Cerber SA-09. Indoor siren Instructions for use version 1/ June 2005 DESCRIPTION SA-09 is an accoustic warning unit for indoor use, externally powered, embodying a 12V DC electronic siren activated by means of a separate trigger input whose active level can be user-defined as of negative or positive polarity. SA-09 is protected by a shock resistant hard plastic enclosure. Two tamper switches present on the printed circuit board can signal to an external security equipment the events of the unit lid being removed or the unit being pulled off the wall. SA-09 is a piezo-electric resonator-based siren. TECHNICAL DETAILS Sound pressure: 115 dB @ 1m Supply voltage: 12 V DC nominal (between 10.8 and 14.6 V DC) Average supply current: standby: 1mA; alarm condition: 300mA DEFINING THE TRIGGER SIGNAL LEVEL By placing the JP1 jumper on one of the “+” or “–“ marked positions, the user can define the polarity of the signal applied to the TRIG input as positive (12V) or negative (0V). If the jumper is not placed on either position, the indoor siren will not function. To directly trigger the siren whenever applying the supply voltage, the JP1 jumper will be placed on the “+” position and the “12V” and “TRIG” inputs (see below) will be shorted. CONNECTORS AND WIRING 12V, GND – connect the positive and negative terminals of a 12V DC power supply TRIG – siren triggering input TAMPER – an input connected to both tamper switches of the siren. Connect this input to a 24h loop zone of your alarm system PIEZO – piezo sounder control voltage output, default is connected SA-09. An innovative product of ROEL electronics SA ROEL electronics S.A.
