LASS-WSO-NC

Addressable Wall Mount Sounder

LASS WSO NC web

The LASS series Addressable Synchronised Sounders are loop-powered audible alarm devices that plug in to System Sensor analogue addressable detector bases such as the B501AUS.

Each LASS-series alarm device can be individually addressed by a fire alarm control panel over an analogue addressable loop. In a Pertronic F220 system, the control panel’s loop driver board controls the audible signals.

Tones from all LASS alarm devices connected to a single loop driver can be synchronised. An F220 loop driver can control two analogue addressable loops. So, all LASS devices on a pair of loops can be synchronised.

Two audible alarm tones can be controlled by the fire alarm panel. These tones indicate alarm Stage 1 (Evacuate) and alarm Stage 2 (Alert). The pair of tones may be configured from any one of four optional two-stage tone-sets. The sounder’s alarm is internally synchronised with the audible alarm.

LASS series alarm devices are compatible with the optional anti-tamper feature on the B501AUS and compatible detector bases.

The Addressable Synchronised Sounders (LASS-BSO-NC, LASS-WSO-NC) are independently certified as compliant with AS ISO 7240.3:2014.
