VISUAL-ACOUSTIC SIREN
SPLZ-1011

1. General
The SPLZ-1011 outdoor visual-acoustic siren is designed for use in burglary and assault
signaling systems. The signaling function is performed in two ways: visually (by red color
lamp blinking) and acoustically (by a modulated, high-volume sound signal). A xenon lamp
(flash) is the source of light, while the sound signal is generated by means of a piezoelectric
transducer. The design of the siren housing, as well as its inner enclosure made from
galvanized sheet, ensure a high degree of tamper protection (against opening, tearing off
from the base, an attempt to cover the transducer with foam). The electronics board is made
in SMD technology and protected by impregnation against unfavorable effects of weather
conditions, thus ensuring high reliability of the equipment. The SPLZ-1011 housing is made
of the highly impact resistant PC LEXAN polycarbonate, hence it features a high mechanical
strength and guarantees aesthetic appearance of the siren even after many years of
operation.
2. Installation
The siren should be mounted on a flat base in a location as inaccessible as possible to
minimize the tampering risk. The device should be attached to the base by means of screws
and expansion bolts.
Note: Keep a clearance of approx. 4.5cm between the upper edge of siren housing and the
ceiling or other obstacle limiting the mounting position from above. The lack of such
clearance can make the mounting of housing difficult.
The tamper circuit of the siren protects the device against removal of housing or tearing the
unit off the wall. For the circuit to operate correctly, the „S” element must be screwed to the
base.
The siren is fitted with circuit for signaling the attempts to tamper with the transducer using
the sealing foam. The circuit can operate independently or be connected in series with the
device tamper circuit.
