Maximum of 159 detectors per loop.
The SSF-AS-851R-IV is a waterproof intelligent addressable rate of rise heat detector. The detector is sealed against the entry of moisture to a rating of IP67 and connects directly to the addressable loop without the need for interfacing modules or any additional wiring.
As with all FlashScan heads the detector can be addresses from 1-159 and has twin LED which will flash green when normal and latch red when the detector is in alarm.
Due to the IP67 nature of the product, the detector does not have traditional address wheels. The detector address is set by the use of a hand held programmer (SSF-ADD-PROG) before installation.
