All the connections are Very Low Safety Voltage in terms of the norm EN 60950. The SIREX
electric power must be supplied by a limited power source.

A positive continuous voltage of 9 to 16V on terminal « SIR » allows blocking or resetting the
SIREX. When this voltage disappears, the ringing alarm is activated during 3 minutes in external
modulation and 31 minutes in internal modulation (S3.1) while the flash is activated until the
return of the blocking voltage (for SIREX-F).
WARNING: only the external modulation is
allowed in outdoor space.
Note that during the power up, SIREX does not trigger even if the
blocking voltage is absent. First, all must be armed by applying the blocking signal for at least 1
second. The sound power level of modulation can be reduced (S3.2).
