accessible immediately after the outer box is
removed. It must not be touched by hand. Carefully, without touching it, remove the inner
cover. Keep the screws and remember that the longer ones belong to the outer cover and
the shorter to the inner cover.

Choosing a Mounting Place

It is important to choose an appropriate place to mount the siren. A hood or a balcony is
suitable in order to avoid direct impact of outdoor weather conditions on the siren. The spot
should exceed the height of 3 m, thus making it difficult for external access attempting to
eliminate the siren.

Mounting

Use the profile board on the back of the cardboard box to position and drill the necessary
openings (three) on the wall where the siren is going to be mounted.

Prior to mounting the siren box on the wall, the cable bracing for attaching the battery must
be prepared. Therefore, pass it through the opening specially made for the purpose at the
bottom of the box without closing it. At that, the smooth side of the bracing must remain on
the outer side and the indented side must touch the battery. The lash of the bracing remains

at the outer end of the box and the opening
at the inner end. The battery terminals must
be at the inner side. Fix the box to the wall
with the help of the three screws.



Next adjust the tamper switch. This is done
with the help of a screw to regulate the strip

so it remains at a height level of rim 2 of
the metal box. See Figure 1.
