The detector is housed in an flameproof enclosure and the air inlet and exhaust ports provide Ex d protection through the use of Flame Arrestors and is supplied with the full compliment of Xtralis VESDA features including multiple alarm levels, AutoLearn, Referencing and comprehensive event logging. The detector is supplied with VESDAnet, the fault tolerant communications protocol, as standard. VESDAnet supports reporting and remote control/diagnostics of the detector from a non-hazardous area allowing easier periodic maintenance reviews without the need to open the Ex d enclosure cover. With VESDAnet, the standard remote module options are available. Remote displays can be used for immediate status reviews displaying alarm levels, smoke levels, common faults and also the ability to remotely reset and isolate the detector. Remote relays provide extensive and flexible relay reporting.
