It suits installers wanting fewer false alarms. It runs on a two wire supply from 8.5 V dc to 33 V dc.\u003c\/p\u003e\u003ch2\u003eKey features\u003c\/h2\u003e\u003cul\u003e\n\u003cli\u003eBetter on dark smoke – improved sensitivity to black smoke\u003c\/li\u003e\n\u003cli\u003eCopes as it ages – compensation for build-up of dirt\u003c\/li\u003e\n\u003cli\u003eFewer nuisance alarms – extra confirmation of smoke before an alarm signal is given\u003c\/li\u003e\n\u003cli\u003eEasy to see from below – integral indicator with 360º visibility\u003c\/li\u003e\n\u003cli\u003eQuick to check – FasTest takes just four seconds to test that it is functioning correctly\u003c\/li\u003e\n\u003cli\u003eShows wiring faults early – StartUp confirms that the detectors are wired in the correct polarity\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch2\u003eFor installers\u003c\/h2\u003e\u003cul\u003e\n\u003cli\u003ePower: 8.5 V dc to 33 V dc.
