Fungsi D4120 Duct Smoke Detector System Sensor

D4120 Duct Smoke Detector System Sensor adalah pendeteksi asap berbasi 4-wire photoelectric yang dapat diaplikasikan pada kondisi extreme sekalipun. bekerja pada tekanan udara 100-4000 fpm, temperatur -4°F – 158°C, dan rentang kelembapan 0-95 persen. Plugins sensor kepala menawarkan kemampuan untuk mengurangi false alarm dan instalasi, testing dan maintenance sangat mudah. Cover design mengisolasi kepala sensor dari aliran udara yang lambat untuk lebih memudahkan dalam maintenance.

Tombol akses Reset pada D4120 Duct Smoke Detector System Sensor membuat perangkat memungkinakan untuk melakukan pengetesan dengan cover terpasang. tiga DIP switches dapat digunakan untuk mengkonfigurasi beberapa hal, seperti: cover tamper delay, jumlah sensor yang akan dikontrol, dan mematikan saat inisiai trouble tercipta. Masing-masing board memiliki dua LED yang dapat mengindikasikan status dari sensor yang terkonek, hal ini juga sebagai referensi yang dapat dibaca langsung pada cover mengindikasikan system saat standby, maintenance, trouble, dan Alarm.
