MANUALE TECNICO / TECHNICAL MANUAL
HOLA F24EN
HOLA F24EN: remote-supplied 24 Vdc sounder with high-brightness,
low consumption LED flashing unit – programmable alarms and
timings – flash and sound inputs programmable separately – electronic
circuit protected against polarity inversion thanks to a special resin
immersion process.
Three inputs with different sounds for a better distinction of the alarm
stages, input for sound synchronism. Six available sounds.
NOTE: In order to open the sounder remove the led cover twisting a
screw-driver between the led-cover and the sounder-cover as shown in
the picture 1 then unscrew.
