Axis AU LogoWireless Multicriteria Detector

The Axis Wireless Heat Enhanced Photoelectric Smoke detector has been approved to the European Standard EN54-5 and EN54-7 directives. 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 European Standard EN54-25 running at 434 MHz to meet Australian requirements.
