Product Code: FNM-420-B-RD
This standalone siren connects to an analog addressable fire loop and operates at exposed outdoor locations. With the IP66 housing, it operates in the range of -25 to 70 °C; with 102.5 dB(A) output, it exceeds ambient noise in open areas. DIN tone can be selected from thirty-two options and devices synchronize instantly. With current draw below 4.05 mA, up to 100 sirens fit on a LSN 1500 A loop; the need for additional wiring in large installations is reduced.
