A smouldering fault behind a patch panel won't trigger your building's ceiling detector for minutes. By then the switch is toast. This APC NetBotz smoke sensor sits right next to your sensitive IT gear and flags it early, feeding directly into your NetBotz appliance. The 10 ft cable lets you mount it close to the rack face without a long, unsightly run. Rack mounting brackets and cable ties are in the box so you can get it up and reading in under ten minutes. It supplements your existing life-safety system – it doesn't replace it. Operating range 0–45 °C, 0–95 % humidity. Compatible spare parts: ACF127, W870-8135. Fits the full NetBotz rack family from AP4424 through to AP7551
