Additional devices enhance PAVA operation with speaker line monitoring and reduced cabling. Local control prioritises emergency messages, while adaptive audio keeps announcements clear.
Microphone cabinet PAVA-MC
Secure, fire service-ready metal cabinet for built-in fireman microphone mounting, with locked access using the same key as the EBL system’s CIE.
End of line supervision module ABT-EOL
This module provides continuous loudspeaker line monitoring without extra supervision cabling, reducing installation costs and simplifying maintenance.
Loop isolator IS8200-1
The loop isolator protects voice alarm loudspeaker circuits with continuous short-circuit monitoring, improving reliability and fault tolerance.
Short-circuit isolator driver LM8200
This board monitors up to 4 loop speaker lines, used with IS8200 isolators, helping the system remain reliable in critical voice alarm applications.
Volume controller ABT-REG1
The volume controller allows local adjustment of 100 V loudspeaker volume up to 40W rms, while emergency messages always take priority.
Wall mounted controller WMC
The controller eases daily operation, with a user-friendly LCD touch screen and wireless audio control without needing access to the main control unit.
Noise sensor controller ABT-NSC6
Noise sensor controller that collects data from up to 6 noise sensors to automatically adjust volume, keeping announcements clear and balanced.
Noise sensor indoor ABT-NSM (A)
The indoor noise sensor measures background noise for ABT-NSC6 noise sensor controller, helping PAVA volume adjust automatically up to 300 m.
Noise sensor outdoor ABT-NSM (B)
Outdoor noise sensor for ABT-NSC6 noise sensor controller, measures background noise to help PAVA volume adjust automatically in extreme conditions up to 300 m.
Adaptive audio processor SMART-DU1604
The processor dynamically optimises speech intelligibility and keeps messages clear by processing audio and noise data in real time for up to 16 microphones ANSM-01.
Adaptive microphone aggregation point SMART-AMAP-6
This device processes signals from up to 6 measurement microphones, optimising sound performance with adaptive filtering algorithms over distances up to 300 m.
Adaptive noise sensing microphone SMART-ANSM-01
This microphone measures sound level and frequency from 100 Hz to 10 kHz, ensuring precise, stable acoustic monitoring over long connections up to 300 m.
