Addressable Base Sounder
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 activated (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, provided that the loop driver is fitted with firmware version 4.08.00 or later. 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. When activated, the anti-tamper feature inhibits unauthorised removal of the alarm device. Note that if an LASS device is used with a B501AP deep base, there will be a 3-4 mm gap between the device and the mounting surface.
The Addressable Synchronised Sounders (LASS-BSO-NC, LASS-WSO-NC) are independently certified as compliant with AS ISO 7240.3:2014.
