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 bo with a cover. The bo

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

Initia Preparation

Dismantle the bo before installing the siren. First remove the outer and then the inner

cover of the bo . The flash lamp becomes accessible immediately after the outer bo 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 P ace

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 e ceed the height of 3 m, thus making it difficult for e ternal access attempting to

eliminate the siren.

Mounting

Use the profile board on the back of the cardboard bo to position and drill the necessary

openings (three) on the wall where the siren is going to be mounted.

Prior to mounting the siren bo 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 bo 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 bo and the opening

at the inner end. The battery terminals must

be at the inner side. Fi the bo to the wall

with the help of the three screws.

Ne t 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 bo . See Figure 1.

This adjustment is necessary so as to compensate the surface roughness of the wall.

Notice! Make sure the No. 1 regu ating screw rests on a so id base to avoid any

deviation from the set adjustment!

Configuration

There are two types of connections depending on the drive. Therefore, your siren must be

properly configured prior to connecting the terminals. This is determined by the position of

the J1 jumper. At that, in the case of a double wire connection (no blocking signal) the

jumper must be switched on. With a triple wire connection (with positive blocking signal)

the jumper must remain in switched off position  left in its place, switched to one leg.

Connection

Before applying power to the siren, the alarm system tamper zone can be connected to the

two wires leading to the siren tamper switch. Connection is done according to the J1

jumper position as determined when configuring.

Trip e wire connection

Connect the power of the alarm system to the

GND and +12V terminals. (Fig. 2)

Connect the +12V blocking signal of the alarm

system to the BLOCK terminal.

The siren is activated when the BLOCK terminal

signal is suspended.

Doub e wire connection

Connect the alarm system minus power wire to

the GND terminal. (Fig. 3)

Connect the +12V positive blocking signal of

the alarm system to the +12V terminal.

The siren is activated when the +12V terminal

signal is suspended.

Doub e wire connection without Battery

Connect the alarm system minus power wire

to the GND terminal. (Fig. 4)

Connect the +12V driving signal of the alarm

system to the +12V terminal.

The siren is activated when the +12V driving

signal appears.

P acing the Battery

It should be borne that when placing the battery only one of the two possible options to

position it is correct. For security reasons (e ternal inaccessibility to the battery terminals,

in order not to eliminate the back-up power supply source of the siren) it is good for the

terminals to be at the inner part of the bo . Attach the battery to the bo using the cable

bracing.

Notice! The cab e shoes shou d be connected to the battery. Observe the

b ack and red po arity. The siren has protection, which wi burn out if

these are switched around. The protection can be restored at the company

service office on y.

In case of Doub e wire connection without Battery ensure the battery

cab es are safeguarded.

Comp eting Insta ation

Close the bo with the inner cover first and then the outer cover. Fi the inner cover with the

shorter screws. For the outer cover use the remaining two screws.
