SNA60-3

Sound level limiter - Cut energy sanction
Standard NF S31-122-1-2017 / class 1a


Specially designed for halls, rooms for rent, coffee concerts, restaurants ...

SNA60-3 is a sound level controller designed for rooms without sound system (theaters, rooms for rent, restaurants ...), when the only control is the power supply switch off, penalty in accordance with decree 98-1143. The SNA60-3 is also consistent with the standard NF S31-122-1-2017 in category 1a.

Its innovative side is presentation in a housing provided for attachment to a DIN rail or Omega rail 11 modules. This will make it very easy for the integrator to position it in a electrical cabinet, allowing a very short wiring at energy and power switch.

The SNA60-3 continuously performs acoustic pressure measuring "Leq". Acoustic moving average is configurable in level and time. The SNA60-3 selects different sound pressure levels depending on the time and according to opening contacts windows/doors. The sound pressure measurement is effected by a a dedicated omnidirectional sensor.

• If the pressure level selected after the specified time is exceeded, the penalty occurs as a 10 seconds power cut.
• A second overflow will be punished in the same way. The cut may be permanent or not (after the third overflow on one hour at the option of the installer or operator).
• No specific software

The SNA60-3 has an internal self acoustic verification in accordance with NF S31-122-1-2017 standard. So it checks complete system integrity, to avoid fraudulent manipulation. It provides a dry loop for controlling via a power switch, the power supply of mobile sound.
