FT143火灾感烟感温探测器(别名，开关量烟感温感探测器，以下简称探测器)适用于商场、宾馆、商店、仓库、银行、通信机房、等民用及工业场所的火灾预报警。探测器具有灵敏度高、稳定可靠、耗电小、美观耐用、使用方便等特点。

一. FT143火灾感烟感温探测器性能：

供电电源： DC9V～DC28V

电流：静态电流 ≤200uA

报警电流 ≤45mA

工作温度： -10℃～+50℃

相对湿度： ≤95%RH(40℃±2℃)

输出形式：声光报警/继电器无源触点（NO/NC可设置）输出。

二.FT143火灾感烟感温探测器功能：

工作：正常情况下,探测器大约每隔6秒指示灯会闪亮一下。探测器自动检测周围环境中的烟雾浓度和温度,并根据使用环境状况进行灵敏度自动补偿。当烟雾浓度或温度接近报警值，探测器加快对温度或烟雾浓度趋势进行智能运算,同时报警指示灯开始闪亮。若运算结果达到或超过报警值,探测器开始声光报警,并启动继电器输出。当周围环境的温度或烟雾浓度降低到报警值以下时,探测器自动恢复正常工作状态。

输出：无源触点输出；触点容量24V/1A(220v/1a)，可通过探测器内部的跳线，设置为常开或常闭触点输出。出厂时跳线默认设置触点为常开。

英文介绍：

1. GENERAL DESCRIPTION

The detectors are photo-electronic detector uses a state of-the-artoptical sensing chamber. This detector is designed to provide open area protection and to be used with most security alarm control panel.
Two LEDs on each detector provide local 360° visible alarm indication. They flash every six seconds indicating that power is applied and the detector is working properly. The LEDs latch on in alarm. LEDs will be off when a trouble condition exists indicating that the detector sensitivity is outside the listed limit. The alarm can be reset only by a momentary power interruption.
The detector that initiated the alarm condition will have its red LED and relays latched until reset by panel.
Heat detector and smoke & heat detector combine a photo electronic sensing chamber and a temperature heat detector.

WARNING
TO PREVENT DETECTOR CONTAMINATION AND SUBSEQUENT WARRANTY CANCELLATION, THE SMOKE
DETECTOR MUST REMAIN COVERED UNTIL THE AREA IS CLEAN AND DUST FREE.
3. INSTALLATION
NOTE: All wiring must conform to applicable local codes, ordinances, and regulations.
INSTALL THE DETECTOR BASE
1. Open area smoke or heat detectors are intended for mounting on a ceiling or a wall in accordance with the fire standard in your country.
2. Attach mounting base to ceiling or wall. The base of the detector can be mounted directly onto an electrical junction box such as an octagonal (75mm, 90mm or100mm), a round (75mm), or a square (100mm) box without using any type of mechanical adapter.
3. Position all wires flat against terminals, and fasten the wires on the terminals, See Figure 1.
4. Terminals function description:
Terminal 1: Relay Output -COM
Terminal 2: Relay Output – NO/NC (default NO)
Terminal 3: DC Power –
Terminal 4: DC Power +
