[Notifier - THIẾT BỊ BÁO CHÁY NGOẠI VI LOẠI THƯỜNG] Đầu báo khói quang thường

Đầu báo khói quang và kết hợp quang/nhiệt System Sensor’s i³™ Series đại diện cho một bước tiến đáng kể của dòng báo cháy thường, kết hợp ba tính năng chính: dễ lắp đặt, thông minh, phát hiện nhanh chóng.

Dễ lắp đặt. Đầu báo i³ Series dễ dàng được lắp đặt nhờ thiết kế plug-in của nó. Điều này cho phép người cài đặt có thể lắp trước đế với phần đầu. The large wire-entry port and in-lineterminals provide ample room for neatly routing the wiring inside the base. The base accommodates a variety of backbox mounting methods, as well as direct mounting with drywall anchors. To complete the installation, i³ Series heads plug into the base with a simple Stop-Drop ’N Lock™ action.

Intelligence. Intelligence. i³ Series detectors offer a number of intelligent features to simplify testing and maintenance. Drift compensa- tion and smoothing algorithms, to minimize nuisance alarms, are standard in the i³ Series. When connected to the 2W-MOD loop test/maintenance module, an SFP-2402/-2404 panel,SFP-5UD/10UD, or RP-2001/2002 two-wire i³ detectors are capable of generating a remote maintenance signal when they need cleaning. This signal is indicated by LEDs located at the module and at the panel. To read the sensitivity of i³ detectors, the SENS-RDR is a wireless device that displays sensitivity in terms of percent-per-foot obscuration.

Instant inspection. The i³ Series provides wide-angle red and green LED indicators for instant inspection of detector condi- tion. The LEDs indicate: normal standby, out-of-sensitivity, alarm, or freeze trouble conditions. The “EZ Walk” loop test feature is available on two-wire i³ Series detectors when con- nected to the 2W-MOD loop test/maintenance module. The “EZ Walk” feature verifies the initiating loop wiring by providing LED status indication at each detectorInstant inspection. The i³ Series provides wide-angle red and green LED indicators for instant inspection of detector condi- tion.
