Description
The advanced design of the smoke inlet of the optical chamber guarantees a very high rejection to the introduction of dust, effectively increasing the time between maintenance periods. An alarm condition is determined when:
a) the level of smoke inside the optical chamber exceeds the alarm threshold or,
b) the level of temperature or the thermal variation versus time exceeds the alarm threshold; – consequently an alarm message is sent to the control panel via an AV wireless translator module.
Communication between the detector and the W2W100/ SGWE100 – module(s) is wireless via ‘Sagittarius’ bidirectional protocol. The radio communication meets the requirements of AS4428.9 and European Standard EN54-25 running at 434 MHz.
